Alteration at a single amino acid residue in the T cell receptor alpha chain complementarity determining region 2 changes the differentiation of naive CD4 T cells in response to antigen from T helper cell type 1 (Th1) to Th2.

Abstract excerpt

To study whether changes in the structure of a T cell receptor (TCR) at a single peptide-contacting residue could affect T cell priming with antigenic peptide, we made transgenic mice with a point mutation in the TCR alpha chain of the D10.G4.1 (D10) TCR and bred them to D10 beta chain transgenic mice. The mutation consisted of a leucine to serine substitution at position 51 (L51S), which we had already...
