In particular, in close confinements, such as those encountered by dense cell populations during development or regeneration, collective migration can only arise coordinately. Yet, how individuals unify their velocities is often not understood. Focusing on a finite number of cells in circular confinements, we identify waves of polymerizing actin that function as a pacemaker governing the speed of individual cells. We show that the onset of collective motion coincides with the synchronization of the wave nucleation frequencies across the population. Employing a simpler and more readily accessible mechanical model system of active spheres, we identify the synchronization of the individuals’ internal oscillators as one of the essential requirements to reach the corresponding collective state. The mechanical ‘toy’ experiment illustrates that the global synchronous state is achieved by nearest neighbor coupling. We suggest by analogy that local coupling and the synchronization of actin waves are essential for the emergent, self-organized motion of cell collectives."}],"type":"journal_article","fulldoi":"https://doi.org/10.1038/s41467-023-41432-1","author":[{"last_name":"Riedl","id":"3BE60946-F248-11E8-B48F-1D18A9856A87","first_name":"Michael","full_name":"Riedl, Michael","orcid":"0000-0003-4844-6311"},{"first_name":"Isabelle D","full_name":"Mayer, Isabelle D","last_name":"Mayer","id":"61763940-15b2-11ec-abd3-cfaddfbc66b4"},{"last_name":"Merrin","id":"4515C308-F248-11E8-B48F-1D18A9856A87","first_name":"Jack","full_name":"Merrin, Jack","orcid":"0000-0001-5145-4609"},{"orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","full_name":"Sixt, Michael K","first_name":"Michael K"},{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","last_name":"Hof","first_name":"Björn","full_name":"Hof, Björn","orcid":"0000-0003-2057-2754"}],"month":"09","article_number":"5633","ec_funded":1,"ddc":["530","570"],"article_type":"original","language":[{"iso":"eng"}],"external_id":{"isi":["001087583700030"],"pmid":["37704595"]},"file":[{"date_updated":"2023-09-25T08:32:37Z","content_type":"application/pdf","file_name":"2023_NatureComm_Riedl.pdf","date_created":"2023-09-25T08:32:37Z","file_id":"14366","access_level":"open_access","success":1,"creator":"dernst","checksum":"82d2d4ad736cc8493db8ce45cd313f7b","file_size":2317272,"relation":"main_file"}],"publication_identifier":{"eissn":["2041-1723"]},"pmid":1,"has_accepted_license":"1","publication_status":"published","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"M-Shop"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"volume":14,"department":[{"_id":"MiSi"},{"_id":"NanoFab"},{"_id":"BjHo"}],"citation":{"apa":"Riedl, M., Mayer, I.

Whereas it is well established that single-cell migration is often guided by gradients of chemokines and other chemoattractants, it remains poorly understood how these gradients are generated, maintained, and modulated. By combining experimental data with theory on leukocyte chemotaxis guided by the G protein–coupled receptor (GPCR) CCR7, we demonstrate that in addition to its role as the sensory receptor that steers migration, CCR7 also acts as a generator and a modulator of chemotactic gradients. Upon exposure to the CCR7 ligand CCL19, dendritic cells (DCs) effectively internalize the receptor and ligand as part of the canonical GPCR desensitization response. We show that CCR7 internalization also acts as an effective sink for the chemoattractant, dynamically shaping the spatiotemporal distribution of the chemokine. This mechanism drives complex collective migration patterns, enabling DCs to create or sharpen chemotactic gradients. We further show that these self-generated gradients can sustain the long-range guidance of DCs, adapt collective migration patterns to the size and geometry of the environment, and provide a guidance cue for other comigrating cells. Such a dual role of CCR7 as a GPCR that both senses and consumes its ligand can thus provide a novel mode of cellular self-organization.","lang":"eng"}],"isi":1,"ec_funded":1,"article_number":"adc9584","related_material":{"record":[{"status":"public","id":"14279","relation":"research_data"},{"status":"public","id":"14697","relation":"dissertation_contains"},{"status":"public","id":"19745","relation":"dissertation_contains"}]},"month":"09","author":[{"id":"2CC12E8C-F248-11E8-B48F-1D18A9856A87","last_name":"Alanko","full_name":"Alanko, Jonna H","first_name":"Jonna H","orcid":"0000-0002-7698-3061"},{"orcid":"0000-0003-0506-4217","full_name":"Ucar, Mehmet C","first_name":"Mehmet C","id":"50B2A802-6007-11E9-A42B-EB23E6697425","last_name":"Ucar"},{"orcid":"0000-0002-8518-5926","first_name":"Nikola","full_name":"Canigova, Nikola","last_name":"Canigova","id":"3795523E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Stopp, Julian A","first_name":"Julian A","id":"489E3F00-F248-11E8-B48F-1D18A9856A87","last_name":"Stopp"},{"id":"346C1EC6-F248-11E8-B48F-1D18A9856A87","last_name":"Schwarz","full_name":"Schwarz, Jan","first_name":"Jan"},{"orcid":"0000-0001-5145-4609","last_name":"Merrin","id":"4515C308-F248-11E8-B48F-1D18A9856A87","first_name":"Jack","full_name":"Merrin, Jack"},{"first_name":"Edouard B","full_name":"Hannezo, Edouard B","last_name":"Hannezo","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6005-1561"},{"orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","first_name":"Michael K","full_name":"Sixt, Michael K"}],"scopus_import":"1","publisher":"American Association for the Advancement of Science","intvolume":"         8","date_published":"2023-09-01T00:00:00Z","title":"CCR7 acts as both a sensor and a sink for CCL19 to coordinate collective leukocyte migration","article_processing_charge":"No","doi":"10.1126/sciimmunol.adc9584","quality_controlled":"1","corr_author":"1","acknowledgement":"We thank I. de Vries and the Scientific Service Units (Life Sciences, Bioimaging, Nanofabrication, Preclinical and Miba Machine Shop) of the Institute of Science and Technology Austria for excellent support, as well as all the rotation students assisting in the laboratory work (B.

