In contrast, 25 % of iNKT cells from MC-38-CEA tumor-bearing mice treated with αGC/sCD1d-anti-CEA fusion protein still produced IFNγ (Fig. 6a), while only 9 % iNKT cells were IFNγ+ in mice treated with the irrelevant αGC/sCD1d-anti-HER2 fusion protein. This evidence concerns the gene ERBB2 and neoplasm.
