| Research Abstract |
I investigated the molecular mechanism of regulation of TASK1 channels in endocrine cells. Pharmacological and molecular biological analyses showed that TASK1 channels are regulated by the clathrin-dependent endocytosis in NGF-stimulated adrenal medullary and PC12 cells. Furthermore, it was suggested that NGF-induced endocytosis of TASK1 channels is regulated by its posttranslational modification through activation of Src and the direct or indirect effects of activation of both PLCγand PI3 kinase.
