The permeability of phospholipid vesicles to a class I-restricted epitope derived from the melanoma-associated protein, gp100280–288, and its possible effects on epitope degradation by fibroblast-expressed proteolytic enzymes were studied. The results indicate that the majority of the peptide may not be contained within the lipid vesicles when administered for vaccination.
