Only the combination treatment lower blood pressure and improved salt-sensitivity. The combination treatment significantly ameliorated glomerulosclerosis, and reduced cardiomyocyte hypertrophy and perivascular fibrosis. Angiotensin II type 1 receptor (AT1R) protein expression level in the kidney was remarkably suppressed in the combination treatment group compared to the other high salt diet groups. The protein expression level of Na+/H+ exchanger isoform 3 and Na+-K+-Cl- cotransporter 2 were significantly decreased with losartan alone and combination with ipragliflozin., 2018年度~2020年度科学研究費補助金(基盤研究(C))研究成果報告書, 18K08101}, title = {食塩感受性高血圧モデルにおけるSGLT2阻害の心不全進展抑制効果の検討}, year = {2021}, yomi = {ドヒ, カオル and イトウ, マサアキ and オカモト, リュウジ and カタヤマ, カン} }
