  text: Most migrating cells extrude their front by the force of actin polymerization.
    Polymerization requires an initial nucleation step, which is mediated by factors
    establishing either parallel filaments in the case of filopodia or branched filaments
    that form the branched lamellipodial network. Branches are considered essential
    for regular cell motility and are initiated by the Arp2/3 complex, which in turn
    is activated by nucleation-promoting factors of the WASP and WAVE families. Here
    we employed rapid amoeboid crawling leukocytes and found that deletion of the
    WAVE complex eliminated actin branching and thus lamellipodia formation. The cells
    were left with parallel filaments at the leading edge, which translated, depending
    on the differentiation status of the cell, into a unipolar pointed cell shape
    or cells with multiple filopodia. Remarkably, unipolar cells migrated with increased
    speed and enormous directional persistence, while they were unable to turn towards
    chemotactic gradients. Cells with multiple filopodia retained chemotactic activity
    but their migration was progressively impaired with increasing geometrical complexity
    of the extracellular environment. These findings establish that diversified leading
    edge protrusions serve as explorative structures while they slow down actual locomotion.

  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: 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: 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: 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: 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.'
