Abstract excerpt
The major subset of human blood gammadelta T lymphocytes expresses the variable-region genes Vgamma9 and Vdelta2. These cells recognize non-peptidic phosphoantigens that are present in some microbial extracts, as well as the beta(2)-microglobulin-deficient Burkitt's lymphoma Daudi. Most cytotoxic human Vgamma9/Vdelta2 T cells express inhibitory natural killer cell receptors for HLA class I that downmodulate the...
