  text: The polymerization–depolymerization dynamics of cytoskeletal proteins play
    essential roles in the self-organization of cytoskeletal structures, in eukaryotic
    as well as prokaryotic cells. While advances in fluorescence microscopy and in
    vitro reconstitution experiments have helped to study the dynamic properties of
    these complex systems, methods that allow to collect and analyze large quantitative
    datasets of the underlying polymer dynamics are still missing. Here, we present
    a novel image analysis workflow to study polymerization dynamics of active filaments
    in a nonbiased, highly automated manner. Using treadmilling filaments of the bacterial
    tubulin FtsZ as an example, we demonstrate that our method is able to specifically
    detect, track and analyze growth and shrinkage of polymers, even in dense networks
    of filaments. We believe that this automated method can facilitate the analysis
    of a large variety of dynamic cytoskeletal systems, using standard time-lapse
    movies obtained from experiments in vitro as well as in the living cell. Moreover,
    we provide scripts implementing this method as supplementary material.

  text: The eukaryotic endomembrane system is controlled by small GTPases of the Rab
    family, which are activated at defined times and locations in a switch-like manner.
    While this switch is well understood for an individual protein, how regulatory
    networks produce intracellular activity patterns is currently not known. Here,
    we combine in vitro reconstitution experiments with computational modeling to
    study a minimal Rab5 activation network. We find that the molecular interactions
    in this system give rise to a positive feedback and bistable collective switching
    of Rab5. Furthermore, we find that switching near the critical point is intrinsically
    stochastic and provide evidence that controlling the inactive population of Rab5
    on the membrane can shape the network response. Notably, we demonstrate that collective
    switching can spread on the membrane surface as a traveling wave of Rab5 activation.
    Together, our findings reveal how biochemical signaling networks control vesicle
    trafficking pathways and how their nonequilibrium properties define the spatiotemporal
    organization of the cell.

  text: Wood, as the most abundant carbon dioxide storing bioresource, is currently
    driven beyond its traditional use through creative innovations and nanotechnology.
    For many properties the micro- and nanostructure plays a crucial role and one
    key challenge is control and detection of chemical and physical processes in the
    confined microstructure and nanopores of the wooden cell wall. In this study,
    correlative Raman and atomic force microscopy show high potential for tracking
    in situ molecular rearrangement of wood polymers during compression. More water
    molecules (interpreted as wider cellulose microfibril distances) and disentangling
    of hemicellulose chains are detected in the opened cell wall regions, whereas
    an increase of lignin is revealed in the compressed areas. These results support
    a new more “loose” cell wall model based on flexible lignin nanodomains and advance
    our knowledge of the molecular reorganization during deformation of wood for optimized
    processing and utilization.

  text: The assembly of a septin filament requires that homologous monomers must distinguish
    between one another in establishing appropriate interfaces with their neighbors.
    To understand this phenomenon at the molecular level, we present the first four
    crystal structures of heterodimeric septin complexes. We describe in detail the
    two distinct types of G-interface present within the octameric particles, which
    must polymerize to form filaments. These are formed between SEPT2 and SEPT6 and
    between SEPT7 and SEPT3, and their description permits an understanding of the
    structural basis for the selectivity necessary for correct filament assembly.
    By replacing SEPT6 by SEPT8 or SEPT11, it is possible to rationalize Kinoshita's
    postulate, which predicts the exchangeability of septins from within a subgroup.
    Switches I and II, which in classical small GTPases provide a mechanism for nucleotide-dependent
    conformational change, have been repurposed in septins to play a fundamental role
    in molecular recognition. Specifically, it is switch I which holds the key to
    discriminating between the two different G-interfaces. Moreover, residues which
    are characteristic for a given subgroup play subtle, but pivotal, roles in guaranteeing
    that the correct interfaces are formed.

  text: Numerous biophysical questions require the quantification of short-range interactions
    between (functionalized) surfaces and synthetic or biological objects such as
    cells. Here, we present an original, custom built setup for reflection interference
    contrast microscopy that can assess distances between a substrate and a flowing
    object at high speed with nanometric accuracy. We demonstrate its use to decipher
    the complex biochemical and mechanical interplay regulating blood cell homing
    at the vessel wall in the microcirculation using an in vitro approach. We show
    that in the absence of specific biochemical interactions, flowing cells are repelled
    from the soft layer lining the vessel wall, contributing to red blood cell repulsion
    in vivo. In contrast, this so-called glycocalyx stabilizes rolling of cells under
    flow in the presence of a specific receptor naturally present on activated leucocytes
    and a number of cancer cell lines.

  text: During bacterial cell division, the tubulin-homolog FtsZ forms a ring-like
    structure at the center of the cell. This Z-ring not only organizes the division
    machinery, but treadmilling of FtsZ filaments was also found to play a key role
    in distributing proteins at the division site. What regulates the architecture,
    dynamics and stability of the Z-ring is currently unknown, but FtsZ-associated
    proteins are known to play an important role. Here, using an in vitro reconstitution
    approach, we studied how the well-conserved protein ZapA affects FtsZ treadmilling
    and filament organization into large-scale patterns. Using high-resolution fluorescence
    microscopy and quantitative image analysis, we found that ZapA cooperatively increases
    the spatial order of the filament network, but binds only transiently to FtsZ
    filaments and has no effect on filament length and treadmilling velocity. Together,
    our data provides a model for how FtsZ-associated proteins can increase the precision
    and stability of the bacterial cell division machinery in a switch-like manner.

