CD56/NCAM, the prototypical marker of human natural killer cells, promotes lytic function towards susceptible target cells by signaling through protein tyrosine kinase 2 (Pyk2).

Loss of membrane-bound ICAM-1, overexpression of soluble ICAM-1 or ILKAP activity in tumor cells induce resistance to antigen-specific cytotoxic T-cell-mediated killing independently from regulating antigen presentation, PD-L1 expression, IFN-γ, or TNF-α responsiveness.

T cell progenitor homing into the thymus requires kindlin-3 to stabilize their adhesion to vascular integrin ligands when blood flow velocities and shear rates increase during development.

CD169⁺ macrophages in the bone marrow of malaria-infected mice uptake infected red blood cells, and establish a functional interaction that is required to activate plasmacytoid dendritic cells to secrete type I interferon and leave the bone marrow.

CD31 plays a pivotal role in neutrophil migration to inflamed sites by localizing to the uropod and promoting effective actin/integrin polarization and detachment, shedding light on the molecular mechanisms underlying extravasation and inflammation response.

Inhibition of the catalytic activity of the Zap70 kinase reveals that discrete TCR-regulated events control the remodelling of the actin cytoskeleton when the cytotoxic T cell interacts with its target.

The cell surface protein CD95 mediates neutrophil slow rolling and adhesion during inflammation.

A toxin produced by the bacterium Bordetella pertussis preferentially binds to non-activated integrin complement receptor 3 outside of its ligand-binding I-domain and efficiently blocks downstream signaling of the integrin through elevation of cytosolic cAMP.

The combination of molecular imaging, genetic and pharmacological approaches revealed that BCR signaling and PKCβ-dependent activation of focal adhesion kinase (FAK) is required for B cell mechanosensing.

Cytosolic S100A8/A9 enhances Ca²⁺ availability at LFA-1 adhesion sites, facilitating neutrophil recruitment and extravasation by supporting proper integrin signaling and cytoskeletal rearrangement.
