A visual approach for inducing dolichoectasia in mice to model large vessel-mediated cerebrovascular dysfunction(대혈관 매개 뇌혈관 기능 장애를 모델링하기 위해 마우스에서 백우절충증을 유도하기 위한 시각적 접근법)

Executive Industry Relevance

Modeling sustained large vessel dolichoectasia in transgenic mice enables mechanistic interrogation of cerebrovascular dysfunction relevant to Alzheimer's disease and vascular dementia. This approach supports predictive confidence in linking vascular pathology to neurodegenerative outcomes, informing early-stage target validation and risk-adjusted portfolio decisions. The method's reproducibility and extended vessel dilatation window enhance its translational value for preclinical vascular research.
