阿尔茨海默病的特征是淀粉样斑块、神经原纤维缠结、神经胶质活化和神经变性。在小鼠模型中,小胶质细胞的炎症激活加速了tau的病理。趋化因子fractalkine是一种内源性神经元调节剂,可抑制小胶质细胞的激活。fractalkine受体缺失小鼠的实验表明,fractalkine信号传导减少tau病理,但加剧淀粉样蛋白病理。与这一结果一致,我们在这里报告了使用腺相关病毒载体过表达可溶性fractalkine可显著降低tau沉积rTg4510小鼠模型中的tau病理学。此外,这种治疗减少了小胶质细胞的激活,似乎可以防止在该模型中正常发现的神经变性。然而,与fractalkine受体缺失小鼠的研究相反,APP/PS1模型中的平行研究发现fractalkine信号传导增加对淀粉样蛋白沉积没有影响。这些数据表明,fractalkine受体的激动作用可能是牛头病(包括与淀粉样蛋白沉积相关的牛头病)治疗干预的一个极好的靶点。
Alzheimer’s disease is characterized by amyloid plaques, neurofibrillary tangles, glial activation, and neurodegeneration. In mouse models, inflammatory activation of microglia accelerates tau pathology. The chemokine fractalkine serves as an endogenous neuronal modulator to quell microglial activation. Experiments with fractalkine receptor null mice suggest that fractalkine signaling diminishes tau pathology, but exacerbates amyloid pathology. Consistent with this outcome, we report here that soluble fractalkine overexpression using adeno-associated viral vectors significantly reduced tau pathology in the rTg4510 mouse model of tau deposition. Furthermore, this treatment reduced microglial activation and appeared to prevent neurodegeneration normally found in this model. However, in contrast to studies with fractalkine receptor null mice, parallel studies in an APP/PS1 model found no effect of increased fractalkine signaling on amyloid deposition. These data argue that agonism at fractalkine receptors might be an excellent target for therapeutic intervention in tauopathies, including those associated with amyloid deposition.
