Fig. 1From: Peripheral apoE isoform levels in cognitively normal APOE ε3/ε4 individuals are associated with regional gray matter volume and cerebral glucose metabolismPlasma apoE levels. Plasma levels of total apoE, apoE3 and apoE4 isoforms in the total APOE ε3/ε4 cohort studied (n = 128) and in the imaged cohort (n = 25) (a). Correlation between plasma total apoE levels and the individual apoE3 (b) and apoE4 (c) isoform levels, and between plasma apoE3 and apoE4 isoform levels (d). apoE apolipoprotein EBack to article page
