Description : Human CD28 is an important costimulatory molecule found on all CD4+ T cells and on about half of the CD8+T cells. T cell activities attributed to CD28 include, prevention of anergy, induction of cytokine gene transcription, stabilization of cytokine mRNAs and activation of CD8+ cytotoxic T lymphocytes. The ligands for CD28, identified as CD80 (B7-1) and CD86 (B7-2), are immunoglobulin superfamily monomeric transmembrane glycoproteins of 60 kd and 80 kd, respectively.
