Transcription Factor Runx3 Mediates Plasticity Of Thgm Cells Toward Th1 Phenotype, Javad Rasouli, Giacomo Casella, Weifeng Zhang, Dan Xiao, Gaurav Kumar, Paolo Fortina, Guang-Xian Zhang, Bogoljub Ciric, Abdolmohamad Rostami

Department of Neurology Faculty Papers

GM-CSF-producing T helper (Th) cells play a crucial role in the pathogenesis of autoimmune diseases such as multiple sclerosis (MS). Recent studies have identified a distinct population of GM-CSF-producing Th cells, named ThGM cells, that also express cytokines TNF, IL-2, and IL-3, but lack expression of master transcription factors (TF) and signature cytokines of commonly recognized Th cell lineages. ThGM cells are highly encephalitogenic in a mouse model of MS, experimental autoimmune encephalomyelitis (EAE). Similar to Th17 cells, in response to IL-12, ThGM cells upregulate expression of T-bet and IFN-γ and switch their phenotype to Th1. Here we show that …

B- And T-Cell Subset Abnormalities In Monogenic Common Variable Immunodeficiency, Saba Fekrvand, Shaghayegh Khanmohammadi, Hassan Abolhassani, Reza Yazdani

Department of Neurology Faculty Papers

Common variable immunodeficiency (CVID) is a heterogeneous group of inborn errors of immunity characterized by reduced serum concentrations of different immunoglobulin isotypes. CVID is the most prevalent symptomatic antibody deficiency with a broad range of infectious and non-infectious clinical manifestations. Various genetic and immunological defects are known to be involved in the pathogenesis of CVID. Monogenic defects account for the pathogenesis of about 20-50% of CVID patients, while a variety of cases do not have a defined genetic background. Deficiencies in molecules of B cell receptor signaling or other pathways involving B-cell development, activation, and proliferation could be associated with …

Department of Neurosurgery Faculty Papers

Introduction: Progress in degenerative cervical myelopathy (DCM) is hindered by inconsistent measurement and reporting. This impedes data aggregation and outcome comparison across studies. This limitation can be reversed by developing a core measurement set (CMS) for DCM research. Previously, the AO Spine Research Objectives and Common Data Elements for DCM (AO Spine RECODE-DCM) defined 'what' should be measured in DCM: the next step of this initiative is to determine 'how' to measure these features. This protocol outlines the steps necessary for the development of a CMS for DCM research and audit.

Methods and analysis: The CMS will be developed in …

Role Of Atogepant In The Treatment Of Episodic Migraines: Clinical Perspectives And Considerations, Fred Cohen, Hsiangkuo Yuan

Department of Neurology Faculty Papers

Advances in molecular biology and neuroscience have led to the discovery of calcitonin gene-related peptide (CGRP), a 37 amino-acid neuropeptide that plays a critical role in the pathogenesis of migraine. CGRP receptor antagonist, also known as gepant, is an oral medication that inhibits the CGRP-related nociceptive signaling pathway. To date, three gepants are approved by the FDA for migraine treatment. Atogepant is a 2nd-generation gepant that non-competitively antagonizes CGRP receptors inhibiting neurogenic inflammation and pain sensitization. With its long half-life and minimal cardiovascular or liver toxicity, it is the first in its class approved primarily for migraine prevention. This article …

Department of Neurology Faculty Papers

SignificanceMultiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), are autoimmune diseases characterized by accumulation of myeloid cells in the central nervous system (CNS). Both harmful and beneficial myeloid cells are present in EAE/MS, and a goal of MS therapy is to preferentially remove harmful myeloid cells. The receptor for CSF-1 (CSF-1R) is found on myeloid cells and is important for their survival. CSF-1R can bind two ligands, CSF-1 and IL-34, but it is not known whether their functions in EAE/MS differ. We found that blocking CSF-1 depleted only harmful myeloid cells in the CNS and suppressed EAE, …

Immunomodulatory Effects And Clinical Benefits Of Intravenous Immunoglobulin In Myasthenia Gravis., Marinos C Dalakas, Andreas Meisel

Department of Neurology Faculty Papers

Introduction Myasthenia gravis (MG) is an antibody-mediated disease that develops in the majority of patients mainly as a result of acetylcholine receptor (AChR) autoantibodies. This process is mediated by a series of immunoregulatory events. Therapeutic targets for MG include suppression of circulating antibodies or antibody production, suppression of complement activation, and immunomodulation of cytokines or T cells. Intravenous immunoglobulin (IVIg) has an effect on all of these mechanisms. Areas covered This narrative review explores the broad immunomodulatory effects of IVIg in MG and provides an update on IVIg treatment for MG. Expert opinion IVIg has a range of immunomodulatory effects …

