Abstract

The high morbidity and mortality rate of ischemic stroke in humans has led to the development of numerous animal models that replicate human stroke to further understand the underlying pathophysiology and to explore potential therapeutic interventions. Although promising therapeutics have been identified using these animal models, with most undergoing significant testing in rodent models, the vast majority of these interventions have failed in human clinical trials. This failure of preclinical translation highlights the critical need for better therapeutic assessment in more clinically relevant ischemic stroke animal models. Large animal models such as non-human primates, sheep, pigs, and dogs are likely more predictive of human responses and outcomes due to brain anatomy and physiology that are more similar to humans-potentially making large animal testing a key step in the stroke therapy translational pipeline. The objective of this review is to highlight key characteristics that potentially make these gyrencephalic, large animal ischemic stroke models more predictive by comparing pathophysiological responses, tissue-level changes, and model limitations.

摘要

人类缺血性中风的高发病率和死亡率促使众多动物模型的开发,这些模型可复制人类中风情况,以进一步了解潜在的病理生理学并探索潜在的治疗干预措施。尽管利用这些动物模型已确定了有前景的治疗方法,且大多数在啮齿动物模型中进行了大量测试,但这些干预措施绝大多数在人类临床试验中失败了。临床前转化的这种失败凸显了在更具临床相关性的缺血性中风动物模型中进行更好治疗评估的迫切需求。由于大脑解剖结构和生理机能与人类更相似,非人类灵长类动物、绵羊、猪和狗等大型动物模型可能对人类反应和结果具有更强的预测性,这可能使大型动物测试成为中风治疗转化流程中的关键一步。本综述的目的是通过比较病理生理反应、组织水平变化和模型局限性,突出可能使这些脑回状大型动物缺血性中风模型更具预测性的关键特征。
