Anti-Peptide WIY T cell receptor (YAe62), pCDTCR1 (TCR-YC0971)


All products and services are For Research Use Only and CANNOT be used in the treatment or diagnosis of disease.

YAe62 and 3K-36 are two highly cross-reactive T cells, both produced by immunization with IAb-p3K. Transgenic expression of these TCRs in H-2b mice lacking IAb leads to the development of mature CD8+ T cells, suggesting that, despite their MHCII reactivity, these TCRs can be positively selected on H-2b MHCI molecules and thus might react with an H-2b MHCI presented antigen. A common contaminating 8-mer peptide, WIYVYRPM (pWM) was identified by mass spectrometry in the semi-purified peptide preparations and was then synthesized de novo. The Yae62 T cells responded strongly to pWM, and recognized pWM presented by Kᵇ, but not Dᵇ.

Target

  • Introduction
  • Unlike B cells that binds many different types of antigens, T cells bearing αβ antigen receptors (TCRs) usually react only with peptides from foreign antigens bound in the grooves of major histocompatibility complex proteins (MHC). Recent evidence suggests that this bias toward MHC presented antigens is caused by two phenomena: 1) the sequences of TCR variable regions themselves, which appear to have been selected during evolution to have some intrinsic affinity for MHC and 2) positive and negative selection in the thymus, which allows the maturation of only those thymocytes that bear TCRs that react weakly with self MHC⁺ self peptides.
