脓毒症是一种发病率和死亡率都很高的临床问题,它是由全身全身炎症反应引起的。Toll样受体(Toll-like Receptor,TLRs)在脓毒症的炎症反应和组织损伤中起重要作用。在这项研究中,我们证明了TLR9抑制在脓毒症中对失调的炎症反应和组织损伤的保护作用。TLR9缺乏可降低盲肠结扎穿孔(CLP)诱导的脓毒症小鼠的死亡率。TLR9基因敲除小鼠的脾、肺和肝脏中p38活性降低,Akt磷酸化增强。此外,TLR9缺乏可降低CLP后炎性细胞因子水平,减轻脾细胞凋亡。这些结果表明,抑制TLR9可能为脓毒症的治疗提供一种新的治疗策略。
Sepsis, a major clinical problem with high morbidity and mortality, is caused by overwhelming systemic host-inflammatory response. Toll-like receptors (TLRs) play a fundamental role in induction of hyperinflammation and tissue damage in sepsis. In this study, we demonstrate a protective role of TLR9 inhibition against the dysregulated inflammatory response and tissue injury in sepsis. TLR9 deficiency decreased the mortality of mice following cecal ligation and puncture (CLP) -induced sepsis. TLR9 knockout mice showed dampened p38 activation and augmented Akt phosphorylation in the spleen, lung and liver. In addition, TLR9 deficiency decreased the levels of inflammatory cytokines and attenuated splenic apoptosis after CLP. These results indicate that TLR9 inhibition might offer a novel therapeutic strategy for the management of sepsis.
