Liver X receptor (LXR) α and β are nuclear receptors that are crucial for the regulation of carbohydrate and lipid metabolism. Activation of LXRs in the brain facilitates cholesterol clearance and improves cognitive deficits, thus they are considered as promising drug targets to treat diseases such as atherosclerosis and Alzheimer's disease. Nevertheless,(More)
Liver X receptors (LXR) are important transcription factors involved in the regulation of carbohydrate and lipid metabolism and are expressed in different brain areas. Recently we described that LXR expression in the hypothalamus is sensitive to serum levels of lipids and carbohydrates. Here, we further characterized the effects of glucose, insulin,(More)
Neuroactive steroids, like allopregnanolone (A) and pregnanolone (P), bind to specifics sites on the GABAA receptor complex and modulate receptor function. They are capable to inhibit or stimulate the binding of GABAA receptor-specific ligands, like t-butyl-bicyclophosphorothionate, flunitrazepam and muscimol. We have previously characterized a set of(More)
Allopregnanolone (A) and pregnanolone (P) are able to modify neural activities acting through the GABAA receptor complex. This capacity makes them useful as anticonvulsant, anxiolytic, or anti-stress compounds. In this study, the performance of seven synthetic steroids (SS) analogous of A or P containing an intramolecular oxygen bridge was evaluated using(More)
Compelling evidence shows that the offspring subjected to uncontrolled hyperlycemia during gestation display behavioral, neurochemical, and cellular abnormalities during adulthood. However, the molecular mechanisms underlying these defects remain elusive. Previous studies have shown an increased rate of apoptosis and a decreased index of neuronal(More)
UNLABELLED Perinatal asphyxia occurs in approximately 0.3% full-term newborn babies, and this percentage has not decreased despite medical advances. There are now evidences indicating that neurosteroids are important in neurodevelopment showing neuroprotective effects. We studied the potential protective effect of allopregnanolone (Allo) in vitro using(More)
