近年来越来越多的证据显示 ,神经系统和免疫系统存在着密切的相互影响。免疫系统在接受抗原刺激迅速作出反应的同时 ,还将免疫信息传递到中枢神经系统 ,影响该系统的活动并接受其调节。目前 ,对免疫信息向中枢传递的途径有几种假说 ,其中受到重视的是神经机制 ,特别是迷走神经 In recent years, more and more evidence shows that there is close interaction between the nervous system and the immune system. Immune system in response to antigen stimulation to respond quickly, but also the immune information transmitted to the central nervous system, affecting the activity of the system and accept its regulation. At present, there are several hypotheses on the ways in which immune messages are transmitted to the central nervous system, and the most important ones are the neural mechanisms, especially the vagus nerve
