Cholesterol and Signaling

Hemal discusses the critical role of cholesterol in maintaining membrane structure and signaling efficiency, particularly within lipid rafts. He highlights research linking cholesterol depletion to neurodegenerative diseases like Alzheimer's and ALS, emphasizing a novel protein that can restore membrane integrity and signaling. The conversation also touches on the potential of gene therapy to address these conditions, suggesting that proper lipid management could be key to reversing neurodegeneration.
