    In the neurological intensive care unit (neuroICU), patients with severe acute brain injury (SABI) are rendered unable to make their own healthcare decisions. The responsibility of making life-or-death decisions, such as goals of care, is carried by surrogate decision-makers, usually families. In addition to the burden of decision-making, the emotional burden on families is further compounded by prognostication uncertainty, time-pressure for decision-making, and difficulties in understanding and...

    Astrocyte secreted signals substantially affect disease pathology in neurodegenerative diseases. It remains little understood about how proinflammatory cytokines, such as interleukin-1α/tumor necrosis factor-α/C1q (ITC), often elevated in neurodegenerative diseases, alter astrocyte-secreted signals and their effects in disease pathogenesis. By selectively isolating astrocyte exosomes (A-Exo.) and employing cell type-specific exosome reporter mice, our current study showed that ITC cytokines...

  • Quantifying and mitigating motor phenotypes induced by antisense oligonucleotides in the central nervous system

    Saturday, October 26, 2024
    Author(s): Michael P Moazami,Julia M Rembetsy-Brown,Samantha L Sarli,Holly R McEachern,Feng Wang,Masahiro Ohara,Atish Wagh,Karen Kelly,Pranathi Meda Krishnamurthy,Alexandra Weiss,Miklos Marosfoi,Robert M King,Mona Motwani,Heather Gray-Edwards,Katherine A Fitzgerald,Robert H Brown,Jonathan K Watts

    Antisense oligonucleotides (ASOs) are emerging as a promising class of therapeutics for neurological diseases. When injected directly into cerebrospinal fluid, ASOs distribute broadly across brain regions and exert long-lasting therapeutic effects. However, many phosphorothioate (PS)-modified gapmer ASOs show transient motor phenotypes when injected into the cerebrospinal fluid, ranging from reduced motor activity to ataxia or acute seizure-like phenotypes. Using a behavioral scoring assay...

  • Skeletal myotubes expressing ALS mutant SOD1 induce pathogenic changes, impair mitochondrial axonal transport, and trigger motoneuron death

    Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the loss of motoneurons (MNs), and despite progress, there is no effective treatment. A large body of evidence shows that astrocytes expressing ALS-linked mutant proteins cause non-cell autonomous toxicity of MNs. Although MNs innervate muscle fibers and ALS is characterized by the early disruption of the neuromuscular junction (NMJ) and axon degeneration, there are controversies about whether muscle...

    Repeat expansions in the C9orf72 gene are the most common genetic cause of (ALS) and frontotemporal dementia (FTD). Like other genetic forms of neurodegeneration, pinpointing the precise mechanism(s) by which this mutation leads to neuronal death remains elusive, and this lack of knowledge hampers the development of therapy for C9orf72-related disease. We used an agnostic approach based on genomic data (n = 41,273 ALS and healthy samples, and n = 1,516 C9orf72 carriers) to overcome these...

  • Phenotyping in vivo chronic inflammation in multiple sclerosis by combined 11C-PBR28 MR-PET and 7T susceptibility-weighted imaging

    Source: Multiple sclerosis (Houndmills, Basingstoke, England)
    CONCLUSION: ^(11)C-PBR28 imaging reveals more active WM lesions than 7T PRL assessment. Although PRL and PET active lesion counts are related, neurological disability is better explained by PET whole active lesion volume.

  • Development and Validation of a Clinical Score to Predict Epilepsy After Cerebral Venous Thrombosis

    CONCLUSIONS AND RELEVANCE: The DIAS3 score (freely available online) is a simple tool that can help predict the risk of post-CVT epilepsy in individual patients. The model can improve opportunities for personalized medicine and may aid in decision-making regarding antiseizure medication, patient counseling, and facilitation of research on epileptogenesis in CVT.

  • Endovascular therapy versus medical management in isolated posterior cerebral artery acute ischemic stroke: A multinational multicenter propensity score-weighted study

    Source: European stroke journal
    CONCLUSION: EVT for iPCAo is associated with better neurological outcomes and lower mortality compared to MM, without an increased risk of hemorrhagic complications. Nevertheless, these results should be interpreted with caution due to the study's observational design. The findings are hypothesis-generating and highlight the need for future randomized controlled trials to confirm these observations and establish definitive treatment guidelines for this patient population.

    BACKGROUND AND OBJECTIVES: Cerebral venous thrombosis (CVT) is a rare cause of stroke. While the standard treatment is anticoagulation, the type and duration of anticoagulation depends on the underlying etiology. This study aims to identify prevalence, risk factors, and recurrent venous thromboembolism (VTE) rates among patients with idiopathic (cryptogenic) CVT and CVT provoked by transient (peripartum, hormonal treatment, infection, trauma) and persistent (cancer, thrombophilia) factors.

  • Association Between LACE+ Index Risk Category and 90-Day Mortality After Stroke

    Monday, October 14, 2024
    Author(s): Adalia Jun-O'Connell,Brian Silver,Eliza Grigoriciuc,Akanksha Gulati,Kimiyoshi J Kobayashi,Nils Henninger
    Source: Neurology. Clinical practice
    BACKGROUND AND OBJECTIVES: A higher LACE+ index risk category (defined as LACE+ score ≥78) typically calculated before hospital discharge has been associated with increased risk of unplanned 30-day hospital readmissions and early death after hospital discharge. However, its utility to predict poststroke mortality is unknown. Here, we examined whether the LACE+ index risk category assessed at both discharge (dLACE+) and admission (aLACE+) was associated with 90-day mortality after stroke.

