The present invention contemplates dendritic cell compositions. The dentritic cell compositions employ MHC class-II targeting signals fused to an antigen or fragment thereof to obtain MHC II presentation of the antigen or fragment thereof. In particular, the invention refers to a dendritic cell vaccine comprising dendritic cells expressing a MHC class-II targeting signal fused to an antigen or fragment thereof. Dendritic cell vaccines for the stimulation of an immune response against melanoma-associated antigen are also described.
