Published customer image:NLs on MRI and tissue sections stained for PLP and iron. Examples Examples of NLs from tissue MS1 (A, B and C) identified on MRI magnitude (TE = 25.2 ms) and R2* images as well as color-coded PLP-staining and iron staining. Red arrows point towards NLs identified by MRI and confirmed to correspond to area of demyelination by the color-coded PLP staining. Blue arrows point towards NLs identified by the color-coded PLP staining and only retrospectively identified by MRI. Black arrows and black box point towards NLs identified by the color-coded PLP staining and not by MRI even upon a second retrospective image inspection. In the black box we include a large area of demyelination which goes entirely undetected by MRI. In the color-coded PLP staining of figure: green = complete WM demyelination, red = complete GM demyelination, yellow = areas of variably reduced myelin density.From:Yao B, Hametner S, van Gelderen P, Merkle H, Chen C, et al.

Published customer image: Iron loss in NLs. PLP myelin staining (B) and iron staining (C) on two consecutive slides of tissue MS2 disclose iron loss together with myelin loss in a NL (red arrows). Higher magnification (D, E, F, G) of PLP (D, F) and iron stainings (E, G). In NAGM (D, E), iron is present in oligodendrocytes (black arrow and inset in E) and myelin sheaths. In a NL (F, G), iron is removed from the demyelinated cortical parenchyma and present in perivascular macrophages and microglia (black arrow and inset in G).From:Yao B, Hametner S, van Gelderen P, Merkle H, Chen C, et al.

Published customer image: NL scheme and PLP staining. (A) Type-I NL with demyelination of the whole width of the cortex (#) and adjacent WM (*). (B) Type-II intracortical lesion evolving around a vessel. (C) Type-III subpial NL. Demyelination spreads from the pial surface until cortical layer 3. Scale bars represent 500 um.From:Yao B, Hametner S, van Gelderen P, Merkle H, Chen C, et al. (2014) 7 Tesla Magnetic Resonance Imaging to Detect Cortical Pathology in Multiple Sclerosis.
