Prenatal exposure to ethanol can cause serious damage to the developing central nervous system. Both in vivo and in vitro studies demonstrate the vulnerability of the developing serotonergic system to the damaging effects of ethanol. However, treatment with a serotonin-1A (5-HT1A) agonist prevents the ethanol-associated apoptosis in developing 5-HT neurons. One mechanism by which 5-HT1A agonists exert their neuroprotective effects appears to involve activation of the phosphatidylinositol 3'kinase (PI-3K) pro-survival pathway and activation of NF-κB dependent anti-apoptotic genes. Additional NF-κB dependent genes might also be involved with the neuroprotective effects of ipsapirone.
There is also considerable evidence that ethanol augments …
