Fig. 1: Human α-syn and p-syn expression in mouse brains from 2 to 5 weeks post-injection.

Overexpression of human α-syn and p-syn IHC on coronal brain sections across SN (a). Yellow stars indicate the injection site. b Representative double immunostaining of α-syn and p-syn on mouse brain sections at 4 weeks post-injection. High magnification shows α-syn monomers (bottom middle). Lewy body-like (arrows) and Lewy neurite-like (arrowheads) structures can be found under a confocal microscope (bottom right).
