CA 2530038

A composition containing an expression vector which encodes an antigen recognized by CD4+ helper T lymphocyte and an antigen recognized by CD8+ cytotoxic T lymphocyte (CTL) (in particular, a tumor-specific antigen, a tumor- associated antigen or a cell-associated antigen), preferably containing an expression vector encoding interferon-gamma. Specific examples of the antigen recognized by CD4+ helper T lymphocyte include cancer/testis antigens such as NY-ESO-1, while specific examples of the antigen recognized by CD8+ cytotoxic T lymphocyte (CTL) (in particular, a tumor-specific antigen, a tumor- associated antigen or a cell-associated antigen) include HER-2/neu and cancer/testis antigens such as NY-ESO-1, MAGE and SAGE.

L'invention concerne une composition renfermant un vecteur d'expression codant un antigène reconnu par un lymphocyte T auxiliaire CD4+ et un antigène reconnu par un lymphocyte T cytotoxique CD8+ (CTL) (plus particulièrement, un antigène spécifique à une tumeur, un antigène associé à une tumeur ou un antigène associé à une cellule), contenant de préférence un vecteur d'expression codant interféron-gamma. Des exemples spécifiques de l'antigène reconnu par le lymphocyte T auxiliaire CD4+ comprennent des antigènes du cancer/testicules, notamment NY-ESO-1, alors que des exemples spécifiques de l'antigène reconnu par le lymphocyte T cytotoxique CD8+ (CTL) (plus particulièrement, un antigène spécifique à une tumeur, un antigène associé à une tumeur ou un antigène associé à une cellule) comprennent des antigènes HER-2/neu et cancer/testicules, notamment NY-ESO-1, MAGE et SAGE.
