Most human peripheral blood γδ T lymphocytes respond to hitherto unidentified
mycobacterial antigens. Four ligands from Mycobacterium tuberculosis strain H37Rv that
stimulated proliferation of a major human γδ T cell subset were isolated and partially
characterized. One of these ligands, TUBag4, is a 5′ triphosphorylated thymidine-
containing compound, to which the three other stimulatory molecules are structurally related.
These findings support the hypothesis that some γδ T cells recognize nonpeptidic ligands.
