| Open AccessExpression of E-cadherin by CD8+ T cells promotes their invasion into biliary epithelial cells
The presence of CD8+ T cells in the cytoplasm of biliary epithelial cells (BEC) has been associated with primary biliary cholangitis. Here, the authors demonstrate that CD8+ T cells invade BEC using a mechanism that is dependent on cytoskeletal rearrangements and E-cadherin:β-catenin interactions.

Tools for high spatiotemporal control of cell-cell adhesions are lacking. Here, authors propose an optogenetic tool, opto-E-cadherin, that allows reversible control of E-cadherin-mediated cell-cell adhesions with blue light.

| Open AccessNeural crest E-cadherin loss drives cleft lip/palate by epigenetic modulation via pro-inflammatory gene–environment interaction
Cleft lip and palate is a common birth defect thought to involve both genetic and environmental components in its etiology. Here they identify a mechanism involving inflammation and E-cadherin mutations that reduces neural crest migration, leading to craniofacial defects.

| Open AccessIn mitosis integrins reduce adhesion to extracellular matrix and strengthen adhesion to adjacent cells
Adopting a round cell morphology before mitosis is crucial. Here, the authors show that in mitosis integrins binding to ligands do not engage the actomyosin cortex, which curbs cell-extracellular matrix adhesion, though β1 integrins are rewired to synergize with cadherins in mitotic cell-cell adhesion.

| Open AccessInhibition of negative feedback for persistent epithelial cell–cell junction contraction by p21-activated kinase 3
Actin and myosin operate at cell–cell junctions during junctional shortening. Here the authors show that prolonged actomyosin contractility can compromise junctional shortening, and that Pak3 is required for attenuation of abnormal active protrusive structure and thus keeps junction contraction, appropriate E-cadherin distribution, and junction shortening in Drosophila.

| Open AccessA junctional PACSIN2/EHD4/MICAL-L1 complex coordinates VE-cadherin trafficking for endothelial migration and angiogenesis
Communication between endothelial leader and follower cells during collective cell migration is crucial for vascular development. Here, the authors show that PACSIN2 guides collective cell migration and angiogenesis by recruiting a protein trafficking complex to asymmetric cell-cell junctions, controlling local junction plasticity.

| Open AccessInjury triggers fascia fibroblast collective cell migration to drive scar formation through N-cadherin
Extensive scars develop in deep wounds as opposed to superficial wounds but it is unclear why. Here, the authors use live imaging of physiologic wounds and scars formed ex vivo to show that fascia fibroblasts upregulate N-cadherin allowing coordinated cell migration that drives extensive scar formation of deep wounds.

| Open AccessZEB1/NuRD complex suppresses TBC1D2b to stimulate E-cadherin internalization and promote metastasis in lung cancer
Non-small cell lung cancer (NSCLC) is often associated with metastasis to the lungs. Here, the authors perform independent screens and identify NuRD as a co-repressor of ZEB1, and demonstrate TBC1D2b as a downstream target of ZEB1/NuRD complex regulating NSCLC metastasis.

Mechanical forces play a crucial role during morphogenesis, but how these are sensed and transduced in vivo is not fully understood. Here the authors apply a FRET tension sensor to live zebrafish and study changes in VE-cadherin tension at endothelial cell-cell junctions during arterial maturation.

| Open AccessTyrosine dephosphorylated cortactin downregulates contractility at the epithelial zonula adherens through SRGAP1
Epithelial cell-cell adhesions are contractile junctions, but whether contractility can be down-regulated is not known. Here the authors report how tyrosine dephosphorylation of the cytoskeletal scaffold, cortactin, recruits the RhoA antagonist SRGAP1 to relax adherens junctions in response to HGF.

| Open AccessCell division orientation is coupled to cell–cell adhesion by the E-cadherin/LGN complex
Cell–cell adhesion and oriented cell division play key roles in tissue architecture, but how they are coordinated is not known. Here, the authors show that E-cadherin interacts with LGN, and thereby provides a cortical cue that serves to stabilize cortical attachment of astral microtubules at cell–cell adhesions, thus orienting the mitotic spindle.

Formation and reinforcement of E-cadherin-mediated adhesion depends on intracellular trafficking and interactions with the actin cytoskeleton, but how these are coordinated is not known. Here the authors conduct a focused phenotypic screen to identify new pathways regulating cell–cell junction homeostasis.

| Open AccessThe F-BAR protein pacsin2 inhibits asymmetric VE-cadherin internalization from tensile adherens junctions
Cell-cell adhesion of endothelial tissue, mediated by the adhesion molecule VE-cadherin, is tightly regulated. Here the authors show that the F-BAR domain protein pacsin2 is recruited to the trailing end of mechanically unbalanced Focal Adherens Junctions, where it inhibits internalization of VE-cadherin and protects cell-cell adhesion.

How the shape of the sternum is regulated is unclear. Here, the authors identify the Dchs1-Fat4-planar cell polarity pathway as controlling cell orientation and cell intercalation of mesenchymal cells that form skeletal condensations for the mouse sternum, which defines the relative dimensions of the sternum.

E-cadherin is an adhesion molecule mediating cell-cell adhesion; correct localization is important but how localization is controlled is not clear. Here the authors use Drosophilaas a model system to distinguish three distinct trafficking pathways that direct E-cadherin to the zonula adherens.

Cadherins are typically involved in cell-cell adhesion, however cadherin-11 promotes cell migration through an undefined mechanism. Langhe et al.show that cadherin-11 mediates adhesion to the cell matrix at focal adhesions through interaction with syndecan-4.

Yes-associated protein regulates endothelial cell contact-mediated expression of angiopoietin-2
Angiogenesis is regulated by dynamic changes in endothelial cell contact. Here, the authors show that signals from endothelial cell junctions affect the subcellular localization and function of Yes-associated protein, ultimately modifying angiopoietin-2 expression and angiogenic activity of endothelial cells.

Integrin β1 controls VE-cadherin localization and blood vessel stability
The role of integrin β1 in angiogenesis is poorly understood. Here, the authors show that integrin β1 regulates murine angiogenesis and adherens junction integrity by controlling VE-cadherin localization, myosin light chain phosphorylation and the function of the Rap1/MRCK and Rho/Rho-kinase pathways.

Resolving the molecular mechanism of cadherin catch bond formation
Cadherins are calcium-dependent adhesion molecules that can form catch bonds, characterized by longer lifetimes at higher force. Here, Manibog et al. determine the mechanism of catch bond formation, whereby tension induces hydrogen bond formation between opposing extracellular domains in a calcium-dependent manner.

N-cadherin regulates spatially polarized signals through distinct p120ctn and β-catenin-dependent signalling pathways
Cells often migrate in groups, requiring delicate coordination of adhesion between members of the group and between the group and its surroundings. Here the authors show that this distinction is underpinned by differential N-cadherin signalling through p120catenin and β-catenin.

| Open AccessPhosphorylation of VE-cadherin is modulated by haemodynamic forces and contributes to the regulation of vascular permeability in vivo
Vascular endothelial-cadherin is a junctional protein implicated in the control of vascular permeability. Orsenigo et al.find that vascular endothelial-cadherin is phosphorylated in veins but not in arteries of mice, and that this sensitizes vessels to rapid changes in permeability in response to inflammatory mediators.

Cadherin selectivity filter regulates endothelial sieving properties
Endothelial cells provide a vital barrier system to the passage of water and ions but not large plasma proteins. Using fluorescently labelled dextrans, the authors show that regions of high or low adherens junction density differentially restrict the passage of molecules up to 70 kDa in size.
