Abstract
PURPOSE To investigate serum levels of interleukin (IL)-12 (Th1 cytokine), IL-27 (an immunomodulatory cytokine), IL-4 (suppressor of Th1-cell growth), IL-13 (a stimulatory signal for Th2 cytokines), and IL-33 (an epithelial cell-derived cytokine) and their relations with the disease activity in Behcet's Disease (BD). METHODS Four groups, each composed of 20 participants were enrolled in the study; active ocular BD (Group-A), ocular BD in remission (Group-B), nonocular BD in remission (Group-C) and healthy controls (Group-D). IL levels were compared between the study groups and their correlation with the disease activity parameters were analyzed. RESULTS IL-13 and IL-33 were higher in Group-A. IL-27 was lower in all BD groups. Additionally, IL-13 and IL-33 levels were positively correlated with disease activity parameters. CONCLUSION These findings show Th2 dominance in the active phase of BD. Besides, decreased levels of IL-27, and presumably, its protective anti-inflammatory effect in all study groups may exert a new pathologic finding in BD.

A functional promoter polymorphism in interleukin 12B gene is associated with an increased risk of ovarian endometriosis. Gene 2018; 666:27-31. [PMID: 29738836 DOI: 10.1016/j.gene.2018.04.082] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2018] [Revised: 04/27/2018] [Accepted: 04/27/2018] [Indexed: 01/07/2023]
Abstract
OBJECTIVE To explore the role of functional genetic variant of IL12B in the pathogenesis of ovarian endometriosis. STUDY DESIGN This study included 815 patients with ovarian endometriosis and 788 women in the control group. Two polymorphisms were genotyped by a method of polymerase chain reaction and ligase detection reaction. To assess the biological significance of polymorphisms, we detected the level of IL12p40 protein expression in patients' eutopic endometrial tissues using quantitative real-time polymerase chain reaction (qRT-PCR). RESULT(S) Compared with the CTCTAA/CTCTAA genotype, the GC/GC and GC/CTCTAA genotypes of rs17860508 could significantly increase the risk of ovarian endometriosis development (OR = 1.58, 95% CI = 1.19-2.09; OR = 1.37, 95% CI = 1.08-1.74, respectively). Moreover, the IL12B mRNA was expressed at significantly higher levels in the eutopic endometrial tissue of patients with the GC/GC genotype than in patients with the CTCTAA/CTCTAA genotype. However, the rs3212227 polymorphism may not be associated with a risk of ovarian endometriosis. CONCLUSION(S) The rs17860508 polymorphism in the IL12B promoter region may influence the risk of developing ovarian endometriosis by altering the endometrial expression of IL12B of in Northern Chinese women.

Abstract
Abstract
Background: Behcet’s disease (BD) is a chronic, inflammatory multisystemic condition of unknown etiology. Although the cause of BD is not clear, it is believed to be the result of an autoimmune process triggered by an infectious or environmental agent (possibly local to a geographic region) in a genetically predisposed individual.
Objective: To detail current knowledge of the role of microorganisms in the pathogenesis of BD and review the infectious etiology of this disease.
Methods: The review based on publication in SCOPUS, Science direct, and PubMed.
Results: A microbial infection has been implicated in the development of the disease to explain the strong inflammatory reactions observed, the activation of monocytes and macrophages, and the induction of proinflammatory cytokines and chemokines detected. Common factors linking some of the possible pathogenetic agents are extrinsically induced tissue stress or heat shock proteins, which react with host tissues and elicit significant T-helper type 1 cell responses.
Conclusion: Based on collected data, we conclude that the microorganisms discussed seem to participate and, at least in part, act as triggers during the course of BD. By clarifying the microbial associations of BD and finding its etiology, particularly the causative antigens leading to BD, it would be easier to suggest more effective treatment and preventive strategies for this disease.

The possible role of HSPs on Behçet's disease: a bioinformatic approach. Comput Biol Med 2012; 42:1079-85.

