Abstract
IL-39 (Interleukin-39) is a heterodimeric cytokine composed of IL-23p19 and EBI3 (Epstein-Barr virus-induced gene 3) subunits. Despite the evidence that correlates the role of IL-39 in regulating inflammation, its expression in the intestinal microenvironment of IBD (inflammatory bowel disease) patients is still unknown. Thus, this work was focused on characterizing relative mRNA (messenger RNA) IL-39 expression and intestinal synthesis in IBD patients. This study includes 37 patients diagnosed with ulcerative colitis (UC), 15 with Chron's disease (CD), and 22 controls. Gene expression of IL-39 subunits (IL-23p19/EBI3) was measured by RT-PCR (real time polymerase chain reaction). Intestinal synthesis was evaluated by immunohistochemistry and serum levels by ELISA. Statistical analysis was done using Prism GraphPad V6. Relative mRNA IL-39 expression was increased in patients with active UC and active CD compared to the remission UC, remission CD, and control group. High levels of relative mRNA expression of IL-39 (IL-23p19 subunit) were associated with histological activity. IHQ analysis showed increased IL-39 production in mucosa, submucosa, muscular, and serosa layer of patients with active disease. IL-39 serum production was increased in patients with UC. IL-39 gene's upregulation was found in patients with active IBD and was associated with severe histological activity in UC. This is the first report regarding the role of IL-39 in patients with IBD. The findings suggest that IL-39 might play a role as an inflammatory mediator in active IBD and could be considered a new alternative in treating this condition.

The relationship between extreme inter-individual variation in macrophage gene expression and genetic susceptibility to inflammatory bowel disease. Hum Genet 2024; 143:233-261.

Abstract
The differentiation of resident intestinal macrophages from blood monocytes depends upon signals from the macrophage colony-stimulating factor receptor (CSF1R). Analysis of genome-wide association studies (GWAS) indicates that dysregulation of macrophage differentiation and response to microorganisms contributes to susceptibility to chronic inflammatory bowel disease (IBD). Here, we analyzed transcriptomic variation in monocyte-derived macrophages (MDM) from affected and unaffected sib pairs/trios from 22 IBD families and 6 healthy controls. Transcriptional network analysis of the data revealed no overall or inter-sib distinction between affected and unaffected individuals in basal gene expression or the temporal response to lipopolysaccharide (LPS). However, the basal or LPS-inducible expression of individual genes varied independently by as much as 100-fold between subjects. Extreme independent variation in the expression of pairs of HLA-associated transcripts (HLA-B/C, HLA-A/F and HLA-DRB1/DRB5) in macrophages was associated with HLA genotype. Correlation analysis indicated the downstream impacts of variation in the immediate early response to LPS. For example, variation in early expression of IL1B was significantly associated with local SNV genotype and with subsequent peak expression of target genes including IL23A, CXCL1, CXCL3, CXCL8 and NLRP3. Similarly, variation in early IFNB1 expression was correlated with subsequent expression of IFN target genes. Our results support the view that gene-specific dysregulation in macrophage adaptation to the intestinal milieu is associated with genetic susceptibility to IBD.

Nussrat SW, Ad'hiah AH. Interleukin-39 is a novel cytokine associated with type 2 diabetes mellitus and positively correlated with body mass index. Endocrinol Diabetes Metab 2023; 6:e409. [PMID: 36757903 PMCID: PMC10164431 DOI: 10.1002/edm2.409] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 01/27/2023] [Accepted: 01/29/2023] [Indexed: 02/10/2023] Open
Abstract
INTRODUCTION It is suggested that cytokines play a key role in the pathogenesis of type 2 diabetes mellitus (T2DM). Therefore, this study explored two recently discovered cytokines, interleukin (IL)-37 (anti-inflammatory) and IL-39 (pro-inflammatory), in T2DM due to limited data in this context. METHODS Serum IL-37 and IL-39 levels were determined in 106 T2DM patients and 109 controls using enzyme-linked immunosorbent assay kits. RESULTS Serum levels (median and interquartile range) of IL-37 (79 [47-102] vs. 60 [46-89] ng/L; probability [p] = .04) and IL-39 (66 [59-69] vs. 31 [19-42] ng/L; p < .001) were significantly elevated in T2DM patients compared to controls. As indicated by the area under the curve (AUC), IL-39 (AUC = 0.973; p < .001) was more predictable for T2DM than IL-37 (AUC = 0.582; p = .039). Elevated levels of IL-39 were significantly associated with T2DM (odds ratio = 1.30; p < .001), while IL-37 did not show this association. Classification of IL-37 and IL-39 levels by demographic and clinical characteristics of patients revealed some significant differences including gender (IL-39), body mass index (BMI; IL-37 and IL-39) and diabetic neuropathy (IL-39). BMI was positively correlated with IL-39 (correlation coefficient [rs ] = 0.27; p = .005) and glycosylated haemoglobin (rs = 0.31; p = .001), and negatively correlated with age at onset (rs = -0.24; p = .015). CONCLUSIONS IL-37 and IL-39 levels were elevated in the serum of T2DM patients. Besides, IL-39 is proposed to be a novel cytokine associated with T2DM and positively correlated with BMI.

