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.

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).

Validation of monomer and oligomer preference of αSN interacting proteins. Proteins pulled down by monomer αSN (M), oligomer αSN (O), and buffer control (B) from porcine (A-F) and human (G-I) brain extracts were analyzed by immunoblotting using antibodies against antigens selected among the monomer and oligomer binding proteins. Monomer binding antigens were myelin proteolipid protein (mPLP) and Abl interactor 1 (Abl1) and oligomer binding proteins were glial fibrillary acidic protein (GFAP), glutamate decarboxylase 2 (GAD2), and synapsin 1 (Syn1). VAMP-2 was tested because it has been reported to bind &apha;SN, although it was not detected in our proteomic analysis. One representative of three experiments is presented for porcine αSN binding proteins (A, C, E), and the quantification of the three experiments is presented in panels B, D, F. The quantification of bands was performed after subtracting the non-specific signal in the buffer control from the specific bands in monomer and oligomer samples. Bars represent mean ratio between monomer and oligomer ± S.D. of the three replicates. The values for binding to monomer and oligomer were compared by Student's t-test and the resulting p-values are listed above the bars. * Indicates that the band intensity from oligomer did not differ significantly from background making quantifications impracticable. In order to ensure that the interaction were not due to species differences between human and porcine proteins we conducted validations in human brain extracts. One representative of two experiments is presented for each validated protein. The validation for both porcine and human of mPLP, Abl1, Syn1 and VAMP-2 was conducted in the LP2 fraction enriched in synaptic vesicle and the validation to GFAP and GAD2 in the LS1 fraction of synaptosomal lysate.

Image caption:
Preactive lesions are composed of clusters of HLA-DR-positive microglia. In NAWM, i.e., in the absence of apparent myelin loss (A, E: proteolipid protein) preactive lesions are defined as circumscribed nodules of activated microglia expressing HLA-DR (B, C) and CD68 (D). Preactive lesions are predominantly observed in blocks containing active lesions (E: proteolipid protein; F, G: HLA-DR). Figure1G represents a magnification of the outlined square in (F). In some cases microglial nodules are surrounded by a halo devoid of microglia (H: HLA-DR). Original magnifications: A, B: 20×; C, D: 40×; E, F: 4×; G, H: 40×.

Image caption:
LRP1 expression is increased in MS lesions. a Immunohistochemistry on consecutive sections from an early active (EA) MS lesion (upper row) shows: (1) myelin (PLP) laden macrophages consistent with ongoing demyelinating activity, (2) abundant macrophage infiltration (CD68), (3) hypertrophic reactive astrocytes indicating gliosis (GFAP), and (4) LRP1 immunoreactivity present on both astrocytes (arrowhead) and macrophages (arrow and inset). In contrast, the periplaque gray matter (PPGM, lower row) shows: (1) normal appearing myelin (PLP), (2) limited microglial reactivity (CD68), (3) astrocytes with regular size and morphology (GFAP), and (4) limited LRP1 immunoreactivity. (Scale bars?=?20 μm). b Luxol Fast Blue histology (LFB) and immunofluorescence for CD68 and LRP1 shows that myeloid cells express LRP1 within the lesion (Scale bar?=?100 μm)
