| 英文摘要 | The envelope fusion protein f of baculoviruses is a class i viral fusion protein which play a significant role during virus entry into insect cells. f is initially synthesized as a precursor (f-0) and then cleaved into a disulfide-linked f-1 and f-2 subunits during the process of protein maturation and secretion. to facilitate further investigation into the structure and function of f protein during virus infection, monoclonal antibodies (mabs) against the f-2 subunit of helicoverpa armigera nucleopolyhedrovirus (hearnpv) (haf) were generated. two kinds of mabs were obtained according to their different recognition epitopes: one kind of mabs, as represented by 38f10, recognizes amino acid (aa) 85 to 123 of f-2 and the other kind, represented by 44d11, recognizes aa 148 to 173 of f-2. western blotand immunofluo rescence assay confirmed that both of the mabs recognized the f protein expressed in hearnpv infected cells, however, only 44d11 could neutralize hearnpv infection. the results further showed that 44d11 may not interact with a receptor binding epitope, rather it was demonstrated to inhibit syncytium formation in cells expressing the haf protein. the results imply that the monoclonal antibody 44d11 recognizes a region within haf2 that may be involved in the f-mediated membrane fusion process. |
