It is also possible to use semi-allogeneic pDCs (restriction by HLA-A*0201), pulsed with tumor antigens, to induce an effective cytotoxic T-cell response in the context of melanoma in an in vivo model of humanized mice [165] or in vitro from patients’ PBMCs or tumor-infiltrating cells [166]. This evidence concerns the gene HLA-A and neoplasm.
