- 腎臓科
- 分子生物学
- バイオ情報学
背景:
- 腎不全再注射 (I/ R) 損傷は腎移植における重大な合併症であり,急性腎損傷 (AKI) に繋がります.
- I/R-AKIの現在の治療戦略は限られており,新しい分子標的と診断ツールの特定が必要である.
研究 の 目的:
- I/R誘発性AKI (I/R-AKI) の基礎となる分子メカニズムを単細胞レベルで解明する.
- 潜在的治療標的を特定し,I/R-AKIの診断モデルを開発する.
- I/R-AKIを緩和する薬剤の有効性を評価する.

- I/R-AKIにおける重要な遺伝子を特定するための単細胞データのバイオ情報分析.
- I/R-AKIの診断モデルの開発と検証
- I/RマウスモデルとヒトAKIサンプルにおける免疫光,ウェスタン・ブロッティング,免疫組織化学,伝送電子顕微鏡を用いた実験的検証.
- ADAMTS1発現とI/ R- AKI病理に対するトログリタゾンの影響の評価
主要な成果:
- I/R-AKIの強力な診断モデルが開発され,検証されました.
- ADAMTS1は腎臓のI/ R- AKIのプロモーターとして識別され,腎臓管状上皮細胞において著しく上調された.
- ミトコンドリア経路によるアポトーシスは,I/ R損傷の進行における重要な要因として確認された.
- トログリタゾンによるADAMTS1の抑制は,I/ R- AKIマウスモデルにおける機能的および組織学的損傷を著しく減少させた.

Acute Kidney Injury I: Introduction
72
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
