Target Information
The T cell antigen receptor (TCR) consists of a ligand-specific alpha/beta heterodimer non-covalently associated with five invariant chains including the CD3 gamma/delta/eta and zeta subunits, all of which are required for efficient surface expression.
T cell activation through the TCR induces cellular differentiation and/or proliferation and the production of lymphokines and cytokines. Both the CD3 and TCR zeta subunits are proposed to be responsible for the intracellular signal transduction events.
The majority of T cells in blood, lymph, and secondary lymphoid organs express TCR alpha/beta heterodimers, whereas T cells expressing TCR gamma/delta heterodimers are mainly localized in epithelial tissues and infection sites.
The subunits of TCR heterodimers are covalently bonded and associate with CD3 subunits in the endoplasmic reticulum to form a functional TCR-CD3 complex. Lack of expression of any chain halts surface expression.
T cell receptors (TCR) discriminate foreign from self-peptides presented by MHC class II molecules, which is essential for effective adaptive immune responses. Recognition of self-peptides by TCRs is linked to autoimmune diseases, and mutant self-peptides have been associated with tumors.
Engagement of TCRs by bacterial superantigens can cause toxic shock syndrome. Autoantibodies to V beta segments of TCRs have been identified in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), potentially modulating TH1-mediated inflammatory responses.
Most human T cells express TCR alpha-beta and either CD4 or CD8 (single positive, SP). A smaller subset lacks both CD4 and CD8 (double negative, DN), which may increase in autoimmune or immunodeficiency disorders. Gamma-delta T cells, primarily found in epithelial tissues, show less TCR diversity and distinct antigen recognition, with some subsets exhibiting antitumor and immunoregulatory activity.
