zing activity, whereas pSIgA, but not IgG, significantly inhibited the production of progeny virus particles from infected cells. Plaque formation was also significantly reduced by pSIgA, but not IgG. These effects were seen in infection with IAVs of several different HA subtypes. Based on our findings, we propose an antibody-mediated host defense mechanism by which mucosal immunity may contribute to broad cross-protection from IAVs of multiple HA subtypes, including viruses with pandemic potential.

The majority of HAdV infections are self-limited, but recurring infection is frequently encountered in young children that may require hospitalization. In this study, we surveyed the presence of HAdV in tonsillectomy samples and investigated epigenetic conditions that contributed to HAdV reactivation. HAdV DNA was detected from 86.7% donors. The lymphocytes isolated from the samples failed to produce infectious HAdV after incubation, suggesting the viruses remained latent status. To determine whether epigenetic factors played a role in HAdV reactivation, isolated lymphocytes were treated with a small compound library. Viral DNA replication and infectious HAdV production was assayed by PCR and by a secondary infection assay. We identified several compounds, mainly pan- and selective- HDAC inhibitors, that showed activity to reactivate HAdV from latency. The viruses were isolatedetylase inhibitors that promoted adenovirus reactivation evidenced by increased viral DNA replication and production of infectious viruses. The human tonsils are covered with bacterial pathogens that may utilize pathogen-associated pattern molecules or metabolites to cause epigenetic activation and proinflammatory gene transcription, which may lead to viral reactivation from latency. The study shows that recurrent adenovirus infection could arise from reactivation of residing virus from previous infections. selleck inhibitor Copyright © 2020 American Society for Microbiology.West Nile virus (WNV), a member of the Flavivirus genus and currently one of the most common arboviruses worldwide, is associated with severe neurological disease in humans. link2 Its high potential to re-emerge and rapidly disseminate makes it a bona fide global public health problem. The surface membrane glycoprotein (M) has been associated with Flavivirus-induced pathogenesis. Here we identify a key amino acid residue at position 36 of the M protein whose mutation impacts WNV secretion and promotes viral attenuation. link3 We also identified a compensatory site at position M-43 whose mutation stabilizes M-36 substitution both in vitro and in vivo Moreover, we find that introduction of the two mutations together confers a full attenuation phenotype and protection against wild-type WNV lethal challenge, eliciting potent neutralizing antibody production in mice. Our study thus establishes the M protein as a new viral target for rational design of attenuated WNV strains.IMPORTANCE West Nile virus (WNV) is a worldwide (re)al.OBJECTIVE To validate quantitative diffusion-weighted imaging (DWI) MRI thresholds that correlate with poor outcome in comatose cardiac arrest survivors, we conducted a clinician-blinded study and prospectively obtained MRIs from comatose patients after cardiac arrest. METHODS Consecutive comatose post-cardiac arrest adult patients were prospectively enrolled. MRIs obtained within 7 days after arrest were evaluated. The clinical team was blinded to the DWI MRI results and followed a prescribed prognostication algorithm. Apparent diffusion coefficient (ADC) values and thresholds differentiating good and poor outcome were analyzed. Poor outcome was defined as a Glasgow Outcome Scale score of ≤2 at 6 months after arrest. RESULTS Ninety-seven patients were included, and 75 patients (77%) had MRIs. In 51 patients with MRI completed by postarrest day 7, the prespecified threshold of >10% of brain tissue with an ADC 10% of brain tissue in an MRI obtained by postarrest day 7 is highly specific for poor outcome in comatose patients after cardiac arrest. © 2020 American Academy of Neurology.OBJECTIVE To evaluate the association between long-term exposure to ambient air pollution and cognitive decline in older adults residing in an urban area. METHODS Data for this study were obtained from 2 prospective cohorts of residents in the northern Manhattan area of New York City the Washington Heights-Inwood Community Aging Project (WHICAP) and the Northern Manhattan Study (NOMAS). Participants of both cohorts received in-depth neuropsychological testing at enrollment and during follow-up. In each cohort, we used inverse probability weighted linear mixed models to evaluate the cross-sectional and longitudinal associations between markers of average residential ambient air pollution (nitrogen dioxide [NO2], fine particulate matter [PM2.5], and respirable particulate matter [PM10]) levels in the year prior to enrollment and measures of global and domain-specific cognition, adjusting for sociodemographic factors, temporal trends, and censoring. RESULTS Among 5,330 participants in WHICAP, an increase in NO2 was associated with a 0.22 SD lower global cognitive score at enrollment (95% confidence interval [CI], -0.30, -0.14) and 0.06 SD (95% CI, -0.08, -0.04) more rapid decline in cognitive scores between visits. Results were similar for PM2.5 and PM10 and across functional cognitive domains. We found no evidence of an association between pollution and cognitive function in NOMAS. CONCLUSION WHICAP participants living in areas with higher levels of ambient air pollutants have lower cognitive scores at enrollment and more rapid rates of cognitive decline over time. In NOMAS, a smaller cohort with fewer repeat