CD11 Antigens

A group of three different integrin alpha chains (CD11a, CD11b, CD11c) that are associated with an invariant integrin beta-2 chain (CD18 ANTIGENS). The three resulting leukocyte-adhesion molecules (RECEPTORS, LEUKOCYTE ADHESION) are LYMPHOCYTE FUNCTION-ASSOCIATED ANTIGEN-1; MACROPHAGE-1 ANTIGEN; and ANTIGEN, P150,95.
