We re-examined the observation that γδ T cells, when transferred from mice tolerized to an inhaled conventional antigen (Ag), suppress the allergic IgE response to this Ag specifically. Using ovalbumin and hen egg lysozyme in crisscross fashion, we confirmed the Ag-specific IgE regulatory effect of the γδ T cells. Although only Vγ4+ γδ T cells are regulators, the Ag specificity does not stem from specificity of their γδ TCRs. Instead, the Vγ4+ γδ T cells failed to respond to either Ag, but rapidly acquired Ag-specific regulatory function in vivo following i.v. injection of non-T cells derived from the spleen of Ag-tolerized mice. This correlated with their in vivo Ag acquisition from i.v. injected Ag-loaded splenic non-T cells, and in vivo transfer of membrane label provided evidence for direct contact between the injected splenic non-T cells and the Vγ4+ γδ T cells. Together, our data suggest that Ag itself, when acquired by γδ T cells, directs the specificity of their IgE suppression.
