<h4>ABSTRACT</h4> To determine the nature of CD4 + T cells that provide ‘help’ for generating robust anti-tumor CD8 + cytotoxic T cell (CTL) responses, we profiled the transcriptomes of patient-matched CD4 + and CD8 + T cells present in the tumor micro-environment (TME) and analyzed them jointly using integrated weighted gene correlation network analysis. We found the follicular helper T cell (T FH ) program in CD4 + T cells was strongly associated with proliferation and tissue-residency in CD8 + CTLs. Single-cell analysis demonstrated the presence of T FH -like cells and features linked to cytotoxic function and their provision of CD8 + T cell ‘help’. Tumor-infiltrating T FH -like cells expressed PD-1 and were enriched in tumors following checkpoint blockade, suggesting that they may respond to anti-PD-1 therapy. Adoptive transfer or induction of T FH cells in mouse models resulted in augmented CD8 + CTL responses and impairment of tumor growth, indicating an important role of T FH -like CD4 + T cells in anti-tumor immunity.
