The peroxisome proliferator-activated receptor (PPAR) gamma is a member of the nuclear hormone receptor superfamily of ligand-activated transcription factors. Thiazolidinediones, pharmacological ligands for PPARgamma, are currently used in the management of type 2 diabetes. Peroxisome proliferator-activated receptor gamma is expressed in the lung and pulmonary vasculature, and its expression is reduced in the vascular lesions of patients with pulmonary hypertension. Furthermore, thiazolidinedione PPARgamma ligands reduced pulmonary hypertension and vascular remodeling in several experimental models of pulmonary hypertension. This report reviews current evidence that PPARgamma may represent a novel therapeutic target in pulmonary hypertension and examines studies that have begun to elucidate mechanisms that underlie these potential therapeutic effects.
过氧化物酶体增殖物激活受体(PPAR)γ是配体激活转录因子核激素受体超家族的成员。噻唑烷二酮类药物是PPARγ的药理学配体,目前用于2型糖尿病的治疗。过氧化物酶体增殖物激活受体γ在肺和肺血管系统中表达,在肺动脉高压患者的血管病变中其表达降低。此外,噻唑烷二酮类PPARγ配体在几种肺动脉高压实验模型中降低了肺动脉高压和血管重塑。本报告综述了目前关于PPARγ可能是肺动脉高压新治疗靶点的证据,并审视了已开始阐明这些潜在治疗作用机制的研究。
