'Magic number' 695 opens up new areas for Alzheimer's research
Alzheimer's disease is widely believed to be caused by the gradual accumulation in the brain of amyloid-beta peptide which is toxic to nerve cells. Amyloid beta peptide is formed from a protein known as APP, which is found ...

Protein inhibitor helps rid brain of toxic tau protein
Inhibiting the protein Hsp70 rapidly reduces brain levels of tau, a protein associated with Alzheimer's disease when it builds up abnormally inside nerve cells affecting memory, neuroscientists at the University ...

On...off...on...off... The circuitry of insulin-releasing cells
A myriad of inputs can indicate a body's health bombard pancreatic beta cells continuously, and these cells must consider all signals and "decide" when and how much insulin to release to maintain balance in blood sugar, for ...

Modulating a protein in the brain could help control Alzheimer's disease
A protein known to exist in the brain for more than 30 years, called 5-lipoxygenase, has been found to play a regulatory role in the formation of the amyloid beta in the brain, the major component of plaques implicated in ...

Variant form of amyloid beta hinders amyloidogenesis, development of Alzheimer's disease
Alzheimer's disease causes misfolding and aggregation of a protein fragment known as amyloid beta and its deposition as plaques in the brain. This process triggers a cascade of event that leads to neurodegeneration. A new ...
