  text: "The brain is an exceptionally sophisticated organ consisting of billions
    of cells and trillions of \r\nconnections that orchestrate our cognition and behavior.
    To decode its complex connectivity, it is \r\npivotal to disentangle its intricate
    architecture spanning from cm-sized circuits down to tens of \r\nnm-small synapses.\r\nTo
    achieve this goal, I developed CATS – Comprehensive Analysis of nervous Tissue
    across \r\nScales, a versatile toolbox for obtaining a holistic view of nervous
    tissue context with (super\x02resolution) fluorescence microscopy. CATS combines
    comprehensive labeling of the extracellular\r\nspace, that is compatible with
    chemical fixation, with information on molecular markers, super\x02resolved data
    acquisition and machine-learning based data analysis for segmentation and synapse
    \r\nidentification.\r\nI used CATS to analyze key features of nervous tissue connectivity,
    ranging from whole tissue \r\narchitecture, neuronal in- and output-fields, down
    to synapse morphology.\r\nFocusing on the hippocampal circuitry, I quantified
    synaptic transmission properties of mossy \r\nfiber boutons and analyzed the connectivity
    pattern of dentate gyrus granule cells with CA3 \r\npyramidal neurons. This shows
    that CATS is a viable tool to study hallmarks of neuronal \r\nconnectivity with
    light microscopy."

  text: Statistics of natural scenes are not uniform - their structure varies dramatically
    from ground to sky. It remains unknown whether these non-uniformities are reflected
    in the large-scale organization of the early visual system and what benefits such
    adaptations would confer. Here, by relying on the efficient coding hypothesis,
    we predict that changes in the structure of receptive fields across visual space
    increase the efficiency of sensory coding. We show experimentally that, in agreement
    with our predictions, receptive fields of retinal ganglion cells change their
    shape along the dorsoventral retinal axis, with a marked surround asymmetry at
    the visual horizon. Our work demonstrates that, according to principles of efficient
    coding, the panoramic structure of natural scenes is exploited by the retina across
    space and cell-types.

- lang: eng
  text: 'The emergence of large-scale order in self-organized systems relies on local
    interactions between individual components. During bacterial cell division, FtsZ
    -- a prokaryotic homologue of the eukaryotic protein tubulin -- polymerizes into
    treadmilling filaments that further organize into a cytoskeletal ring. In vitro,
    FtsZ filaments can form dynamic chiral assemblies. However, how the active and
    passive properties of individual filaments relate to these large-scale self-organized
    structures remains poorly understood. Here, we connect single filament properties
    with the mesoscopic scale by combining minimal active matter simulations and biochemical
    reconstitution experiments. We show that density and flexibility of active chiral
    filaments define their global order. At intermediate densities, curved, flexible
    filaments organize into chiral rings and polar bands. An effectively nematic organization
    dominates for high densities and for straight, mutant filaments with increased
    rigidity. Our predicted phase diagram captures these features quantitatively,
    demonstrating how the flexibility, density and chirality of active filaments affect
    their collective behaviour. Our findings shed light on the fundamental properties
    of active chiral matter and explain how treadmilling FtsZ filaments organize during
    bacterial cell division. '

  text: The emergence of large-scale order in self-organized systems relies on local
    interactions between individual components. During bacterial cell division, FtsZ—a
    prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling
    filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments
    can form dynamic chiral assemblies. However, how the active and passive properties
    of individual filaments relate to these large-scale self-organized structures
    remains poorly understood. Here we connect single-filament properties with the
    mesoscopic scale by combining minimal active matter simulations and biochemical
    reconstitution experiments. We show that the density and flexibility of active
    chiral filaments define their global order. At intermediate densities, curved,
    flexible filaments organize into chiral rings and polar bands. An effectively
    nematic organization dominates for high densities and for straight, mutant filaments
    with increased rigidity. Our predicted phase diagram quantitatively captures these
    features, demonstrating how the flexibility, density and chirality of the active
    filaments affect their collective behaviour. Our findings shed light on the fundamental
    properties of active chiral matter and explain how treadmilling FtsZ filaments
    organize during bacterial cell division.

