Al-Naseri MAS, Salman ED, Ad'hiah AH. Relapsing-remitting multiple sclerosis: A profile of interleukine-1 gene cluster polymorphisms in Iraqi patients. J Neuroimmunol 2020; 346:577291. [PMID: 32590124 DOI: 10.1016/j.jneuroim.2020.577291] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Revised: 06/11/2020] [Accepted: 06/12/2020] [Indexed: 12/13/2022]
Abstract
In this case-control study, 68 relapsing-remitting multiple sclerosis (RRMS) patients and 133 control were genotyped for IL1A-889 (rs1800587), IL1B-511 (rs16944), IL1B+3962 (rs1143634), IL1R1pst11970 (rs2234650) and IL1RNmspa1 11,100 (rs315952) variants. Sequence-specific-primer-polymerase-chain-reaction was the genotyping method. Logistic regression analysis demonstrated protective effects of IL1B-511, IL1R1pst11970 and IL1RNmspa1 11,100 against MS incidence, while no association was found with IL1A-889 and IL1B+3962 variants. Allele frequencies showed no significant gender, medication or expanded disability status scale-associated variation. Haplotype analysis suggested 4.31-fold increased odds for MS in subjects with C-T-C-C-T haplotype of the respective loci. In conclusion, IL-1 gene variants influence MS susceptibility in Iraqi population.

Association of Interleukin-1 and Inteleukin-1 Receptor Antagonist Gene Polymorphisms with Multiple Sclerosis in Azeri Population of Iran. Endocr Metab Immune Disord Drug Targets 2020; 20:1110-1116. [PMID: 32148206 DOI: 10.2174/1871530320666200309142541] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 01/14/2020] [Accepted: 01/14/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Cytokines as important mediators have a critical role in appropriate immune responses, the irregular production of which can lead to Multiple Sclerosis (MS). Proinflammatory cytokine interleukin-1 (IL-1) triggers inflammatory responses. Function and production of the cytokine are influenced by IL-1 coding gene polymorphism and those antagonists gene polymorphism. OBJECTIVE The aim of the present study was to evaluate the possible correlation between MS and IL-1 related alleles in Azeri population of Iran. METHODS Variable number tandem repeats (VNTR) genotypes of 150 MS patients and 220 healthy non-relative controls were determined. RESULTS In the healthy controls, genotype TT at IL-1A (-889) location was significantly higher than the MS patients (p=0.0001). However, a significant difference was not found between the two groups in genotypic/allelic frequency at IL- 1B+ 3953 location. Evaluation of the IL-1RA gene revealed that genotype 1/2, and genotype 1/3 were significantly higher in the healthy controls and MS patients, respectively. Our findings indicated that the consumption of fast-food in MS patients was significantly higher than controls (p= <0.05). Also, a considerable number of MS patients had inappropriate dieting behaviors such as not eating breakfast (p= 0.0001), and irregular eating habits (p= 0.0001). CONCLUSION Polymorphisms of the IL-1B genes and common alleles of IL-1RA were not considered as risk factors for MS disease. However, genotype TT at IL-1A (-889) location and the rare allele of IL-1RA3 can be a potential risk factor for the disease. Furthermore, inappropriate dieting behaviors and consumption of fast-food can increase the risk of MS.

Abstract
Objective To examine the effect of variants in genes encoding molecules that are implicated in leukocyte trafficking into the CNS on the development of MS. Methods A total of 389 Greek MS cases and 336 controls were recruited by 3 MS centers in Cyprus and Greece. In total, 147 tagging single nucleotide polymorphisms across 9 genes encoding for P-selectin (SELP), integrins (ITGA4, ITGB1, and ITGB7), adhesion molecules (ICAM1, VCAM1, and MADCAM1), fibronectin 1 (FN1), and osteopontin (SPP1) were genotyped. The clinical end point of the study was diagnosis of MS according to the 2005 revised McDonald criteria. Permutation analysis was used for adjusting for multiple comparisons. Results Overall, 21 variants across SELP, ITGA4, ITGB1, ICAM1, VCAM1, MADCAM1, FN1, and SSP1 genes were each associated with MS (p perm < 0.05). The most significant were rs3917779 and rs2076074 (SELP), rs6721763 (ITGA4), and rs1250258 (FN1), all with a permutation p value of less than 1e-004. Conclusions The current study provides preliminary evidence that variants across genes encoding adhesion molecules, responsible for lymphocyte adhesion and trafficking within the CNS, are implicated in the risk of developing MS.

