CD11b is a 165-170kD type I transmembrane glycoprotein also known as aM integrin, Mac-1, CR3, and C3biR. CD11b non-covalently associates with integrin B2 (CD18) and is expressed on granulocytes, monocytes/macrophages, dendritic cells, NK cells, and subsets of T and B cells. CD11b/CD18 is critical for the transendothelial migration of monocytes and neutrophils. It is also involved in granulocyte adhesion, phagocytosis and neutrophil activation. CD11b/CD18 interacts with ICAM-1 (CD54), ICAM-2 (CD102), ICAM-4, CD14, CD23, heparin, iC3b, fibrinogen and Factor X. This antibody inhibits heterotypic adhesion of granulocytes in response to fMLP.
