%J 科学通报(英文版) %D 1998 %I %X In order to make entire HBV pmSAg secrete from mammalian cells, we conatmcted an eukaryotic expression vector by using leader sequence of human interleukin-2 (IL-2) as secretory signal peptide, and using high hydmphilic amino acids as the linker between IL-2 C end and preSAg N end. As a result, the IL-2preS fusing protein could be secreted from mamalian cells transfected with the reconstructed vector and the expression efficiency was identical to that of natural IL-2. It was considered that the retentive effect of preSlAg could be successfully bypassed. The results not only laid a theoretical and practical foundation for constructing specific gene vaccine against HBV persistent infection, but also supplied experimental evidence for studying modulation of protein secretory expression. %K hepatitis B %K gene vaccine %K gene immunization %K preS antigen %K mammalian cells %K secretion
