Tg(TcraCl1,TcrbCl1)1Shrm

The transgene encodes a low avidity T cell receptor (TCR) that recognizes the influenza virus hemagglutinin (HA) epitope HA518-526 in the context of the H2-Kd MHC class I molecule. The rearranged Tcra and Tcrb genes, which have joined Valpha1/Jalpha11 and Vbeta8.2/D/Jbeta2.4, respectively, were amplified from cytotoxic T lymphocyte (CTL) clone 1. Clone 1 was derived from a transgenic B10.D2 mouse that expressed influenza virus HA as a self-antigen in pancreatic beta cells, which resulted in production of lower-avidity TCRs than those made by wild-type B10.D2 mice after infection with influenza virus strain A/PR/8/32.
