Self-reactivity controls functional diversity of naive CD8+ T cells by co-opting tonic type I interferon.

Abstract excerpt

The strength of the T cell receptor interaction with self-ligands affects antigen-specific immune responses. However, the precise function and underlying mechanisms are unclear. Here, we demonstrate that naive CD8+ T cells with relatively high self-reactivity are phenotypically heterogeneous owing to varied responses to type I interferon, resulting in three distinct subsets, CD5loLy6C-, CD5hiLy6C-, and CD5hiLy6C+...
