text: Clathrin-mediated vesicle trafficking plays central roles in post-Golgi transport.
In yeast (Saccharomyces cerevisiae), the AP-1 complex and GGA adaptors are predicted
to generate distinct transport vesicles at the trans-Golgi network (TGN), and
the epsin-related proteins Ent3p and Ent5p (collectively Ent3p/5p) act as accessories
for these adaptors. Recently, we showed that vesicle transport from the TGN is
crucial for yeast Rab5 (Vps21p)-mediated endosome formation, and that Ent3p/5p
are crucial for this process, whereas AP-1 and GGA adaptors are dispensable. However,
these observations were incompatible with previous studies showing that these
adaptors are required for Ent3p/5p recruitment to the TGN, and thus the overall
mechanism responsible for regulation of Vps21p activity remains ambiguous. Here,
we investigated the functional relationships between clathrin adaptors in post-Golgi-mediated
Vps21p activation. We show that AP-1 disruption in the ent3Δ5Δ mutant impaired
transport of the Vps21p guanine nucleotide exchange factor Vps9p transport to
the Vps21p compartment and severely reduced Vps21p activity. Additionally, GGA
adaptors, the phosphatidylinositol-4-kinase Pik1p and Rab11 GTPases Ypt31p and
Ypt32p were found to have partially overlapping functions for recruitment of AP-1
and Ent3p/5p to the TGN. These findings suggest a distinct role of clathrin adaptors
for Vps21p activation in the TGN–endosome trafficking pathway.

text: Understanding complex living systems, which are fundamentally constrained
by physical phenomena, requires combining experimental data with theoretical physical
and mathematical models. To develop such models, collaborations between experimental
cell biologists and theoreticians are increasingly important but these two groups
often face challenges achieving mutual understanding. To help navigate these challenges,
this Perspective discusses different modelling approaches, including bottom-up
hypothesis-driven and top-down data-driven models, and highlights their strengths
and applications. Using cell mechanics as an example, we explore the integration
of specific physical models with experimental data from the molecular, cellular
and tissue level up to multiscale input. We also emphasize the importance of constraining
model complexity and outline strategies for crosstalk between experimental design
and model development. Furthermore, we highlight how physical models can provide
conceptual insights and produce unifying and generalizable frameworks for biological
phenomena. Overall, this Perspective aims to promote fruitful collaborations that
advance our understanding of complex biological systems.

text: Epithelial barrier function is commonly analyzed using transepithelial electrical
resistance, which measures ion flux across a monolayer, or by adding traceable
macromolecules and monitoring their passage across the monolayer. Although these
methods measure changes in global barrier function, they lack the sensitivity
needed to detect local or transient barrier breaches, and they do not reveal the
location of barrier leaks. Therefore, we previously developed a method that we
named the zinc-based ultrasensitive microscopic barrier assay (ZnUMBA), which
overcomes these limitations, allowing for detection of local tight junction leaks
with high spatiotemporal resolution. Here, we present expanded applications for
ZnUMBA. ZnUMBA can be used in Xenopus embryos to measure the dynamics of barrier
restoration and actin accumulation following laser injury. ZnUMBA can also be
effectively utilized in developing zebrafish embryos as well as cultured monolayers
of Madin–Darby canine kidney (MDCK) II epithelial cells. ZnUMBA is a powerful
and flexible method that, with minimal optimization, can be applied to multiple
systems to measure dynamic changes in barrier function with spatiotemporal precision.

text: Neurons extend axons to form the complex circuitry of the mature brain. This
depends on the coordinated response and continuous remodelling of the microtubule
and F-actin networks in the axonal growth cone. Growth cone architecture remains
poorly understood at nanoscales. We therefore investigated mouse hippocampal neuron
growth cones using cryo-electron tomography to directly visualise their three-dimensional
subcellular architecture with molecular detail. Our data showed that the hexagonal
arrays of actin bundles that form filopodia penetrate and terminate deep within
the growth cone interior. We directly observed the modulation of these and other
growth cone actin bundles by alteration of individual F-actin helical structures.
Microtubules with blunt, slightly flared or gently curved ends predominated in
the growth cone, frequently contained lumenal particles and exhibited lattice
defects. Investigation of the effect of absence of doublecortin, a neurodevelopmental
cytoskeleton regulator, on growth cone cytoskeleton showed no major anomalies
in overall growth cone organisation or in F-actin subpopulations. However, our
data suggested that microtubules sustained more structural defects, highlighting
the importance of microtubule integrity during growth cone migration.

