| Research Abstract |
In diabetic mellitus, inflammation is observed in the brain as well as the peripheral and contributes to the pathogenesis of diabetic cognitive dysfunction. This study aimed to clarify the involvement of thrombin-responsive brain pericytes in the propagation mechanism of inflammation from the peripheral to the brain. Increase the amount of thrombin was observed in the brain of high-fat diet induced obesity and glucose-intolerance model mouse. Further, thrombin-treated brain pericytes enhanced the permeability of the blood-brain barrier, and released matrix metalloproteinase-9. These results suggest that thrombin-responsive brain pericytes have an important role in the formation of brain inflammation in diabetic mellitus.
