Charybdotoxin inhibits proliferation and interleukin 2 production in human peripheral blood lymphocytes.

We demonstrate that blockade of the lymphocyte voltage-gated K+ channel by charybdotoxin (CTX) inhibits lymphocyte mitogenesis. Charybdotoxin blocks conductance with a Ki of 0.3 nM and inhibits mitogen- and antigen-stimulated proliferation with a Ki of 0.5 nM. As opposed to the other blockers of the lymphocyte K+ channel, the inhibition of mitogenesis by CTX can be overcome selectively by exoge...

Effects of Gamma Irradiation on Proliferation and IL-5 Production of Peripheral Blood Lymphocytes

Gamma irradiation is routinely used for suppression of lymphocyte function in transfusion and transplantation procedures. In recent years, some investigators focused on the effects of ionizing radiation on special aspects of lymphocyte function and considered the possibility of its clinical application for treatment of some immunological disorders. In this study, we evaluated the effects of fiv...

Effects of 35 Hz, 2 mT Magnetic Field on Peripheral Blood Lymphocytes of Human In Vitro and Rat In Vivo

In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...

Interleukin-8-stimulated polyphosphoinositide hydrolysis in human peripheral blood lymphocytes.

We have attempted to provide evidence for the production of inositol phosphate (IP) metabolites as an indication of specific receptor-mediated signal transduction in human peripheral blood lymphocytes (PBL) in response to interleukin-8 (IL-8). IP metabolites were measured, after loading of PBL with [3H]-D-myo-inositol, by anion exchange high-performance liquid chromatography (HPLC) and liquid s...

Interleukin 2 production by peripheral blood lymphocytes in allograft recipients during acute rejection episodes.

In this study we investigate the relationship between the Interleukin 2 (IL-2) yield produced by kidney allograft recipient's peripheral blood lymphocytes (PBL) under lectin stimulation and the occurrence of acute rejection episodes. PBL were harvested prospectively before grafting, after grafting in steady-state period, and at the onset of acute rejection episodes. In addition, we tested retro...
