text: Effective immune responses rely on the efficient migration of leukocytes.
Yet, how temperature regulates migration dynamics at the single-cell level has
remained poorly understood. Using zebrafish embryos and mouse tissue explants,
we found that temperature positively regulates leukocyte migration speed, exploration,
and arrival frequencies to wounds and lymph vessels. Complementary 2D and 3D cultures
revealed that this thermokinetic control of cell migration is conserved across
immune cell types, independently of the 3D tissue environment. By applying precise
(sub-)cellular temperature modulation, we identified a rapid and reversible thermo-response
that depends on myosin II activity. Small physiological increases in temperature
(1°C –2°C), as present during fever-like conditions, profoundly increased immune
responses by accelerating arrival times at lymphatic vessels and tissue wounds.
These findings identify myosin-II-dependent actomyosin contractility as a critical
mechanical structure regulating single-cell thermo-adaptability, with physiological
implications for tuning the speed of immune responses in vivo.

text: Nonadherent polarized cells have been observed to have a pearlike, elongated
shape. Using a minimal model that describes the cell cortex as a thin layer of
contractile active gel, we show that the anisotropy of active stresses, controlled
by cortical viscosity and filament ordering, can account for this morphology.
The predicted shapes can be determined from the flow pattern only; they prove
to be independent of the mechanism at the origin of the cortical flow, and are
only weakly sensitive to the cytoplasmic rheology. In the case of actin flows
resulting from a contractile instability, we propose a phase diagram of three-dimensional
cell shapes that encompasses nonpolarized spherical, elongated, as well as oblate
shapes, all of which have been observed in experiment.

text: During metazoan development, the temporal pattern of morphogen signaling is
critical for organizing cell fates in space and time. Yet, tools for temporally
controlling morphogen signaling within the embryo are still scarce. Here, we developed
a photoactivatable Nodal receptor to determine how the temporal pattern of Nodal
signaling affects cell fate specification during zebrafish gastrulation. By using
this receptor to manipulate the duration of Nodal signaling in vivo by light,
we show that extended Nodal signaling within the organizer promotes prechordal
plate specification and suppresses endoderm differentiation. Endoderm differentiation
is suppressed by extended Nodal signaling inducing expression of the transcriptional
repressor goosecoid (gsc) in prechordal plate progenitors, which in turn restrains
Nodal signaling from upregulating the endoderm differentiation gene sox17 within
these cells. Thus, optogenetic manipulation of Nodal signaling identifies a critical
role of Nodal signaling duration for organizer cell fate specification during
gastrulation.

text: Cell movement has essential functions in development, immunity, and cancer.
Various cell migration patterns have been reported, but no general rule has emerged
so far. Here, we show on the basis of experimental data in vitro and in vivo that
cell persistence, which quantifies the straightness of trajectories, is robustly
coupled to cell migration speed. We suggest that this universal coupling constitutes
a generic law of cell migration, which originates in the advection of polarity
cues by an actin cytoskeleton undergoing flows at the cellular scale. Our analysis
relies on a theoretical model that we validate by measuring the persistence of
cells upon modulation of actin flow speeds and upon optogenetic manipulation of
the binding of an actin regulator to actin filaments. Beyond the quantitative
prediction of the coupling, the model yields a generic phase diagram of cellular
trajectories, which recapitulates the full range of observed migration patterns.

text: 3D amoeboid cell migration is central to many developmental and disease-related
processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid
cell migration mode in early zebrafish embryos, termed stable-bleb migration.
Stable-bleb cells display an invariant polarized balloon-like shape with exceptional
migration speed and persistence. Progenitor cells can be reversibly transformed
into stable-bleb cells irrespective of their primary fate and motile characteristics
by increasing myosin II activity through biochemical or mechanical stimuli. Using
a combination of theory and experiments, we show that, in stable-bleb cells, cortical
contractility fluctuations trigger a stochastic switch into amoeboid motility,
and a positive feedback between cortical flows and gradients in contractility
maintains stable-bleb cell polarization. We further show that rearward cortical
flows drive stable-bleb cell migration in various adhesive and non-adhesive environments,
unraveling a highly versatile amoeboid migration phenotype.

