Previous studies have shown significant changes in amyloid-β (Aβ) transport across the blood-brain barrier (BBB) under diabetic conditions with hypoinsulinemia, which is involved in diabetes-associated cognitive impairment. Present study employed db/db mice with hyperinsulinemia to investigate changes in Aβ transport across the BBB, hippocampal synaptic(More)
Neurons in the dorsal spinal cord play important roles in nociception and pain. These neurons receive input from peripheral sensory neurons and then transmit the signals to the brain, as well as receive and integrate descending control signals from the brain. Many molecules important for pain transmission have been demonstrated to be localized to the dorsal(More)
The discovery of a novel series of NR2B subtype selective N-methyl-d-aspartate (NMDA) antagonists is reported. Initial optimization of a high-throughput screening lead afforded an aminopyridine derivative 13 with significant NR2B antagonist potency but limited selectivity over hERG-channel and other off-target activities. Further structure-activity studies(More)
BACKGROUND AND PURPOSE There is emerging evidence suggesting that abnormal transport of amyloid-β (Aβ) across the blood-brain barrier (BBB) is involved in diabetes-associated cognitive decline. We investigated whether PPARγ agonists restore Aβ transport across the BBB and hippocampal plasticity in db/db mice. EXPERIMENTAL APPROACH Efflux and influx of Aβ(More)
Amyloid-β deposition is thought to be associated with memory deficits, neuroinflammation, apoptotic responses, and progressive neuronal death manifested in Alzheimer’s disease. Peroxisome proliferator-activated receptor δ (PPARδ) is a transcription factor with potent anti-inflammatory effect. In the current study, the effect of GW0742, a selective PPARδ(More)
