过氧化物酶增殖体激活受体γ的抗炎作用及机制的体外研究的开题报告 【摘要】近年来，过氧化物酶增殖体激活受体γ（PPAR-γ）被发现可以调节炎症反应，发挥抗炎作用。本研究旨在探究PPAR-γ在体外对炎症反应的调节作用及其机制。首先，采用文献调研方法对PPAR-γ的结构、功能、基因调控及信号通路进行综述，为后续的实验设计提供理论支持。其次，使用LPS诱导RAW264.7细胞炎性反应，利用西方印迹法和RT-qPCR测定PPAR-γ的表达水平和其下游炎性因子的表达情况，进一步验证PPAR-γ的抗炎作用。最后，通过药物作用和分子筛选等方法，探究PPAR-γ的调节机制。预计本研究对深入了解PPAR-γ的生物学功能及其在炎症反应中的作用机制具有重要的指导意义。 【关键词】过氧化物酶增殖体激活受体γ，炎症反应，基因调控，信号通路，抗炎作用 【Abstract】In recent years, Peroxisome proliferator-activated receptor gamma (PPAR-γ) has been found to regulate inflammation and has anti-inflammatory effects. The aim of this study was to investigate the regulatory effects and mechanisms of PPAR-γ on the inflammatory response in vitro. First, PPAR-γ structure, function, gene regulation and signaling pathway were summarized by literature research methods to provide theoretical support for subsequent experimental design. Secondly, LPS-induced RAW264.7 cells were used to induce inflammatory reactions. Western blot and RT-qPCR were used to determine the expression levels of PPAR-γ and downstream inflammatory factors, and further verify the anti-inflammatory effects of PPAR-γ. Finally, drug action and molecular screening methods were used to explore the regulatory mechanism of PPAR-γ. It is expected that this study will have important guiding significance for a deeper understanding of the biological functions of PPAR-γ and its role in inflammatory reactions. 【Keywords】Peroxisome proliferator-activated receptor gamma, inflammatory response, gene regulation, signaling pathway, anti-inflammatory effect.
