Abstract: Amino acids other than glutamic acid are used as a metabotropic glutamate receptor activator. More preferably, aspartic acid, valine and cysteine are used as a group I metabotropic glutamate receptor activator; alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, ornithine, taurine and hydroxyproline are used as a group II metabotropic glutamate receptor activator; and cysteine is used as a group III metabotropic glutamate receptor activator.

Abstract: The invention provides a recombinant vaccinia virus strain DIs that possesses a polynucleotide encoding a foreign antigenic protein in the non-essential gene region of the chromosome DNA and expresses the antigenic protein; and provides a highly-safe, vaccinia virus vaccine containing the recombinant virus strain DIs as the active ingredient. The invention also provides a method of using the vaccinia virus strain DIs as a vector for protein expression.
