Outline of Final Research Achievements

(1) Deficiency of E4BP4 reduced the inflammatory cytokines and suppressed neointimal formation after injury. The present study is the first to demonstrate that E4BP4 plays an important role in the increase of neointimal formation after injury in vivo, thus suggesting that E4BP4 inhibition may represent a useful strategy to inhibit vascular inflammation. (2) Inhibition of interleukin-1 decreased Angiotensin II-induced hypertension and renal damage in mice, suggesting suppression of IL-1 may provide an additional strategy to protect against renal damage in hypertensive patients.

Academic Significance and Societal Importance of the Research Achievements

我々は今回2つのことなる実験系で結果を出すことができた。
(1)時計遺伝子のE4BP4の阻害が血管の炎症を抑制する有用な戦略である可能性を示した。(2)IL-1の抑制がAngII誘発高血圧および腎障害を減少させたことより、IL-1の抑制が高血圧患者における腎障害進行を防ぐ新たな治療法となることを実証した。
以上が成果が新規治療法につながれば、心血管発症予防や透析患者減少をもたらし、医療費削減につながるため社会的意義は大きいと考える。
