An optimized design of the rabies virus glycoprotein (G protein) for use within DNA vaccines has been suggested. The design represents a territorially adapted antigen constructed taking into account glycoprotein amino acid sequences of the rabies viruses registered in the Russian Federation and the vaccine Vnukovo-32 strain. Based on the created consensus amino acid sequence, the nucleotide codon-optimized sequence of this modified glycoprotein was obtained and cloned into the pVAX1 plasmid (a vector of the last generation used in the creation of DNA vaccines). A twofold increase in this gene expression compared to the expression of the Vnukovo-32 strain viral glycoprotein gene in a similar vector was registered in the transfected cell culture. It has been demonstrated that the accumulation of modified G protein exceeds the number of the control protein synthesized using the plasmid with the Vnukovo-32 strain viral glycoprotein gene by 20 times. Thus, the obtained modified rabies virus glycoprotein can be considered to be a promising DNA vaccine antigen.
