基于MCP-1-CCR2信號(hào)通路研究清達(dá)顆粒對(duì)自發(fā)性高血壓大鼠心臟炎癥的影響及作用機(jī)制

基于MCP-1-CCR2信號(hào)通路研究清達(dá)顆粒對(duì)自發(fā)性高血壓大鼠心臟炎癥的影響及作用機(jī)制摘要：本研究旨在探究清達(dá)顆粒對(duì)自發(fā)性高血壓大鼠心臟炎癥的影響及作用機(jī)制，以MCP-1/CCR2信號(hào)通路為研究重點(diǎn)。實(shí)驗(yàn)選取自發(fā)性高血壓大鼠作為研究對(duì)象，分別給予清達(dá)顆粒和生理鹽水治療，并通過HE染色、免疫組化和Westernblot等方法檢測(cè)心臟炎癥水平及信號(hào)通路的變化。結(jié)果顯示，清達(dá)顆粒治療組心臟炎癥水平顯著降低，且MCP-1/CCR2信號(hào)通路的激活程度明顯下降。進(jìn)一步分析發(fā)現(xiàn)，清達(dá)顆粒的作用機(jī)制可能與其對(duì)MCP-1/CCR2信號(hào)通路中核轉(zhuǎn)錄因子NF-κB的抑制作用有關(guān)。綜上，清達(dá)顆粒能夠有效改善自發(fā)性高血壓大鼠心臟炎癥，其作用機(jī)制可能涉及到MCP-1/CCR2信號(hào)通路的調(diào)控。
