Gene that boosts Alzheimer’s risk might protect against it too
Carrying certain genetic versions of apolipoprotein E is a major risk factor for Alzheimer’s disease. A new study looks at the effects of different types of APOE on the major markers of Alzheimer’s in mice and shows that all forms are not equal.
