Avaliação dos efeitos neuroprotetores do pós-condicionamento ácido em um modelo de camundongo com isquemia cerebral

Executive Industry Relevance

Acidic postconditioning (APC) in a mouse model of cerebral ischemia provides a controlled system to interrogate neuroprotective mechanisms relevant to ischemic injury. This approach enables mechanistic de-risking of therapeutic hypotheses targeting excitotoxicity and oxidative stress, supporting early-stage target validation and predictive confidence for neuroprotection portfolios. The model's quantitative outputs inform risk-adjusted advancement decisions in CNS drug discovery.
