Destabilization of the nodal protein complex leads to sciatic nerve axonal abnormalities. A–J, Transmission electron microscopy (TEM) of cross sections from SNs of NFfx;Ankfx control (A, C) and SLICK-H-CreER;NFfx;Ankfx (B, D–J) mice 60 days after P23/24 injection. Green arrowheads point to normal axons, red arrowheads to abnormal accumulations in the periaxonal space, green arrows to compact myelin, red arrows to abnormal myelin inclusions, and red asterisks to vacuoles. K–N, TEM of longitudinal sections from SNs of NFfx;Ankfx (K, M) and SLICK-H-CreER;NFfx;Ankfx (L–L′, N) mice 60 dpi focusing on the nodal and paranodal areas. Black arrows mark paranodal axo-glial septate-like junctions. Scale bar for A–J = 2 μm, K–L′ = 0.5 μm, M, N = 0.2 μm.
