NCIt definition : A recombinant vaccinia virus encoding a modified peptide of the gp100 melanoma-melanocyte
antigen with potential use in cancer immunotherapy. gp100 human antigen is a wild
type self-antigen expressed by melanocytes, pigmented retinal cells and most melanomas.
This recombinant vaccinia Mgp100 encodes a fragment epitope of gp100 bearing 2 amino
acids substitution; T- M at position 210 and 288 A - V at position 210. This modification
may stimulate tumor infiltrating lymphocytes (TIL) more efficiently.;
