Description

The abstract shows ApoE4 diminishes the efficiency of fatty acid transport from neuronal lipid droplets to astrocytes, but the underlying molecular mechanisms are not explained. Understanding this transport disruption is critical since it appears to be a key step in ApoE4-mediated metabolic dysfunction.
