In cell biology, CD11 is the α (alpha) component of various integrins, especially ones in which the β (beta) component is CD18 (β2) and mediate leukocyte adhesion. For example,

* LFA1 (CD11a/CD18) short representation of Lymphocyte Function-associated Antigen 1, also called $α_Lβ_2$ integrin
* Mac1 (CD11b/CD18) present on macrophages that is also called Macrophage-1 antigen (CR3) and $α_Mβ_2$ integrin.
* CD11c/CD18 also called complement receptor 4 (CR4) and $α_Xβ_2$ integrin.
