Abstract

Introduction: This study was aimed at establishing a system for producing virus hybrid vectored particles (VHVP) capable of carrying the RNA of the rabies virus glycoprotein (VHVP-RVGP).
Method: To produce VHVP-RVGP, HEK 293T cells were co-transfected with pCMV-Gag-Pol (from leukemia murine virus), pCMV-E1E2 (glycoproteins of hepatitis C virus), and pCMV-RVGP. VHVP-RVGP were collected 48 hours post-co-transfection and titrated by quantitative RT-PCR (RTq-PCR). The RVGP expression was detected by ELISA in lysates of Huh-7 cells treated with VHVP-RVGP.
Results: RT-qPCR assays that were conducted for the detection of cell attachment, as well as entry of VHVP-RVGP, revealed that only a small part was able to enter Huh-7 cells, indicating a limitation in the transduction process. Western blotting assays showed that MLV’s Gag-Pol protein production as well as the incorporation of HCV E1E2 into VHVP were successful.
Conclusion: In conclusion, the data demonstrated that the VHVP system was efficient in carrying the RNA-RVGP, although the HCV E1 and E2 incorporation was not efficiently presented for a proper VHVP conformation.
