Effects of pentylenetetrazol on GABA receptors expressed in oocytes of Xenopus laevis: extra- and intracellular sites of action.

abstract：:Brain-derived neurotrophic factor (BDNF) and insulin promote the survival of 6-7 day old post-natal rat cerebellar granule cells. Previous studies using the PI3 kinase inhibitor, wortmannin and the over-expression of protein kinase B (PKB) have indicated that both PI3 kinase and PKB activation are central for insulin-...
