WebNov 8, 2016 · The TCR - a heterodimer that is uniquely rearranged in each T cell during its development - is the sole determinant of T cell specificity ( DembiĆ et al., 1986 ). Accordingly, transfer of the α and β genes encoding a tumor-reactive αβ TCR can impart anti-tumor reactivity to a cancer patient’s T cells ( Clay et al., 1999 ). WebBlocking the TCR-pMHC interaction on OTI T cell or expressing CD8 alone on a hybridoma abolished the enhancement. The enhancement is also dependent on the integrity of lipid rafts and the normal function of PTP. In contrast, the antibody CT-CD8 can inhibit the binding of pMHC to the T cells and interfere with the TCR-pMHC interaction.
