Description CD11b is the 165 kDa αM chain which combines with the CD18 β2 integrin subunit to form the Mac-1 heterodimer. It is expressed on activated lymphocytes, monocytes, granulocytes and a subset of NK cells. CD11b functions in cell-cell and cell-substrate interactions and is a ligand for C3bi, CD50 (ICAM-3), CD54 (ICAM-1) and CD102 (ICAM-2).