Abstract
OBJECTIVES To validate in an ethnically homogeneous Greek multiple sclerosis (MS) cohort, genetic risk factors for the disease, identified through a number of previous multi-ethnic genome-wide association studies (GWAS). METHODS A total of 1228 MS cases and 1014 controls were recruited in the study, from 3 MS centers in Greece. We genotyped 35 susceptibility SNPs that emerged from previous GWAS or meta-analyses of GWAS. Allele and genotype single locus regression analysis, adjusted for gender and site, was performed. Permutation testing was applied to all analyses. RESULTS Six polymorphisms reached statistical significance (permutation p value < 0.05). In particular, rs2760524 of LOC105371664, near RGS1 (permutation p value 0.001), rs3129889 of HLA-DRA, near HLA-DRB1 (permutation p value < 1.00e-04), rs1738074 of TAGAP (permutation p value 0.007), rs703842 of METTL1/CYP27B1 (permutation p value 0.008), rs9596270 of DLEU1 (permutation p value < 1.00e-04), and rs17445836 of LincRNA, near IRF8 (permutation p value 0.001) were identified as susceptibility risk factors in our group. CONCLUSION The current study replicated a number of GWAS susceptibility SNPs, which implies that some similarities between the examined Greek population and the MS genetic architecture of the GWAS populations do exist.

Abstract
The aim of the current study was to clarify the role of four common genetic polymorphisms in the interleukin-1β (IL-1B) and interleukin-1α (IL-1A) genes on risk of febrile seizures (FS) by means of meta-analyses. We searched for studies published until February 2018 using ISI Web of Science, Pubmed, Wanfang, and Chinese National Knowledge Infrastructure databases. The pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using MetaAnalyst version Beta 3.13. Seventeen case-control studies were included for meta-analysis. For the IL-1B rs16944 polymorphism, the summary analysis of studies conducted among Caucasian populations showed a significant association in the CT+TT versus CC contrast (OR 1.434, 95% CI 1.153-1.785), while the pooled analysis for Asian populations yielded a significant estimate in the TT versus CC+CT comparison (OR 1.393, 95% CI 1.051-1.846). No association was observed between the IL-1B rs1143627, IL-1B rs1143634, and IL-1A rs1800587 polymorphisms and FS risk. Sensitivity analyses excluding studies showing deviation from Hardy-Weinberg equilibrium did not alter conclusions. The findings of our meta-analysis suggest that the IL-1B rs16944 polymorphism may be an important genetic determinant for FS in Caucasian and Asian populations.

Abstract
DNA methylation may predispose to multiple sclerosis (MS), as aberrant methylation in the promoter regions across the genome seems to underlie several processes of MS. We have currently determined the methylation status of eight genes in relapsing-remitting MS patients. Methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) was used to determine the status of 31 CpG islands, located across eight genes, in 33 healthy individuals and 66 MS patients (33 in relapse and 33 in remission). The methylation levels in the examined sites ranged from 0 to 31%. Methylation positivity for RUNX3 and CDKN2A differed significantly between MS patients and healthy controls. Maximum methylation in RUNX3, CDKN2A, SOCS1, and NEUROG1 genes was significantly different between patients and controls. Roc curves demonstrated that the appropriate cut-offs to distinguish patients from healthy controls were 2% for RUNX3 (OR 3.316, CI 1.207-9.107, p = 0.024) and 3% for CDKN2A (OR 3.077, CI 1.281-7.39, p = 0.018). No difference in methylation was observed between patients in relapse and patients in remission, in any of the genes examined. Methylation patterns of RUNX3 and CDKN2A may be able to distinguish between MS patients and healthy controls, but not between MS patients in relapse and in remission. Graphical Abstract Methylation patterns of RUNX3 and CDKN2A may be able to discriminate healthy individuals from MS patients.

Abstract
Objective: To assess the potential effect of variants in genes encoding molecules that are implicated in leukocyte trafficking into the CNS on the clinical phenotype of multiple sclerosis (MS). Methods: A total of 389 Greek MS cases and 336 controls were recruited in 3 MS centers from Cyprus and Greece. We genotyped 147 tagging single nucleotide polymorphisms (SNPs) in 9 genes encoding for P-selectin (SELP), integrins (ITGA4, ITGB1, and ITGB7), adhesion molecules (ICAM1, VCAM1, and MADCAM1), fibronectin 1 (FN1), and osteopontin (SPP1) involved in lymphocyte adhesion and trafficking into the CNS. Clinical end points of the study were age at MS onset and MS severity as measured by the Multiple Sclerosis Severity Score. Permutation testing was applied to all analyses. Results: SNPs rs6721763 of the ITGA4 and rs6532040 of the SPP1 were found to significantly influence disease severity (permutation p values: 3.00e-06 and 0.009884, respectively). SNP rs1250249 of the FN1 had a dose-dependent effect on age at disease onset (permutation p value: 0.0002). Conclusions: This study provides evidence implicating variants encoding adhesion molecules, responsible for lymphocyte adhesion and trafficking within the CNS, as modifiers of MS disease severity. These genetic biomarkers, which can be available at the time of diagnosis, may be used to assess the biological aggressiveness of the disease and thus guide decisions on treatment.

