July 2022 – In contrast to multiple sclerosis, it was not sufficiently investigated whether patients with myelin-oligodendrocyte-glycoprotein-antibody (MOG-IgG)-associated disease (MOGAD) also show a relapse-independent, subclinical retinal neuro-axonal loss. Therefore, initiated by @NeuroVisionLab (Havla Lab), eighty MOGAD patients and 139 healthy controls (HC) were included in a worldwide multicenter study with longitudinal optical coherence tomography (OCT) data. Longitudinally (follow-up up to 3 years), our analysis showed no attack-independent retinal damage in MOGAD. Nevertheless, ongoing neuroaxonal damage or edema resolution appears to occur up to 12 months after optic neuritis (ON), which is longer than has been reported for other forms of ON. These findings suggest that the pathomechanisms underlying optic nerve involvement and the development of OCT retinal changes after ON are different in MOGAD.

May 2022 – The Bareyre lab studied which contralesional circuits adapt following traumatic brain injury (TBI). Laura Empl and Alexandra Chovsepian used in vivo imaging, retrograde labeling, rabies tracing, tissue clearing and functional imaging to demonstrate in Nature Communications that callosal neurons selectively adapt after TBI in mice..

Traumatic brain injury (TBI) results in deficits that are often followed by recovery. The contralesional cortex can contribute to this process but how distinct contralesional neurons and circuits respond to injury remains to be determined. To unravel adaptations in the contralesional cortex, we used chronic in vivo two-photon imaging. We observed a general decrease in spine density with concomitant changes in spine dynamics over time. With retrograde co-labeling techniques, we showed that callosal neurons are uniquely affected by and responsive to TBI. To elucidate circuit connectivity, we used monosynaptic rabies tracing, clearing techniques and histology. We demonstrate that contralesional callosal neurons adapt their input circuitry by strengthening ipsilateral connections from pre-connected areas. Finally, functional in vivo two-photon imaging demonstrates that the restoration of pre-synaptic circuitry parallels the restoration of callosal activity patterns. Taken together our study thus delineates how callosal neurons structurally and functionally adapt following a contralateral murine TBI.

February 2022 – The Beltrán and Gerdes labs studied the immune profiles in the MS TWIN STUDY to differentiate the influence of the environment and genetics in multiple sclerosis. In collaboration with the Becher lab from the University of Zurich they may have discovered precursor cells of the disease-causing T cells.

The impact of genetic risk has been studied for years, however the genetic background is far from deterministic and interaction with environmental factors is needed for MS to evolve. However, which part of the aberrant immune response is guided by either genes or environment is difficult to decipher. With the help of the unique setting of the MS TWIN STUDY we could show that about half of the composition of our immune system is determined by the genetic background. In this project, peripheral blood mononuclear cells of 61 pairs of identical twins with discordance for MS were examined with the use of cutting-edge single-cell technologies and artificial intelligence to describe the immune profiles of the twin pairs in rich detail and with full control of genetic influences. Thereby we could not only identify characteristic proteins in the immune cells of the MS affected twin, but also decode which transcriptional programs are switched on in these cells. Specifically, in the blood of MS twins we detected T cells with characteristics of recently activated cells, which are more likely to migrate into the central nervous system and cause damage there.

November 2021 – Progressive multifocal leukoencephalopathy (PML) is a severe CNS infection that can occur in MS patients treated with Natalizumab. Clinical management of patients with Natalizumab-associated PML is challenging not least to detect, monitor and differentiate PML lesions are limited. Here the Kerschensteiner lab and Kümpfel group teamed up to investigate whether TSPO PET imaging can be applied to monitor the inflammatory activity of PML lesions over time. The results of this monocentre pilot study now indicate that TSPO PET imaging may faciliate longitudinal monitoring of disease activity and help distinguish recurrent multiple sclerosis activity from PML progression.

