Background

CD28 is a receptor for the proteins CD80 (B7.1) and CD86 (B7.2) that is constitutively expressed on naïve T cells. It provides co-stimulatory signals necessary for T cell activation and survival. CD28 has been identified in stromal cells, plasma cells, neutrophils, and eosinophils in bone marrow. Evidence shows that CD28 enhances TCR signaling as well as mediates specific signaling events. CD28 levels in human T cells diminish with age, with CD8+ T cells being the most impacted. These cells are part of a population of antigen-experienced cells that may be pro- or anti-inflammatory. In autoinflammatory and autoimmune disorders such as multiple sclerosis and rheumatoid arthritis, there is an increase in the number of circulating oligoclonal CD4+CD28 T cells. The importance of CD28 costimulatory signals in T cell activity makes it an appealing target for medicines that aim to regulate the function of both effector and regulatory T cells.
