Integrins function biology

Nettet15. jun. 2004 · In their resting state, integrins normally bind the molecules that activate them with low affinity. Upon stimulation, a cellular signal induces a conformational change in the integrin cytoplasmic domain that propagates to the extracellular domain. Integrins are transformed from a low- to a highaffinity ligand binding state. Nettet9. feb. 2024 · Activated integrins exhibit high binding affinity to ligands on the EC surface, which then triggers outside-in signaling, enhancing the avidity of integrins by inducing clustering (Fig. 1B). β2-Integrins on neutrophils, αLβ2-integrin (a.k.a lymphocyte function associated antigen-1, LFA-1) and αMβ2 (a.k.a. macrophage-1 antigen, Mac-1), are vital …