measurements, we found no statistically significant associations. These results add to the evidence regarding the adverse effect of air pollution on cognitive aging and brain health. © 2020 American Academy of Neurology.Funds flow arrangements define the financial relationships between departments, medical centers, and university entities within a coordinated academic health system. Although these funds flow frameworks differ, common themes emerge including those that are unique in their influence on academic departments of neurology. Here, we review various funds flow models and their application. Four typical models are described, highlighting the advantages and disadvantages of each for neurology, keeping in mind that most academic health systems use a hybrid model. Several considerations are important when neurology departmental leadership participates in crafting or revising of these funds flow agreements, including choice of benchmarking targets, planning and funding for future growth, demonstrating value, and supporting nonclinical missions including education and research. The American Academy of Neurology Academic Initiative aims to continue to help academic departments nationally understand these issues and define funds flow arrangements that incorporate the unique characteristics of our specialty and allow us to provide outstanding care for patients while supporting the broad missions of neurology departments. © 2020 American Academy of Neurology.OBJECTIVE To determine whether Scrambler therapy is an effective, acceptable, and feasible treatment of persistent central neuropathic pain in patients with neuromyelitis optica spectrum disorder (NMOSD) and to explore the effect of Scrambler therapy on co-occurring symptoms. METHODS We conducted a randomized single-blind, sham-controlled trial in patients with NMOSD who have central neuropathic pain using Scrambler therapy for 10 consecutive weekdays. Pain severity, pain interference, anxiety, depression, and sleep disturbance were assessed at baseline, at the end of treatment, and at the 30- and 60-day follow-up. RESULTS Twenty-two patients (11 per arm) were enrolled in and completed this trial. The median baseline numeric rating scale (NRS) pain score decreased from 5.0 to 1.5 after 10 days of treatment with Scrambler therapy, whereas the median NRS score did not significantly decrease in the sham arm. Depression was also reduced in the treatment arm, and anxiety was decreased in a subset of patients who responded to treatment. These symptoms were not affected in the sham arm. The safety profiles were similar between groups. CONCLUSIONS Scrambler therapy is an effective, feasible, and safe intervention for central neuropathic pain in patients with NMOSD. Decreasing pain with Scrambler therapy may additionally improve depression and anxiety. CLINICALTRIALSGOV IDENTIFIER NCT03452176. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that Scrambler therapy significantly reduces pain in patients with NMOSD and persistent central neuropathic pain. © 2020 American Academy of Neurology.Calcineurin inhibitors, such as tacrolimus (FK506) and cyclosporine, are widely used as standard immunosuppressants in organ transplantation recipients. However, these drugs can cause severe pain in patients, commonly referred to as calcineurin inhibitor-induced pain syndrome (CIPS). Although calcineurin inhibition increases N-methyl-D-aspartate receptor (NMDAR) activity in the spinal cord, the underlying mechanism remains enigmatic. Using an animal model of CIPS, we found that systemic administration of FK506 in male and female mice significantly increased the amount of α2δ-1-GluN1 complexes in the spinal cord and the level of α2δ-1-bound GluN1 proteins in spinal synaptosomes. Treatment with FK506 significantly increased the frequency of miniature excitatory postsynaptic currents (EPSCs) and the amplitudes of monosynaptic EPSCs evoked from the dorsal root and puff NMDAR currents in spinal dorsal horn neurons. Inhibiting α2δ-1 with gabapentin or disrupting the α2δ-1-NMDAR interaction with α2δ-1Tat peptide comin inhibition enhances physical interaction between α2δ-1 and NMDA receptors and their synaptic trafficking in the spinal cord. α2δ-1 is essential for calcineurin inhibitor-induced aberrant activation of presynaptic and postsynaptic NMDA receptors in the spinal cord. Furthermore, inhibiting α2δ-1 or disrupting α2δ-1-NMDA receptor interaction reduces calcineurin inhibitor-induced pain hypersensitivity. Eliminating NMDA receptors in primary sensory neurons or α2δ-1 knockout also attenuates calcineurin inhibitor-induced pain hypersensitivity. This new information extends our mechanistic understanding of the role of endogenous calcineurin in regulating synaptic plasticity and nociceptive transmission and suggests new strategies for treating this painful condition.

Here we report a combination of gene-circuit-behavior analyses including MECP2 co-expression network, locomotive and cognitive behaviors, EEG and fMRI in five MECP2 overexpressed (Macaca fascicularis; 3 female) and twenty wild-type (Macaca fascicularis; 11 female) monkeys. Whole-genome expression analysis revealed MECP2 co-expressed genes significantly enriched in GABA-related signaling pathways, whereby reduced beta synchronization within fronto-parieto-occipital networks was associated with abnormal locomotive behaviors. Meanwhile, MECP2-induced hyper-connectivity in prefrontal and cingulate networks accounted for regressive deficits in reversal learning tasks. Furthermore, we stratified a cohort of 49 autisms and 72 controls out of 1112 subjects using functional connectivity patterns, and identified similar dysconnectivity profiles as in monkeys.
