中枢神经系统(CNS)是一个免疫特权部位,而炎症与许多CNS疾病有关.过氧化物酶体增殖物激活受体(PPARs)是调节免疫和炎症反应的核激素受体家族。已证明PPARα、γ和δ同种型的特异性配体在多发性硬化(MS)、阿尔茨海默病、帕金森病和创伤/中风的动物模型中有效,这表明它们可用于治疗神经炎性疾病。NF-κB和Jak-Stat信号通路的激活以及炎性细胞因子的分泌在CNS疾病的发病机制中至关重要。有趣的是,PPAR激动剂通过调节免疫细胞中的炎症信号网络来减轻CNS疾病。在这篇文章中,我们回顾了PPARs如何调节中枢神经系统疾病的神经炎症信号网络的现有知识。
Central nervous system (CNS) is an immune privileged site, nevertheless inflammation associates with many CNS diseases. Peroxisome proliferator-activated receptors (PPARs) are a family of nuclear hormone receptors that regulate immune and inflammatory responses. Specific ligands for PPARα, γ, and δ isoforms have proven effective in the animal models of multiple sclerosis (MS), Alzheimer's disease, Parkinson's disease, and trauma/stroke, suggesting their use in the treatment of neuroinflammatory diseases. The activation of NF-κB and Jak-Stat signaling pathways and secretion of inflammatory cytokines are critical in the pathogenesis of CNS diseases. Interestingly, PPAR agonists mitigate CNS disease by modulating inflammatory signaling network in immune cells. In this manuscript, we review the current knowledge on how PPARs regulate neuroinflammatory signaling networks in CNS diseases.
