| 英文摘要 | Variants of hepatitis b surface antigen (hbsag) influenced its antigenicity and immunogenicity. in our study, we aim to investigate biological significance of amino acid (aa) substitutions in hbsag, q129 n and t131 n/m133 t, for glycosylation, antigenicity and immunogenicity of variant hbsag (vthbsag) and viral replication. expression plasmids of vthbsag with aa substitutions q129 l, t123 n, q129 n and t131 n/m133 t were constructed. immunofluorescence (if) staining and western blot were simultaneously utilized to examine expression of vthbsag proteins in huh7 cells transfected with vthbsag constructs. vthbsag of q129 n and t131 n/m133 t created new n-glycosylation and displayed perinuclear distribution by if staining with the anti-ha. antigenicity of vthbsag of q129 n and t131 n/m133 t was reduced compared with wild type (wt) hbsag. in addition, we discovered impaired ability to induce anti-hbs responses against wthbsag in mice immunized with plasmids phbsag- q129 n and t131 n/m133 t. even so, efficient protective response toward wild type hbv can be primed by the two vthbsags in mice. further, we discovered that vthbsag with q129 n distinctly impaired hbv replication capacity, but vthbsag with t131 n/m133 t had no impact on viral replication. thus, we conclude that vthbsag with q129 n or t131 n/m133 t creates new n-glycosylation and interferes with both the antigenicity and immunogenicity of vthbsag. and vthbsag with q129 n impaired hbv replication ability. |
