WebMar 19, 2024 · Human Vγ9Vδ2 T cells respond to microbial infections and malignancy by sensing diphosphate-containing metabolites called phosphoantigens, which bind to the intracellular domain of butyrophilin 3A1, triggering extracellular interactions with the Vγ9Vδ2 T cell receptor (TCR). WebThe dominant Vγ2Vγ2 T cell subset recognizes phosphoantigen and exists only in humans and nonhuman primates. Despite the discovery of γ δ T cells >30 y ago, a proof-of-concept study has not been done to prove the principle that the Vγ2Vδ2 T cell subset is protective against Mycobacterium tuberculosis and other infections.
WebDifferentiation, distribution and immune regulation of human IL-22-producing T cells in infections remain unknown. Here, we demonstrated in a nonhuman primate model that M. tuberculosis infection resulted in apparent increases in numbers of T cells capable of producing IL-22 de novo without in vitro Ag stimulation, and drove distribution of these … WebSep 13, 2012 · In the case of phosphoantigens generated in tumor cells, particularly after tretament with n-BP, the presented data are in line with the assumption that the intracellularly generated phosphoantigens (ie, IPP) act through the intracytoplasmic domain of one CD277 isoform to induce a membrane reorganization of the CD277 molecule (see …
