Amyloid-beta protein

Comparisons of a healthy brain and one with Alzheimer's

Neuron discovery could explain why some people don't get Alzheimer's

Some brains seem to defy Alzheimer's. This phenomenon, known as cognitive resilience, is one of the most intriguing puzzles in neuroscience today.

Amyloid plaques that misfold and form oligomers kill brain cells leading to cognitive decline. Scientists find that a protein in some cancers helps the brain get rid of them

Alzheimer's & Dementia

Surprising way cancer cells clear problematic proteins in the brain

For some time, we've known that it's rare to see people with both cancer and Alzheimer's diseases. Now, scientists believe they may have found why, discovering a molecule in cancer cells that clears problem proteins from the brain.

Amyloid-beta, the protein associated with neuron destruction in Alzheimer's disease, boosts the immune system's cancer-fighting ability

Notorious Alzheimer’s protein also supercharges cells against cancer

A protein notorious for its role in Alzheimer’s disease may hold the key to supercharging the aging immune system. Scientists showed that a byproduct of amyloid-beta rejuvenates T cells, boosting their tumor-fighting power and slashing cancer risk.
