Old template overwrites new template content test (VLDLs), which are essential for the transport of dietary lipids and endogenous lipids throughout the body. ApoE exists in three major isoforms—ApoE2, ApoE3, and ApoE4—each with distinct genetic and functional characteristics. ApoE3 is considered the most common and neutral form, while ApoE4 is associated with an increased risk of developing late-onset Alzheimer's disease and cardiovascular diseases due to its role in promoting amyloid-beta aggregation and impaired lipid clearance. In the brain, ApoE is involved in synaptic function, neuronal repair, and neuroinflammation, highlighting its importance in maintaining central nervous system health.
