The tetraspanin CD81 uses its ectodomain to export CD19, and the interaction of the two proteins is dynamically regulated by B cell activation state.

Differential physical interactions between bacteria in mixed microcolonies trigger cell sorting.

Interaction strength in Notch signaling determines lateral inhibition patterning and drives fate in the unidimensional cell arrangement of the zebrafish notochord.

Intersectin2 deficiency is associated with impaired humoral responses to viral infection and B-cell-intrisic defects in germinal centre formation, resulting from the reduced ability of intersectin2-KO B cells to establish cognate interactions with helper T cells.

β-Catenin-mediated expansion of nephron progenitors is independent of direct β-catenin/chromatin engagement, while progenitor induction proceeds with a β-catenin-driven switch of repressive TCFL1/TCFL2 to activating TCF7/LEF1 factors on transcriptionally poised enhancers.

A generally applicable two-hybrid assay demonstrates that MHC class I heavy chains devoid of beta-2 microglobulin associate within and across allotypes, with implications for endocytosis and autoimmunity.

New role of P2Y₂-αV integrin interactions in ATP-driven pancreatic cancer cell invasion provides a potential anti-metastatic target for pancreatic cancer.

EphrinB2 promotes glioblastoma stem-like cell malignancy through the interplay of cell-autonomous and non-cell-autonomous mechanisms and its targeting suppresses tumourigenesis in preclinical models of human glioblastoma.

Confined magnetotactic bacteria exhibit circling and U-turn trajectories explained by a competition of alignment with a magnetic field and alignment along the confining walls as well as considerable cell-to-cell heterogeneity.

Human yolk sac-like cells, which share characteristics with the post-implantation human hypoblast, can model the interaction between the epiblast and hypoblast that occurs during early human development.
