Outline of Research at the Start

創傷の難治化要因の一つに、加齢に伴う細胞老化により蓄積した老化細胞が、慢性炎症を誘発し創傷治癒を阻害することが挙げられる。これまでに、局所低周波振動刺激が慢性炎症を改善し創傷治癒を促進させ、それに先立ち老化マーカーの遺伝子発現が減弱していることを見出した。そこで局所低周波振動刺激が老化細胞を除去し、炎症を抑制することで創傷治癒が促進するのではないかと着想した。しかしこれまで、局所低周波振動などの物理的刺激による老化細胞除去の報告はなく、そのメカニズムや臨床適応のための至適な振動条件は明らかでない。そこで本課題では局所低周波振動刺激による老化細胞除去メカニズムおよび至適条件の解明に挑む。

Outline of Final Research Achievements

This study aimed to establish a novel care approach for preventing hard-to-heal wounds by elucidating the mechanisms and optimal conditions of senescent cell clearance induced by local low-frequency vibration (LLFV). We developed a wearable dressing and evaluated the effects of LLFV on senescent cell removal, suppression of cellular senescence, and promotion of wound healing in a full-thickness wound model using hyperglycemic rats. As a result, LLFV was shown to suppress the expression of senescence-associated markers in wound tissue, reduce the proportion of senescent cells in wound exudates, improve chronic inflammation, and enhance wound healing. These findings suggest the potential of LLFV as a physical senolytic strategy.

Academic Significance and Societal Importance of the Research Achievements

本研究では、難治性創傷の滲出液管理に使用するドレッシング材と振動機能を組み合わせウェアラブル化し、高血糖ラット全層欠損創に対するLLFVによって細胞老化抑制と創傷治癒促進効果を示した。従来のセノリティクス研究は内部臓器を標的としており、創傷に対する応用例は極めて少ない。そしてドレッシングタイプのセルフケアデバイスによるLLFVは、創部への直接的な物理的刺激を通じて細胞老化を抑制し創傷治癒を促進するという新しい概念の創出に寄与する。本研究は物理的セノリティクスによる難治化予防の可能性を見出し、新しい学理が形成されるとともに、ポストCOVID-19時代における在宅医療・ケアへの貢献が期待される。