June 2021 – Nerve cells in the brain possess small protrusions, so called dendritic spines, to communicate with other nerve cells by forming a synapse. These contact sites can be both, short- or long-lived thereby existing for even up to an entire lifetime. Short-lived contact sites reflect an ever- adapting brain, which is necessary to process novel experiences. Long-lived, stable contact sites, on the other hand, form the basis of our memory. But even stable memory content can vary to some extent over time. The basis of this process still remains incompletely understood. The work, published in the journal Science Advances, shows that although a subset of synaptic structures remain present at the same location over a period of at least one month, their subunits underwent a remarkable and unexpected strong change in size and shape. Synaptic structures are thus both stable and dynamic – 'volatile' – at the same time, offering a glimpse into the complexity of synaptic remodelling and computational power mammalian brains are endowed with.

June 2021 – Antibodies (Abs) to myelin oligodendrocyte glycoprotein (MOG) define a distinct disease entity, MOGAD. We report that the intracellular part of MOG, specifically its second hydrophobic domain enhances the recognition of the extracellular part of MOG by autoantibodies from patients. This explains the need for a cell-based assay to identify patients with MOG-Abs. We further found that MOG-Abs from patients require bivalent binding to recognize MOG. Since bivalently bound MOG-Abs poorly bind C1q, this indicates that complement-mediated demyelination is not the major pathomechanism of MOG-Abs.

June 2021 – The Liebscher lab together with the Dupuis group in Strasbourg, France and a highly collaborative international team of several other groups have found the missing pieces between genetic mutations linked to the development of Amyotrophic lateral sclerosis and Frontotemporal Dementia and the consecutive behavioral deficits. Using a wide array of methodological approaches they found that cytoplasmic mislocalization of the protein Fused-in-Sarcoma (FUS) causes its synaptic accumulation and local transcriptional dysregulation, leading to synaptic deficits of primarily inhibitory synapses in frontal cortex, which is causing neuronal hyperexcitability and consequently behavioral alterations. These data thus indicate that cytoplasmic FUS can excert deleterious effects beyond motor neuron degeneration, which are mainly caused by synaptic alterations.

March 2021 – The Dornmair group together with the Meuth/Melzer group from Münster, Germany and several other colleagues investigated antibodies recognizing the neuronal gamma-aminobutyric-acid-A receptor (GABAA-R), which cause severe encephalitis. From the cerebrospinal fluid of a patient with GABAA–R encephalitis, they cloned a highly expressed antibody and showed that it binds the GABAA-R and influences signal transduction in neurons explaining clinical symptoms. They confirmed that the antibody cross-reacts to an onco-protein, which is known to be involved in several malignancies and showed that cross-reactivity to this onco-protein may also be detected in two other GABAA-R patients. This suggests that such cross-reactivity is presumably a key event in the pathogenesis of GABAA-R encephalitis.

January 2021 – Gray matter pathology is a critical contributor to disability in advanced stages of multiple sclerosis. Here the Kerschensteiner lab teamed up with the Misgeld and Merkler lab to investigate how neuronal structure and function is impacted in the neuronal gray matter. In a mouse model they show that gray matter inflammation leads to a synapse loss that is accompagnied by neuronal silencing and can be reversible. Synapse loss is primed by local calcium increases, executed by activated microglial cells and infiltrating monocyte-derived macrophages and can be mitigated by therapeutic strategies that interfer with pathological activation of phagocytes. The authors hope that their work can help the development of therapeutic approaches that curb progression in MS patients.

January 2021 – The Dornmair group together with the Lassmann/Bradl group from the Medical University of Vienna and colleagues of the Meinl and Kawakami groups analyzed a historic case of a patient who died 60 years ago from a disease closely resembling multiple sclerosis, following a misguided immunization with lyophilized calf brain tissue. Transcriptome analyses by mRNAseq and antibody reconstruction by bioinformatics revealed an autoantibody (rAb-hAE) against myelin oligodendrocytes glycoprotein (MOG), similar to the encephalitogenic anti-MOG antibody 8-18C5. Both antibodies induced demyelination after injection into animals, whereas the negative control antibody rMS3-s1 did not. This “archeological neuroimmunology” approach shows that autoimmunization with brain tissue in humans may induce a disease that is similar to multiple sclerosis.

