Amyloid-beta protein

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.

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.
