HBV/HCV virus-like particle

   
   

Chimeric antigens derived from hepatitis B virus (HBV) and hepatitis C virus (HCV) are described which form virus-like particles when co-expressed with an excess of hepatitis B virus surface antigen (HBsAg). The chimeric antigens are fusion proteins containing an immunogenic peptide derived from an HCV protein coupled to the amino terminus of HBsAg. Also described are nucleic acid constructs and vectors for transfection of cells and expression of the chimeric antigens. The invention further provides methods for producing HBV/HCV virus-like particles containing the chimeric antigens, cell lines for producing the virus-like particles, combination vaccines containing the virus-like particles, and DNA vaccines that express the virus-like particles.

Os antígenos chimeric derivados do vírus do hepatitis B (HBV) e do vírus do hepatitis C (HCV) são descritos que dão forma vírus-como partículas quando co-expressados com um excesso do antígeno da superfície do vírus do hepatitis B (HBsAg). Os antígenos chimeric são proteínas da fusão que contêm um peptide immunogenic derivado de uma proteína de HCV acoplada ao amino término de HBsAg. São descritos também as construções e os vetores do ácido nucleic para o transfection das pilhas e a expressão dos antígenos chimeric. A invenção mais adicional fornecem métodos produzindo HBV/HCV vírus-como as partículas que contêm os antígenos chimeric, as linhas da pilha para produzir vírus-como partículas, conter das vacinas da combinação vírus-como partículas, e as vacinas do DNA que expressam vírus-como partículas.
