Integrins for leukocyte localization

Nettet1. des. 2003 · The four leukocyte-specific β2 integrins (αLβ2, αMβ2, αXβ2, αDβ2) are found on T cells, αLβ2 (leukocyte function-associated antigen-1; LFA-1) being the most abundant and widespread in expression. Nettet15. mai 2009 · Because αIIbβ3 integrins are constantly exposed to fibrinogen, it is vital to keep them inactive so as to prevent pathological platelet aggregation and thrombus formation. Similarly, during inflammation leukocytes require integrin activation in order to adhere to and migrate across the endothelium on their way to affected tissues.
