Neuroaktivni steroid
Neuroaktivni steroidi, takođe poznati kao neurosteroidi, su endogeni steroidi koji brzo menjaju neuronsku ekscitabilnost putem interakcija sa ligandom kontrolisanih jonskih kanala i drugih receptora na ćelijskoj površini.[1][2] Termin neurosteroid koji je formirao francuski fiziolog Étienne-Émile Baulieu obuhvata steroide koji su sintetisani u mozgu.[3] U kontrastu s njima neuroaktivni steroid se odnose na steroide koje sintetišu endokrine žlezde i koji dospevaju do mozga putem krvotoka.[4] Osim njihovih dejstava na neuronske membranske receptore, neki od ovih steroida modu da utiču na izražvanje gena putem nuklearnih steroidnih hormonskih receptora. Neurosteroidi imaju širok opseg potencijalnih kliničkih primena od sedacije do tretmana epilepsije[5] i traumatičnih moždanih povreda.[6][7] Ganaksolon, sintetički analog endogenog neurosteroida alopregnanolona, se ispituje za moguću primenu u tretmanu epilepsije.[8]
