甲型、乙型、非甲非乙型肝炎的肝细胞损伤机制至今尚未完全明了,大多数学者认为,非甲非乙型肝炎病毒可以在体内直接感染肝细胞导致肝细胞溶解;甲型肝炎病毒除了有这一效应外,还可以诱导宿主对病毒感染的肝细胞的免疫应答,引起肝细胞损伤,而乙型肝炎病毒只有通过后一种机制损伤肝细胞。 A, B, non-A non-hepatitis B liver cell injury mechanism has not yet fully understood, most scholars believe that non-A non-Hepatitis B virus can be directly infected in vivo hepatocytes lead to liver cell lysis; Hepatitis A virus In addition to this effect, it is also possible to induce host immune responses to virus-infected hepatocytes, causing hepatocyte damage, whereas hepatitis B virus damages liver cells only through the latter mechanism.
