Abstract

The invention identifies tumor-associated antigens that may be used for immunotherapy of malignancies in patients having undergone an allogeneic stem cell transplantation, whereby the therapy is mediated by induction of a graft versus tumor immune response. The invention discloses minor histocompatibility antigens encoded by polymorphisms in reading frames present in the hECGF-1 gene. The invention provides peptides comprising polymorphic minor histocompatibility binding peptides or fragments, which may be in the context of an MHC molecule. The invention also provides T cell receptors and T lymphocytes capable of binding to these minor histocompatibility antigens, preferably in the context of MHC molecules. The molecules and cells of the invention can be used for treatment of subjects and manufacture of medicaments for the treatment of subjects suffering from malignancies expressing the hECGF-1 protein.
