Background: CD27/TNFRSF7

CD27, also known as TNFRSF7, is an approximately 55 kDa transmembrane protein in the TNF receptor superfamily. It functions as a co‑stimulatory molecule that supports lymphocyte activation and survival (1). Mature mouse CD27 consists of a 159 amino acid (aa) extracellular domain (ECD) with three TNFR cysteine-rich repeats, a 21 aa transmembrane segment, and a 47 aa cytoplasmic domain (2). Within the ECD, mouse CD27 shares 63% and 85% aa sequence identity with human and rat CD27, respectively. CD27 is expressed as a disulfide‑linked homodimer that carries N‑linked and O‑linked glycosylation (3, 4). Proteolytic cleavage of CD27 results in the shedding of a 28-32 kDa fragment of the ECD (4). CD27 is weakly expressed on naïve T cells and NK cells and is up‑regulated upon cell activation (4, 5). It is also up‑regulated on activated germinal center B cells, plasma cells, and a subset of memory B cells (6, 7). CD27 binds to the transmembrane glycoprotein CD27 Ligand/CD70 which is expressed on activated B cells, activated T cells, and dendritic cells (1, 8, 9). This interaction contributes to the activation and survival of CD4+ helper T cells (8‑11), CD8+ effector T cells (12, 13), memory T cells (10), and NK cells (5, 14). Ligation of CD27 on B cells promotes germinal center formation and the expansion and affinity maturation of memory B cell responses (6, 15).
