ApoE2

ApoE2 is a variant of the apolipoprotein E (ApoE) protein involved in lipid metabolism, which means it helps transport fats in the bloodstream. ApoE is crucial for brain health and plays a role in repairing neurons and maintaining cholesterol levels. The ApoE gene has several variants, including E2, E3, and E4. While ApoE2 is less common, research suggests it may offer some protective effects against neurodegenerative diseases, such as Alzheimer’s, compared to the more common E4 variant, which is linked to a higher risk of these conditions. Overall, ApoE2 may contribute to better brain health.
