Impaired inducibility of heat shock protein 70 in peripheral blood lymphocytes of patients with severe sepsis

Abstract

Inducibility of ex vivo heat shock protein 70 was impaired in peripheral blood lymphocytes of patients with severe sepsis. The impaired expression of the potentially protective heat shock protein 70 may contribute in vivo to immune dysfunction, because intact functioning of T and B lymphocyte responses is of central importance in resisting infection in severe sepsis. Monitoring of inducible heat shock protein 70 in peripheral blood lymphocytes may contribute to the evaluation of the immune consequences of severe sepsis.
