CD4+ helper T cells endow cDC1 with cancer-impeding functions in the human tumor micro-environment

The group of Yanling Xiao and Jannie Borst has a recent publication in Nature Communications that shows how CD4+ T cells promote tumor immunity.

Despite their low abundance, presence of classical type 1 dendritic cells (cDC1) in tumors positively correlates with patient survival. The research demonstrates that cDC1 are key for relaying CD4+ T-cell help for cytotoxic T cell (CTL) responses.

CD4+ helper T cells endow cDC1 with cancer-impeding functions in the human tumor micro-environment

Single cell RNA-sequencing revealed that CD4+ T-cell help optimizes cDC1 in many functions that support antigen cross-presentation and CTL priming. The transcriptomic cDC1 'help' signature was linked to the patient situation by examining bioinformatic datasets. "We robustly identified 'helped' cDC1 in the micro-environment of a multitude of human cancer types. As predicted from the functional effects of CD4+ T-cell help, the transcriptomic signature of 'helped' cDC1 correlates with tumor infiltration by CTLs and T-helper cells, overall survival and response to PD-1- targeting immunotherapy” explains Xin Lei (in picture in the middle), who was highly involved in this research project.
