Cover Story: This study investigates the role of programmed cell death protein 1 (PD-1) in the development and progression of endometriosis, a chronic disease with suspected immunological roots. Sixty-two patients undergoing laparoscopic surgery were analyzed, 47 with endometriosis and 15 controls. Peritoneal fluid and blood samples were examined by flow cytometry to assess PD-1 expression on immune cells. The results showed a significant increase in PD-1-expressing CD56+ CD16+ NK cells in endometriosis patients’ peritoneal fluid (p = 0.021). PD-1 levels also varied with body mass index and smoking status and were higher in patients with symptomatic or extensive disease. These findings suggest immune escape mechanisms similar to those observed in cancer, highlighting PD-1 as a potential target for future immunomodulatory therapies in endometriosis. View this paper
