Integrin alpha X beta 2, also called CD11c/CD18, p150/95 or complement receptor type 4 (CR4), is one of four beta 2 integrins. The non-covalent heterodimer of 150 kDa alpha X/CD11c and 95 kDa beta 2/CD18 integrin subunits is commonly used as a marker for dendritic cells (DC) and classically activated macrophages (M1), but is also expressed on hairy cell leukemias, with lower amounts on other myeloid cells and activated B, NK and some cytotoxic T cells. Inflammation enhances surface expression of alpha X beta 2 in states such as obesity (adipose DC), asthma (lung DC) and hypertriglyceridemia (circulating monocytes), increasing the adhesive capacity of the cells and contributing to pathology. The alpha X vWFA or I‑domain, which contains the adhesion sites, forms the N‑terminal head region with the alpha X beta-propeller and the beta 2 vWFA domain.
