Outline of Final Research Achievements

1. A search for novel therapeutic biomarkers in a model of SGLT inhibitor (Phlorizin) treatment for early onset of type 2 diabetes in mice(High Fat Induced Obesity C57BL/6J mouse) resulted in the C22 to C24 long-chain fatty acids of sphingomyelin as candidates. 2. Social defeat stress model produces depressive symptoms in the corpus callosum of C57BL6 mice. Demyelination of myelinated axons occurs with activation of microglia. Administration of an inhibitor of IL-1b, which suppresses microglial activity, improved depression-like symptoms.
3.A mathematical model was developed to calculate the flow rate and velocity of the original urine at the glomerular nephron and collecting ducts.

Academic Significance and Societal Importance of the Research Achievements

2型糖尿病性腎障害がSGLT阻害剤により改善されることは知られているが、今まで治療に対する反応性を正確に把握する治療バイオマーカーが十分に分かったいなかった。尿中のスフィンゴミエリンは比較的安定であり、脂肪酸伸長と脂質代謝の長期的な変化を負うことができると考える。SGLT阻害剤投与により尿中に排泄されることが明らかになったため、腎臓組織の脂肪酸代謝と腎機能保護作用について詳細に検討できる。また、社会的なストレスにより脳のミクログリアが活性化し、脳梁の脱髄を引き起こすことが分かり、ミクログリアをIL-1b阻害剤がうつ病の新規治療薬として検討される。
