This paper has aimed to review the available evidence on the association between Interleukin (IL) -10 -1082G/A, -592C/A gene polymorphisms and the risk of human immunodeficiency virus-1(HIV-1) infection. The data of PubMed updated in May 2021 were retrieved. The HIV infection risks were estimated in allelic, recessive, dominant, homozygous, heterozygous, over-dominant models of IL-10-1082G/A and-592C/A gene locus as odds ratio (OR) with the corresponding 95% confidence interval (95% CI). The correlation was not significant between -1082G/A polymorphism and HIV-1 susceptibility (allelic model (G vs. A: OR (95% CI)=0.968 (0.878-1.067)); recessive model (GG vs. AA+AG: OR (95% CI)=0.940, (0.771-1.146)); dominant model (GG+AG vs. AA: OR (95% CI)=0.967(0.846-1.106)); homozygous model (GG vs. AA: OR (95% CI)=0.971(0.780-1.209)); heterozygous model (AG vs. AA: OR (95% CI)=0.988(0.797-1.224)) and over-dominant model (GG+AA vs. AG: OR (95% CI)=0.969(0.781-1.201)). IL-10-592C/A polymorphism might be related to HIV-1 in allelic model, dominant model, homozygous model and heterozygous model (OR (95% CI)(0.796-0.965); OR (95% CI)=0.793(0.664-0.948); OR (95% CI)=0.755,(0.612-0.930); OR (95% CI)=0.820(0.679-0.991), respectively), but not to recessive model and over-dominant model (OR (95% CI)=0.882(0.770-1.010) and OR (95% CI)=1.009(0.897-1.148)).

Abstract
Background: Changes in the expression of cytokines as the result of the single nucleotide polymorphisms (SNPs), can affect the incidence of multiple sclerosis (MS). Objective: To investigate the relationship between the frequencies of interleukin-10 (IL-10)-1082 A/G (rs1800896) and CCR5-delta32 genotypes ...

Background: Changes in the expression of cytokines as the result of the single nucleotide polymorphisms (SNPs), can affect the incidence of multiple sclerosis (MS). Objective: To investigate the relationship between the frequencies of interleukin-10 (IL-10)-1082 A/G (rs1800896) and CCR5-delta32 genotypes and susceptibility to MS in the Iranian Azari population. Methods: IL-10-1082 A/G SNP and the CCR5-delta32 were genotyped in 152 patients suffering from MS and 242 healthy non-relatives by allele specific-PCR and simple PCR methods, respectively. Results: The frequencies of AA (37.6%) and AG (55.9%) genotypes of IL-10-1082 were significantly high in the control (p = 0.021) and MS patients (p = 0.015), respectively, with no statistical difference between these groups. There was no significant difference in the CCR5 gene based on the possession of wild/wild and wild/del32 genotypes between MS patients and the control group. The del32/del32 genotype was not seen in any of the investigated groups. Tobacco (cigarettes and hookahs) consumption was higher among the MS patients (p=0.004), and this has the potential to raise the risk of MS in both the individuals and their family. However, it had no significant relation with the frequency of different genotypes of the IL-10-1082 and the CCR5. Conclusion: Our finding conclude on possible role of AA genotype of IL-10 -1082 as a protective factor in MS.

Background: Schizophrenia is a disorder of the executive function of both sensory and central nervous system. Recent studies suggest that immune mechanisms play a role in the pathophysiology of this disease. The variations in cytokine concentrations have been associated with psychopathology and treatment of schizophrenia. Objective: To investigate the changes in serum concentrations of TNF- α, IL-10, and IL-2 in schizophrenic patients before and 40 days after treatment. Methods: In a case-control study, 26 schizophrenic patients and 26 healthy individuals were enrolled as the control group. PANSS scale questionnaire was used for diagnosis and assessing the severity of the disease. All patients were then treated with risperidone or clozapine for 40 days. Serum concentrations of TNF- α, IL-10 and IL-2 were measured by ELISA before and after treatment in both groups. Paired t-test and Independent t-test were used for comparison of data. Results: Comparison of TNF-α and IL-10 concentrations in patients before and after treatment revealed a significance decrease of TNF- α and increase of IL-10 concentrations (p=0.002, and p=0.008, respectively). Serum concentrations of IL-2 were lower than the detection limit of assay and were not detectable. In comparison with healthy controls, serum concentrations of TNF- α in schizophrenic patients were higher, while IL-10 concentrations were lower before treatment although the differences were not significant (p=0.291 and p=0.375, respectively). There was no correlation between cytokine concentrations and the positive and negative scale (PANSS). Also no significant difference in the admission, relapses, and duration of illness before and after treatment was observed. Conclusions: Increase of TNF- α and decrease of IL-10 may have an important role inpsychopathology of schizophrenia.

Background: Interleukin-10 (IL-10) is a Th2-type cytokine that inhibits macrophage activation. It is known that production of IL-10 is affected by its gene promoter polymorphisms. Objective: To investigate the relationship between IL-10 gene promoter polymorphisms and susceptibility to brucellosis. Methods: One hundred and ninety patients with brucellosis and 81 healthy animal husbandmen who owned infected animals and consumed their contaminated dairy products were included in this study. All individuals were genotyped for three bi-allelic IL-10 gene promoter polymorphisms at positions -1082(G/A), -819(T/C), and -592(A/C) using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The distribution of C alleles at positions -592 and -819 of IL-10 were significantly higher in patients than in the healthy animal husbandmen (p=0.034 and p=0.0086, respectively). IL-10 ATA single and double haplotypes were significantly higher in controls, compared to the patients (p= 0.0278 and p=0.013, respectively). Conclusion: According to the results higher frequency of C alleles at positions -592 and -819 of IL-10 in patients may be considered as genetic factors for susceptibility to brucellosis.