While moving, immune cells efficiently traverse microenvironments composed of tissue cells and extracellular fibers, which together form complex environments of various porosity, stiffness, topography, and chemical composition. In this protocol we describe experimental procedures to investigate immune cell migration through microenvironments of heterogeneous porosity. In particular, we describe micro-channels, micro-pillars, and collagen networks as cell migration paths with alternative pore size choices. Employing micro-channels or micro-pillars that divide at junctions into alternative paths with initially differentially sized pores allows us to precisely (1) measure the cellular translocation time through these porous path junctions, (2) quantify the cellular preference for individual pore sizes, and (3) image cellular components like the nucleus and the cytoskeleton. This reductionistic experimental setup thus can elucidate how immune cells perform decisions in complex microenvironments of various porosity like the interstitium. The setup further allows investigation of the underlying forces of cellular squeezing and the consequences of cellular deformation on the integrity of the cell and its organelles. As a complementary approach that does not require any micro-engineering expertise, we describe the usage of three-dimensional collagen networks with different pore sizes. Whereas we here focus on dendritic cells as a model for motile immune cells, the described protocols are versatile as they are also applicable for other immune cell types like neutrophils and non-immune cell types such as mesenchymal and cancer cells. In summary, we here describe protocols to identify the mechanisms and principles of cellular probing, decision making, and squeezing during cellular movement through microenvironments of heterogeneous porosity.","lang":"eng"}],"author":[{"full_name":"Kroll, Janina","first_name":"Janina","last_name":"Kroll"},{"first_name":"Mauricio J.A.","full_name":"Ruiz-Fernandez, Mauricio J.A.","last_name":"Ruiz-Fernandez"},{"full_name":"Braun, Malte B.","first_name":"Malte B.","last_name":"Braun"},{"last_name":"Merrin","id":"4515C308-F248-11E8-B48F-1D18A9856A87","first_name":"Jack","full_name":"Merrin, Jack","orcid":"0000-0001-5145-4609"},{"orcid":"0000-0003-2856-3369","full_name":"Renkawitz, Jörg","first_name":"Jörg","last_name":"Renkawitz","id":"3F0587C8-F248-11E8-B48F-1D18A9856A87"}],"month":"04","article_number":"e407","scopus_import":"1","intvolume":"         2","date_published":"2022-04-05T00:00:00Z","title":"Quantifying the probing and selection of microenvironmental pores by motile immune cells","publisher":"Wiley","quality_controlled":"1","article_processing_charge":"No","doi":"10.1002/cpz1.407","user_id":"0043cee0-e5fc-11ee-9736-f83bc23afbf0","acknowledgement":"We thank Kasia Stefanowski for excellent technical assistance, and the Core Facility Bioimaging of the Biomedical Center (BMC) of the Ludwig-Maximilian University for excellent support.

In contrast, many real-world chaotic phenomena, e.g., weather, arise in systems with many (formally infinite) degrees of freedom, which limits direct quantitative analysis of such systems using chaos theory. In the present work, we demonstrate that the hydrodynamic pilot-wave systems offer a bridge between low- and high-dimensional chaotic phenomena by allowing for a systematic study of how the former connects to the latter. Specifically, we present experimental results, which show the formation of low-dimensional chaotic attractors upon destabilization of regular dynamics and a final transition to high-dimensional chaos via the merging of distinct chaotic regions through a crisis bifurcation. Moreover, we show that the post-crisis dynamics of the system can be rationalized as consecutive scatterings from the nonattracting chaotic sets with lifetimes following exponential distributions.

