Abstract
We describe the expression and immunogenicity of a recombinant chimeric protein (HAV VP1-Fc) consisting of human hepatitis A virus VP1 and an Fc antibody fragment using a replicating vector based on Beet curly top virus (BCTV) in Agrobacterium-infiltrated Nicotiana benthamiana leaves. Recombinant HAV VP1-Fc was expressed with a molecular mass of approximately 68 kDa. Recombinant HAV VP1-Fc, purified using Protein A Sepharose affinity chromatography, elicited production of specific IgG antibodies in the serum after intraperitoneal immunization. Following vaccination with recombinant HAV VP1-Fc protein, expressions of IFN-γ and IL-4 were increased in splenocytes at the time of sacrifice. Recombinant VP1-Fc from infiltrated tobacco plants can be used as an effective experimental immunogen for research into vaccine development.Entities:
