Abstract

Apoptosis supports tissue homeostasis and prevents immune disorders by removing damaged and functionally aberrant cells. Here, Ou et al. utilized genetic, pharmacological, and proteomic approaches focused on sulfur amino acid catabolism to discover that hydrogen sulfide (H<sub>2</sub>S) release during apoptosis suppresses Th17 cell differentiation, thus providing therapeutic targets for autoimmune diseases.
