DEPDC1-LP2 and MPHOSPH1-LP1 induced cross-priming of CTLs in vivo. HLA-A2 or HLA-A24 Tgm were immunized with DEPDC1-LP2 or MPHOSPH1-LP1 emulsified in IFA. After vaccination, CD8+ T cells isolated from the inguinal lymph nodes were stimulated ex vivo with BM-DCs pulsed with DEPDC1-A2302–311 (A), DEPDC1-A24294–302 (B), MPHOSPH1-A2282–291 (C), MPHOSPH1-A24278–286 (D), or HIV-A2 or -A24 SPs. The number of IFN-γ-producing murine CD8+ T cells was analyzed by ex vivo ELISPOT assays. Representative data from three independent experiments (two or three mice in each group) performed in duplicate or triplicate are shown.
