Heat shock proteins (hsps) assist the assembly, folding and translocat
ion of other proteins, and apparently have a role in protecting cells
against injuries and other types of stress. In addition, hsps are freq
uently recognized by the immune system as predominant antigens during
infections and during the progression of certain autoimmune diseases a
nd, thus, might provide a novel route for the development of immunothe
rapeutics. This review focuses on applications for hsps in health and
disease, and discusses the pros and cons of considering them as target
s for the development of therapeutics/pharmaceuticals.
