Anti-TCRg/d-PE

11F2 recognizes the human gamma/delta T cell receptor (TCR). The T cell receptor is a heterodimeric glycoprotein associated with the CD3 antigen. The TCR consists of a alpha and a beta chain (TCRa/b) or a gamma and a delta chain (TCRg/d). Clone 11F2 reacts with a framework epitope of the gamma/delta T cell → receptor. The gamma and delta TCR chains are composed of constant and variable regions, each encoded by distinct gene segments. The gamma chain forms either disulfide-linked or non-disulfide-linked heterodimers with the delta-subunit. The gamma/delta T cell → receptor is present on a subset of T lymphocytes in peripheral blood, intestinal epithelium, lymph node, thymus, and spleen. TCR gamma/delta is involved in the recognition of certain bacterial, self-CD1 molecule, and tumor antigens bound to MHC class I. Gamma/delta T cells are mainly CD4 negative and CD8 negative. T cells expressing the gamma/delta TCR have been shown to play a role in oral tolerance, innate immune response for some tumor cells, and autoimmune disease. Antigen presentation by gamma/delta T cells has been reported.
