damage over time and mitochondrial defects have been frequently reported in Parkinson's
disease (PD) patients. However, the causal contribution of adult-onset mitochondrial
dysfunction to PD remains uncertain. Here, we developed a mouse model lacking Mitofusin
2 (MFN2), a key regulator of mitochondrial network homeostasis, in adult midbrain DA
neurons. The knockout mice develop severe and progressive DA neuron-specific …