  text: Auxin is the major plant hormone regulating growth and development (Friml,
    2022). Forward genetic approaches in the model plant Arabidopsis thaliana have
    identified major components of auxin signalling and established the canonical
    mechanism mediating transcriptional and thus developmental reprogramming. In this
    textbook view, TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOX (AFBs)
    are auxin receptors, which act as F-box subunits determining the substrate specificity
    of the Skp1-Cullin1-F box protein (SCF) type E3 ubiquitin ligase complex. Auxin
    acts as a “molecular glue” increasing the affinity between TIR1/AFBs and the Aux/IAA
    repressors. Subsequently, Aux/IAAs are ubiquitinated and degraded, thus releasing
    auxin transcription factors from their repression making them free to mediate
    transcription of auxin response genes (Yu et al., 2022). Nonetheless, accumulating
    evidence suggests existence of rapid, non-transcriptional responses downstream
    of TIR1/AFBs such as auxin-induced cytosolic calcium (Ca2+) transients, plasma
    membrane depolarization and apoplast alkalinisation, all converging on the process
    of root growth inhibition and root gravitropism (Li et al., 2022). Particularly,
    these rapid responses are mostly contributed by predominantly cytosolic AFB1,
    while the long-term growth responses are mediated by mainly nuclear TIR1 and AFB2-AFB5
    (Li et al., 2021; Prigge et al., 2020; Serre et al., 2021). How AFB1 conducts
    auxin-triggered rapid responses and how it is different from TIR1 and AFB2-AFB5
    remains elusive. Here, we compare the roles of TIR1 and AFB1 in transcriptional
    and rapid responses by modulating their subcellular localization in Arabidopsis
    and by testing their ability to mediate transcriptional responses when part of
    the minimal auxin circuit reconstituted in yeast.

  text: Animals that lose one sensory modality often show augmented responses to other
    sensory inputs. The mechanisms underpinning this cross-modal plasticity are poorly
    understood. We probe such mechanisms by performing a forward genetic screen for
    mutants with enhanced O2 perception in Caenorhabditis elegans. Multiple mutants
    exhibiting increased O2 responsiveness concomitantly show defects in other sensory
    responses. One mutant, qui-1, defective in a conserved NACHT/WD40 protein, abolishes
    pheromone-evoked Ca2+ responses in the ADL pheromone-sensing neurons. At the same
    time, ADL responsiveness to pre-synaptic input from O2-sensing neurons is heightened
    in qui-1, and other sensory defective mutants, resulting in enhanced neurosecretion
    although not increased Ca2+ responses. Expressing qui-1 selectively in ADL rescues
    both the qui-1 ADL neurosecretory phenotype and enhanced escape from 21% O2. Profiling
    ADL neurons in qui-1 mutants highlights extensive changes in gene expression,
    notably of many neuropeptide receptors. We show that elevated ADL expression of
    the conserved neuropeptide receptor NPR-22 is necessary for enhanced ADL neurosecretion
    in qui-1 mutants, and is sufficient to confer increased ADL neurosecretion in
    control animals. Sensory loss can thus confer cross-modal plasticity by changing
    the peptidergic connectome.

  text: Cellular metabolism must adapt to changing demands to enable homeostasis.
    During immune responses or cancer metastasis, cells leading migration into challenging
    environments require an energy boost, but what controls this capacity is unclear.
    Here, we study a previously uncharacterized nuclear protein, Atossa (encoded by
    CG9005), which supports macrophage invasion into the germband of Drosophila by
    controlling cellular metabolism. First, nuclear Atossa increases mRNA levels of
    Porthos, a DEAD-box protein, and of two metabolic enzymes, lysine-α-ketoglutarate
    reductase (LKR/SDH) and NADPH glyoxylate reductase (GR/HPR), thus enhancing mitochondrial
    bioenergetics. Then Porthos supports ribosome assembly and thereby raises the
    translational efficiency of a subset of mRNAs, including those affecting mitochondrial
    functions, the electron transport chain, and metabolism. Mitochondrial respiration
    measurements, metabolomics, and live imaging indicate that Atossa and Porthos
    power up OxPhos and energy production to promote the forging of a path into tissues
    by leading macrophages. Since many crucial physiological responses require increases
    in mitochondrial energy output, this previously undescribed genetic program may
    modulate a wide range of cellular behaviors.

