| Epstein–Barr virus (EBV) associated with several diseases such as contagious mononucleosis
chronic active EBV infection, and diverse sorts of malignant tumors. Therefore, using applicable
vaccines could be advantageous for public health. Yet, the vaccine has been unavailable to
protect from EBV so far. In the current study, to develop a multi-peptide vaccine for EBV and
assess its expression in Pichia pastoris yeast system, three immunodominant sequences in glycoprotein
(gp) 85, gp350 and latent membrane protein 1 (LMP1) were chosen. To construct fusion
peptide, -GGGGS- liker was applied. After cloning the fusion peptide in the pPICZαA expression
vector, this recombinant vector processed and transfected into Pichia pastoris host cells. The
expression of high level of EBV fusion peptide was confirmed by dot blot and SDS-PAGE
procedures. The Pichia pastoris is capable of supporting EBV fusion peptide expression. The
application of this fusion peptide as a peptide vaccine to fight EBV is suggested. |