Here we present a strategy using finite-element method (FEM) simulations to determine the Green's function of the KPFM probe/insulator/ground system, which allows us to quantitatively extract surface charge. Testing our approach with synthetic data, we find that accounting for the atomic force microscope (AFM) tip, cone, and cantilever is necessary to recover a known input and that existing methods lead to gross miscalculation or even the incorrect sign of the underlying charge. Applying it to experimental data, we demonstrate its capacity to extract realistic surface charge densities and fine details from contact-charged surfaces. Our method gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative charge data over a range of experimental conditions, enabling quantitative CE at the nanoscale.","lang":"eng"}],"ec_funded":1,"author":[{"id":"6313aec0-15b2-11ec-abd3-ed67d16139af","last_name":"Pertl","first_name":"Felix","full_name":"Pertl, Felix","orcid":"0000-0003-0463-5794"},{"id":"4B807D68-AE37-11E9-AC72-31CAE5697425","last_name":"Sobarzo Ponce","full_name":"Sobarzo Ponce, Juan Carlos A","first_name":"Juan Carlos A"},{"full_name":"Shafeek, Lubuna B","first_name":"Lubuna B","last_name":"Shafeek","id":"3CD37A82-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7180-6050"},{"full_name":"Cramer, Tobias","first_name":"Tobias","last_name":"Cramer"},{"orcid":"0000-0002-2299-3176","first_name":"Scott R","full_name":"Waitukaitis, Scott R","id":"3A1FFC16-F248-11E8-B48F-1D18A9856A87","last_name":"Waitukaitis"}],"month":"12","related_material":{"record":[{"status":"public","id":"20203","relation":"dissertation_contains"},{"relation":"dissertation_contains","status":"public","id":"22684"}]},"article_number":"125605","scopus_import":"1","date_published":"2022-12-29T00:00:00Z","title":"Quantifying nanoscale charge density features of contact-charged surfaces with an FEM/KPFM-hybrid approach","intvolume":"         6","publisher":"American Physical Society","corr_author":"1","quality_controlled":"1","doi":"10.1103/PhysRevMaterials.6.125605","article_processing_charge":"No","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant Agreement\r\nNo. 949120).

Here, we show that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness requires neither force sensing via the nucleus nor adhesive interactions with a substrate. Upon global compression of the cell body as well as local indentation of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into dot-like structures, providing activation platforms for Arp2/3 nucleated actin patches. These patches locally push against the external load, which can be obstructing collagen fibers or other cells, and thereby create space to facilitate forward locomotion. We show in vitro and in vivo that this WASp function is rate limiting for ameboid leukocyte migration in dense but not in loose environments and is required for trafficking through diverse tissues such as skin and lymph nodes.","lang":"eng"}],"ec_funded":1,"month":"01","author":[{"full_name":"Gaertner, Florian","first_name":"Florian","last_name":"Gaertner"},{"orcid":"0000-0003-1681-508X","id":"26E95904-5160-11E9-9C0B-C5B0DC97E90F","last_name":"Dos Reis Rodrigues","first_name":"Patricia","full_name":"Dos Reis Rodrigues, Patricia"},{"id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","last_name":"De Vries","first_name":"Ingrid","full_name":"De Vries, Ingrid"},{"last_name":"Hons","id":"4167FE56-F248-11E8-B48F-1D18A9856A87","full_name":"Hons, Miroslav","first_name":"Miroslav","orcid":"0000-0002-6625-3348"},{"last_name":"Aguilera","first_name":"Juan","full_name":"Aguilera, Juan"},{"orcid":"0000-0003-4844-6311","last_name":"Riedl","id":"3BE60946-F248-11E8-B48F-1D18A9856A87","full_name":"Riedl, Michael","first_name":"Michael"},{"orcid":"0000-0002-1073-744X","id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","last_name":"Leithner","first_name":"Alexander F","full_name":"Leithner, Alexander F"},{"orcid":"0000-0003-1671-393X","full_name":"Tasciyan, Saren","first_name":"Saren","id":"4323B49C-F248-11E8-B48F-1D18A9856A87","last_name":"Tasciyan"},{"full_name":"Kopf, Aglaja","first_name":"Aglaja","id":"31DAC7B6-F248-11E8-B48F-1D18A9856A87","last_name":"Kopf","orcid":"0000-0002-2187-6656"},{"first_name":"Jack","full_name":"Merrin, Jack","id":"4515C308-F248-11E8-B48F-1D18A9856A87","last_name":"Merrin","orcid":"0000-0001-5145-4609"},{"orcid":"0000-0002-9438-4783","id":"39C5A68A-F248-11E8-B48F-1D18A9856A87","last_name":"Zheden","full_name":"Zheden, Vanessa","first_name":"Vanessa"},{"orcid":"0000-0001-9735-5315","full_name":"Kaufmann, Walter","first_name":"Walter","last_name":"Kaufmann","id":"3F99E422-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0001-9843-3522","full_name":"Hauschild, Robert","first_name":"Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","last_name":"Hauschild"},{"orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","first_name":"Michael K","full_name":"Sixt, Michael K"}],"related_material":{"record":[{"status":"public","id":"20149","relation":"dissertation_contains"},{"status":"public","id":"12726","relation":"dissertation_contains"},{"id":"14530","status":"public","relation":"dissertation_contains"},{"relation":"dissertation_contains","id":"12401","status":"public"}]},"page":"47-62.e9","scopus_import":"1","date_published":"2022-01-10T00:00:00Z","title":"WASp triggers mechanosensitive actin patches to facilitate immune cell migration in dense tissues","intvolume":"        57","publisher":"Cell Press","corr_author":"1","quality_controlled":"1","doi":"10.1016/j.devcel.2021.11.024","article_processing_charge":"No","acknowledgement":"We thank N.

