title: Induction of heat shock protein 70 genes in human lymphocytes during fever therapy.
abstract: The induction of heat shock protein 70 (HSP70) genes has been studied in peripheral blood mononuclear cells of individuals undergoing fever therapy because of metastatic malignant melanoma. Induction of HSP70 was assessed at the protein level by metabolic labelling or, for the HLA-linked HSP70-1 and HSP70-2 genes, at the RNA level by in situ hybridization. However, de novo expression of HSP70 could be observed during fever (usually above 39 degrees C) in only about half of the cases. No simple threshold model for inducibility of HSP70 in vivo could be applied. The HSP70-1 gene was induced more easily than HSP70-2. Thus, heat-inducible HSP70 genes, including HLA-linked HSP70 genes, become expressed in human lymphocytes during fever, but not regularly.
