[Construction and evaluation of hepatitis C virus (HCV) DNA vaccine containing E2-gAD fusion gene]

To rational design HCV DNA vaccine candidates and evaluate their specific We design to construct two DNA vaccine candidates, one consists of immunity to HCV in mice.

We design to construct two DNA vaccine candidates, one consists of E2 (the envelope glycoprotein 2 of HCV) gene only, the second consists of E2-gAD (Globular Domain of Human Adiponectin) fusion gene via overlapping PCR. Confirm the expression of the DNA vaccines by Western blotting, and then vaccinated by injection of DNA vaccines with gene electrotransfer (GET) in BALB/c mice. The immune response was measured by IFN-gamma ELISPOT.

The DNA vaccine candidate consists of E2-gAD could effectively express in vitro , and it could induced a higher anti-HCV T cell response in mice than the one consists of E2 only.

The HCV DNA vaccine consists of E2-gAD fusion can increase the immunity of the E, to some extend, and the research paved a way to develop and optimize the novel HCV DNA vaccine.
