Abstract
Neuromyelitis optica spectrum disorder (NMOSD) is a rare relapsing neuroinflammatory autoimmune astrocytopathy, with a predilection for the optic nerves and spinal cord. Most cases are characterised by aquaporin-4-antibody positivity and have a relapsing disease course, which is associated with accrual of disability. Although the prognosis in NMOSD has improved markedly over the past few years owing to advances in diagnosis and therapeutics, it remains a severe disease. In this article, we review the evolution of our understanding of NMOSD, its pathogenesis, clinical features, disease course, treatment options and associated symptoms. We also address the gaps in knowledge and areas for future research focus.

Cell Mol Neurobiol 2023; 43:4071-4101. [PMID: 37955798 DOI: 10.1007/s10571-023-01432-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 10/27/2023] [Indexed: 11/14/2023]
Abstract
MECP2 and its product methyl-CpG binding protein 2 (MeCP2) are associated with multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD), which are inflammatory, autoimmune, and demyelinating disorders of the central nervous system (CNS). However, the mechanisms and pathways regulated by MeCP2 in immune activation in favor of MS and NMOSD are not fully understood. We summarize findings that use the binding properties of MeCP2 to identify its targets, particularly the genes recognized by MeCP2 and associated with several neurological disorders. MeCP2 regulates gene expression in neurons, immune cells and during development by modulating various mechanisms and pathways. Dysregulation of the MeCP2 signaling pathway has been associated with several disorders, including neurological and autoimmune diseases. A thorough understanding of the molecular mechanisms underlying MeCP2 function can provide new therapeutic strategies for these conditions. The nervous system is the primary system affected in MeCP2-associated disorders, and other systems may also contribute to MeCP2 action through its target genes. MeCP2 signaling pathways provide promise as potential therapeutic targets in progressive MS and NMOSD. MeCP2 not only increases susceptibility and induces anti-inflammatory responses in immune sites but also leads to a chronic increase in pro-inflammatory cytokines gene expression (IFN-γ, TNF-α, and IL-1β) and downregulates the genes involved in immune regulation (IL-10, FoxP3, and CX3CR1). MeCP2 may modulate similar mechanisms in different pathologies and suggest that treatments for MS and NMOSD disorders may be effective in treating related disorders. MeCP2 regulates gene expression in MS and NMOSD. However, dysregulation of the MeCP2 signaling pathway is implicated in these disorders. MeCP2 plays a role as a therapeutic target for MS and NMOSD and provides pathways and mechanisms that are modulated by MeCP2 in the regulation of gene expression.

Abstract
Cerebral visual impairments (CVIs) is an umbrella term that categorizes miscellaneous visual defects with parallel genetic brain disorders. While the manifestations of CVIs are diverse and ambiguous, molecular diagnostics stand out as a powerful approach for understanding pathomechanisms in CVIs. Nevertheless, the characterization of CVI disease cohorts has been fragmented and lacks integration. By revisiting the genome-wide and phenome-wide association studies (GWAS and PheWAS), we clustered a handful of renowned CVIs into five ontology groups, namely ciliopathies (Joubert syndrome, Bardet–Biedl syndrome, Alstrom syndrome), demyelination diseases (multiple sclerosis, Alexander disease, Pelizaeus–Merzbacher disease), transcriptional deregulation diseases (Mowat–Wilson disease, Pitt–Hopkins disease, Rett syndrome, Cockayne syndrome, X-linked alpha-thalassaemia mental retardation), compromised peroxisome disorders (Zellweger spectrum disorder, Refsum disease), and channelopathies (neuromyelitis optica spectrum disorder), and reviewed several mutation hotspots currently found to be associated with the CVIs. Moreover, we discussed the common manifestations in the brain and the eye, and collated animal study findings to discuss plausible gene editing strategies for future CVI correction.

Abstract
Neuromyelitis optica spectrum disorders (NMOSD) comprise a variety of disorders being described by optic neuritis and myelitis. This disorder is mostly observed in sporadic form, yet 3% of cases are familial NMO. Different series of familial NMO cases have been reported up to now, with some of them being associated with certain HLA haplotypes. Assessment of HLA allele and haplotypes has also revealed association between some alleles within HLA-DRB1 or other loci and sporadic NMO. More recently, genome-wide SNP arrays have shown some susceptibility loci for NMO. In the current manuscript, we review available information about the role of genetic factors in NMO.