Here, we demonstrate focusing of in-plane hyperbolic PhPs propagating along thin slabs of α-MoO3. To that end, we developed metallic nanoantennas of convex geometries for both efficient launching and focusing of the polaritons. The foci obtained exhibit enhanced near-field confinement and absorption compared to foci produced by in-plane isotropic PhPs. Foci sizes as small as λp/4.5 = λ0/50 were achieved (λp is the polariton wavelength and λ0 is the photon wavelength).

A prominent example of this is the response to gravity, in which shoots bend up and roots bend down1. This paradox is based on opposite effects of the phytohormone auxin, which promotes cell expansion in shoots while inhibiting it in roots via a yet unknown cellular mechanism2. Here, by combining microfluidics, live imaging, genetic engineering and phosphoproteomics in Arabidopsis thaliana, we advance understanding of how auxin inhibits root growth. We show that auxin activates two distinct, antagonistically acting signalling pathways that converge on rapid regulation of apoplastic pH, a causative determinant of growth. Cell surface-based TRANSMEMBRANE KINASE1 (TMK1) interacts with and mediates phosphorylation and activation of plasma membrane H+-ATPases for apoplast acidification, while intracellular canonical auxin signalling promotes net cellular H+ influx, causing apoplast alkalinization. Simultaneous activation of these two counteracting mechanisms poises roots for rapid, fine-tuned growth modulation in navigating complex soil environments.","lang":"eng"}],"isi":1,"fulldoi":"https://doi.org/10.1038/s41586-021-04037-6","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We thank N.

Particularly, polar vdW crystals, such as hexagonal boron nitride (h-BN), alpha-molybdenum trioxide (α-MoO3) or alpha-vanadium pentoxide (α-V2O5), have received significant attention in nano-optics, since they support phonon polaritons (PhPs)―light coupled to lattice vibrations― with strong electromagnetic confinement and low optical losses. Recently, correlative far- and near-field studies of α-MoO3 have been demonstrated as an effective strategy to accurately extract the permittivity of this material. Here, we use this accurately characterized and low-loss polaritonic material to sense its local dielectric environment, namely silica (SiO2), one of the most widespread substrates in nanotechnology. By studying the propagation of PhPs on α-MoO3 flakes with different thicknesses laying on SiO2 substrates via near-field microscopy (s-SNOM), we extract locally the infrared permittivity of SiO2. Our work reveals PhPs nanoimaging as a versatile method for the quantitative characterization of the local optical properties of dielectric substrates, crucial for understanding and predicting the response of nanomaterials and for the future scalability of integrated nanophotonic devices.

However, these polaritons present a crucial limitation: their directional propagation is intrinsically determined by the crystal structure of the host material, imposing forbidden directions of propagation. Here, we demonstrate that directional polaritons (in-plane hyperbolic phonon polaritons) in a vdW crystal (α-phase molybdenum trioxide) can be directed along forbidden directions by inducing an optical topological transition, which emerges when the slab is placed on a substrate with a given negative permittivity (4H–silicon carbide). By visualizing the transition in real space, we observe exotic polaritonic states between mutually orthogonal hyperbolic regimes, which unveil the topological origin of the transition: a gap opening in the dispersion. This work provides insights into optical topological transitions in vdW crystals, which introduce a route to direct light at the nanoscale."}],"file_date_updated":"2021-04-19T11:17:29Z","type":"journal_article","fulldoi":"https://doi.org/10.1126/sciadv.abf2690","acknowledgement":"G.Á.-P. and J.T.-G. acknowledge support through the Severo Ochoa Program from the government of the Principality of Asturias (grant nos.

In one, the inductor is replaced by a nonlinear Josephson junction to realize the widely used charge qubits with a compact phase variable and a discrete charge wave function. In the other, the junction is added in parallel, which gives rise to an extended phase variable, continuous wave functions, and a rich energy-level structure due to the loop topology. While the corresponding rf superconducting quantum interference device Hamiltonian was introduced as a quadratic quasi-one-dimensional potential approximation to describe the fluxonium qubit implemented with long Josephson-junction arrays, in this work we implement it directly using a linear superinductor formed by a single uninterrupted aluminum wire. We present a large variety of qubits, all stemming from the same circuit but with drastically different characteristic energy scales. This includes flux and fluxonium qubits but also the recently introduced quasicharge qubit with strongly enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion. The use of a geometric inductor results in high reproducibility of the inductive energy as guaranteed by top-down lithography—a key ingredient for intrinsically protected superconducting qubits."}],"isi":1,"ec_funded":1,"related_material":{"record":[{"relation":"research_data","id":"13057","status":"public"},{"status":"public","id":"9920","relation":"dissertation_contains"},{"relation":"dissertation_contains","status":"public","id":"17133"}]},"month":"11","author":[{"orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda","first_name":"Matilda","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","last_name":"Peruzzo"},{"orcid":"0000-0001-6937-5773","last_name":"Hassani","id":"2AED110C-F248-11E8-B48F-1D18A9856A87","first_name":"Farid","full_name":"Hassani, Farid"},{"first_name":"Gregory","full_name":"Szep, Gregory","last_name":"Szep"},{"id":"42F71B44-F248-11E8-B48F-1D18A9856A87","last_name":"Trioni","first_name":"Andrea","full_name":"Trioni, Andrea"},{"id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87","last_name":"Redchenko","full_name":"Redchenko, Elena","first_name":"Elena"},{"id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87","last_name":"Zemlicka","first_name":"Martin","full_name":"Zemlicka, Martin","orcid":"0009-0005-0878-3032"},{"first_name":"Johannes M","full_name":"Fink, Johannes M","last_name":"Fink","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X"}],"page":"040341","scopus_import":"1","publisher":"American Physical Society","intvolume":"         2","title":"Geometric superinductance qubits: Controlling phase delocalization across a single Josephson junction","date_published":"2021-11-24T00:00:00Z","article_processing_charge":"No","doi":"10.1103/PRXQuantum.2.040341","quality_controlled":"1","corr_author":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We thank W.