  text: Cell-cell and cell-glycocalyx interactions under flow are important for the
    behaviour of circulating cells in blood and lymphatic vessels. However, such interactions
    are not well understood due in part to a lack of tools to study them in defined
    environments. Here, we develop a versatile in vitro platform for the study of
    cell-glycocalyx interactions in well-defined physical and chemical settings under
    flow. Our approach is demonstrated with the interaction between hyaluronan (HA,
    a key component of the endothelial glycocalyx) and its cell receptor CD44. We
    generate HA brushes in situ within a microfluidic device, and demonstrate the
    tuning of their physical (thickness and softness) and chemical (density of CD44
    binding sites) properties using characterisation with reflection interference
    contrast microscopy (RICM) and application of polymer theory. We highlight the
    interactions of HA brushes with CD44-displaying beads and cells under flow. Observations
    of CD44+ beads on a HA brush with RICM enabled the 3-dimensional trajectories
    to be generated, and revealed interactions in the form of stop and go phases with
    reduced rolling velocity and reduced distance between the bead and the HA brush,
    compared to uncoated beads. Combined RICM and bright-field microscopy of CD44+
    AKR1 T-lymphocytes revealed complementary information about the dynamics of cell
    rolling and cell morphology, and highlighted the formation of tethers and slings,
    as they interacted with a HA brush under flow. This platform can readily incorporate
    more complex models of the glycocalyx, and should permit the study of how mechanical
    and biochemical factors are orchestrated to enable highly selective blood cell-vessel
    wall interactions under flow.

  text: Conventional wisdom has it that proteins fold and assemble into definite structures,
    and that this defines their function. Glycosaminoglycans (GAGs) are different.
    In most cases the structures they form have a low degree of order, even when interacting
    with proteins. Here, we discuss how physical features common to all GAGs — hydrophilicity,
    charge, linearity and semi-flexibility — underpin the overall properties of GAG-rich
    matrices. By integrating soft matter physics concepts (e.g. polymer brushes and
    phase separation) with our molecular understanding of GAG–protein interactions,
    we can better comprehend how GAG-rich matrices assemble, what their properties
    are, and how they function. Taking perineuronal nets (PNNs) — a GAG-rich matrix
    enveloping neurons — as a relevant example, we propose that microphase separation
    determines the holey PNN anatomy that is pivotal to PNN functions.

  text: Inflammation, which is a highly regulated host response against danger signals,
    may be harmful if it is excessive and deregulated. Ideally, anti-inflammatory
    therapy should autonomously commence as soon as possible after the onset of inflammation,
    should be controllable by a physician, and should not systemically block beneficial
    immune response in the long term. We describe a genetically encoded anti-inflammatory
    mammalian cell device based on a modular engineered genetic circuit comprising
    a sensor, an amplifier, a “thresholder” to restrict activation of a positive-feedback
    loop, a combination of advanced clinically used biopharmaceutical proteins, and
    orthogonal regulatory elements that linked modules into the functional device.
    This genetic circuit was autonomously activated by inflammatory signals, including
    endogenous cecal ligation and puncture (CLP)-induced inflammation in mice and
    serum from a systemic juvenile idiopathic arthritis (sIJA) patient, and could
    be reset externally by a chemical signal. The microencapsulated anti-inflammatory
    device significantly reduced the pathology in dextran sodium sulfate (DSS)-induced
    acute murine colitis, demonstrating a synthetic immunological approach for autonomous
    anti-inflammatory therapy.

  text: Even simple cells like bacteria have precisely regulated cellular anatomies,
    which allow them to grow, divide and to respond to internal or external cues with
    high fidelity. How spatial and temporal intracellular organization in prokaryotic
    cells is achieved and maintained on the basis of locally interacting proteins
    still remains largely a mystery. Bulk biochemical assays with purified components
    and in vivo experiments help us to approach key cellular processes from two opposite
    ends, in terms of minimal and maximal complexity. However, to understand how cellular
    phenomena emerge, that are more than the sum of their parts, we have to assemble
    cellular subsystems step by step from the bottom up. Here, we review recent in
    vitro reconstitution experiments with proteins of the bacterial cell division
    machinery and illustrate how they help to shed light on fundamental cellular mechanisms
    that constitute spatiotemporal order and regulate cell division.

