Maturation of dendritic cells with lipopeptides that represent vaccine candidates for hepatitis C virus

Abstract

The ability of antigens to elicit immune responses depends upon their initial recognition, uptake, processing and presentation by dendritic cells. This fact has been recognized by many workers and dendritic cells are now regarded as natural 'adjuvants' in the business of vaccine design. One way of persuading dendritic cells to become interested in foreign material is to decorate it with lipid moieties found in bacteria. This approach has been used in the context of synthetic peptide-based immunogens and depending on the nature of the epitopes included, can provide highly immunogenic structures capable of eliciting antibody or cytotoxic T cell responses. In this paper we describe the results ..