Group IV hole spin qubits have moved into the focus of interest due to the ease of operation and compatibility with Si technology. In addition, Ge offers the option for monolithic superconductor-semiconductor integration. Here we demonstrate a hole spin qubit operating at fields below 10 mT, the critical field of Al, by exploiting the large out-of-plane hole g-factors in planar Ge and by encoding the qubit into the singlet-triplet states of a double quantum dot. We observe electrically controlled X and Z-rotations with tunable frequencies exceeding 100 MHz and dephasing times of 1μs which we extend beyond 15μs with echo techniques. These results show that Ge hole singlet triplet qubits outperform their electronic Si and GaAs based counterparts in speed and coherence, respectively. In addition, they are on par with Ge single spin qubits, but can be operated at much lower fields underlining their potential for on chip integration with superconducting technologies.","lang":"eng"}],"isi":1,"fulldoi":"https://doi.org/10.1038/s41563-021-01022-2","type":"journal_article"},{"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2693-5015"]},"acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"M-Shop"},{"_id":"Bio"}],"publication_status":"draft","department":[{"_id":"JiFr"},{"_id":"NanoFab"}],"citation":{"apa":"Li, L., Verstraeten, I., Roosjen, M., Takahashi, K., Rodriguez Solovey, L., Merrin, J., … Friml, J.