  text: Growing microtubules are protected from depolymerization by the presence of
    a GTP or GDP/Pi cap. End-binding proteins of the EB1 family bind to the stabilizing
    cap, allowing monitoring of its size in real time. The cap size has been shown
    to correlate with instantaneous microtubule stability. Here we have quantitatively
    characterized the properties of cap size fluctuations during steadystate growth
    and have developed a theory predicting their timescale and amplitude from the
    kinetics of microtubule growth and cap maturation. In contrast to growth speed
    fluctuations, cap size fluctuations show a characteristic timescale, which is
    defined by the lifetime of the cap sites. Growth fluctuations affect the amplitude
    of cap size fluctuations; however, cap size does not affect growth speed, indicating
    that microtubules are far from instability during most of their time of growth.
    Our theory provides the basis for a quantitative understanding of microtubule
    stability fluctuations during steady-state growth.

  text: The human cerebral cortex is the seat of our cognitive abilities and composed
    of an extraordinary number of neurons, organized in six distinct layers. The establishment
    of specific morphological and physiological features in individual neurons needs
    to be regulated with high precision. Impairments in the sequential developmental
    programs instructing corticogenesis lead to alterations in the cortical cytoarchitecture
    which is thought to represent the major underlying cause for several neurological
    disorders including neurodevelopmental and psychiatric diseases. In this review
    we discuss the role of cell polarity at sequential stages during cortex development.
    We first provide an overview of morphological cell polarity features in cortical
    neural stem cells and newly-born postmitotic neurons. We then synthesize a conceptual
    molecular and biochemical framework how cell polarity is established at the cellular
    level through a break in symmetry in nascent cortical projection neurons. Lastly
    we provide a perspective how the molecular mechanisms applying to single cells
    could be probed and integrated in an in vivo and tissue-wide context.

  text: Bacterial cytokinesis is commonly initiated by the Z-ring, a dynamic cytoskeletal
    structure that assembles at the site of division. Its primary component is FtsZ,
    a tubulin-like GTPase, that like its eukaryotic relative forms protein filaments
    in the presence of GTP. Since the discovery of the Z-ring 25 years ago, various
    models for the role of FtsZ have been suggested. However, important information
    about the architecture and dynamics of FtsZ filaments during cytokinesis is still
    missing. One reason for this lack of knowledge has been the small size of bacteria,
    which has made it difficult to resolve the orientation and dynamics of individual
    FtsZ filaments in the Z-ring. While superresolution microscopy experiments have
    helped to gain more information about the organization of the Z-ring in the dividing
    cell, they were not yet able to elucidate a mechanism of how FtsZ filaments reorganize
    during assembly and disassembly of the Z-ring. In this chapter, we explain how
    to use an in vitro reconstitution approach to investigate the self-organization
    of FtsZ filaments recruited to a biomimetic lipid bilayer by its membrane anchor
    FtsA. We show how to perform single-molecule experiments to study the behavior
    of individual FtsZ monomers during the constant reorganization of the FtsZ-FtsA
    filament network. We describe how to analyze the dynamics of single molecules
    and explain why this information can help to shed light onto possible mechanism
    of Z-ring constriction. We believe that similar experimental approaches will be
    useful to study the mechanism of membrane-based polymerization of other cytoskeletal
    systems, not only from prokaryotic but also eukaryotic origin.

  text: Most kinesin motors move in only one direction along microtubules. Members
    of the kinesin-5 subfamily were initially described as unidirectional plus-end-directed
    motors and shown to produce piconewton forces. However, some fungal kinesin-5
    motors are bidirectional. The force production of a bidirectional kinesin-5 has
    not yet been measured. Therefore, it remains unknown whether the mechanism of
    the unconventional minus-end-directed motility differs fundamentally from that
    of plus-end-directed stepping. Using force spectroscopy, we have measured here
    the forces that ensembles of purified budding yeast kinesin-5 Cin8 produce in
    microtubule gliding assays in both plus- and minus-end direction. Correlation
    analysis of pause forces demonstrated that individual Cin8 molecules produce additive
    forces in both directions of movement. In ensembles, Cin8 motors were able to
    produce single-motor forces up to a magnitude of ∼1.5 pN. Hence, these properties
    appear to be conserved within the kinesin-5 subfamily. Force production was largely
    independent of the directionality of movement, indicating similarities between
    the motility mechanisms for both directions. These results provide constraints
    for the development of models for the bidirectional motility mechanism of fission
    yeast kinesin-5 and provide insight into the function of this mitotic motor.

  text: 'Cell division in prokaryotes and eukaryotes is commonly initiated by the
    well-controlled binding of proteins to the cytoplasmic side of the cell membrane.
    However, a precise characterization of the spatiotemporal dynamics of membrane-bound
    proteins is often difficult to achieve in vivo. Here, we present protocols for
    the use of supported lipid bilayers to rebuild the cytokinetic machineries of
    cells with greatly different dimensions: the bacterium Escherichia coli and eggs
    of the vertebrate Xenopus laevis. Combined with total internal reflection fluorescence
    microscopy, these experimental setups allow for precise quantitative analyses
    of membrane-bound proteins. The protocols described to obtain glass-supported
    membranes from bacterial and vertebrate lipids can be used as starting points
    for other reconstitution experiments. We believe that similar biochemical assays
    will be instrumental to study the biochemistry and biophysics underlying a variety
    of complex cellular tasks, such as signaling, vesicle trafficking, and cell motility.'
