阿尔茨海默病(AD)是一种没有有效治疗方法的毁灭性疾病,啮齿动物中有希望的发现未能转化为患者的成功疗法。针对脆弱的内嗅皮层(ERC),恒河猴在左半球接受两次表达双tau突变(AAV-P301 L/S320 F)的腺相关病毒注射,并在右ERC中接受对照AAV-绿色荧光蛋白。未注射的年龄匹配猴作为额外对照。在3个月内,我们观察到错误折叠的tau蛋白传播的证据,类似于假设在人类中发生的情况。人4 R-tau的病毒递送也通过容许模板化结合猴3R-tau。Tau扩散伴随着由TREM 2+小胶质细胞驱动的强烈的神经炎症反应,在脑脊液和血浆中具有炎症和神经元损失的生物标志物。这些结果突出了灵长类动物模型中tau接种和传播的初始阶段,这是开发AD新疗法的更强大的翻译方法。
Alzheimer's disease (AD) is a devastating condition with no effective treatments, with promising findings in rodents failing to translate into successful therapies for patients. Targeting the vulnerable entorhinal cortex (ERC), rhesus monkeys received two injections of an adeno‐associated virus expressing a double tau mutation (AAV‐P301L/S320F) in the left hemisphere, and control AAV‐green fluorescent protein in the right ERC. Noninjected aged‐matched monkeys served as additional controls. Within 3 months we observed evidence of misfolded tau propagation, similar to what is hypothesized to occur in humans. Viral delivery of human 4R‐tau also coaptates monkey 3R‐tau via permissive templating. Tau spreading is accompanied by robust neuroinflammatory response driven by TREM2+ microglia, with biomarkers of inflammation and neuronal loss in the cerebrospinal fluid and plasma. These results highlight the initial stages of tau seeding and propagation in a primate model, a more powerful translational approach for the development of new therapies for AD.