A showcase is response to gravity, where shoots bend up and roots down1. This paradox is based on opposite effects of the phytohormone auxin, which promotes cell expansion in shoots, while inhibiting it in roots via a yet unknown cellular mechanism2. Here, by combining microfluidics, live imaging, genetic engineering and phospho-proteomics in Arabidopsis thaliana, we advance our understanding how auxin inhibits root growth. We show that auxin activates two distinct, antagonistically acting signalling pathways that converge on the rapid regulation of the apoplastic pH, a causative growth determinant. Cell surface-based TRANSMEMBRANE KINASE1 (TMK1) interacts with and mediates phosphorylation and activation of plasma membrane H+-ATPases for apoplast acidification, while intracellular canonical auxin signalling promotes net cellular H+-influx, causing apoplast alkalinisation. The simultaneous activation of these two counteracting mechanisms poises the root for a rapid, fine-tuned growth modulation while navigating complex soil environment."}],"fulldoi":"https://doi.org/10.21203/rs.3.rs-266395/v3","type":"preprint","article_number":"266395","related_material":{"record":[{"id":"10223","status":"public","relation":"later_version"},{"id":"10083","status":"public","relation":"dissertation_contains"}]},"author":[{"id":"367EF8FA-F248-11E8-B48F-1D18A9856A87","last_name":"Li","full_name":"Li, Lanxin","first_name":"Lanxin","orcid":"0000-0002-5607-272X"},{"orcid":"0000-0001-7241-2328","id":"362BF7FE-F248-11E8-B48F-1D18A9856A87","last_name":"Verstraeten","full_name":"Verstraeten, Inge","first_name":"Inge"},{"first_name":"Mark","full_name":"Roosjen, Mark","last_name":"Roosjen"},{"last_name":"Takahashi","first_name":"Koji","full_name":"Takahashi, Koji"},{"orcid":"0000-0002-7244-7237","id":"3922B506-F248-11E8-B48F-1D18A9856A87","last_name":"Rodriguez Solovey","full_name":"Rodriguez Solovey, Lesia","first_name":"Lesia"},{"full_name":"Merrin, Jack","first_name":"Jack","id":"4515C308-F248-11E8-B48F-1D18A9856A87","last_name":"Merrin","orcid":"0000-0001-5145-4609"},{"last_name":"Chen","first_name":"Jian","full_name":"Chen, Jian"},{"last_name":"Shabala","full_name":"Shabala, Lana","first_name":"Lana"},{"last_name":"Smet","first_name":"Wouter","full_name":"Smet, Wouter"},{"last_name":"Ren","full_name":"Ren, Hong","first_name":"Hong"},{"full_name":"Vanneste, Steffen","first_name":"Steffen","last_name":"Vanneste"},{"full_name":"Shabala, Sergey","first_name":"Sergey","last_name":"Shabala"},{"last_name":"De Rybel","first_name":"Bert","full_name":"De Rybel, Bert"},{"first_name":"Dolf","full_name":"Weijers, Dolf","last_name":"Weijers"},{"last_name":"Kinoshita","full_name":"Kinoshita, Toshinori","first_name":"Toshinori"},{"first_name":"William M.","full_name":"Gray, William M.","last_name":"Gray"},{"last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jiří","first_name":"Jiří","orcid":"0000-0002-8302-7596"}],"month":"09","ec_funded":1},{"article_number":"e2113046118","related_material":{"record":[{"relation":"research_data","id":"14988","status":"public"},{"relation":"dissertation_contains","id":"14510","status":"public"}],"link":[{"url":"https://doi.org/10.1101/2021.04.26.441441","relation":"earlier_version"}]},"author":[{"orcid":"0000-0002-2739-8843","full_name":"Johnson, Alexander J","first_name":"Alexander J","id":"46A62C3A-F248-11E8-B48F-1D18A9856A87","last_name":"Johnson"},{"last_name":"Dahhan","full_name":"Dahhan, Dana A","first_name":"Dana A"},{"orcid":"0000-0002-2198-0509","full_name":"Gnyliukh, Nataliia","first_name":"Nataliia","id":"390C1120-F248-11E8-B48F-1D18A9856A87","last_name":"Gnyliukh"},{"full_name":"Kaufmann, Walter","first_name":"Walter","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","last_name":"Kaufmann","orcid":"0000-0001-9735-5315"},{"orcid":"0000-0002-9438-4783","first_name":"Vanessa","full_name":"Zheden, Vanessa","last_name":"Zheden","id":"39C5A68A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Costanzo, Tommaso","first_name":"Tommaso","id":"D93824F4-D9BA-11E9-BB12-F207E6697425","last_name":"Costanzo","orcid":"0000-0001-9732-3815"},{"first_name":"Pierre","full_name":"Mahou, Pierre","last_name":"Mahou"},{"first_name":"Mónika","full_name":"Hrtyan, Mónika","id":"45A71A74-F248-11E8-B48F-1D18A9856A87","last_name":"Hrtyan"},{"full_name":"Wang, Jie","first_name":"Jie","last_name":"Wang"},{"full_name":"Aguilera Servin, Juan L","first_name":"Juan L","last_name":"Aguilera Servin","id":"2A67C376-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2862-8372"},{"last_name":"van Damme","first_name":"Daniël","full_name":"van Damme, Daniël"},{"last_name":"Beaurepaire","full_name":"Beaurepaire, Emmanuel","first_name":"Emmanuel"},{"first_name":"Martin","full_name":"Loose, Martin","last_name":"Loose","id":"462D4284-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7309-9724"},{"full_name":"Bednarek, Sebastian Y","first_name":"Sebastian Y","last_name":"Bednarek"},{"full_name":"Friml, Jiří","first_name":"Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","orcid":"0000-0002-8302-7596"}],"month":"12","file_date_updated":"2021-12-15T08:59:40Z","abstract":[{"text":"Clathrin-mediated endocytosis is the major route of entry of cargos into cells and thus underpins many physiological processes. During endocytosis, an area of flat membrane is remodeled by proteins to create a spherical vesicle against intracellular forces. The protein machinery which mediates this membrane bending in plants is unknown. However, it is known that plant endocytosis is actin independent, thus indicating that plants utilize a unique mechanism to mediate membrane bending against high-turgor pressure compared to other model systems. Here, we investigate the TPLATE complex, a plant-specific endocytosis protein complex. It has been thought to function as a classical adaptor functioning underneath the clathrin coat. However, by using biochemical and advanced live microscopy approaches, we found that TPLATE is peripherally associated with clathrin-coated vesicles and localizes at the rim of endocytosis events. As this localization is more fitting to the protein machinery involved in membrane bending during endocytosis, we examined cells in which the TPLATE complex was disrupted and found that the clathrin structures present as flat patches. This suggests a requirement of the TPLATE complex for membrane bending during plant clathrin–mediated endocytosis. Next, we used in vitro biophysical assays to confirm that the TPLATE complex possesses protein domains with intrinsic membrane remodeling activity. These results redefine the role of the TPLATE complex and implicate it as a key component of the evolutionarily distinct plant endocytosis mechanism, which mediates endocytic membrane bending against the high-turgor pressure in plant cells.","lang":"eng"}],"isi":1,"fulldoi":"https://doi.org/10.1073/pnas.2113046118","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We gratefully thank Julie Neveu and Dr. Amanda Barranco of the Grégory Vert laboratory for help preparing plants in France, Dr. Zuzana Gelova for help and advice with protoplast generation, Dr. Stéphane Vassilopoulos and Dr. Florian Schur for advice regarding EM tomography, Alejandro Marquiegui Alvaro for help with material generation, and Dr. Lukasz Kowalski for generously gifting us the mWasabi protein.

