Background: CD8
Given its role in the immune system, CD8-deficiency in T-cells is a hallmark of many diseases and pathologies (8-10). Specifically, CD8+ T-cell deficiency is prevalent in chronic autoimmune diseases including multiple sclerosis, rheumatoid arthritis, ulcerative colitis, Crohn's disease, type 1 diabetes mellitus, and Graves' disease (8). Furthermore, cancers or chronic infection can lead to CD8 T-cell exhaustion as the continual antigen presentation and inflammatory signals eventually cause the CD8+ T-cells to lose functionality (9, 10). However, animal models and clinical studies have suggested that T-cells are capable of being reinvigorated using inhibitory receptor blockade resulting in better disease outcomes and these exhausted T-cells may be a potential therapeutic target (9, 10).
Alternative names for CD8 includes CD antigen: CD8a, CD8 antigen, alpha polypeptide (p32), CD8a molecule, CD8A, Leu2 T-lymphocyte antigen, LEU2, MAL, OKT8 T-cell antigen, p32, T cell co-receptor, T8 T-cell antigen, T-cell antigen Leu2, T-cell surface glycoprotein CD8 alpha chain, and T-lymphocyte differentiation antigen T8/Leu-2.
