Outline of Final Research Achievements

The purpose of the study was to uncover the role of tenascin X in modulation of healing in mouse corneas subjected to epithelium debridement. Tenascin X protein was upregulated in the wounded wild-type (WT) corneal epithelium. Loss of tenascin X prolonged corneal epithelial wound healing and increased neutrophilic inflammatory response to debridement in mice. Although tenascin-deficient (KO) mice showed delayed regeneration of corneal sensory nerves, there was no difference in TRPV1, TRPV4, or TRPA1 expression between WT and KO mice. Tenascin X contributes to the control of neutrophil infiltration needed to support the regenerative response to injury and prevent the oxidative stress mediators from rising to cytotoxic levels.

Academic Significance and Societal Importance of the Research Achievements

テネイシンX欠失(KO)マウスでは好中球浸潤の制御が阻害されることで角膜上皮の治癒が遅延していた。またKOマウスでは角膜のコラーゲン線維の密度が低下しており、角膜上皮のみならず角膜実質の創傷治癒の遅延も確認された。これらの研究結果からテネイシンXを原因遺伝子としたエーラス・ダンロス症候群の患者では角膜外傷ひいては角膜切開での白内障手術時に創傷治癒が遅延する可能性が高いと考え感染対策あるいは創縫合など慎重に個別対応を検討する必要があると考えられた。