Abstract
Aim This study aimed to determine the correlation between B‐lymphoid tyrosine kinase (BLK) polymorphism, mRNA gene expression of BLK, and NMOSD in a Chinese Han population. Background B‐lymphoid tyrosine kinase gene expressed mainly in B cells plays a key role in various autoimmune disorders. However, no studies have investigated the association of BLK polymorphisms with neuromyelitis optica spectrum disorder (NMOSD). Methods Han Chinese population of 310 subjects were recruited to analyze three single nucleotide polymorphisms (rs13277113, rs4840568, and rs2248932) under allele, genotype, and haplotype frequencies, followed by clinical characteristics stratified analysis. Real‐time PCR was used to analyze mRNA expression levels of BLK in the peripheral blood mononuclear cells of 64 subjects. Results Patients with NMOSD showed lower frequencies of the minor allele G of rs2248932 than healthy controls (odds ratio (OR) =0.57, 95% confidence intervals (CI) 0.39–0.83, p = 0.003). The association between minor allele G of rs2248932 and reduced NMOSD susceptibility was found by applying genetic models of inheritance (codominant, dominant, and recessive) and haplotypes analysis. Subsequently, by stratification analysis for AQP4‐positivity, the minor allele G frequencies of rs2248932 in AQP4‐positive subgroup were significantly lower than in the healthy controls (OR =0.46, 95% CI 0.30–0.72, p = 0.001). Notably, the genotype GG of rs2248932 was more frequent in AQP4‐negative subgroup (n = 14) than in AQP4‐positive subgroup (n = 93) (p = 0.003, OR =0.05, 95% CI =0.01–0.57). BLK mRNA expression levels in the NMOSD patients (n = 36) were lower than in healthy controls (n = 28) (p < 0.05). However, the acute non‐treatment (n = 7), who were untreated patients in the acute phase from the NMOSD group, showed BLK mRNA expression levels 1.8‐fold higher than healthy controls (n = 8) (p < 0.05). Conclusion This study evaluated that the minor allele G of rs2248932 in BLK is associated with reduced susceptibility to NMOSD and protected the risk of AQP4‐positive. BLK mRNA expression in NMOSD was lower as compared to healthy controls while significantly increased in acute‐untreated patients.

Abstract
Background: Single nucleotide polymorphisms (SNPs) that occur within genes encoding inflammatory cytokines can result in quantitative or qualitative changes in their expression or functionality, potentially leading to the development of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. This study sought to evaluate the relationship between SNPs in inflammatory cytokines genes and the incidence of anti-NMDAR encephalitis in the Southern Han Chinese. Methods: In total, we enrolled 107 patients with anti-NMDAR encephalitis as well as 202 inpatient controls who had no first-degree relative with autoimmune diseases. Genotyping determination of all 309 patients was conducted for the IL-1β rs16944, IL-4 rs2243250, IL-4 rs2070874, IL-6 rs1800796, IL-10 rs1800872, and IL-17 rs2275913 gene SNPs. Results: We observed statistically significant differences in the frequencies of G allele in IL-1β rs16944 between anti-NMDAR encephalitis and controls (p = 0.017). Also, IL-1β, IL-4, IL-6, IL-10, and IL-17 SNPs were not associated with the disease (p > 0.05). Conclusions: We found that patients with anti-NMDAR encephalitis exhibit a distinct immunological profile, and we found that the decreased frequency of G allele in IL-1β rs16944 showed a protective role for anti-NMDAR encephalitis in the Southern Han Chinese.

Abstract
Epidemiological studies have suggested differences in the rate of multiple sclerosis (MS) in individuals of European ancestry compared to African ancestry, motivating genetic scans to identify variants that could contribute to such patterns. In a whole-genome scan in 899 African-American cases and 1155 African-American controls, we confirm that African-Americans who inherit segments of the genome of European ancestry at a chromosome 1 locus are at increased risk for MS [logarithm of odds (LOD) = 9.8], although the signal weakens when adding an additional 406 cases, reflecting heterogeneity in the two sets of cases [logarithm of odds (LOD) = 2.7]. The association in the 899 individuals can be fully explained by two variants previously associated with MS in European ancestry individuals. These variants tag a MS susceptibility haplotype associated with decreased CD58 gene expression (odds ratio of 1.37; frequency of 84% in Europeans and 22% in West Africans for the tagging variant) as well as another haplotype near the FCRL3 gene (odds ratio of 1.07; frequency of 49% in Europeans and 8% in West Africans). Controlling for all other genetic and environmental factors, the two variants predict a 1.44-fold higher rate of MS in European-Americans compared to African-Americans.