text: 'Clathrin-mediated endocytosis (CME) is a crucial cellular process implicated
in many aspects of plant growth, development, intra- and inter-cellular signaling,
nutrient uptake and pathogen defense. Despite these significant roles, little
is known about the precise molecular details of how it functions in planta. In
order to facilitate the direct quantitative study of plant CME, here we review
current routinely used methods and present refined, standardized quantitative
imaging protocols which allow the detailed characterization of CME at multiple
scales in plant tissues. These include: (i) an efficient electron microscopy protocol
for the imaging of Arabidopsis CME vesicles in situ, thus providing a method for
the detailed characterization of the ultra-structure of clathrin-coated vesicles;
(ii) a detailed protocol and analysis for quantitative live-cell fluorescence
microscopy to precisely examine the temporal interplay of endocytosis components
during single CME events; (iii) a semi-automated analysis to allow the quantitative
characterization of global internalization of cargos in whole plant tissues; and
(iv) an overview and validation of useful genetic and pharmacological tools to
interrogate the molecular mechanisms and function of CME in intact plant samples.'

text: 'Efficient migration on adhesive surfaces involves the protrusion of lamellipodial
actin networks and their subsequent stabilization by nascent adhesions. The actin-binding
protein lamellipodin (Lpd) is thought to play a critical role in lamellipodium
protrusion, by delivering Ena/VASP proteins onto the growing plus ends of actin
filaments and by interacting with the WAVE regulatory complex, an activator of
the Arp2/3 complex, at the leading edge. Using B16-F1 melanoma cell lines, we
demonstrate that genetic ablation of Lpd compromises protrusion efficiency and
coincident cell migration without altering essential parameters of lamellipodia,
including their maximal rate of forward advancement and actin polymerization.
We also confirmed lamellipodia and migration phenotypes with CRISPR/Cas9-mediated
Lpd knockout Rat2 fibroblasts, excluding cell type-specific effects. Moreover,
computer-aided analysis of cell-edge morphodynamics on B16-F1 cell lamellipodia
revealed that loss of Lpd correlates with reduced temporal protrusion maintenance
as a prerequisite of nascent adhesion formation. We conclude that Lpd optimizes
protrusion and nascent adhesion formation by counteracting frequent, chaotic retraction
and membrane ruffling.This article has an associated First Person interview with
the first author of the paper. '

text: β1-integrins mediate cell–matrix interactions and their trafficking is important
in the dynamic regulation of cell adhesion, migration and malignant processes,
including cancer cell invasion. Here, we employ an RNAi screen to characterize
regulators of integrin traffic and identify the association of Golgi-localized
gamma ear-containing Arf-binding protein 2 (GGA2) with β1-integrin, and its role
in recycling of active but not inactive β1-integrin receptors. Silencing of GGA2
limits active β1-integrin levels in focal adhesions and decreases cancer cell
migration and invasion, which is in agreement with its ability to regulate the
dynamics of active integrins. By using the proximity-dependent biotin identification
(BioID) method, we identified two RAB family small GTPases, i.e. RAB13 and RAB10,
as novel interactors of GGA2. Functionally, RAB13 silencing triggers the intracellular
accumulation of active β1-integrin, and reduces integrin activity in focal adhesions
and cell migration similarly to GGA2 depletion, indicating that both facilitate
active β1-integrin recycling to the plasma membrane. Thus, GGA2 and RAB13 are
important specificity determinants for integrin activity-dependent traffic.

text: The nuclear envelope (NE), a double membrane enclosing the nucleus of eukaryotic
cells, controls the flow of information between the nucleoplasm and the cytoplasm
and provides a scaffold for the organization of chromatin and the cytoskeleton.
In dividing metazoan cells, the NE breaks down at the onset of mitosis and then
reforms around segregated chromosomes to generate the daughter nuclei. Recent
data from intact cells and cell-free nuclear assembly systems suggest that the
endoplasmic reticulum (ER) is the source of membrane for NE assembly. At the end
of mitosis, ER membrane tubules are targeted to chromatin via tubule ends and
reorganized into flat nuclear membrane sheets by specific DNA-binding membrane
proteins. In contrast to previous models, which proposed vesicle fusion to be
the principal mechanism of NE formation, these new studies suggest that the nuclear
membrane forms by the chromatin-mediated reshaping of the ER.
