Presence of pS129-positive inclusions in TH-positive neurons and significant reduction of TH-positive neurons in the ipsilateral side of the marmosets (14H and 14I). a, Immunohistochemical staining of substantia nigra with anti-TH antibody and diaminobenzidine staining in 14H. b, Double-labeling of substantia nigra with anti-TH (green) and anti-pS129 (red) antibodies in 14H. c, High magnification of the double-labeling of substantia nigra on the ipsilateral side (indicated by the squares in b). An apparent reduction of TH-positive dopamine neurons was detected in the ipsilateral side of the brain compared to the contralateral side. Areas of pS129-positive inclusions and areas of TH-positive neurons were quantified (d – g). d, e Quantification of pS129-positive inclusions and TH-positive cells in the right and left hemispheres of 14H brain. f, g Quantifications of pS129-positive inclusions and TH-positive cells in the right and left hemispheres of the 14I. To measure positive cells, 7– 9 sections (the numbers are indicated in the columns) were selected. Larger amounts of pS129-positive inclusions were detected and significant reductions of TH-positive neurons were detected in the ipsilateral sides of substantia nigra of the two marmosets. Data were analyzed by Student's t-test. All error bars indicate means ± S.E.M. **p < 0.002, * p < 0.05. Scale bars: 50 μm