Mult Scler Relat Disord 2020; 37:101438. [PMID: 32173002 DOI: 10.1016/j.msard.2019.101438] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Revised: 10/03/2019] [Accepted: 10/07/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND X chromosome-linked interleukin-1 receptor-associated kinase (IRAK1) polymorphisms have been demonstrated to be associated with the risks of several autoimmune diseases, such as systemic lupus erythematosus, systemic sclerosis, rheumatoid arthritis, and autoimmune thyroid diseases. However, no studies have investigated the association of IRAK1 polymorphisms with neuromyelitis optica spectrum disorder (NMOSD). This case-control study was performed to determine the correlation between IRAK1 polymorphisms and the risk of NMOSD. METHODS Two single nucleotide polymorphisms (SNPs) rs1059703G>A and rs3027898C>A of IRAK1 were selected and genotyped using SNPscan in a Chinese cohort, including 332 patients with NMOSD and 520 healthy controls. Chi-square tests and logistic regression analyses were used to determine the associations between IRAK1 polymorphisms and the risk of NMOSD. RESULTS Patients with NMOSD showed a lower frequency of the minor allele A of rs1059703 than did controls (Odds ratio [OR] = 0.68; 95% confidence intervals [CI], 0.52-0.88; Pcorr = 0.007). Compared with wild genotype GG of rs1059703, homozygous mutation AA and heterozygous mutation GA were significantly associated with the decreased risk of NMOSD after adjusting for sex and age (adjusted OR = 0.64; 95%CI, 0.49-0.84; Pcorr = 0.002). Similar associations were also observed for IRAK1 rs3027898C>A. Stratification analysis according to sex revealed that the significantly different allele distributions of the two SNPs were mainly found in females. However, IRAK1 polymorphisms were not correlated with aquaporin-4-IgG, onset symptoms, or age at onset. CONCLUSIONS This study is first to demonstrate that X-chromosome-linked IRAK1 polymorphisms are associated with the risk of NMOSD and provide novel insights into the underlying mechanisms of this disease. Further studies are needed to elucidate the function of IRAK1 variants in the pathogenesis of NMOSD and the underlying molecular mechanisms.

Abstract
The prognosis of autoimmune thyroid diseases (AITDs), including Graves' disease (GD) and Hashimoto's disease (HD), varies among patients. The interaction of CD58 and its ligand (CD2) promotes the differentiation of regulatory T cells and suppresses the immune response. To clarify the association of CD58 expression with the pathogenesis and prognosis of AITDs, we genotyped polymorphisms in the CD58 gene including rs12044852A/C (SNP1), rs2300747A/G (SNP2), rs1335532C/T (SNP3), rs1016140G/T (SNP4), rs1414275C/T (SNP5) and rs11588376C/T (SNP6). The CD58 SNPs were genotyped in 177 GD patients, 193 HD patients and 116 healthy volunteers (control subjects). We used the Polymerase chain reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method for the genotyping of SNP1 and SNPs3-6 and the TaqMan® SNP genotyping assay for the genotyping of SNP2. The frequencies of the AA genotype in SNP1 tend to be high in all patients with AITDs than in control subjects, although it was not significant. The GG genotype of SNP2, the CC genotype of SNP3, the TT genotype of SNP4, the CC genotype of SNP5 and the CC genotype of SNP6 were all significantly more frequent in patients with AITDs than in control subjects. The proportion of CD58+ cells in monocytes was significantly lower in healthy individuals with each of these risk genotypes of AITDs and lower in GD and HD patients than that in healthy controls. In conclusion, CD58 SNPs are involved in AITD susceptibility through the reduction in CD58 expression, which probably suppresses regulatory T cells.

