Heat Shock Protein Vaccines: From Bench to Bedside

Abstract

Heat shock proteins (HSPs) are immunogenic, with the specificity of the immune response provided by the peptides that they chaperone. Binding of cell surface receptors by HSPs is central to the elicitation of the innate and adaptive immune responses obtained after vaccination and also plays a physiologic role in cross-priming. These effects of HSPs have been exploited in prophylaxis and therapy of cancer and infectious disease. The data obtained from murine studies have been translated into ongoing clinical trials of cancer of which the most recent results are provided here.
