Th17 cells are central drivers of autoimmune pathology, including multiple sclerosis (MS), yet the endogenous metabolic signals that shape their pathogenic differentiation remain incompletely defined. Prostaglandin D₂ (PGD2) is traditionally viewed as an extracellular mediator in allergic diseases. Here, we identify PG...
