Abstract

Inflammation induced during infection can both promote and suppress immunity. This contradiction suggests that inflammatory cytokines affect the immune system in a context-dependent manner. Here we show that nonspecific bystander inflammation conditions naive CD4(+) T cells for enhanced peripheral Foxp3 induction and reduced effector differentiation. This results in inhibition of immune responses in vivo via a Foxp3-dependent effect on antigen-specific naive CD4(+) T cell precursors. Such conditioning may have evolved to allow immunity to infection while limiting subsequent autoimmunity caused by release of self-antigens in the wake of infection. Furthermore, this phenomenon suggests a mechanistic explanation for the idea that early tuning of the immune system by infection affects the long-term quality of immune regulation.
