The phenotype is similar to congenital cytomegalovirus brain infection and overlaps with type I interferonopathies, suggesting a role for innate immunity in its pathophysiology. To date, pathophysiological studies have been hindered by the lack of mouse models recapitulating the neuroinflammatory encephalopathy found in patients. In this study, we generated Rnaset2 −/− mice using CRISPR/Cas9-mediated genome editing. Rnaset2 −/− mice demonstrate upregulation of interferon-stimulated genes and concurrent IFNAR1-dependent neuroinflammation, with infiltration of CD8 + effector memory T cells and inflammatory monocytes into the grey and white matter. Single nuclei RNA sequencing reveals homeostatic dysfunctions in glial cells and neurons and provide important insights into the mechanisms of hippocampal-accentuated brain atrophy and cognitive impairment. The Rnaset2 −/− mice may allow the study of CNS damage associated with RNaseT2 deficiency and may be used for the investigation of potential therapies."],["dc.identifier.doi","10.1038/s41467-021-26880-x"],["dc.identifier.pii","26880"],["dc.identifier.pmid","34764281"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/94539"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/361"],["dc.identifier.url","https://rdp.sfb274.de/literature/publications/48"],["dc.identifier.url","https://sfb1286.uni-goettingen.de/literature/publications/141"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-478"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation","TRR 274: Checkpoints of Central Nervous System Recovery"],["dc.relation","SFB 1286: Quantitative Synaptologie"],["dc.relation","SFB 1286 | B06: Die Rolle von RNA in Synapsenphysiologie und Neurodegeneration"],["dc.relation.eissn","2041-1723"],["dc.relation.workinggroup","RG A.

Here, we provide the first evidence that CNS-reactive antibodies (Ab) are similarly capable of initiating an encephalitogenic immune response by targeting endogenous CNS antigen to otherwise inert myeloid APC. In a transgenic mouse model, constitutive production of Ab against myelin oligodendrocyte glycoprotein (MOG) was sufficient to promote spontaneous experimental autoimmune encephalomyelitis (EAE) in the absence of B cells, when mice endogenously contained MOG-recognizing T cells. Adoptive transfer studies corroborated that anti-MOG Ab triggered activation and expansion of peripheral MOG-specific T cells in an Fc-dependent manner, subsequently causing EAE. To evaluate the underlying mechanism, anti-MOG Ab were added to a co-culture of myeloid APC and MOG-specific T cells. At otherwise undetected concentrations, anti-MOG Ab enabled Fc-mediated APC recognition of intact MOG; internalized, processed and presented MOG activated na < ve T cells to differentiate in an encephalitogenic manner. In a series of translational experiments, anti-MOG Ab from two patients with an acute flare of CNS inflammation likewise facilitated detection of human MOG.

Here, we assessed the amount of Wallerian degeneration in brain tissue of multiple sclerosis patients in relation to demyelinating lesion activity and asked whether a transient blockade of Wallerian degeneration decreases axonal loss and clinical disability in a mouse model of inflammatory demyelination. Methods: Wallerian degeneration and acute axonal damage were determined immunohistochemically in the periplaque white matter of multiple sclerosis patients with early actively demyelinating lesions, chronic active lesions, and inactive lesions. Furthermore, we studied the effects of Wallerian degeneration blockage on clinical severity, inflammatory pathology, acute axonal damage, and long-term axonal loss in experimental autoimmune encephalomyelitis using Wallerian degeneration slow (WldS) mutant mice. Results: The highest numbers of axons undergoing Wallerian degeneration were found in the perilesional white matter of multiple sclerosis patients early in the disease course and with actively demyelinating lesions. Furthermore, Wallerian degeneration was more abundant in patients harboring chronic active as compared to chronic inactive lesions. No co-localization of neuropeptide Y-Y1 receptor, a bona fide immunohistochemical marker of Wallerian degeneration, with amyloid precursor protein, frequently used as an indicator of acute axonal transport disturbance, was observed in human and mouse tissue, indicating distinct axon-degenerative processes. Experimentally, a delay of Wallerian degeneration, as observed in WldS mice, did not result in a reduction of clinical disability or acute axonal damage in experimental autoimmune encephalomyelitis, further supporting that acute axonal damage as reflected by axonal transport disturbances does not share common molecular mechanisms with Wallerian degeneration. Furthermore, delaying Wallerian degeneration did not result in a net rescue of axons in late lesion stages of experimental autoimmune encephalomyelitis. Conclusions: Our data indicate that in multiple sclerosis, ongoing demyelination in focal lesions is associated with axonal degeneration in the perilesional white matter, supporting a role for focal pathology in diffuse white matter damage. Also, our results suggest that interfering with Wallerian degeneration in inflammatory demyelination does not suffice to prevent acute axonal damage and finally axonal loss."],["dc.identifier.doi","10.1186/s12974-017-0831-8"],["dc.identifier.isi","000397153100002"],["dc.identifier.pmid","28302146"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14381"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42975"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1742-2094"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Relationship of acute axonal damage, Wallerian degeneration, and clinical disability in multiple sclerosis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

We find that conformation-specific anti-myelin antibodies contribute to cortical demyelination even in the absence of the classical complement pathway. T cells and natural killer cells are relevant for intracortical type 2 but dispensable for subpial type 3 lesions, whereas CCR2(+) monocytes are required for both.

NMO patients harbor autoantibodies against the astrocytic water channel protein, aquaporin-4 (AQP4-IgG), which induce complement-mediated astrocyte lysis and subsequent axon damage. Using spinal in vivo imaging in a mouse model of such astrocytopathic lesions, we explored the mechanism underlying NMO-related axon injury. Many axons showed a swift and morphologically distinct ‘pearls-on-string’ transformation also readily detectable in human NMO lesions, which especially affected small caliber axons independently of myelination. Functional imaging revealed that calcium homeostasis was initially preserved in this ‘acute axonal beading’ state, ruling out disruption of the axonal membrane, which sets this form of axon injury apart from previously described forms of traumatic and inflammatory axon damage. Morphological, pharmacological and genetic analyses showed that AQP4-IgG-induced axon injury involved osmotic stress and ionic overload, but does not appear to use canonical pathways of Wallerian-like degeneration. Subcellular analysis of beaded axons demonstrated remodeling of the axonal cytoskeleton in beaded axons, especially local loss of microtubules. Treatment with the microtubule stabilizer epothilone, a therapy in development for traumatic and degenerative axonopathies, prevented axonal beading, while destabilizing microtubules sensitized axons for beading. Our results reveal a distinct form of immune-mediated axon pathology in NMO that mechanistically differs from known cascades of posttraumatic and inflammatory axon loss, and suggest a new strategy for neuroprotection in NMO and related diseases."],["dc.identifier.doi","10.1093/brain/awac079"],["dc.identifier.pmid","35202467"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/106013"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/454"],["dc.identifier.url","https://rdp.sfb274.de/literature/publications/59"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-530"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation","TRR 274: Checkpoints of Central Nervous System Recovery"],["dc.relation.eissn","1460-2156"],["dc.relation.issn","0006-8950"],["dc.relation.workinggroup","RG Stadelmann-Nessler"],["dc.relation.workinggroup","RG Misgeld"],["dc.relation.workinggroup","RG Schifferer"],["dc.rights","CC BY-NC 4.0"],["dc.title","A new form of axonal pathology in a spinal model of neuromyelitis optica"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
