Complement membrane regulatory proteins in human peripheral sural nerve. A–G. Human sural nerve from a healthy control. Cross and longitudinal section immunohistochemical staining for CD55 (DAB, red) (A–C), CD46 (DAB, red) (D–F) and CD35 (G). CD55 staining corresponds to compact myelin (B, green arrow heads) and endothelial blood vessels of the epineurium (A, black arrowhead) and endoneurium (B, black arrowhead), as well as the perineurium (A, blue arrowhead). CD46 was detected in endothelial blood vessels of the epineurium (D, black arrowhead) and endoneurium (E, black arrowhead), as well as the perineurium (D, blue arrowhead). CD35 was not detected anywhere. Scale bars: A, D 100 μm; B, C, E–G 50 μm. Magnifications: A, D ×20; B, C, E–G ×40
