TH and breast neoplasm: In our previous study, we identified a HLA-A2 specific CTL epitope of TAL6, called peptide A2-5, that could induce HLA-A2-restricted immunity and TAL6 specific cytotoxicity of CTLs by the immunization of A2-5 formulated in incomplete Freund's adjuvant (IFA) with a universal Th epitope Pan-DR peptide against TAL6-expressing breast tumors [17].
