Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.

Diverse biophysical properties of β1 and β3 integrin transmembrane and cytoplasmic domains result in distinct mechanisms of integrin activation and function.

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.

Stromal cell levels and localization of active α₅β₁-integrin are regulated by desmoplastic extracellular matrix control of α_vβ₅-integrin signaling, and predict clinical outcomes for pancreatic and renal cancer patients.

Naturally short-lived turquoise killifish undergo systemic and mucosal spontaneous decline in antibody-repertoire diversity during aging, recapitulating in a few months the aging-dependent decline of adaptive immunity.

Functional attachments between muscles and tendons require pentameric Thrombospondin-4, revealing novel roles both as an integrin ligand and extracellular matrix scaffold.

By binding with their type 1 pili to the cell surface receptor CD14, pathogenic E. coli suppress the capacity of dendritic cells to activate T cells.

Comprehensive proteomic investigation and functional studies unravel an essential role of differentiated glioma cell-secreted fibromodulin (FMOD) in regulating glioblastoma tumor growth by inducing angiogenesis by activating integrin-dependent Notch signaling in endothelial cells, highlighting FMOD as a potential therapeutic target.

Impairment of the autocrine S1PR1-Gi signaling on HEVs results in high-endothelial cell apoptosis, reduced CCL21-secretion from HEVs, and cessation of HEV-DC interactions and lymphocyte immigration across the high-endothelial barrier.

A hitherto unknown role of Piezo1 mechanosensors in chemotactic migration of human T cells is identified, linking focal adhesion formation to integrin recruitment.
