1 Cholesterol up-regulates neuronal G protein-gated inwardly rectifying potassium (GIRK) channel activity in the hippocampus. Cholesterol potassium inwardly rectifying channel subfamily J member 3 L homeolog Xenopus laevis
2 Yet, the effect of cholesterol on G protein-gated inwardly rectifying potassium (GIRK) channels expressed in the brain is unknown. Cholesterol potassium inwardly rectifying channel subfamily J member 3 L homeolog Xenopus laevis
3 We also demonstrate that cholesterol plays a critical role in modulating neuronal GIRK currents. Cholesterol potassium inwardly rectifying channel subfamily J member 3 L homeolog Xenopus laevis
4 In accordance, elevated currents upon cholesterol enrichment were also observed in Xenopus oocytes expressing GIRK2 channels, the primary GIRK subunit expressed in the brain. Cholesterol potassium inwardly rectifying channel subfamily J member 3 L homeolog Xenopus laevis
5 These findings establish that cholesterol plays a critical role in modulating GIRK activity in the brain. Cholesterol potassium inwardly rectifying channel subfamily J member 3 L homeolog Xenopus laevis
6 Because up-regulation of GIRK function can reduce neuronal activity, our findings may lead to novel approaches for prevention and therapy of cholesterol-driven neurodegenerative disease. Cholesterol potassium inwardly rectifying channel subfamily J member 3 L homeolog Xenopus laevis
