许多在健康动物中成功的抗炎策略在脓毒症的临床试验中失败,部分原因是脓毒症通常涉及免疫功能低下的患者,并且大量淋巴细胞凋亡阻止了免疫调节。在这里,我们报告了一组新的调节性淋巴细胞能够重建胆碱能抗炎调节,并提供治疗优势败血症。迷走神经控制健康小鼠的炎症,但不控制败血症小鼠。同样,迷走神经和胆碱能激动剂不能控制脾切除和裸动物的炎症。与典型的抑制性CD25+细胞不同,CD4+CD25−淋巴细胞在免疫功能低下和脓毒症动物中重建迷走神经和胆碱能激动剂的抗炎潜力。这些胆碱能淋巴细胞重新建立脾保护和胆碱能激动剂的潜力,以拯救免疫功能低下的动物建立败血症。这些结果揭示了这些新的调节性淋巴细胞作为先天免疫反应的神经调节的第一个已知的生理靶点,以及脓毒症的潜在治疗靶点。
Many anti-inflammatory strategies successful in healthy animals fail in clinical trials for sepsis, in part, because sepsis normally involves immunocompromised patients, and massive lymphocyte apoptosis prevents immunomodulation. Here we report a new set of regulatory lymphocytes able to reestablish the cholinergic anti-inflammatory modulation and to provide therapeutic advantages in sepsis. Vagus nerve controls inflammation in healthy, but not in septic mice. Likewise, vagus nerve and cholinergic agonists fail to control inflammation in splenectomized and nude animals. Unlike typical suppressor CD25+ cells, CD4+CD25− lymphocytes reestablish the anti-inflammatory potential of the vagus nerve and cholinergic agonists in immunocompromised and septic animals. These cholinergic lymphocytes reestablish splenic protection and the potential of cholinergic agonists to rescue immunocompromised animals from established sepsis. These results reveal these new regulatory lymphocytes as the first known physiological target for neuromodulation of the innate immune responses, and a potential therapeutic target for sepsis.
