<p>Allogeneic stem cell transplants (SCT) can induce curative Graft versus Tumor (GvT) reactivities in patients with hematological malignancies. The GvT reaction is mainly mediated by allo immune donor T-cells specific for polymorphic minor Histocompatibility antigens (mHags). Among these, the mHag HA-1 was found to be restricted to the hematopoietic system. Here we report the expression of HA-1 by non-hematopoietic tumor cells. While absent in normal epithelial cells, tumor cells and tumor cell lines particularly from epithelial origin, also express HA-1 and are recognized by HA-1 cytotoxic T cells. The invention provides, among others, means and methods for HA-1 specific immunotherapy for HA-1 positive patients with non-hematopoietic tumor cells.</p> |
