缺血-再灌注损伤(IRI)是一种复杂的病理生理过程,其通常以由于各种因素(例如创伤性休克、手术、器官移植、烧伤和血栓)引起的血液循环障碍为特征。在缺血组织的血流恢复后,观察到严重的代谢失调和组织结构破坏。理论上,IRI可以发生在各种组织和器官中,包括肾、肝、心肌和脑等。关于恢复缺血区域组织灌注的研究进展在降低与IRI相关的死亡率和梗死面积方面还不够。因此,严重IRI患者的临床治疗仍然是一个棘手的问题。过氧化物酶体增殖物激活受体γ(Peroxisome proliferator-activated receptor γ,PPARγ)是核转录因子超家族的一员,是改善IRI的一个有希望的治疗靶点。本文就PPARγ在IRI中的作用作一综述。本文介绍了过氧化物酶体增殖物激活受体γ的保护作用,如减轻氧化应激、抑制炎症反应和拮抗细胞凋亡,并展望了其治疗前景。
Ischemia-reperfusion injury (IRI) is a complex pathophysiological process that is often characterized as a blood circulation disorder caused due to various factors (such as traumatic shock, surgery, organ transplantation, burn, and thrombus). Severe metabolic dysregulation and tissue structure destruction are observed upon restoration of blood flow to the ischemic tissue. Theoretically, IRI can occur in various tissues and organs, including the kidney, liver, myocardium, and brain, among others. The advances made in research regarding restoring tissue perfusion in ischemic areas have been inadequate with regard to decreasing the mortality and infarct size associated with IRI. Hence, the clinical treatment of patients with severe IRI remains a thorny issue. Peroxisome proliferator-activated receptor γ (PPARγ) is a member of a superfamily of nuclear transcription factors activated by agonists and is a promising therapeutic target for ameliorating IRI. Therefore, this review focuses on the role of PPARγ in IRI. The protective effects of PPARγ, such as attenuating oxidative stress, inhibiting inflammatory responses, and antagonizing apoptosis, are described, envisaging certain therapeutic perspectives.