Identifying the culprits in neurological autoimmune diseases. J Transl Autoimmun 2019; 2:100015. [PMID: 32743503 PMCID: PMC7388404 DOI: 10.1016/j.jtauto.2019.100015] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 08/27/2019] [Accepted: 09/03/2019] [Indexed: 12/16/2022] Open
Abstract
The target organ of neurological autoimmune diseases (NADs) is the central or peripheral nervous system. Multiple sclerosis (MS) is the most common NAD, whereas Guillain-Barré syndrome (GBS), myasthenia gravis (MG), and neuromyelitis optica (NMO) are less common NADs, but the incidence of these diseases has increased exponentially in the last few years. The identification of a specific culprit in NADs is challenging since a myriad of triggering factors interplay with each other to cause an autoimmune response. Among the factors that have been associated with NADs are genetic susceptibility, epigenetic mechanisms, and environmental factors such as infection, microbiota, vitamins, etc. This review focuses on the most studied culprits as well as the mechanisms used by these to trigger NADs. Neurological autoimmune diseases are caused by a complex interaction between genes, environmental factors, and epigenetic deregulation. Infectious agents can cause an autoimmune reaction to myelin epitopes through molecular mimicry and/or bystander activation. Gut microbiota dysbiosis contributes to neurological autoimmune diseases. Smoking increases the risk of NADs through inflammatory signaling pathways, oxidative stress, and Th17 differentiation. Deficiency in vitamin D favors NAD development through direct damage to the central and peripheral nervous system.

Abstract
Variants at the GTF2I repeat domain containing 1 (GTF2IRD1)–GTF2I locus are associated with primary Sjögren’s syndrome, systemic lupus erythematosus, and rheumatoid arthritis. Numerous studies have indicated that this susceptibility locus is shared by multiple autoimmune diseases. However, until now there were no studies of the correlation between GTF2IRD1–GTF2I polymorphisms and neuromyelitis optica spectrum disorders (NMOSD). This case control study assessed this association by recruiting 305 participants with neuromyelitis optica spectrum disorders and 487 healthy controls at the Department of Neurology, from September 2014 to April 2017. Peripheral blood was collected, DNA extracteds and the genetic association between GTF2IRD1–GTF2I polymorphisms and neuromyelitis optica spectrum disorders in the Chinese Han population was analyzed by genotyping. We found that the T allele of rs117026326 was associated with an increased risk of neuromyelitis optica spectrum disorders (odds ratio (OR) = 1.364, 95% confidence interval (CI) 1.019–1.828; P = 0.037). This association persisted after stratification analysis for aquaporin-4 immunoglobulin G antibodies (AQP4-IgG) positivity (OR = 1.397, 95% CI 1.021–1.912; P = 0.036) and stratification according to coexisting autoimmune diseases (OR = 1.446, 95% CI 1.072–1.952; P = 0.015). Furthermore, the CC genotype of rs73366469 was frequent in AQP4-IgG-seropositive patients (OR = 3.15, 95% CI 1.183–8.393, P = 0.022). In conclusion, the T allele of rs117026326 was associated with susceptibility to neuromyelitis optica spectrum disorders, and the CC genotype of rs73366469 conferred susceptibility to AQP4-IgG-seropositivity in Han Chinese patients. The protocol was approved by the Ethics Committee of West China Hospital of Sichuan University, China (approval number: 2016-31) on March 2, 2016.

Abstract
Neuromyelitis optica (NMO) is an immune-mediated inflammatory disorder of the central nervous system. It is characterized by concurrent inflammation and demyelination of the optic nerve (optic neuritis [ON]) and the spinal cord (myelitis). Multiple studies show variations in prevalence, clinical, and demographic features of NMO among different populations. In addition, ethnicity and race are known as important factors on disease phenotype and clinical outcomes. There are little data on information about NMO patients in underserved groups, including Puerto Rico (PR). In this research, we will provide a comprehensive overview of all aspects of NMO, including epidemiology, environmental risk factors, genetic factors, molecular mechanism, symptoms, comorbidities and clinical differentiation, diagnosis, treatment, its management, and prognosis. We will also evaluate the demographic features and clinical phenotype of NMO patients in PR. This will provide a better understanding of NMO and establish a basis of knowledge that can be used to improve care. Furthermore, this type of population-based study can distinguish the clinical features variation among NMO patients and will provide insight into the potential mechanisms that cause these variations.