Abstract
Peripheral circulating cytokines are involved in immune to brain communication and systemic inflammation is considered a risk factor for flaring up the symptoms in most neurodegenerative diseases. We induced both central inflammatory demyelinating lesion, and systemic inflammation with an interleukin-1β expressing adenovector. The peripheral pro-inflammatory stimulus aggravated the ongoing central lesion independently of the blood-brain barrier (BBB) integrity. This model allows studying the role of specific molecules and cells (neutrophils) from the innate immune system, in the relationship between central and peripheral communication, and on relapsing episodes of demyelinating lesions, along with the role of BBB integrity.

Abstract
BACKGROUND Multiple Sclerosis (MS) is a neurodegenerative disease. It involves inflammation and demyelination. Since cytokines play an important role in the development of MS, genes encoding cytokines such as the Interleukin (IL)-1 family are candidate genes for MS susceptibility. OBJECTIVE To determine the relationship between IL-1 gene family and MS in the Turkish population. METHODS A total of 409 MS patients and 256 healthy controls were included in the study. IL-1A -889 (rs1800587), IL-1 RN variable number tandom repeat (VNTR), IL-1B -511 (rs 16944) and IL-1B +3953 (rs 1143634) polymorphisms were investigated from the genomic DNA, obtained via blood samples. RESULTS No association was found between IL-1A and IL-1RN polymorphisms and susceptibility to MS. However, we have found significantly decreased frequency of IL-1B -511 genotype (p = 0.004) in MS patients compared to controls. In addition, there was a significant association between IL-1B -511 (1/2) genotype and early onset MS (EOMS) (p = 0.0001). CONCLUSIONS Individuals with the 2/2 genotype of IL-1B -511 have significantly decreased incidence of MS, suggesting a protective role for this genotype in the Turkish population. Additionally, IL-1B -511 (1/2) genotype was determined as a possible risk factor for EOMS.

Abstract
BACKGROUND Dysregulated levels of interleukin-1 (IL-1) were observed in patients with multiple sclerosis (MS). Previous studies have provided conflicting evidence implicating the IL-1 gene polymorphisms in MS risk. METHODS A meta-analysis of 16 case-control studies involving 3,482 cases and 3,528 controls was conducted to evaluate this association. RESULTS No association was found between the IL-1α -889 (rs1800587), IL-1α +4,845 (rs17561), IL-1β -511 (rs16944), IL-1β +3,953 (rs1143634), IL-1ra variable number tandem repeat (VNTR) polymorphisms and MS risk. However, in subgroup analyses for the IL-1ra VNTR polymorphism, we found that individuals carrying the 2 allele had a 32 % increased risk for bout-onset MS (relapsing remitting and secondary progressive MS) when compared to the LL homozygotes (OR = 1.32, 95 % CI = 1.06-1.66, P (z) = 0.014). CONCLUSION Common variants in the IL-1 region are not associated with MS risk but our data suggest that the IL-1ra VNTR polymorphism might be associated with bout-onset MS subtype.

Abstract
Interleukin-1β (IL-1β) is considered to be one of the most important mediators in the pathogenesis of inflammatory diseases, particularly in neurodegenerative diseases such as multiple sclerosis (MS). MS is a chronic inflammatory disease characterized by demyelination and remyelination events, with unpredictable relapsing and remitting episodes that seldom worsen MS lesions. We proposed to study the effect of a unique component of the inflammatory process, IL-1β, and evaluate its effect in repeated episodes, similar to the relapsing-remitting MS pathology. Using adenoviral vectors, we developed a model of focal demyelination/remyelination triggered by the chronic expression of IL-1β. The long-term expression of IL-1β in the striatum produced blood-brain barrier (BBB) breakdown, demyelination, microglial/macrophage activation, and neutrophil infiltration but no overt neuronal degeneration. This demyelinating process was followed by complete remyelination of the area. This simple model allows us to study demyelination and remyelination independently of the autoimmune and adaptive immune components. Re-exposure to this cytokine when the first inflammatory response was still unresolved generated a lesion with decreased neuroinflammation, demyelination, axonal injury and glial response. However, a second long-term expression of IL-1β when the first lesion was resolved could not be differentiated from the first event. In this study, we demonstrated that the response to a second inflammatory stimulus varies depending on whether the initial lesion is still active or has been resolved. Considering that anti-inflammatory treatments have shown little improvement in MS patients, studies about the behavior of specific components of the inflammatory process should be taken into account to develop new therapeutic tools.
