This has, for example, been shown for Yersenia pestis [182], Plasmodium yoelii [180], dengue virus [171], HIV [183,237], the cancer/testis antigen 1A (known as CTAG1A or NY-ESO-1), or the Her2/neu breast cancer antigen in a protective model with NT2.5 tumor cells [189]. This evidence concerns the gene ERBB2 and neoplasm.
