过氧化物酶体增殖体激活受体γ（ PPARγ）是调节目的基因表达的核内受体转录因子超家族成员。 PPARγ主要表达于脂肪组织及免疫系统，与脂肪细胞分化、机体免疫及胰岛素抵抗关系密切。近年来，PPARγ与炎症反应的关系逐渐成为研究热点。研究表明，肥胖往往伴随着低等级的慢性炎症反应。“,”Peroxisome proliferator-activated receptor gamma ( PPARγ) is the member of the nuclear receptor transcription factors superfamily to regulate gene expression .PPAR gamma is mainly expressed in adipose tissue and immune system , it is closely related to insulin resistance , adipocytes differentiation and body immunity.In recent years, the relationship between PPAR gamma and inflammation has gradually become a hot research topic.Studies have shown that, obesity is often complicated by low levels of chronic inflammation .