  text: "Although we often see studies focusing on simple or even discrete traits
    in studies of colouration,\r\nthe variation of “appearance” phenotypes found in
    nature is often more complex, continuous\r\nand high-dimensional. Therefore, we
    developed automated methods suitable for large datasets\r\nof genomes and images,
    striving to account for their complex nature, while minimising human\r\nbias.
    We used these methods on a dataset of more than 20, 000 plant SNP genomes and\r\ncorresponding
    fower images from a hybrid zone of two subspecies of Antirrhinum majus with\r\ndistinctly
    coloured fowers to improve our understanding of the genetic nature of the fower\r\ncolour
    in our study system.\r\nFirstly, we use the advantage of large numbers of genotyped
    plants to estimate the haplotypes in\r\nthe main fower colour regulating region.
    We study colour- and geography-related characteristics\r\nof the estimated haplotypes
    and how they connect to their relatedness. We show discrepancies\r\nfrom the expected
    fower colour distributions given the genotype and identify particular\r\nhaplotypes
    leading to unexpected phenotypes. We also confrm a signifcant defcit of the\r\ndouble
    recessive recombinant and quite surprisingly, we show that haplotypes of the most\r\nfrequent
    parental type are much less variable than others.\r\nSecondly, we introduce our
    pipeline capable of processing tens of thousands of full fower\r\nimages without
    human interaction and summarising each image into a set of informative scores.\r\nWe
    show the compatibility of these machine-measured fower colour scores with the
    previously\r\nused manual scores and study impact of external efect on the resulting
    scores. Finally, we use\r\nthe machine-measured fower colour scores to ft and
    examine a phenotype cline across the\r\nhybrid zone in Planoles using full fower
    images as opposed to discrete, manual scores and\r\ncompare it with the genotypic
    cline."

  text: The generation of a correctly-sized cerebral cortex with all-embracing neuronal
    and glial cell-type diversity critically depends on faithful radial glial progenitor
    (RGP) cell proliferation/differentiation programs. Temporal RGP lineage progression
    is regulated by Polycomb Repressive Complex 2 (PRC2) and loss of PRC2 activity
    results in severe neurogenesis defects and microcephaly. How PRC2-dependent gene
    expression instructs RGP lineage progression is unknown. Here we utilize Mosaic
    Analysis with Double Markers (MADM)-based single cell technology and demonstrate
    that PRC2 is not cell-autonomously required in neurogenic RGPs but rather acts
    at the global tissue-wide level. Conversely, cortical astrocyte production and
    maturation is cell-autonomously controlled by PRC2-dependent transcriptional regulation.
    We thus reveal highly distinct and sequential PRC2 functions in RGP lineage progression
    that are dependent on complex interplays between intrinsic and tissue-wide properties.
    In a broader context our results imply a critical role for the genetic and cellular
    niche environment in neural stem cell behavior.

  text: Intragenic regions that are removed during maturation of the RNA transcript—introns—are
    universally present in the nuclear genomes of eukaryotes1. The budding yeast,
    an otherwise intron-poor species, preserves two sets of ribosomal protein genes
    that differ primarily in their introns2,3. Although studies have shed light on
    the role of ribosomal protein introns under stress and starvation4,5,6, understanding
    the contribution of introns to ribosome regulation remains challenging. Here,
    by combining isogrowth profiling7 with single-cell protein measurements8, we show
    that introns can mediate inducible phenotypic heterogeneity that confers a clear
    fitness advantage. Osmotic stress leads to bimodal expression of the small ribosomal
    subunit protein Rps22B, which is mediated by an intron in the 5′ untranslated
    region of its transcript. The two resulting yeast subpopulations differ in their
    ability to cope with starvation. Low levels of Rps22B protein result in prolonged
    survival under sustained starvation, whereas high levels of Rps22B enable cells
    to grow faster after transient starvation. Furthermore, yeasts growing at high
    concentrations of sugar, similar to those in ripe grapes, exhibit bimodal expression
    of Rps22B when approaching the stationary phase. Differential intron-mediated
    regulation of ribosomal protein genes thus provides a way to diversify the population
    when starvation threatens in natural environments. Our findings reveal a role
    for introns in inducing phenotypic heterogeneity in changing environments, and
    suggest that duplicated ribosomal protein genes in yeast contribute to resolving
    the evolutionary conflict between precise expression control and environmental
    responsiveness9.

  text: Mineral nutrition is one of the key environmental factors determining plant
    development and growth. Nitrate is the major form of macronutrient nitrogen that
    plants take up from the soil. Fluctuating availability or deficiency of this element
    severely limits plant growth and negatively affects crop production in the agricultural
    system. To cope with the heterogeneity of nitrate distribution in soil, plants
    evolved a complex regulatory mechanism that allows rapid adjustment of physiological
    and developmental processes to the status of this nutrient. The root, as a major
    exploitation organ that controls the uptake of nitrate to the plant body, acts
    as a regulatory hub that, according to nitrate availability, coordinates the growth
    and development of other plant organs. Here, we identified a regulatory framework,
    where cytokinin response factors (CRFs) play a central role as a molecular readout
    of the nitrate status in roots to guide shoot adaptive developmental response.
    We show that nitrate-driven activation of NLP7, a master regulator of nitrate
    response in plants, fine tunes biosynthesis of cytokinin in roots and its translocation
    to shoots where it enhances expression of CRFs. CRFs, through direct transcriptional
    regulation of PIN auxin transporters, promote the flow of auxin and thereby stimulate
    the development of shoot organs.