Abstract
Brucellosis is significantly influenced by the interactions between the causative Brucella bacteria and host immunity. Recently identified cytokines have been described for their immunomodulatory effects in numerous inflammatory, autoimmune and infectious diseases. Some of them are new members of cytokine superfamilies, including several members of the IL-12 superfamily (IL-35, IL-39). The major purpose of the present study was to investigate the role of these new immunomodulatory cytokines in Brucella infections. The levels of IL-35 and IL-39 in the serum of 40 acute and 40 chronic brucellosis patients and 40 healthy controls were measured by ELISA. The mRNA levels of IL-35 and IL-39 in PBMCs were detected by RT-qPCR. Both IL-35 and IL-39 serum concentrations were significantly higher in healthy control subjects than in brucellosis patients, and IL-35 and IL-39 serum levels of chronic brucellosis patients were higher than those of acute cases. It was also found that the expression of Ebi3/IL-12A (IL-35 genes) and Ebi3/IL-23A (IL-39 genes) was upregulated in chronic brucellosis patients compared to healthy controls. Moreover, the expression of the Ebi3/IL-12A and Ebi3/IL-23A genes was lower in patients with acute brucellosis than in patients with chronic brucellosis. Overall, this study showed that IL-35 and IL-39 are positively correlated in brucellosis and significantly decreased during the disease. Significantly lower levels of IL-35 and IL-39 in acute brucellosis than in chronic brucellosis and healthy controls suggest that these cytokines may play a key role in suppressing the immune response to brucellosis and its progression to chronicity.

Abstract
Introduction and Aim: The pro-inflammatory cytokine IL-39, a member of the IL-12 family plays a key role in the inflammatory response by modulating immune cell activity and inflammation. A literature search shows no study undertaken for the effect of IL-39's on arthritis so far. Hence, the purpose of this study was to investigate the role of IL-39 in rheumatoid arthritis.
Materials and Methods: This study involved 80 patients with rheumatoid arthritis registered at the Rheumatology Clinic at Baghdad teaching hospital. The patients were divided into three groups based on treatments received. Group 1 included patients who were not on any treatment for arthritis, Group 2 with patients on hydroxychloroquine and or prednisone treatment, and Group 3 that received Enbrel® (etanercept) and HUMIRA® (adalimumab) treatment for rheumatoid arthritis. A control group was included in the study. Patients in all groups were assessed for their serum IL-39 concentration, C - reactive protein, Anti-cyclic citrullinated peptide antibody (ACCP) and ESR.
Results: The patient age and BMI were not significantly different between the groups receiving treatment for Rheumatoid arthritis. A significant increase in the interleukin 39 concentration was observed in treatment groups (G1, G2, G3) as compared to normal healthy controls regardless of whether they were positive or negative for the anti-CCP test.
Conclusion: This study showed that the serum interleukin IL-39 levels significantly increased in patients diagnosed with rheumatoid arthritis thus suggesting that IL-39 could be considered as a potential inflammatory biomarker of RA.

Abstract
Abstract
Objectives
IL-23p19/Ebi3 (IL-39) was described as a new IL-12 family member. The aim of this study is to evaluate the gingival crevicular fluid (GCF) IL-39 levels in periodontal diseases and health and to correlate them to GCF levels of IL-1β and periostin.
Materials and methods
Sixty-six adult patients were included in the study. The study design was comprised of three groups, each containing 22 individuals: the periodontally healthy (PH), gingivitis (G), and periodontitis (P) groups. The clinical periodontal parameters were recorded and GCF samples were collected from the participants. GCF interleukin (IL)-39, IL-1β, and periostin levels were examined using the enzyme-linked immunosorbent assay.
Results
GCF IL‑1β, periostin, and IL-39 levels were higher in the P and G groups than in the PH group (p < 0.001). Positive correlations were detected between all GCF biochemical parameters and clinical periodontal parameters (p < 0.05). In the multivariate generalized linear regression analysis, the P (β = 37.6, 95% CI = 22.9–52.4) and G (β = 28.4, 95% CI = 15.8–41) groups were associated with GCF IL-39 levels (p < 0.001).
Conclusion
IL-39 levels were elevated in the presence of periodontal disease paralleling the increase in IL‑1β and periostin levels. IL-39 may have a role in the periodontal inflammation process.
Statement of clinical relevance
IL-39, a new cytokine from the IL-12 family, can be a possible predictor marker of periodontal diseases.

