CD4 and neoplasm: Given that heat shock-conditioned OECCL lysates potentially contain a large number of OEC-associated antigens that can produce a broad number of antigenic epitopes on DCs for priming T cell responses, we investigated whether CD4+ and CD8+ tumor-specific IFN-γ-secreting T cells were also being elicited in vitro by autologous HLA-A2+ MOVL1- or MOVL2-DCs.
