乙型肝炎病毒包膜上的前Ｓ１、前Ｓ２蛋白及表面抗原为ＨＢＶＤＮＡ的Ｓ区前Ｓ１、前Ｓ２及Ｓ基因的编码产物。ｐｒｅＳ蛋白参与ＨＢＶ的组装、分泌和侵入肝细胞的机制，而机体对ｐｒｅＳ的免疫应答成为清除肝细胞内ＨＢＶ以及阻止病毒侵入肝细胞提供重要的防御作用。本文...
The preS1 and preS2 proteins on the envelope of hepatitis B virus and the surface antigens are the coding products of the preS1, preS2 and S genes of the S region of HBVDNA. The preS protein is involved in the mechanism of HBV assembly, secretion and invasion of hepatocytes. The immune response of preS to the host cells provides an important defensive function for clearing HBV in hepatocytes and preventing the virus from invading hepatocytes. This article...
