In search of a possible cure for Alzheimer’s disease (AD), scientists have found out the molecular structure of a type of protein called beta amyloid that accumulates within brain cells, eventually ...

An unusual protein structure known as a "rippled beta sheet," first predicted in 1953, has now been created in the laboratory and characterized in detail using x-ray crystallography. The new findings, ...

Protein fibril self-assembly is a universal transition implicated in neurodegenerative diseases. Although fibril structure/growth are well characterized, fibril nucleation is poorly understood. Here, ...

Understanding the process of fibril formation and, more specifically, the toxic beta amyloid (Aβ) protein fragments, is fundamental to advancing treatments for Alzheimer’s disease. New research ...

The beta cells of the pancreas are responsible for releasing the hormone insulin, which is vital for the absorption of glucose from the bloodstream. Various factors can impair the ability of these ...

The chemical interactions that give proteins their shape may be weaker and more numerous than previously recognized. Chemists modeled the building blocks of the protein structure that causes Alzheimer ...

Researchers have developed a microscopy technique to visualize amyloid beta’s underlying structure, which could yield new insights into Alzheimer’s disease. As the prevalence of Alzheimer’s rises, ...
