Stepwise differentiation from precursor intermediates and distinct Th1 checkpoints promote CD4 Th1 cell differentiation during chronic viral infection

Proceedings of the National Academy of Sciences, Volume 123, Issue 5, February 2026. SignificanceTh1 CD4+cells are essential for viral control during chronic infection, but their differentiation becomes progressively restricted. Here, we identify a Th1 precursor intermediate subset, describe the stepwise differentiation of Th1 cells ...Read More