To do this, we fabricate stacks composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic phonon polaritons (PhPs), and image the propagation of the latter when launched by localized sources. Our images reveal that, under a critical angle, the PhPs isofrequency curve undergoes a topological transition, in which the propagation of PhPs is strongly guided (canalization regime) along predetermined directions without geometric spreading. These results demonstrate a new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nanoimaging, (bio)-sensing, or heat management."}],"isi":1,"fulldoi":"https://doi.org/10.1021/acs.nanolett.0c01673","type":"journal_article","month":"07","author":[{"first_name":"Jiahua","full_name":"Duan, Jiahua","last_name":"Duan"},{"last_name":"Capote-Robayna","first_name":"Nathaniel","full_name":"Capote-Robayna, Nathaniel"},{"last_name":"Taboada-Gutiérrez","full_name":"Taboada-Gutiérrez, Javier","first_name":"Javier"},{"first_name":"Gonzalo","full_name":"Álvarez-Pérez, Gonzalo","last_name":"Álvarez-Pérez"},{"last_name":"Prieto Gonzalez","id":"2A307FE2-F248-11E8-B48F-1D18A9856A87","full_name":"Prieto Gonzalez, Ivan","first_name":"Ivan","orcid":"0000-0002-7370-5357"},{"first_name":"Javier","full_name":"Martín-Sánchez, Javier","last_name":"Martín-Sánchez"},{"full_name":"Nikitin, Alexey Y.","first_name":"Alexey Y.","last_name":"Nikitin"},{"last_name":"Alonso-González","first_name":"Pablo","full_name":"Alonso-González, Pablo"}],"issue":"7","article_type":"original","language":[{"iso":"eng"}],"external_id":{"isi":["000548893200082"],"pmid":["32530634"],"arxiv":["2004.14599"]},"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"pmid":1,"publication_status":"published","department":[{"_id":"NanoFab"}],"citation":{"ieee":"J.

However, the lack of tunability of their narrow and material-specific spectral range—the Reststrahlen band—severely limits their technological implementation. Here, we demonstrate that intercalation of Na atoms in the van der Waals semiconductor α-V2O5 enables a broad spectral shift of Reststrahlen bands, and that the phonon polaritons excited show ultra-low losses (lifetime of 4 ± 1 ps), similar to phonon polaritons in a non-intercalated crystal (lifetime of 6 ± 1 ps). We expect our intercalation method to be applicable to other van der Waals crystals, opening the door for the use of phonon polaritons in broad spectral bands in the mid-infrared domain."}],"isi":1,"doi":"10.1038/s41563-020-0665-0","article_processing_charge":"No","quality_controlled":"1","OA_type":"green","OA_place":"repository","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"J.T.-G. and G.Á.-P. acknowledge support through the Severo Ochoa Program from the Government of the Principality of Asturias (nos.

How a cell surveys and then corrects its own shape is poorly understood. Here, we demonstrate that spatially distinct microtubule dynamics regulate amoeboid cell migration by locally promoting the retraction of protrusions. In migrating dendritic cells, local microtubule depolymerization within protrusions remote from the microtubule organizing center triggers actomyosin contractility controlled by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin localization, thereby causing two effects that rate-limit locomotion: (1) impaired cell edge coordination during path finding and (2) defective adhesion resolution. Compromised shape control is particularly hindering in geometrically complex microenvironments, where it leads to entanglement and ultimately fragmentation of the cell body. We thus demonstrate that microtubules can act as a proprioceptive device: they sense cell shape and control actomyosin retraction to sustain cellular coherence."}],"isi":1,"fulldoi":"https://doi.org/10.1083/jcb.201907154","type":"journal_article","article_number":"e201907154","author":[{"full_name":"Kopf, Aglaja","first_name":"Aglaja","id":"31DAC7B6-F248-11E8-B48F-1D18A9856A87","last_name":"Kopf","orcid":"0000-0002-2187-6656"},{"first_name":"Jörg","full_name":"Renkawitz, Jörg","last_name":"Renkawitz","id":"3F0587C8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2856-3369"},{"orcid":"0000-0001-9843-3522","first_name":"Robert","full_name":"Hauschild, Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","last_name":"Hauschild"},{"last_name":"Girkontaite","first_name":"Irute","full_name":"Girkontaite, Irute"},{"full_name":"Tedford, Kerry","first_name":"Kerry","last_name":"Tedford"},{"full_name":"Merrin, Jack","first_name":"Jack","id":"4515C308-F248-11E8-B48F-1D18A9856A87","last_name":"Merrin","orcid":"0000-0001-5145-4609"},{"last_name":"Thorn-Seshold","full_name":"Thorn-Seshold, Oliver","first_name":"Oliver"},{"last_name":"Trauner","id":"E8F27F48-3EBA-11E9-92A1-B709E6697425","full_name":"Trauner, Dirk","first_name":"Dirk"},{"last_name":"Häcker","full_name":"Häcker, Hans","first_name":"Hans"},{"last_name":"Fischer","full_name":"Fischer, Klaus Dieter","first_name":"Klaus Dieter"},{"full_name":"Kiermaier, Eva","first_name":"Eva","last_name":"Kiermaier","id":"3EB04B78-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6165-5738"},{"id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","full_name":"Sixt, Michael K","first_name":"Michael K","orcid":"0000-0002-6620-9179"}],"month":"06","ec_funded":1,"publisher":"Rockefeller University Press","intvolume":"       219","date_published":"2020-06-01T00:00:00Z","title":"Microtubules control cellular shape and coherence in amoeboid migrating cells","scopus_import":"1","acknowledgement":"The authors thank the Scientific Service Units (Life Sciences, Bioimaging, Preclinical) of the Institute of Science and Technology Austria for excellent support.

