Suppression of a ligand operated membrane current by the epileptogenic agent pentylenetetrazol in oocytes of Xenopus laevis after injection of rat brain RNA.
???displayArticle.abstract???
The effects of the epileptogenic substance pentylenetetrazol (PTZ) on ligand operated membrane channels were studied. For this purpose serotonin (5-HT) sensitive channels were expressed in RNA injected oocytes of Xenopus laevis. With simultaneous application of both substances, the response to 5-HT was reduced and eventually abolished by PTZ with increasing concentrations (5-100 mM). A reduction of the 5-HT response also appeared when PTZ was applied in various intervals (15 and 240 s) before 5-HT. It may be assumed that PTZ produces a component of its epileptogenic effect by acting on ligand operated membrane channels.
