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 is also known as integrin alpha-M beta-2, Mac-1, and CR3 (complement receptor 3).
CD11b is expressed on:
- Monocytes/macrophages
- Granulocytes
- Activated lymphocytes
- NK cell subsets
- Dendritic cell subsets
- Microglia in the brain
Functions as receptor for:
- ICAM-1 (CD54)
- ICAM-2 (CD102)
- ICAM-4 (CD242)
- CD14
- CD50
- CD23
- Heparin
- iC3b
- Fibrinogen
- Factor X
These interactions are critical for cell-cell and cell-matrix adhesion. CD11b is expressed on 8% of spleen cells, 44% of bone marrow cells, and less than 1% of thymocytes, and is commonly used as a microglial marker in nervous tissue. Expression increases during monocyte maturation and varies among tissue macrophages.
Diseases associated with CD11b dysfunction include systemic lupus erythematosus and ITGAM-related susceptibility to lupus.
