PG - 1-9 LID - S1044-7431(14)00007-4 [pii] LID - 10.1016/j.mcn.2014.01.006 [doi] AB - We investigated the effects of cilostazol, a selective inhibitor of phosphodiesterase 3, on blood-brain barrier (BBB) integrity against ischemia-reperfusion injury enhanced by advanced glycation endproducts (AGEs). We used in vitro BBB models with primarily cultured BBB-related cells from rats (brain capillary endothelial cells, astrocytes and pericytes), and subjected cells to either normoxia or 3-h oxygen glucose deprivation (OGD)/24-h reoxygenation with or without AGEs. Treatment of AGEs did not affect the transendothelial electrical resistance (TEER) in the BBB model under normoxia, but there was a significant decrease in TEER under 3-h OGD/24-h reoxygenation conditions with AGEs. Cilostazol inhibited decreases in TEER induced by 3-h OGD/24-h reoxygenation with AGEs. Immunocytochemical and Western blot analyses showed that AGEs reduced the expression of claudin-5, the main functional protein of tight junctions (TJs). In contrast, cilostazol increased the expression of claudin-5 under 3-h OGD/24-h reoxygenation with AGEs. Furthermore, while AGEs increased the production of extracellular transforming growth factor (TGF)-beta1, cilostazol inhibited the production of extracellular TGF-beta1 and restored the integrity of TJs. Thus, we found that AGEs enhanced ischemia-reperfusion injury, which mainly included decreases in the expression of proteins comprising TJs through the production of TGF-beta1. Cilostazol appeared to limit ischemia-reperfusion injury with AGEs by improving the TJ proteins and inhibiting TGF-beta1 signaling. CI - Copyright (c) 2014 Elsevier Inc. All rights reserved.
