• Background: CD8 is a cell surface glycoprotein molecule expressed on the surface of a subset of T cells, generally the cytotoxic/suppressor cells, as well as on some natural killer cells. There are two forms of CD8, either as an alpha-alpha homodimer or alpha-beta heterodimer. The pathological role of CD8 has been observed in familial CD8 deficiency.
  A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8a. CD8 binds to MHC class 1 and through its association with protein tyrosine kinase p56lck plays a role in T cell development and activation of mature T cells. For mature T-cells, CD4 and CD8 are mutually exclusive, so anti-CD8, generally used in conjunction with anti-CD4. It is a useful marker for distinguishing helper/inducer T-lymphocytes, and most peripheral T-cell lymphomas are CD4+/CD8-. Anaplastic large cell lymphoma is usually CD4+ and CD8-, and in T-lymphoblastic lymphoma/leukemia, CD4 and CD8 are often co-expressed. CD8 is also found in littoral cell angioma of the spleen.
