Th17 cells: from gut homeostasis to CNS pathogenesis

Jane H Buckner et al. Trends Immunol. 2022 Mar.

Abstract

Th17 cells play crucial roles in host-microbe interactions, but can also promote chronic inflammation and tissue pathology. Factors influencing Th17 cell heterogeneity and effector functions in different inflammatory contexts remain unclear. Schnell et al. demonstrate that intestinal Th17 cells form a reservoir from which pathogenic Th17 cells can be elicited during severe tissue inflammation.

Figure 1:. Intestinal Th17 cells contribute to the pathogenic Th17 cell pool during CNS inflammation in mice.
Homeostatic Th17 cells are enriched within intestinal tissues during homeostasis and recirculate through the spleen. During inflammation IL-23 acts directly upon SLAMF6+ Th17 cells to promote their conversion to pathogenic Th17 and ex-Th17 cells that produce IFN-γ and GM-CSF, and promote CNS tissue destruction.