September 2020 – To interrogate the rules that govern myelin replacement in the cortex the Kerschensteiner group together with the Misgeld lab at TUM studied the response to the ablation of single cortical oligodendrocytes. Using timelapse imaging and correlated ultrastructural reconstructions they were able to show that a loss of a single oligodendrocyte is sufficient to cause robust cell and myelin replacement. In this process internodes along partially myelinated axons were typically not reestablished, while myelin sheaths forming continuous patterns showed remarkable homeostatic resiliences and remyelinated with single axon precision. Understanding these principles is particularly important in the context of multiple sclerosis which extensive cortical demyelination is a major pathological feature and target of remyelination therapies.

September 2020 – In this study we used our unique setting of the MS TWIN STUDY to explore the peripheral immune signature in collaboration with the UK Münster. In each twin pair, the immune signatures were remarkably similar, pointing to a strong influence of shared genetic and environmental factors. However, when we focused on a subgroup of seemingly healthy cotwins who showed subtle signs of “subclinical neuro-inflammation,” we identified a distinct signature of memory T cells.

Commentary

November 2019 – Here we report on the principles that drive functional circuit remodeling following spinal cord injury. We demonstrate in this paper that functional circuit remodeling critically depends on the selection of appropriate synaptic connections between cortical projection and spinal relay neurons. In particular, we use in this paper a combination of genetic and chemogenetic tools to modulate NMDA receptor (NMDAR) integrity and function, CREB-mediated transcription, and neuronal firing of relay neurons during injury-induced corticospinal remodeling. We show that NMDAR signaling and CREB-mediated transcription maintain nascent corticospinal tract (CST)–relay neuron contacts. These activity-dependent signals act during a defined period of circuit remodeling and do not affect mature or uninjured circuits. Furthermore, chemogenetic modulation of relay neuron activity reveals that the regrowing CST axons select their postsynaptic partners in a competitive manner and that preventing such activity-dependent shaping of corticospinal circuits limits motor recovery after spinal cord injury.

November 2019 – The early immunological events that drive MS are still enigmatic. To add a piece to the jigsaw we analyzed CSF samples of a unique selection of our MS TWIN STUDY. Using single-cell RNA sequencing we identified clonally expanded CD8+ T cells, plasmablasts, and, to a lesser extent, CD4+ T cells not only from MS co-twins but also from clinical healthy co-twins with signs of subclinical neuroinflammation as detected on MRI and/or CSF. Strikingly, clonally expanded T cells showed characteristics of activated tissue-resident memory T (TRM) cells and were already detectable in prodromal stages but more pronounced in patients with definite MS. Our data provide evidence for very early concomitant activation of 3 components of the adaptive immune system in MS, with a notable contribution of clonally expanded TRM-like CD8+ cells.

Februar 2019 – To reveal the mechanisms that drive inflammatory axon degeneration the Kerschensteiner lab has used in vivo calcium imaging in a multiple sclerosis model. Dynamic tracking of individual axons in the inflamed spinal cord shows that cytoplasmic calcium levels determine the choice between axon loss and survival. Calcium can enter the axon through nanoscale ruptures of the axonal plasma membrane that are induced in inflammatory lesions. These results thus identify a unusual axon injury pathway that can contribute to neurodegeneration in multiple sclerosis and may represent a novel target for protective therapy.