  • Emerging roles of antimicrobial peptides in innate immunity, neuronal function, and neurodegeneration

    Thursday, October 10, 2024
    Author(s): Soojin Lee,Neal Silverman,Fen-Biao Gao
    Source: Trends in neurosciences
    Antimicrobial peptides (AMPs), a collection of small proteins with important roles in classical innate immunity, have been extensively studied in multiple organisms, particularly in Drosophila melanogaster. Advances in CRISPR/Cas9 genome editing have allowed individual AMP functions to be dissected, revealing specific and selective roles in host defense. Recent findings have also revealed many unexpected contributions of endogenous AMPs to neuronal functions and neurodegenerative diseases, and...

  • Cytogenetic bands and sharp peaks of Alu underlie large-scale segmental regulation of nuclear genome architecture

    Tuesday, October 08, 2024
    Author(s): Lisa L Hall,Kevin M Creamer,Meg Byron,Jeanne B Lawrence
    Source: Nucleus (Austin, Tex.)
    Cytogenetic bands reflect genomic organization in large blocks of DNA with similar properties. Because banding patterns are invariant, this organization may often be assumed unimportant for genome regulation. Results here challenge that view. Findings here suggest cytogenetic bands reflect a visible framework upon which regulated genome architecture is built. Given Alu and L1 densities differ in cytogenetic bands, we examined their distribution after X-chromosome inactivation or formation of...

  • Paramagnetic Rim Lesions are Highly Specific for Multiple Sclerosis in Real-World Data

    Monday, October 07, 2024
    Author(s): Christopher C Hemond,Sathish K Dundamadappa,Mugdha Deshpande,Jonggyu Baek,Robert H Brown,Carolina Ionete,Daniel S Reich
    Source: medRxiv : the preprint server for health sciences
    CONCLUSIONS: PRL convey high specificity for MS and can aid in the diagnostic evaluation. Modest sensitivity limits their use as single diagnostic indicators. Including lesions with lower confidence ("possible" PRL) rapidly erodes specificity and should be interpreted with caution given the potential harms associated with misdiagnosis.

  • Crucial role of Snf7-3 in synaptic function and cognitive behavior revealed by conventional and conditional knockout mouse models

    Source: Neuroscience
    Snf7-3 is a crucial component of the endosomal sorting complexes required for transport (ESCRT) pathway, playing a vital role in endolysosomal functions. To elucidate the role of Snf7-3 in vivo, we developed conventional-like and conditional Snf7-3 knockout (KO) mouse models using a "Knockout-first" strategy. Conventional-like Snf7-3 KO mice showed significantly reduced Snf7-3 mRNA expression, and older mice (25-40 weeks) exhibited impaired social recognition and increased miniature excitatory...

    Source: Nature biotechnology
    In primary cell types, intracellular deoxynucleotide triphosphate (dNTP) levels are tightly regulated in a cell cycle-dependent manner. We report that prime editing efficiency is increased by mutations that improve the enzymatic properties of Moloney murine leukemia virus reverse transcriptase and treatments that increase intracellular dNTP levels. In combination, these modifications produce substantial increases in precise editing rates.

    Source: Journal of stroke
    CONCLUSION: The results of this study indicate that while MT-IVT and IVT alone show similar functional and mortality outcomes in DMVO patients, MT-IVT presents a higher risk of hemorrhagic complications, thus MT-IVT may not routinely offer additional benefits over IVT alone for all DMVO stroke patients. Further prospective randomized trials are needed to identify patient subgroups most likely to benefit from MT-IVT treatment in DMVO.

    A hexanucleotide (G(4)C(2)) repeat expansion (HRE) within intron one of C9ORF72 is the leading genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). C9ORF72 haploinsufficiency, formation of RNA foci, and production of dipeptide repeat (DPR) proteins have been proposed as mechanisms of disease. Here, we report the first example of disease-modifying siRNAs for C9ORF72 driven ALS/FTD. Using a combination of reporter assay and primary cortical neurons derived from a...

    Small interfering RNAs (siRNAs) represent a novel class of drugs capable of potent and sustained modulation of genes across various tissues. Preclinical development of siRNAs necessitates assessing efficacy and toxicity in animal models. While identifying therapeutic leads with cross-species activity can expedite development, it may compromise efficacy and be infeasible for certain gene targets. Here, we investigate whether deriving species-active siRNAs from potent human-targeting leads-an...

    Hexanucleotide repeat expansion in the C9ORF72 gene is the most frequent inherited cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The expansion results in multiple dipeptide repeat proteins, among which arginine-rich poly-GR proteins are highly toxic to neurons and decrease the rate of protein synthesis. We investigated whether the effect on protein synthesis contributes to neuronal dysfunction and degeneration. We found that the expression of poly-GR proteins...

    SMCHD1 is an epigenetic regulatory protein known to modulate the targeted repression of large chromatin domains. Diminished SMCHD1 function in muscle fibers causes Facioscapulohumeral Muscular Dystrophy (FSHD2) through derepression of the D4Z4 chromatin domain, an event which permits the aberrant expression of the disease-causing gene DUX4. Given that SMCHD1 plays a broader role in establishing the cellular epigenome, we examined whether loss of SMCHD1 function might affect muscle homeostasis...
