Interleukin 7 Receptor alpha (IL-7 R alpha ), also known as CD127, is a 75 kDa hematopoietin receptor superfamily member that plays an important role in lymphocyte differentiation, proliferation, and survival. IL-7 R alpha associates with the common gamma chain to form the functional high affinity IL-7 receptor complex. IL 7 R alpha is expressed on double negative (CD4-CD8-) and CD4+ or CD8+ single positive T cells as well as on CD8+ memory T cells and their precursors. It is expressed early in B cell development, prior to the appearance of surface IgM.
In mouse, IL-7 activation of IL 7 R alpha is critical for both T cell and B cell lineage development. In human it is required for T cell but not for B cell development. IL 7 induces the down regulation and shedding of cell surface IL-7 R alpha. IL-7 R alpha additionally associates with TSLP R to form the functional receptor for thymic stromal lymphopoietin. TSLP indirectly regulates T cell development by modulating dendritic cell activation. The complexity of IL-7 R alpha biology is suggested by the competition between IL-7 and TSLP for receptor binding and by the ability of IL 7 R alpha to form functional complexes with SCF R and HGF R.
