Abstract
(1) Background: The clinical course of multiple sclerosis (MS) is critically influenced by the expression of different pro-inflammatory and anti-inflammatory cytokines. Interleukin 6 (IL-6) represents a major inflammatory molecule previously associated with exacerbated disease activity in relapsing remitting MS (RR-MS); however, the role of single-nucleotide polymorphisms (SNPs) in the IL-6 gene has not been fully elucidated in MS. (2) Methods: We explored in a cohort of 171 RR-MS patients, at the time of diagnosis, the associations between four IL-6 SNPs (rs1818879, rs1554606, rs1800797, and rs1474347), CSF inflammation, and clinical presentation. (3) Results: Using principal component analysis and logistic regression analysis we identified an association between rs1818879, radiological activity, and a set of cytokines, including the IL-1β, IL-9, IL-10, and IL-13. No significant associations were found between other SNPs and clinical or inflammatory parameters. (4) Conclusions: The association between the rs1818879 polymorphism and subclinical neuroinflammatory activity suggests that interindividual differences in the IL-6 gene might influence the immune activation profile in MS.

Abstract
TNF-α is an important cytokine of the inflammatory response involved in the pathogenesis of relapsing-remitting multiple sclerosis (RRMS). The aim of this study is to explore the association between the promoter polymorphism -308G/A in the TNF-α gene (rs1800629) with genetic susceptibility to RRMS.Methods: A group of 183 RRMS patients and 169 age and gender-matched healthy controls were enrolled in the study. Genotyping of the polymorphism was performed by PCR-restriction fragment length polymorphism and quantification of TNF-α serum levels was conducted by ELISA.Results: The genotype distribution in female patients showed a significantly elevated frequency of heterozygotes (AG) (23.5% vs. 12.8%, OR = 2.072, p = 0.029) in comparison with the healthy women. Substantially higher TNF-α serum levels were observed in females compared to males, in both patients and healthy controls (p < 0.05). According to the genotype, TNF-α levels in the RRMS group were calculated in the following order: for GA/AA genotypes (5.67pg/ml vs. 3.48pg/ml, p = 0.0031) and for GG genotypes (4.58pg/ml vs. 3.52pg/ml, p = 0.00043). Moreover, the carriers of at least one A-allele of -308G/A TNF-α polymorphism (GA+AA) are significantly associated with two fold increased risk for RRMS development (OR = 1.950; p = 0.042) in women in contrast to men as well as associated with early onset of the disease (OR = 2.400; p = 0.021).Conclusion: Our study showed that the level of TNF-α in the serum of patients with RRMS showed a significant association with the -308G/A TNF-α polymorphism and gender dependency.

Abstract
BACKGROUND Optic neuritis (ON) and multiple sclerosis (MS) are complex diseases with multifactorial pathogenesis. The role of genetic factors in the development of these diseases is hypothesized, and specific biochemical components involved in the pathogenesis of ON and MS are yet to be determined. The aim of our study was to determine the associations between IL1RAP rs4624606, IL1RL1 rs1041973, IL-6 rs1800795, and HTRA1 rs11200638 gene polymorphisms and development of ON with or without MS. MATERIALS AND METHODS The study subjects included 80 ON patients and 146 healthy controls (HCs). Genotyping of IL1RAP rs4624606, IL1RL1 rs1041973, IL-6 rs1800795, and HTRA1 rs11200638 was performed using real-time polymerase chain reaction. RESULTS A/C genotype of IL1RL1 rs1041973 was more frequent in ON patients than in HC subjects (p = 0.026). The IL1RL1 rs1041973 A/C genotype was associated with increased odds of ON development under the overdominant (p = 0.041) model. CONCLUSIONS Our study showed that IL1RAP rs4624606, IL-6 rs1800795, and HTRA1 rs11200638 are not associated with an increased risk of developing ON. However, the IL1RL1 rs1041973 A/C genotype might be associated with an increased risk of developing ON.

Abstract
Multiple sclerosis (MS) is one if the common types of autoimmune disorders in developed countries. Various environmental and genetic factors are associated with initiation and progression of MS. It is believed that the life style changes can be one of the main environmental risk factors. The environmental factors are widely studied and reported, whereas minority of reports have considered the role of genetic factors in biology of MS. Although Iran is a low-risk country in the case of MS prevalence, it has been shown that there was a dramatically rising trend of MS prevalence among Iranian population during recent decades. Therefore, it is required to assess the probable MS risk factors in Iran. In the present study, we summarized all of the reported genes until now which have been associated with MS susceptibility among Iranian patients. To clarify the probable molecular biology of MS progression, we categorized these reported genes based on their cellular functions. This review paves the way of introducing a specific population-based diagnostic panel of genetic markers among the Iranian population for the first time in the world.

Abstract
Interleukin-10 (IL-10) is a anti-inflammatory cytokine, which controls inflammation by inhibiting the synthesis of several cytokines produced by Th1 cells and macrophages. The association between Interleukin-10 promoter polymorphisms with the risk of multiple sclerosis (MS) remains inconclusive. In this study, a meta-analysis has been performed to assess the relationship between IL-10 gene polymorphisms rs1800896, rs1800871 and rs1800872 with the risk of MS. Nine case-control studies were selected involving 2755 participants. The association between the polymorphisms and MS was examined by the pooled odds ratios (ORs) with 95% confidence intervals (CIs) in allelic, homozygote, heterozygote, dominant and recessive genetic models. Of analyzed genetic models, the pooled ORs and CIs of each SNPs calculated based on random (I2>50) or fixed effects (I2<50) methods, which showed no significant association (p-value>0.05) of genetic predisposition with MS susceptibility across Asian and Caucasian populations. In addition, assessment based on funnel plot and Egger's linear regression test suggests no publication bias in all analyzed genetic models. Overall, our results demonstrated that rs1800896, rs1800871 and rs1800872 polymorphisms may not be the risk factor for the development of MS in both the populations.