  text: "G protein-coupled receptors (GPCRs) respond to specific ligands and regulate
    multiple processes ranging from cell growth and immune responses to neuronal signal
    transmission. However, ligands for many GPCRs remain unknown, suffer from off-target
    effects or have poor bioavailability. Additional challenges exist to dissect cell-type
    specific responses when the same GPCR is expressed on several cell types within
    the body. Here, we overcome these limitations by engineering DREADD-based GPCR
    chimeras that selectively bind their agonist clozapine-N-oxide (CNO) and mimic
    a GPCR-of-interest in a desired cell type.\r\nWe validated our approach with β2-adrenergic
    receptor (β2AR/ADRB2) and show that our chimeric DREADD-β2AR triggers comparable
    responses on second messenger and kinase activity, post-translational modifications,
    and protein-protein interactions. Since β2AR is also enriched in microglia, which
    can drive inflammation in the central nervous system, we expressed chimeric DREADD-β2AR
    in primary microglia and successfully recapitulate β2AR-mediated filopodia formation
    through CNO stimulation. To dissect the role of selected GPCRs during microglial
    inflammation, we additionally generated DREADD-based chimeras for microglia-enriched
    GPR65 and GPR109A/HCAR2. In a microglia cell line, DREADD-β2AR and DREADD-GPR65
    both modulated the inflammatory response with a similar profile as endogenously
    expressed β2AR, while DREADD-GPR109A showed no impact.\r\nOur DREADD-based approach
    provides the means to obtain mechanistic and functional insights into GPCR signaling
    on a cell-type specific level."

abstract:
- lang: eng
  text: The mammalian hippocampal formation (HF) plays a key role in several higher
    brain functions, such as spatial coding, learning and memory. Its simple circuit
    architecture is often viewed as a trisynaptic loop, processing input originating
    from the superficial layers of the entorhinal cortex (EC) and sending it back
    to its deeper layers. Here, we show that excitatory neurons in layer 6b of the
    mouse EC project to all sub-regions comprising the HF and receive input from the
    CA1, thalamus and claustrum. Furthermore, their output is characterized by unique
    slow-decaying excitatory postsynaptic currents capable of driving plateau-like
    potentials in their postsynaptic targets. Optogenetic inhibition of the EC-6b
    pathway affects spatial coding in CA1 pyramidal neurons, while cell ablation impairs
    not only acquisition of new spatial memories, but also degradation of previously
    acquired ones. Our results provide evidence of a functional role for cortical
    layer 6b neurons in the adult brain.

  text: Proximity-dependent protein labeling provides a powerful in vivo strategy
    to characterize the interactomes of specific proteins. We previously optimized
    a proximity labeling protocol for Caenorhabditis elegans using the highly active
    biotin ligase TurboID. A significant constraint on the sensitivity of TurboID
    is the presence of abundant endogenously biotinylated proteins that take up bandwidth
    in the mass spectrometer, notably carboxylases that use biotin as a cofactor.
    In C. elegans, these comprise POD-2/acetyl-CoA carboxylase alpha, PCCA-1/propionyl-CoA
    carboxylase alpha, PYC-1/pyruvate carboxylase, and MCCC-1/methylcrotonyl-CoA carboxylase
    alpha. Here, we developed ways to remove these carboxylases prior to streptavidin
    purification and mass spectrometry by engineering their corresponding genes to
    add a C-terminal His10 tag. This allows us to deplete them from C. elegans lysates
    using immobilized metal affinity chromatography. To demonstrate the method's efficacy,
    we use it to expand the interactome map of the presynaptic active zone protein
    ELKS-1. We identify many known active zone proteins, including UNC-10/RIM, SYD-2/liprin-alpha,
    SAD-1/BRSK1, CLA-1/CLArinet, C16E9.2/Sentryn, as well as previously uncharacterized
    potentially synaptic proteins such as the ortholog of human angiomotin, F59C12.3
    and the uncharacterized protein R148.3. Our approach provides a quick and inexpensive
    solution to a common contaminant problem in biotin-dependent proximity labeling.
    The approach may be applicable to other model organisms and will enable deeper
    and more complete analysis of interactors for proteins of interest.

