We found that CNS-directed expression of interferon-γ (IFN-γ) resulted in basal ganglia calcification, reminiscent of human idiopathic basal ganglia calcification (IBGC), and nigrostriatal degeneration. Our results indicate that IFN-γ mediates age-progressive nigrostriatal degeneration in the absence of exogenous stressors. Further study of this model may provide insight into selective nigrostriatal degeneration in human IBGC and other Parkinson syndromes.
我们发现,干扰素-γ(IFN-γ)在中枢神经系统中的表达导致基底节钙化,使人联想到特发性基底节钙化(IBGC)和黑质纹状体变性。我们的结果表明,IFN-γ在没有外源应激的情况下介导年龄进展性黑质纹状体变性。对该模型的进一步研究可能为人类 IBGC 和其他帕金森综合征中选择性黑质纹状体变性提供深入了解。