Abstract
Theories for restless legs syndrome (RLS) pathogenesis include iron deficiency, dopamine dysregulation and peripheral neuropathy. Increased prevalence of small intestinal bacterial overgrowth (SIBO) in controlled studies in RLS and case reports of post-infectious RLS suggest potential roles for inflammation and immunological alterations. A literature search for all conditions associated with RLS was performed. These included secondary RLS disorders and factors that may exacerbate RLS. All of these conditions were reviewed with respect to potential pathogenesis including reports of iron deficiency, neuropathy, SIBO, inflammation and immune changes. A condition was defined as highly-associated if there was a prevalence study that utilized an appropriate control group. Small case reports were recorded but not included as definite RLS-associated conditions. Fifty four diseases, syndromes and conditions have been reported to cause and/or exacerbate RLS. Of these, 38 have been reported to have a higher prevalence than age-matched controls, 9 have adequate sized reports and have general acceptance as RLS-associated conditions and 7 have been reported in case report form. Overall, 42 of the 47 RLS-associated conditions (89%) have also been associated with inflammatory and/or immune changes. In addition, 43% have been associated with peripheral iron deficiency, 40% with peripheral neuropathy and 32% with SIBO. Most of the remaining conditions have yet to be studied for these factors. The fact that 95% of the 38 highly-associated RLS conditions are also associated with inflammatory/immune changes suggests the possibility that RLS may be mediated or affected through these mechanisms. Inflammation can be responsible for iron deficiency and hypothetically could cause central nervous system iron deficiency-induced RLS. Alternatively, an immune reaction to gastrointestinal bacteria or other antigens may hypothetically cause RLS by a direct immunological attack on the central or peripheral nervous system.

Abstract
Background: The multifunctional cytokine interleukin-6 (IL-6) is involved in inflammatory processes in the central nervous system. It is well documented that amount of IL-6 is increased in serum, cerebrospinal fluid and central nervous system lesions of patients with multiple sclerosis. A single nucleotide polymorphism at position -174 in the IL-6 gene promotor appears to influence IL-6 expression. Recently, several researchers have focused on HLA-DRB alleles, specifically HLA-DRB1*1501, as a potential risk allele in the pathogenesis of multiple sclerosis. Objective: To investigate the possible influence of IL-6/-174 polymorphisms on susceptibility to multiple sclerosis and its integration with HLA-DRB1*1501. Genomic DNA was extracted from whole blood of 345 patients with multiple sclerosis and 426 control subjects. Method: The SSP-PCR method was used to determine genotypes and Fisher’s exact test was applied to determine differences between groups. HLA-DRB1*1501 was observed more frequently among multiple sclerosis patients compared with healthy subjects (45% and 34%, respectively; OR = 1.6, 95% CI = 1.2—2.2, p = 0.0018). At the IL-6/-174 position, the G allele had higher frequency among multiple sclerosis patients compared with controls (77% and 70%, respectively; OR = 1.4, 95% CI = 1.1—1.8, p = 0.0038). This difference was more significant among HLA-DRB1*1501-positive patients and controls (81% and 67%, respectively; OR = 1.9, 95% CI = 1.5—2.5, p < 0.0001). Results: Our results have shown that the G allele at the IL-6/-174 promoter polymorphism may be associated with development of multiple sclerosis in this population, and may be strengthened by HLA-DRB1*1501. Conclusions: We suggest more studies to confirm these results in other populations.

Abstract
CONTEXT Cytokines are polypeptide regulatory molecules that play a significant role in inflammatory and regulatory responses of the immune system. Several cytokine gene polymorphisms have been studied to date and have been found to be associated with distorted cytokine production or activity by affecting transcriptional regulation and with vulnerability to a variety of infectious and autoimmune diseases as well as to transplant rejection. RESULTS We studied 106 healthy Lebanese individuals using polymerase chain reaction/sequence-specific priming technique to detect 22 single-nucleotide polymorphisms within 13 cytokine genes: IL1alpha 889-T/C, IL1beta 511-T/C, IL1beta +3962-T/C, IL1R pst1 1970-T/C, IL1RA mspa1 11100-T/C, IL4Ralpha 1902-G/A, IL12 1188-C/A, IFNgamma 874-A/T, TGFbeta codon 10-C/T, TGF-beta codon 25-G/C, TNFalpha 308-A/G, TNFalpha 238-A/G, IL2 166-G/T, IL2 330-T/G, IL4 1098-T/G, IL4 590-T/C, IL4 33-T/C, IL6 174-C/G, IL6 nt565-G/A, IL10 1082-G/A, IL10 819-C/T, and IL10 592-A/C. We compared our results to those reported in other populations with similarities observed between the Lebanese and the Italian populations. CONCLUSION The study of different cytokine polymorphisms will aid in understanding the susceptibility of populations to various diseases, and this is the first report from the Lebanese community.

Abstract
Caspase-9 is a primary effector CASP that executes programmed cell death, which plays an important role in the development of multiple sclerosis (MS). Polymorphisms in the CASP-9 gene may influence its activity, thereby modulating the susceptibility to MS. To test this hypothesis, we evaluated a SNP in the CASP-9 gene in a set of Italian patients from Southern Italy and healthy control subjects. Our results suggest that the presence of the G/G genotype represents a higher risk factor in our MS population and a differential production of CASP-9 might be a contributory factor in determining the severity of MS.
