Houston [US], October 5 (ANI): New research from Houston Methodist reveals how obesity may directly drive Alzheimer's disease.

Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can carry harmful signals that accelerate the buildup of amyloid-b plaques in the brain.

These vesicles even cross the blood-brain barrier, making them powerful but dangerous connectors between body fat and brain health.

The study, "Decoding Adipose-Brain Crosstalk: Distinct Lipid Cargo in Human Adipose-Derived Extracellular Vesicles Modulates Amyloid Aggregation in Alzheimer's Disease," was published on October 2 in Alzheimer's & Dementia: The Journal of the Alzheimer's Association.

It explores the link between obesity, which affects about 40% of the U.S populatio