May 2019 – The modest concordance rate for MS in monozygotic twins strongly argues for involvement of epigenetic factors. To check the contribution of epigenetic modifications we looked at the methylomes of 45 pairs from the MS TWIN STUDY together with our collaborators Nicole Souren and Jörn Walter, Saarland Universtiy. We identified seven MS-associated differentially methylated positions (DMPs) of which we validated two, including a region in the TMEM232 promoter and ZBTB16 enhancer. Not expected but not of less relevance we presented epigenetic biomarkers for current interferon-beta treatment, and that the ZBTB16 DMP is a signature for prior glucocorticoid treatment. Taken together, this study represents an important reference for epigenomic MS studies, identifies new candidate epigenetic markers, and highlights treatment effects and genetic background as major confounders.

August 2018 –Autoantibodies against myelin oligodendrocyte glycoprotein (MOG) can be detected in the blood of a proportion of patients with inflammatory demyelinating diseases of the CNS. We affinity-purified MOG-Abs from the blood of two patients. These anti-MOG Abs were pathogenic upon transfer into rats and we could dissect two different mechanisms by which these MOG-Abs enhanced pathology. First, together with cognate MOG-specific T cells, these Abs enhanced T cell infiltration; Second, together with MBP-specific T cells that strongly breach the blood-brain barrier, these MOG-Abs induced demyelination associated with deposition of C9neo, resembling a multiple sclerosis type II pathology. This suggests that MOG-Abs are similarly pathogenic in patients.

Februar 2018 – Mononuclear phagocytes can both promote and inhibit inflammation. Here the Kerschensteiner lab uses an in vivo imaging approach to follow the evolution of phagocyte phenotypes in neuroinflammatory lesions. By tracking phagocytes over time they can show that individual phagocytes switch their phenotype as lesions move from expansion to resolution. This phenotype shift appears to be initiated by signals derived from the nervous system tissue. Understanding the molecular nature of these signals might thus provide the basis for therapeutic manipulation of phagocyte function in the inflamed CNS.

August 2017 – Studies using experimental models have indicated that MS like disease can be triggered in the gut following interactions of brain autoimmune T lymphocytes with local microbiota. In this key paper, we studied the composition of the gut microbiota in our MS TWIN STUDY and in addition transferred human-derived microbiota into transgenic mice expressing a myelin autoantigen-specific T cell receptor. Strikingly, we detected that gut microbiota from MS-affected twins induced CNS-specific autoimmunity at a higher incidence than microbiota from healthy co-twins. Our results offered functional evidence that human microbiome components contribute to CNS-specific autoimmunity and opened up the field for further studies of the gut microbiome in MS.

November 2016 – Damage to oligodendrocytes and their myelin sheaths is a central feature of multiple sclerosis pathology. Here the Kerschensteiner lab investigates how oligodendrocyte damage is initiated in multiple sclerosis (MS) and EAE using in vivo imaging, confocal microscopy as well as electron microscopy. They can show that oligodendrocyte damage spreads centripetally and that the formation of focal myelin outfoldings that they call “myelinosomes” is an early sign of oligodendrocyte damage both in MS and EAE…

January 2016 – How neurodegeneration starts in the brains of progressive multiple sclerosis patients is only incompletely understood. Here the Kerschensteiner lab joined forces with the Merkler lab at the University of Genevan and used confocal microscopy of Golgi-Cox impregnated tissue sections to reconstruct single cortical projection neurons in brain sections from multiple sclerosis and control patients. Their study reveals a widespread and pronounced loss of dendritic spines that occurs independently of cortical demyelination and axon loss and indicates the presence of a primary synaptic pathology in multiple sclerosis…

May 2015 – Following spinal cord injury, transected projections form detour circuits that circumvent the lesion and contribute to functional recovery. The formation of new synaptic contacts is a crucial step of the process, but its molecular regulation is currently not understood. Members of the FGF family can promote synapse formation during nervous system development, suggesting that they might have a similar function in the injured adult CNS. Here, we show that: (i) FGF22 and FGF22 receptors are expressed in the adult nervous system. (ii) FGF22 deficiency or deletion of FGF22 receptors restricts the formation and maturation of new synapses in the injured spinal cord. (iii) Genetic disruption of FGF22 signaling impedes spontaneous functional recovery following spinal cord injury
