Peroxisome Proliferator-Activated Receptor-γ Agonists: Potential Therapeutics for Neuropathology Associated with Fetal Alcohol Spectrum Disorders.

Fetal alcohol spectrum disorders (FASD) result from fetal exposure to alcohol during pregnancy. These disorders present a variety of sequelae including involvement of the central nervous system (CNS) with lasting impact on cognitive function and behavior. FASD occur at an alarming rate and have significant personal and societal impact. There are currently no effective treatments for FASD. Recent studies demonstrate that ethanol induces potent neuroinflammation in many regions of the developing brain. Furthermore, anti-inflammatory agents such as peroxisome proliferator-activated receptor (PPAR)-γ agonists suppress ethanol-induced neuroinflammation and neurodegeneration. This suggests that anti-inflammatory agents may be effective in treatment of FASD. Future studies designed to determine the specific mechanisms by which alcohol induces neuroinflammation in the developing CNS may lead to targeted therapies for FASD.
