Outline of Final Research Achievements

Based on photodynamic therapy (PDT), we studied the Infection control and developed a new treatment for pressure ulcer by promoting wound healing.
1. Study using subcutaneous soft tissue infection model mice: A) PDT conditions inducing maximization of treatment efficiency were found. B) Visualization of neutrophil kinetics after PDT was succeeded. C) Signal transduction related to neutrophil migration / accumulation was clarified. 2. We succeeded in promoting granulation and epithelialization by PDT on the skin defect model mice and clarified the conditions for controlling its effect. 3. Aiming at the construction of a next-generation homogeneous irradiation system that incorporates a feedback system that can correct light intensity unhomogenuity, we have developed basic technology for intensity unhomogenuity correction.

Academic Significance and Societal Importance of the Research Achievements

PDTを用いた感染症治療に関しては、これまで皮膚などの外表面における感染対策が中心であったが、本技術開発により皮膚のみならず皮下組織や軟部組織等の生体深部においても治療が可能となる。また、本研究での抗菌効果の実証は、薬剤耐性を示す菌に対するPDTによる感染制御効果の典型的事例を示すことになるだけでなく、PDTの持つ創傷治癒促進効果を利用した治療期間の短縮にもつながる技術となる。これらの技術開発は、褥瘡など難治性の病変に対しても朗報をもたらすことが期待できる。
