Ectopic lipid accumulation: potential role in tubular injury and inflammation in diabetic kidney disease

Emerging studies suggest that lipid accumulates in the kidneys during diabetic kidney disease (DKD). However, the correlation between ectopic lipid accumulation with tubular damage has not been thoroughly elucidated to date. Using Oil Red staining, lipid accumulation was observed in the kidneys of type 2 DKD patients (classes II–III) and db/db mice compared with the control and was predominantly located in the proximal tubular compartment....
