The image shows the substantia nigra of a wildtype mouse 3 months following the injection of a-syn fibrils. The red represents the misfolded form of a-syn and reveals its accumulation as inclusions in dopamine neurons that are labeled green. This pathology is accompanied by a progressive loss of motor function in these fibril-inoculated animals.
