NKT细胞在抗肿瘤免疫、 获得性免疫应答及免疫调节中起着重要作用。
NKT cells play an important role in anti-tumor immunity, adaptive immune responses and immunoregulation.
获得性免疫应答需要事先暴露于外界蛋白质，如病毒或细菌。先天性免疫不需要。
While adaptive immune responses require prior exposure to a foreign protein such as a virus or bacterium, innate immunity does not.
另一方面联动机体固有免疫和获得性免疫应答，抑制病毒复制，抗病毒感染，清除被病毒感染的细胞。
On the other side, they regulate the immune system to inhibit viral replication, resistance to virus infection and clear the infected cells.
所以，主要特征是感染慢性进展的患者其获得性免疫应答在功能上受到损害，这对允许病毒持续存在非常重要。
So the main feature is that a patient with a chronic evolution of infection has adaptive responses which are functionally impaired and certainly this is very important to allow virus persistence.
