摘要
Mature T lymphocytes carrying the conventional alpha beta T cell receptor (TCR) recognize peptide antigens in the context of MHC class I (CD8+) and MHC class II (CD4+) antigens, respectively, In striking contrast, human gamma delta T lymphocytes recognize unconventional antigens via their heterodimeric TCR in a non-MHC-restricted fashion. In this brief review, we discuss recent progress in the identification of ligands that are specifically recognized by human gamma delta T cells. II appears that gamma delta T cells have evolved to supplement the cellular immune response towards antigens that are not seen by alpha beta T lymphocytes, Copyright (C) 2000 S. Karger AG, Basel.
