Lack of Alloantigen-Specific Cytotoxic T Cell Activity in the TCR-γδT Cell Subpopulation of Alloantigen-Immune Chickens
Recently T cell receptor (TCR) homologues of the mammalian TCR-αβ (TCR2) and the TCR-γδ(TCR1) have been defined in the chicken (Sowder et al. 1988; Cihak et al. 1988; Chen et al. 1988), where the TCR1 cells may constitute approximately 20–65 % of the T cell pool (Cihak et al. in preparation). In addition to the TCRl and TCR2 cells a third subpopulation of T cells has been identified in the chicken (Chen et al. 1989; Cooper et al. 1989). These cells, provisionally named “TCR3” cells, are TCR-αβ T cells which use the Vß2 gene product whereas TCR2 cells use the Vßl gene product (M.D. Cooper, personal communication and in this issue).
