Fig. 2From: RETRACTED ARTICLE: Alpha-synuclein overexpression in the olfactory bulb initiates prodromal symptoms and pathology of Parkinson’s diseaseHm-α-syn was detected in brain regions beyond the OB 3 weeks after the AAV injection. Representative examples of high magnification images (scale bar: 20 μm) of the OB, the AON, the PPiri, the CPU, and the SN are shown. No GFP signal was found in the SN in the control animals. Arrows point to GFP positive cells (bar: 20um)Back to article page
