Disruption of sphingolipid metabolism promotes tau seeding through endolysosomal membrane rigidification and rupture

2 weeks 1 day ago
Endolysosomal dysfunction is a hallmark of Alzheimer's disease and related tauopathies, yet underlying mechanisms remain poorly understood. This study investigates the role of sphingolipid metabolism in maintaining endolysosomal membrane integrity and its impact on tau aggregation and toxicity in Caenorhabditis elegans and human cell culture models. Fluorescence recovery after photobleaching and C-Laurdan dye imaging revealed that silencing sphingolipid metabolism genes reduced endolysosomal...

What you eat before age 2 may affect your health 70 years later

Britain’s postwar sugar rationing created a rare natural experiment that let researchers examine how early sugar exposure might affect health decades later. People who experienced more rationing during their first 1,000 days had lower rates of several cancers and showed signs of slower biological aging. They were also still eating less sugar and maintaining healthier diets around age 50.
