APOE and lipoprotein glomerulopathy: Glomeruli cross-sectional area (9959 ± 1083 μm2) and number (24.8 ± 4.5) increased in apoE-/-/LDL-/- double knockout mice compared to controls (3533 ± 398 μm2; 17.6 ± 3, respectively), whereas 41% of the total number of glomeruli showed evidence for lipoprotein associated glomerulopathy (LPG).
