Abstract
Objectives: Our study aimed to explore the relationship between leptin and IFN-γ in PCOS patients, and confirmed the effect of leptin-induced IFN-γ on granulosa cells furtherly. Methods: 29 patients with PCOS and 36 healthy controls were enrolled. Leptin level and the proportion of Th1 cells were detected and association between them were analyzed. Meanwhile, peripheral blood mononuclear cells (PBMCs) isolated from PCOS patients were treated with leptin and then the proportion of Th1 was analyzed. Besides that, the apoptotic level of KGN cells was monitored after IFN-γ treatment. Results: In the circulation of PCOS patients, leptin level dramatically increased compared with controls. And, this was associated with upregulated Th1 cells proportion and IFN-γ level. In vitro, Th1 cells proportion increased after leptin treated PBMCs from PCOS patients. Furthermore, for KGN cells, the percentage of live cells decreased and later apoptosis cells increased after IFN-γ treatment.Conclusions：Our results indicated that leptin takes part in process of PCOS via inducing expression of IFN-γ. Our findings highlight the importance of the connection between leptin and inflammation in PCOS and provide new insights therapeutic strategy for this disease.
