IL17A and polycystic ovary syndrome: KEGG pathway enrichment analysis revealed that the potential targets of CFDT for obese PCOS were mainly immune regulation and inflammation-related signaling pathways, such as the IL-17 signaling pathway, FoxO signaling pathway, Th17 cell differentiation, TCR signaling pathway, PI3K-Akt signaling pathway, and Toll-like receptor signaling pathway.