The Role Of The Complement System In Chronic Inflammatory Demyelinating Polyneuropathy: Implications For Complement-Targeted Therapies., Luis A Querol, Hans-Peter Hartung, Richard A Lewis, Pieter A Van Doorn, Timothy R Hammond, Nazem Atassi, Miguel Alonso-Alonso, Marinos Dalakas

Department of Neurology Faculty Papers

Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common, heterogeneous, immune-mediated neuropathy, characterized by predominant demyelination of motor and sensory nerves. CIDP follows a relapsing-remitting or a progressive course and causes substantial disability. The pathogenesis of CIDP involves a complex interplay of multiple aberrant immune responses, creating a pro-inflammatory environment, subsequently inflicting damage on the myelin sheath. Though the exact triggers are unclear, diverse immune mechanisms encompassing cellular and humoral pathways are implicated. The complement system appears to play a role in promoting macrophage-mediated demyelination. Complement deposition in sural nerve biopsies, as well as signs of increased complement activation in …

Ocular light exposure has important influences on human health and well-being through modulation of circadian rhythms and sleep, as well as neuroendocrine and cognitive functions. Prevailing patterns of light exposure do not optimally engage these actions for many individuals, but advances in our understanding of the underpinning mechanisms and emerging lighting technologies now present opportunities to adjust lighting to promote optimal physical and mental health and performance. A newly developed, international standard provides a SI-compliant way of quantifying the influence of light on the intrinsically photosensitive, melanopsin-expressing, retinal neurons that mediate these effects. The present report provides recommendations for lighting, …

Multiple Sclerosis: Relationship Between Locus Of Control And Quality Of Life In Persons With Low Versus High Disability, Judith Bijoux Leist, Thomas P. Leist

Department of Neurology Faculty Papers

Background: Health Locus of Control (HLOC) is the degree to which individuals believe that their health outcomes are controlled by 'external' factors - environmental forces, chance, fate, other people, or some higher power - or by 'internal' factors - their own behavior or action. Most of the literature on HLOC associates an Internal Health Locus of Control (IHLOC) to pro-health behaviors and better health outcomes. However, a few studies also suggest that in chronic illnesses, an External Health Locus of Control (EHLOC) could be beneficial with respect to pro-health behaviors and perceptions of Quality of Life (QoL), challenging assumptions about …

Characterization Of Basal Ganglia Volume Changes In The Context Of Hiv And Polysubstance Use, Andrew J Monick, Michelle R Joyce, Natasha Chugh, Jason A Creighton, Owen P Morgan, Eric C Strain, Cherie L Marvel

Department of Medicine Faculty Papers

HIV and psychoactive substances can impact the integrity of the basal ganglia (BG), a neural substrate of cognition, motor control, and reward-seeking behaviors. This study assessed BG gray matter (GM) volume as a function of polysubstance (stimulant and opioid) use and HIV status. We hypothesized that comorbid polysubstance use and HIV seropositivity would alter BG GM volume differently than would polysubstance use or HIV status alone. We collected structural MRI scans, substance use history, and HIV diagnoses. Participants who had HIV (HIV +), a history of polysubstance dependence (POLY +), both, or neither completed assessments for cognition, motor function, and …

Gender Parity In Authorship Of Published Randomized Clinical Trials In Stroke Neurology From 2000 To 2021., Noor F Shaik, Ali A Saherwala, Diana L Tzeng

Department of Neurology Faculty Papers

Gender parity is a crucial goal in clinical medicine so that women have equal access and representation. Although approximately half (46%) of US neurology residents and fellows are female, proportions of female assistant, associate, and full professors are 49%, 41%, and 23%, respectively. This has far-reaching effects, from clinical publications to invited speakerships.Although a study noted increasing trends in female authorship in high-impact neurology journals the current literature lacks evidence on a more informative benchmark—first and last authorship in randomized clinical trials (RCTs), which is typically considered for career advancement. This study assessed annual proportions and trends of female first …

Degenerative Cervical Myelopathy, Ratko Yurac, José Manuel Matamala, Juan José Zamorano, James S Harrop, Benjamin M Davies, Aria Nouri, Michael G Fehlings

Department of Neurology Faculty Papers

Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Its prevalence is increasing as a result of population aging. The diagnosis of DCM is often delayed or overlooked, resulting in secondary neurologic morbidity. The natural course of DCM typically presents as a gradual neurological deterioration, with symptoms ranging from muscle weakness to complete paralysis, with variable degrees of sensory deficits and sphincter dysfunction. Magnetic resonance imaging (MRI) and electrophysiological studies allow the assessment of spinal cord function and its structural damage to determine treatment and clinical outcomes. All patients with signs and symptoms consistent …
