γδ TCR variants Currently, γδ T cells have been considered as unique innate-like T cells with TCRs that can easily recognition of highly conserved antigens. Meanwhile, evidence has suggested that analyzing the γδ TCR repertoire is important to obtain meaningful data for the immune system features, the causes, and the progression of the disease. At present, the main obstacle to the problem of the γδ TCR repertoire services is that traditional methods are not sufficient to characterize the TCR repertoire in-depth.
