DPP-4 Inhibitor and Sulfonylurea Differentially Reverse Type 2 Diabetes–Induced Blood–Brain Barrier Leakage and Normalize Capillary Pericyte Coverage
Microvascular pathology in the brain is one of the suggested mechanisms underlying the increased incidence and progression of neurodegenerative diseases in people with type 2 diabetes (T2D). Although accumulating data suggest a neuroprotective effect of antidiabetics, the underlying mechanisms are unclear. Here, we investigated whether two clinically used antidiabetics, the dipeptidyl pep-tidase-4
