Target Information
CD11b (integrin alpha-M, ITGAM, integrin alpha-X, ITGAX) is a 165 kDa adhesion molecule that associates non-covalently with integrin beta-2 (CD18).
The CD11b/CD18 heterodimeric complex, known as integrin alpha-M beta-2, Mac-1, or CR3 (complement receptor 3), is expressed on:
- Monocytes/macrophages
- Granulocytes
- Activated lymphocytes
- A subset of NK cells
- A subset of dendritic cells
- Microglia in the brain
CD11b/CD18 acts as a receptor for ICAM-1 (CD54), ICAM-2 (CD102), ICAM-4 (CD242), CD14, CD50, CD23, heparin, iC3b, fibrinogen, and Factor X.
These interactions are essential for cell-cell and cell-matrix adhesion.
Expression details:
- 8% of spleen cells
- 44% of bone marrow cells
- <1% of thymocytes
- Commonly used as a microglial marker in nervous tissue
CD11b expression increases during monocyte maturation and varies among macrophage types.
Peritoneal macrophages express higher levels of CD11b than splenic macrophages.
Dysfunction of CD11b is associated with systemic lupus erythematosus and ITGAM-related susceptibility to lupus.
