Cholesterol manufactured in the brain appears to play a key role in the development of Alzheimer’s disease, new research indicates. Scientists from the University of Virginia School of Medicine and ...

Medically reviewed by Christopher Lee, MD High cholesterol refers to an elevated level of a fat called low-density lipoprotein (LDL) in the bloodstream. Over many years, high levels of LDL increase ...

The active genes in the body have to be copied, or transcribed into RNA molecules, which are then processed in a variety of ways before being translated into proteins. One processing mechanism ...

A new study led by researchers from VIB and KU Leuven shows that immune cells called microglia can actively promote the formation of plaques in Alzheimer's disease, challenging the long-standing view ...

Researchers at Kindai University found that the amino acid L-arginine, costing about $2 a month, reduced amyloid-beta plaques in both fruit fly and mouse Alzheimer’s models. The orally administered ...

A new PET tracer proved for the first time that it can be used to identify brain activity involved in the formation of plaque in people with cognitive impairment and Alzheimer’s disease, according to ...

After studying 140,000 versions of the Aβ42 peptide, scientists identified some of the earliest molecular interactions that drive the formation of harmful amyloid protein aggregates found in Alzheimer ...

Plaque formation in the arteries carrying blood to the head and neck is a serious medical problem, potentially leading to strokes and heart attacks. In Physics of Fluids, by AIP Publishing, engineers ...

The new findings offer important insights into how and why the plaques form and may explain why genes associated with cholesterol have been linked to increased risk for Alzheimer's. Cholesterol ...