While force coupling is usually mediated by transmembrane adhesion receptors, especially those of the integrin family, amoeboid cells such as leukocytes can migrate extremely fast despite very low adhesive forces1. Here we show that leukocytes cannot only migrate under low adhesion but can also transmit forces in the complete absence of transmembrane force coupling. When confined within three-dimensional environments, they use the topographical features of the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton follows the texture of the substrate, creating retrograde shear forces that are sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent migration are not mutually exclusive, but rather are variants of the same principle of coupling retrograde actin flow to the environment and thus can potentially operate interchangeably and simultaneously. As adhesion-free migration is independent of the chemical composition of the environment, it renders cells completely autonomous in their locomotive behaviour.","lang":"eng"}],"ec_funded":1,"author":[{"orcid":"0000-0003-0666-8928","id":"35B76592-F248-11E8-B48F-1D18A9856A87","last_name":"Reversat","first_name":"Anne","full_name":"Reversat, Anne"},{"orcid":"0000-0001-6120-3723","id":"397A88EE-F248-11E8-B48F-1D18A9856A87","last_name":"Gärtner","first_name":"Florian R","full_name":"Gärtner, Florian R"},{"orcid":"0000-0001-5145-4609","first_name":"Jack","full_name":"Merrin, Jack","last_name":"Merrin","id":"4515C308-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Julian A","full_name":"Stopp, Julian A","last_name":"Stopp","id":"489E3F00-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0003-1671-393X","last_name":"Tasciyan","id":"4323B49C-F248-11E8-B48F-1D18A9856A87","first_name":"Saren","full_name":"Tasciyan, Saren"},{"id":"2A67C376-F248-11E8-B48F-1D18A9856A87","last_name":"Aguilera Servin","first_name":"Juan L","full_name":"Aguilera Servin, Juan L","orcid":"0000-0002-2862-8372"},{"first_name":"Ingrid","full_name":"De Vries, Ingrid","id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","last_name":"De Vries"},{"first_name":"Robert","full_name":"Hauschild, Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","last_name":"Hauschild","orcid":"0000-0001-9843-3522"},{"orcid":"0000-0002-6625-3348","last_name":"Hons","id":"4167FE56-F248-11E8-B48F-1D18A9856A87","first_name":"Miroslav","full_name":"Hons, Miroslav"},{"last_name":"Piel","full_name":"Piel, Matthieu","first_name":"Matthieu"},{"full_name":"Callan-Jones, Andrew","first_name":"Andrew","last_name":"Callan-Jones"},{"first_name":"Raphael","full_name":"Voituriez, Raphael","last_name":"Voituriez"},{"full_name":"Sixt, Michael K","first_name":"Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","orcid":"0000-0002-6620-9179"}],"month":"06","related_material":{"link":[{"relation":"press_release","description":"News on IST Homepage","url":"https://ist.ac.at/en/news/off-road-mode-enables-mobile-cells-to-move-freely/"}],"record":[{"id":"12401","status":"public","relation":"dissertation_contains"},{"id":"14697","status":"public","relation":"dissertation_contains"}]},"page":"582–585","scopus_import":"1","title":"Cellular locomotion using environmental topography","date_published":"2020-06-25T00:00:00Z","intvolume":"       582","publisher":"Springer Nature","quality_controlled":"1","doi":"10.1038/s41586-020-2283-z","article_processing_charge":"No","OA_place":"repository","acknowledgement":"We thank A.

The structure is around key papers and model\r\norganisms. While courses gradually change over time, a focus remains on understanding how\r\nmicrofluidics has developed as well as what it can and cannot do for researchers. As a primary\r\nstarting point, we cover micro-fluid mechanics principles and microfabrication of devices. A variety\r\nof applications are discussed using model prokaryotic and eukaryotic organisms from the set\r\nof bacteria (Escherichia coli), trypanosomes (Trypanosoma brucei), yeast (Saccharomyces cerevisiae),\r\nslime molds (Physarum polycephalum), worms (Caenorhabditis elegans), flies (Drosophila melangoster),\r\nplants (Arabidopsis thaliana), and mouse immune cells (Mus musculus). Other engineering and\r\nbiochemical methods discussed include biomimetics, organ on a chip, inkjet, droplet microfluidics,\r\nbiotic games, and diagnostics. While we have not yet reached the end-all lab on a chip,\r\nmicrofluidics can still be used effectively for specific applications.","lang":"eng"}],"file_date_updated":"2020-07-14T12:47:54Z","isi":1}]
