Project description:Tumor-infiltrating T lymphocytes (TILS) plays a pivotal role in immunotherapy, but the dynamic relationships of the T cells reacted on the therapy remains elusive. T cell receptor (TCR) repertoire, serving as lineage tags, could track these tumor-infiltrating T lymphocytes. Here, in order to deconvolve TILS heterogeneity after therapy in a comprehensive catalog, we presented single T-cell analysis by RNA-seq and TCR tracking of a 22,590 T cells from colorectal carcinoma under control conditions and during Stellera chamaejasme and anti-PD-1 activation. We reveal a highly complex microenvironment which profoundly molds T lymphocytes, as well as the combinatorial impact of TCR utilization on phenotypic diversity. scRNA-seq identified distinct CD8 T cells subtypes CD8 naïve and CD8 cytoxic cells(CD8 CTL), also, CD4 T cell subpopulations Regulatory T(Tregs) cells and T helper cell 17(Th-17). Stellera chamaejasme activation triggered CTSW, ICOS, etc. in CD8 T cells, whose the dramatic differentiation into from a single time point. At the same time, Stellera chamaejasme plus anti-PD-1 therapy have a strikingly effect on the balance between Tregs and Th-17. Our integrated analyses provide a powerful avenue to disclose the TILS in CRC based on TCR and demonstrate novel functional interactions among TILS subpopulations during Stellera chamaejasme plus anti-PD-1 therapy.
