Target Information

CD83 cell surface antigen is a 40–45 kDa glycoprotein expressed by peripheral blood dendritic cells. Peripheral lymphocytes can be induced to express low levels of CD83 after culture in agents such as Con A or PHA. In immunohistology, CD83 is strongly expressed by interfollicular interdigitating reticulum cells and weakly by cells within germinal centres. It is also expressed by Langerhans cells in the skin.

The CD83 antigen is a 186-amino-acid single-chain glycoprotein and a member of the immunoglobulin superfamily, composed of an extracellular V-type Ig-like domain, a transmembrane region, and a short 40-amino-acid cytoplasmic tail. CD83 undergoes extensive post-translational glycosylation, resulting in a molecular weight approximately twice that of the predicted core protein.

CD83⁺ cells exhibit a unique immunophenotype distinct from T, B, NK, or myelomonocytic lineages. They coexpress high levels of MHC class II molecules along with T cell markers (CD2, CD5), B cell markers (CD40, CD78), myeloid markers (CD13, CD33, CD36), and various cytokine receptors. Diseases associated with CD83 dysfunction include plague and Rift Valley Fever.
