Selective modulators of α5-containing GABAA receptors and their therapeutic significance.
Abstract GABAA receptors containing the α5 subunit (α5GABAARs) are found mainly in the hippocampus where they mediate a tonic chloride leak current and contribute a slow component to GABAergic inhibitory synaptic currents. Their inhibitory effect on the excitability of hippocampal neurons at least partly explains why changes in the level of activity of α5GABAARs affect cognition, learning and memory. These receptors have been implicated as potential therapeutic targets for a range of clinical conditions including age-related dementia, stroke, schizophrenia, Down syndrome and anesthetic-induced amnesia. Accordin...

A review on the neuroprotective effect of berberine against chemotherapy-induced cognitive impairment
Curr Drug Targets. 2022 Mar 3. doi: 10.2174/1389450123666220303094752. Online ahead of print.ABSTRACTChemobrain is one of the major side effects of chemotherapy, despite increased research, the mechanisms underlying chemotherapy-induced cognitive changes remain unknown. Though, several possibly important candidate mechanisms have been identified and will be studied further in the future. Chemobrain is characterized by memory loss, cognitive impairment, difficulty in language, concentration, acceleration, and learning. The major characteristic of chemobrain is oxidative stress, mitochondrial dysfunction, immune dysregulatio...
