Abstract: This work aims to prepare lentivirus vaccine with a follicle-stimulating hormone receptor(FSHR)and investigate the immunological effect of it on mice. The gene(fshr366)of extracellular region of FSHR was cloned into lentivirus vector. The recombinant plasmids were transfected into the 239T cells by the method of lipidosome transfection, and the virus particles(Lenti-FSHR366)with target gene were produced after encapsulation. The expressions of fshr366 mRNA and FSHR366 protein in 293T cells infected by Lenti-FSHR366 were detected by RT-PCR and Western blot. For evaluating the immunological effects, BALB/c mice were intraperitoneally inoculated with single immunization of fshr366-carring virus, collecting the blood samples from the orbits of mice at day 0, 14, 21 and 28 after immunization, then ELISA method was used to detect the specificity of the sera from immunized mice and determine the titer of the antibody. The RE digestion and DNA sequencing results showed the gene fragment of fshr366 was successfully cloned into lentivirus vector. After transfection to 293T cells with the encapsulated lentivirus particles carrying fshr366, the detection results by RT-PCR and Western blot indicated the expression of gene fshr in the cells at transcription and protein level. The results of ELISA revealed that the humoral immune response in mice rose on day 14 after single immunization through intraperitoneally injection of lentivirus particles carrying fshr366, the titer of antibody was 1:1600.