text: In the past decade carbon nanotubes (CNTs) have been widely studied as a potential
drug-delivery system, especially with functionality for cellular targeting. Yet,
little is known about the actual process of docking to cell receptors and transport
dynamics after internalization. Here we performed single-particle studies of folic
acid (FA) mediated CNT binding to human carcinoma cells and their transport inside
the cytosol. In particular, we employed molecular recognition force spectroscopy,
an atomic force microscopy based method, to visualize and quantify docking of
FA functionalized CNTs to FA binding receptors in terms of binding probability
and binding force. We then traced individual fluorescently labeled, FA functionalized
CNTs after specific uptake, and created a dynamic 'roadmap' that clearly showed
trajectories of directed diffusion and areas of nanotube confinement in the cytosol.
Our results demonstrate the potential of a single-molecule approach for investigation
of drug-delivery vehicles and their targeting capacity.

text: Mechanically coupled cells can generate forces driving cell and tissue morphogenesis
during development. Visualization and measuring of these forces is of major importance
to better understand the complexity of the biomechanic processes that shape cells
and tissues. Here, we describe how UV laser ablation can be utilized to quantitatively
assess mechanical tension in different tissues of the developing zebrafish and
in cultures of primary germ layer progenitor cells ex vivo.

text: Resolving the dynamical interplay of proteins and lipids in the live-cell
plasma membrane represents a central goal in current cell biology. Superresolution
concepts have introduced a means of capturing spatial heterogeneity at a nanoscopic
length scale. Similar concepts for detecting dynamical transitions (superresolution
chronoscopy) are still lacking. Here, we show that recently introduced spot-variation
fluorescence correlation spectroscopy allows for sensing transient confinement
times of membrane constituents at dramatically improved resolution. Using standard
diffraction-limited optics, spot-variation fluorescence correlation spectroscopy
captures signatures of single retardation events far below the transit time of
the tracer through the focal spot. We provide an analytical description of special
cases of transient binding of a tracer to pointlike traps, or association of a
tracer with nanodomains. The influence of trap mobility and the underlying binding
kinetics are quantified. Experimental approaches are suggested that allow for
gaining quantitative mechanistic insights into the interaction processes of membrane
constituents.

text: Cationic antimicrobial peptides (CAMPs) selectively target bacterial membranes
by electrostatic interactions with negatively charged lipids. It turned out that
for inhibition of microbial growth a high CAMP membrane concentration is required,
which can be realized by the incorporation of hydrophobic groups within the peptide.
Increasing hydrophobicity, however, reduces the CAMP selectivity for bacterial
over eukaryotic host membranes, thereby causing the risk of detrimental side-effects.
In this study we addressed how cationic amphipathic peptides—in particular a CAMP
with Lysine–Leucine–Lysine repeats (termed KLK)—affect the localization and dynamics
of molecules in eukaryotic membranes. We found KLK to selectively inhibit the
endocytosis of a subgroup of membrane proteins and lipids by electrostatically
interacting with negatively charged sialic acid moieties. Ultrastructural characterization
revealed the formation of membrane invaginations representing fission or fusion
intermediates, in which the sialylated proteins and lipids were immobilized. Experiments
on structurally different cationic amphipathic peptides (KLK, 6-MO-LF11-322 and
NK14-2) indicated a cooperation of electrostatic and hydrophobic forces that selectively
arrest sialylated membrane constituents.

text: 'Diffusing membrane constituents are constantly exposed to a variety of forces
that influence their stochastic path. Single molecule experiments allow for resolving
trajectories at extremely high spatial and temporal accuracy, thereby offering
insights into en route interactions of the tracer. In this review we discuss approaches
to derive information about the underlying processes, based on single molecule
tracking experiments. In particular, we focus on a new versatile way to analyze
single molecule diffusion in the absence of a full analytical treatment. The method
is based on comprehensive comparison of an experimental data set against the hypothetical
outcome of multiple experiments performed on the computer. Since Monte Carlo simulations
can be easily and rapidly performed even on state-of-the-art PCs, our method provides
a simple way for testing various - even complicated - diffusion models. We describe
the new method in detail, and show the applicability on two specific examples:
firstly, kinetic rate constants can be derived for the transient interaction of
mobile membrane proteins; secondly, residence time and corral size can be extracted
for confined diffusion.'
