Background: CD7

CD7, also known as Leu-9, is an approximately 40 kDa glycosylated and palmitoylated transmembrane protein in the immunoglobulin superfamily (1). Mature human CD7 consists of a 155 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 39 aa cytoplasmic domain (2). Within the ECD, human CD7 shares 43% and 41% aa sequence identity with mouse and rat CD7, respectively. CD7 is expressed on T cells (2, 3), NK cells (4), myeloid progenitor cells (5), and CD19+ B progenitor cells (6). Among CD8+ T cells, the CD7-bright population preferentially contains naïve and memory cells, while more weak expressors are primarily effector cells (7). CD7 associates in cis with CD3 and CD45 and in trans with SECTM1 (8, 9). Ligation of CD7 with antibodies or SECTM1 co‑stimulates the activation and proliferation of CD4+ and CD8+ T cells (10, 11) and NK cells (4, 9). It also enhances integrin-mediated adhesion of these cells to Fibronectin, ICAM-1, and VCAM-1 (3, 12). CD7 additionally mediates the Galectin-1 induced apoptosis of T cells (13) and facilitates the fusion of HIV-1 with target cells (14).
