Background: IL-7R alpha/CD127

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 (1, 2). Mature mouse IL-7 R alpha consists of a 219 amino acid (aa) extracellular domain (ECD) with one fibronectin type III domain and a WSxWS motif, a 25 aa transmembrane segment, and a 195 aa cytoplasmic domain (3). Within the ECD, mouse IL-7 R alpha shares 67% and 79% aa sequence identity with human and rat IL‑7 R alpha, respectively. IL-7 R alpha associates with the common gamma chain ( gamma _c) to form the functional high affinity IL-7 receptor complex (4). The gamma _c is also a subunit of the receptors for IL-2, -4, -9, -15, and -21. Human and mouse IL-7 show cross-species activity through the IL-7 receptor (3, 5). 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 (6, 7). It is expressed early in B cell development, prior to the appearance of surface IgM (6). In mouse, IL-7 activation of IL‑7 R alpha is critical for both T cell and B cell lineage development (8). In human it is required for T cell but not for B cell development (9). IL‑7 induces the down regulation and shedding of cell surface IL-7 R alpha (10). IL-7 R alpha additionally associates with TSLP R to form the functional receptor for thymic stromal lymphopoietin (11, 12). TSLP indirectly regulates T cell development by modulating dendritic cell activation (2, 13). Knockout of TSLP R in mice provokes minor changes in B and T cell development compared to those seen with IL‑7 R alpha deletion (8, 14). 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 (11, 12, 15, 16).
