Photothrombotic 기술을 이용하여 외접 캡슐 경색 모델링

Executive Industry Relevance

This photothrombotic technique enables precise modeling of white matter stroke by selectively targeting the internal capsule while sparing adjacent gray matter. The resulting circumscribed capsular infarct produces persistent motor deficits, providing a disease-relevant system for mechanistic de-risking of neurotherapeutic candidates. The model supports target validation and preclinical assessment of interventions aimed at white matter pathology, addressing a critical gap in stroke research.