Abstract
CD58 is expressed on the surface of antigen-presenting cells, including B-cells, and provides co-stimulation to regulatory T-cells (Treg) through CD2 receptor binding. Tregs appear to be essential suppressors of tissue-specific autoimmune responses. Thereby, CD58 plays protective role in multiple sclerosis (MS) and CD58 was identified among several loci associated with MS susceptibility. Minor (C) variant of the single-nucleotide polymorphism (SNP) rs1335532 is associated with lower MS risk according to genome-wide association studies (GWAS) and its presence correlates with higher CD58 mRNA levels in MS patients. We found that genomic region containing rs1335532 has enhancer properties and can significantly boost the CD58 promoter activity in lymphoblast cells. Using bioinformatics and pull-down assay we found that the protective (C) rs1335532 allele created functional binding site for ASCL2 transcription factor, a target of the Wnt signaling pathway. Both in B-lymphoblastoid cell lines and in primary B-cells, as well as in a monocytic cell line, activation of Wnt signaling resulted in an increased CD58 promoter activity in the presence of the protective but not the risk allele of rs1335532, whereas ASCL2 knockdown abrogated this effect. In summary, our results suggest that ASCL2 mediates the protective function of rs1335532 minor (C) allele in MS.

Abstract
AIMS To investigate the association of the Nectin/Necl family genes with the risk of developing NMOSD. METHODS Whole-exome sequencing was performed on two familial NMOSD cases and two unaffected family members. Additionally, 106 patients with sporadic NMOSD and 212 healthy controls (HCs) underwent screening for mutant Necl2. Finally, the molecular weight and cellular localization of mutant NECL2 was examined in transfected HeLa cells. RESULTS We identified a novel deletion mutation in Necl2 (c.1052_1060delCCACCACCA; p. Thr351_Thr353del), which was associated with disease manifestation in the NMOSD familial cases. The frequency at which the mutation occurred in patients with sporadic NMOSD was significantly higher than for HCs (5.7% and 0, respectively; p<0.01). The mutation was located in the extracellular domain close to the transmembrane region, at a point in the protein sequence characterized by threonine enrichment. The mutant NECL2 had a lower molecular weight and exhibited defective trafficking to the cell surface. CONCLUSIONS Our results suggest that the Necl2 mutation identified herein may be associated with the risk of developing NMOSD. Furthermore, mutated NECL2 may play a role in the pathogenesis of the disease, potentially through its roles in axonal regeneration and/or via neuron-glia interactions that are relevant to myelination.

Association of TNFSF4 Polymorphisms with Neuromyelitis Optica Spectrum Disorders in a Chinese Population. J Mol Neurosci 2017; 63:396-402.

Abstract
The tumor necrosis factor ligand superfamily member 4 (TNFSF4) gene encodes a vital co-stimulatory molecule of the immune system and has been identified as a susceptibility locus for systemic lupus erythematosus, systemic sclerosis, and primary Sjögren's syndrome. However, the association of TNFSF4 polymorphisms with neuromyelitis optica spectrum disorders (NMOSD), an inflammatory, demyelinating autoimmune disease of the central nervous system, has not yet been investigated. To evaluate whether TNFSF4 polymorphisms contribute to risk of NMOSD, four single-nucleotide polymorphisms (SNPs) (rs1234315, rs2205960, rs704840, and rs844648) were selected and genotyped in a cohort of 312 patients with NMOSD and 487 healthy controls. Our study showed that rs844648 was associated with an increased risk of NMOSD, according to the allelic model (OR = 1.30, 95% CI 1.06-1.59, P = 0.011, Pcorr = 0.044). Significant associations of rs844648 (OR = 1.67, 95% CI 1.17-2.38, P = 0.005, Pcorr = 0.02) and rs704840 (OR = 1.75, 95% CI 1.17-2.63, P = 0.007, Pcorr = 0.027) with NMOSD occurrence were also observed under the recessive model. Moreover, linkage disequilibrium analysis revealed two blocks within TNFSF4; in one block, the haplotype Ars844648Grs704840 significantly increased the risk of NMOSD, whereas Grs844648Trs704840 reduced the risk. This study demonstrates an association between TNFSF4 polymorphisms and susceptibility for the development of NMOSD in the Chinese population.
