Complement receptor 4 (CD11c/CD18), p150/95 is a member of the beta(2)-integrin family of adhesion molecules and is considered an important phagocytic receptor. The role of p150/95 in the development of central nervous system demyelinating diseases, including multiple sclerosis, remains unexplored.

CD11c/CD18 is a member of the leukocyte integrin family, heterodimeric adhesion molecules that interact with a diverse repertoire of ligands, including bacterial lipopolysaccharide (LPS). Their role as signal transducing receptors remains uncertain. Aberrant integrin (CR4; alpha(x)beta2; CD11c/CD18) oscillations on neutrophils in a mild form of pyoderma gangrenosum. CR3 (CD11b/CD18) and CR4 (CD11c/CD18) Are Involved in Complement-Independent Antibody-Mediated Phagocytosis of Cryptococcus neoformans.
