入侵病原体与宿主之间呈动态平衡,以维持病原体成功地寄生在宿主体内而不致宿主死亡,这是许多寄生虫感染的一个重要特征。包括曼氏血吸虫在内的许多蠕虫感染中,持续的炎症反应比病原体本身对宿主的危害更大,降低宿主的免疫反应具有重要意义。曼氏血吸虫感染后,宿主活化CD4+Th2 The dynamic equilibrium between the invading pathogen and the host to maintain the pathogen successfully parasitized in the host without host death is an important feature of many parasitic infections. In many helminth infections, including Schistosoma mansoni, the persistent inflammatory response is more damaging to the host than the pathogen itself, and it is of great importance to reduce the host’s immune response. After Schistosoma mansoni infection, the host activated CD4 + Th2