  text: "To understand how potential gene manipulations affect in vitro microglia,
    we provide a set of short protocols to evaluate microglia identity and function.
    We detail steps for immunostaining to determine microglia identity. We describe
    three functional assays for microglia: phagocytosis, calcium response following
    ATP stimulation, and cytokine expression upon inflammatory stimuli. We apply these
    protocols to human induced-pluripotent-stem-cell (hiPSC)-derived microglia, but
    they can be also applied to other in vitro microglial models including primary
    mouse microglia.\r\nFor complete details on the use and execution of this protocol,

  text: The phytohormone auxin is the major coordinative signal in plant development1,
    mediating transcriptional reprogramming by a well-established canonical signalling
    pathway. TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOX (AFB) auxin
    receptors are F-box subunits of ubiquitin ligase complexes. In response to auxin,
    they associate with Aux/IAA transcriptional repressors and target them for degradation
    via ubiquitination2,3. Here we identify adenylate cyclase (AC) activity as an
    additional function of TIR1/AFB receptors across land plants. Auxin, together
    with Aux/IAAs, stimulates cAMP production. Three separate mutations in the AC
    motif of the TIR1 C-terminal region, all of which abolish the AC activity, each
    render TIR1 ineffective in mediating gravitropism and sustained auxin-induced
    root growth inhibition, and also affect auxin-induced transcriptional regulation.
    These results highlight the importance of TIR1/AFB AC activity in canonical auxin
    signalling. They also identify a unique phytohormone receptor cassette combining
    F-box and AC motifs, and the role of cAMP as a second messenger in plants.

  text: Embryo development requires biochemical signalling to generate patterns of
    cell fates and active mechanical forces to drive tissue shape changes. However,
    how these processes are coordinated, and how tissue patterning is preserved despite
    the cellular flows occurring during morphogenesis, remains poorly understood.
    Gastrulation is a crucial embryonic stage that involves both patterning and internalization
    of the mesendoderm germ layer tissue. Here we show that, in zebrafish embryos,
    a gradient in Nodal signalling orchestrates pattern-preserving internalization
    movements by triggering a motility-driven unjamming transition. In addition to
    its role as a morphogen determining embryo patterning, graded Nodal signalling
    mechanically subdivides the mesendoderm into a small fraction of highly protrusive
    leader cells, able to autonomously internalize via local unjamming, and less protrusive
    followers, which need to be pulled inwards by the leaders. The Nodal gradient
    further enforces a code of preferential adhesion coupling leaders to their immediate
    followers, resulting in a collective and ordered mode of internalization that
    preserves mesendoderm patterning. Integrating this dual mechanical role of Nodal
    signalling into minimal active particle simulations quantitatively predicts both
    physiological and experimentally perturbed internalization movements. This provides
    a quantitative framework for how a morphogen-encoded unjamming transition can
    bidirectionally couple tissue mechanics with patterning during complex three-dimensional
    morphogenesis.

  text: Biological systems are the sum of their dynamic three-dimensional (3D) parts.
    Therefore, it is critical to study biological structures in 3D and at high resolution
    to gain insights into their physiological functions. Electron microscopy of metal
    replicas of unroofed cells and isolated organelles has been a key technique to
    visualize intracellular structures at nanometer resolution. However, many of these
    methods require specialized equipment and personnel to complete them. Here, we
    present novel accessible methods to analyze biological structures in unroofed
    cells and biochemically isolated organelles in 3D and at nanometer resolution,
    focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential
    trafficking organelles, their detailed structural information is lacking due to
    their poor preservation when observed via classical electron microscopy protocols
    experiments. First, we establish a method to visualize CCVs in unroofed cells
    using scanning transmission electron microscopy tomography, providing sufficient
    resolution to define the clathrin coat arrangements. Critically, the samples are
    prepared directly on electron microscopy grids, removing the requirement to use
    extremely corrosive acids, thereby enabling the use of this method in any electron
    microscopy lab. Secondly, we demonstrate that this standardized sample preparation
    allows the direct comparison of isolated CCV samples with those visualized in
    cells. Finally, to facilitate the high-throughput and robust screening of metal
    replicated samples, we provide a deep learning analysis method to screen the “pseudo
    3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes
    accessible ways to examine the 3D structure of biological samples and provide
    novel insights into the structure of plant CCVs.