Abstract
Current evidence lends increasing support to immunoinflammatory mechanisms as one of the prime pathogenic processes involved in the development and progression of Behçet's disease (BD). It has been observed that most human beings have cellular and humoral reactions against microbial heat shock proteins (HSPs). The observation that eukaryotic and prokaryotic HSPs have high sequence similarity promoted the hypothesis that HSPs might be potential candidates for molecular mimicry and could act as potentially dangerous autoantigens. In this study, using bioinformatics tools, we examined the hypothesis that HSPs (evolutionarily conserved proteins), which are present in pathogenic and commensal organisms and their hosts, provide the stimulus that initiates BD in susceptible individuals. In this regards, the nucleotide and amino acid sequences of the human HSP 60 kDa and bacterial HSP 60 kDa deposited in the NCBI and PDB databases were subjected to analysis using bioinformatics tools, including The CLC Sequence Viewer and MEGA softwares. These data showed that the sequence homology between bacterial and self HSPs (leading to cross-reactivity and molecular mimicry phenomenon) may be associated with the development of the disease; and suggesting that microbial HSPs, which cross-react with host tissues and elicit significant immune responses are possible pathogenetic agents involved in the development and progression of BD.

Serum Interleukin-18 in Children with Henoch-Schönlein Purpura: A Promising Marker of Disease Activity? EUR J INFLAMM 2011.

Abstract
Henoch-Schönlein purpura (HSp) is the most common systemic vasculitis of childhood with typical skin involvement and concurrent signs involving joints, gastrointestinal tract, and kidney. HSp pathogenesis is still far from being completely understood, though a knotty cytokine complex is believed to contribute to its intimate processes. The aim of our evaluation is to establish the relationship between serum levels of interleukin (IL)-18 and disease outcome and establish its feasibility to provide a marker of disease activity or even a prognostic tool in clinical practice. We examined clinical/laboratory variables and serum IL-18 in 17 children hospitalized during a year for HSp, diagnosed by EULAR/PRINTO/PRES criteria; the same patients were re-evaluated after 6 months. All results were compared with 25 age-matched healthy controls. IL-12 and IL-6 were also evaluated in a cohort of the same patients and compared with controls. General and clinical variables (sex, edema of the extremities, gastrointestinal or renal complications, relapses and renal involvement at 6 months) had no relationship with cytokine levels. Serum IL-18 and IL-6 levels were found significantly increased at diagnosis in HSp patients when compared with healthy controls. After 6 months, serum IL-18 and IL-12 levels were significantly decreased in patients, while IL-12 and IL-6 levels were significantly increased compared to healthy controls. Though preliminary and expecting further confirmation on a larger sample, our data support the conclusion that serum IL-18 levels reflect HSp activity.

Abstract
The involvement of excessive T helper 1 (Th1) cell functions in the pathogenesis of Behçet's disease (BD) has been reported. We therefore studied Toll-like receptor (TLR)-expressing cells, which play important roles in innate immunity in patients with BD. Peripheral blood mononuclear cells (PBMC) of BD and healthy controls, and tissue specimens of intestinal BD and Crohn's disease (CD) were analysed for messenger RNA (mRNA) and protein expressions by reverse transcription-polymerase chain reaction and immunostaining respectively. PBMC of BD expressed TLR-2 and TLR-4 mRNA almost comparable with healthy controls. Intestinal lesions of BD expressed TLR-2 and TLR-4 mRNA consistently. In contrast, TLR-4 mRNA was expressed preferentially and TLR-2 mRNA was expressed less frequently in CD lesions. In intestinal samples of BD, TLR-2 and TLR-4 mRNA were detected in ileocaecal ulcer lesions, but not in unaffected sites of the same sample, indicating the association of the TLR expression with the disease manifestation of intestinal BD. TLR-2-expressing cells which were simultaneously cluster of distribution (CD)68-positive produced interleukin (IL)-12 in the lesions, indicating the participation of TLR-2-expressing cells in the Th1 skewed responses in vivo. As a possible ligand of TLR-2, in BD self-heat shock protein 60 was expressed in peripheral blood lymphocytes and intestinal tissues. Collectively, TLR-2-expressing cells as well as TLR-4-expressing cells accumulated in the intestinal lesions of BD. IL-12 produced by TLR-2-expressing cells may contribute to the induction of Th1-dominant immune responses in intestinal BD.
