How the APOE4 Gene May Speed Up Tau Tangles in Alzheimer's
This study points to a new drug target, but offers no direct lifestyle action yet.
In mouse and neuron experiments, researchers found a special proteasome on neurons that normally clears out tau protein before it forms toxic tangles. People with the APOE4 gene (the biggest genetic risk factor for Alzheimer's) have less of this cleanup machinery, and levels also drop with age. This may explain why APOE4 carriers are more vulnerable to Alzheimer's pathology.
