Heat shock proteins in health and disease.
Heat shock proteins are among the most abundant proteins of the biosphere. They not only play a major role under stress conditions but also perform important physiological functions. The present review summarizes the potential contribution of heat shock proteins to health and disease related to immunity: their contribution to antibody assembly and antigen presentation; their role in host cell protection against "immune stress"; their participation in tumor surveillance; their relation to gamma/delta T-cell recognition; their function as microbial virulence factors; their dominant antigenicity for the immune response against microbial pathogens; and their possible role as autoantigens. The findings summarized here illustrate the marked liaison between heat shock proteins and the immune response, which may be both beneficial and detrimental to the host.
