| 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.

| Open AccessPlasmodium sporozoite search strategy to locate hotspots of blood vessel invasion
Plasmodium sporozoites actively migrate in the dermis and enter blood vessels to induce infection. Here, Formaglio et al. show that Plasmodium sporozoites alternate global superdiffusive skin exploration and local subdiffusive blood vessel exploitation to find intravasation hotspots associated with pericytes, enter the blood circulation and start malaria infection.

Cell migration regulates diverse (patho)physiological processes, including cancer metastasis. Here the authors show that the chloride ion channel SWELL1 and the ion exchanger NHE1 are preferentially enriched at the trailing and leading edges, respectively, of migrating cells and regulate cell volume to propel confined cells, favouring breast cancer cell extravasation and metastasis.

The mechanism of force production by invadopodia is unclear. Here, the authors show that cell surface MT1-MMP when in contact with collagen, induces Arp2/3 branched actin polymerisation on the concave side of invadopodia, which generates a pushing force along with collagen cleavage by MT1-MMP to invade.

| Open AccessMatrix mechanical plasticity regulates cancer cell migration through confining microenvironments
In order to metastasize, cancer cells must migrate through basement membranes and dense stroma, and proteases are thought to be required due to the confining nature of these matrices. Here the authors use synthetic matrices to show that cells can migrate through confining matrices using force generation alone, rather than protease degradation, if the matrices exhibit mechanical plasticity.
