FIGURE 4.
Immunocytochemical pattern of α-synuclein distribution in OM samples. Alpha-synuclein (4D6, red) shows a diffuse cytosolic distribution as well as a granular labeling around the margin of the plasma membrane of olfactory neurons and non-neuronal-shaped cells. Particularly, olfactory neurons show a thin granular labeling particularly localized at the dendritic knob [outlined square in (A), arrow in detail in (B)]. In the other cells, OMP-positive (green) α-synuclein shows a positivity around the plasmatic membrane. Scale bar (A): 20 μm. Scale bar (B): 10 μm.
