Cím:[Béta]-scorpion toxin 2 from Centruroides noxius blocks voltage-gated K+ channels in human lymphocytes / Gaspar R., Bene L., Damjanovich S., Munoz-Garay C., Calderon-Aranda E. S., Possani L. D.
Dátum:1995
ISSN:0006-291X
Megjegyzések:Using the patch-clamp technique, we determined that beta-scorpion toxin 2 from Centruroides noxius Hoffmann decreased whole-cell n-type K+ currents in human peripheral blood lymphocytes, with a half blocking concentration of approx. 5 microM. Toxin-2-accelerated inactivation, however, did not influence the kinetics of activation of the K+ conductance. The percentage increase in K+ channel inactivation rate and the degree of drug-induced block was independent of membrane potential. K+ channel block by Toxin 2 was instantaneous, not removable by washing with drug free extracellular solution. However, 10 mg/ml BSA in the bath lifted the toxin-induced block almost instantaneously and completely. Flow cytometric membrane potential measurements with the oxonol dye showed that Toxin 2 depolarizes human lymphocytes in concert with its K+ channel blocking effect.
