title: Effect of recombinant heat shock protein 70 of mycobacterial origin on cytotoxic activity and immunophenotype of human peripheral blood mononuclear leukocytes.
abstract: Recombinant heat shock protein of mycobacterial origin with a molecular weight 70 kDa in concentration 0.1 microg/ml in vitro activates cytotoxic activity of mononuclear lymphocytes from peripheral blood of healthy donors against K-562 human erythroblastic leukemia cells sensitive to natural killers. In other concentrations (1.0 microg/ml and 10 microg/ml) this heat shock protein did not significantly affect functional activity of mononuclear leukocytes. Expression of CD4, CD25, CD16 and CD56 on membrane of mononuclear leukocytes was also studied.
