Background: CD11b/Integrin alpha M

CD11b (integrin alpha M subunit) is a type I transmembrane glycoprotein. CD11b combines with the Integrin beta 2 subunit (CD18) to form the non-covalent heterodimer Integrin alpha M/beta 2, also known as Mac-1 and complement receptor type 3 (CR3). The CD11b/CD18 (Mac-1) heterodimer has a theoretical molecular weight of 127kDa but is often observed near 170kDa due to post translational modifications. Integrins are transmembrane proteins that mediate interactions between adhesion molecules on adjacent cells and/or the extracellular matrix. Integrins have diverse roles in several biological processes, including cell migration during development, wound healing, cell differentiation, and apoptosis. The particular integrin CD11b is known as a pro-inflammatory molecule given its ability to promote phagocyte cytotoxic functions while enhancing several effector molecules such as FcGR, uPAR, and CD14 (1). In macrophages, CpG-DNA stimulates lysosomal degradation and vacuolar acidification, subsequently promoting CD11b release via TLR9 (2). During an acute infection, high CD11b/Mac-1 expression on antigen-specific CD8 (+) T cells can signify recent activation of the immune system, whereas naive T cells and virus-specific memory CD8 (+) T cells express little or no Mac-1 when exposed to a virus (3). Variations at the ITGAM gene, which encodes for the CD11b chain of the Mac-1 integrin, is one of the main genetic risk factors involved in systemic lupus erythematosus /SLE disorder (4).
