Immunohistochemical staining of PRXs in EAE spinal cords
HE staining revealed cellular infiltration in the meninges and parenchyma of EAE spinal cords (Fig. 2). Among the PRXs families (PRX 1-6), only PRX5 staining was confirmed in EAE spinal cords (Fig. 2). PRX5 staining was observed in CD45+ infiltrating cells in the inflammatory lesions (Fig. 3).
