RNA-sequencing identifies differentially expressed genes in T helper 17 cells in peritoneal fluid of patients with endometriosis

•Th17 cells are present in peritoneal fluid of endometriosis patients.•Th17 cells in peritoneal fluid of endometriosis patients are CCR4+CCR6+.•Peritoneal fluid Th17 cells undergo significant transcriptomic changes in endometriosis.•Peritoneal fluid Th17 cells at different stages of endometriosis have different gene expression profiles.