Abstract
Cell regenerative therapy is a modern solution for difficult-to-heal wounds. Keratinocytes, the most common cell type in the skin, are difficult to obtain without the creation of another wound. Stem cell differentiation towards keratinocytes is a challenging process, and it is difficult to reproduce in chemically defined media. Nevertheless, a co-culture of keratinocytes with stem cells usually achieves efficient differentiation. This systematic review aims to identify the secretions of normal human keratinocytes reported in the literature and correlate them with the differentiation process. An online search revealed 338 references, of which 100 met the selection criteria. A total of 80 different keratinocyte secretions were reported, which can be grouped mainly into cytokines, growth factors, and antimicrobial peptides. The growth-factor group mostly affects stem cell differentiation into keratinocytes, especially epidermal growth factor and members of the transforming growth factor family. Nevertheless, the reported secretions reflected the nature of the involved studies, as most of them focused on keratinocyte interaction with inflammation. This review highlights the secretory function of keratinocytes, as well as the need for intense investigation to characterize these secretions and evaluate their regenerative capacities.

Abstract
Polycyclic aromatic systems have been considered good biological probes, but some may also be good scaffolds for drug development. In this study, a series of benzobis(imidazole) derivatives were identified as STAT3 signal inhibitors, among which compound 24 showed significant inhibition of IL-6 induced JAK/STAT3 signalling pathway activation. Moreover, 24 inhibited cancer cell growth and migration, and induced cell apoptosis as well as cycle arrest in human hepatocellular carcinoma cells (HepG2) and oesophageal carcinoma cells (EC109). Compound 24 also displayed obvious antitumor activity in a mouse HepG2 cell xenograft tumor model without affecting the body weight. These results confirmed that 24 was a potential STAT3 signal inhibitor with certain antitumor activity.

Abstract
Interleukin 12 (IL-12) family cytokines are secreted proteins that regulate immune responses. Each family member is a heterodimer and nature uses shared building blocks to assemble the functionally distinct IL-12 cytokines. In recent years we have gained insights into the molecular principles and cellular regulation of IL-12 family biogenesis. For each of the family members, generally one subunit depends on its partner to acquire its native structure and be secreted from immune cells. If unpaired, molecular chaperones retain these subunits in cells. This allows cells to regulate and control secretion of the highly potent IL-12 family cytokines. Molecular insights gained into IL-12 family biogenesis, structure, and function now allow us to engineer IL-12 family cytokines to develop novel immunotherapeutic approaches.

Abstract
Background Interleukin (IL)‐39 is a novel member of IL‐12 cytokine family, but its role in autoimmune thyroid diseases (AITD) is unclear. The aim of the present study was to determine serum levels of IL‐39 in Hashimoto's thyroiditis (HT) and Graves' disease (GD) patients. Methods A total of 48 patients with HT, 50 patients with GD, and 45 healthy controls (HCs) were recruited for this study. Levels of serum IL‐39 were determined by ELISA. Results Compared with HC group, levels of serum IL‐39 in patients with HT (p < 0.05) and GD (p < 0.01) were drastically reduced. Among patients with HT, serum IL‐39 levels had a positive correlation with white blood cell count (WBC) count and free triiodothyronine level. Among patients with GD, the levels of IL‐39 in serum were positively correlated with WBC count and C‐reactive protein levels. Conclusions IL‐39 may be a new potential predictor for patients with HT and GD.

Abstract
Interleukin (IL) 23 (p19/p40) plays a critical role in the pathogenesis of psoriasis and is upregulated in psoriasis skin lesions. In clinical practice, anti-IL-23Ap19 antibodies are highly effective against psoriasis. IL-39 (p19/ Epstein-Barr virus-induced (EBI) 3), a newly discovered cytokine in 2015, shares the p19 subunit with IL-23. Anti-IL-23Ap19 antibodies may bind to IL-39; also, the cytokine may contribute to the pathogenesis of psoriasis. To investigate IL23Ap19- and/or EBI3-including cytokines in psoriatic keratinocytes, we analyzed IL-23Ap19 and EBI3 expressions in psoriasis skin lesions, using immunohistochemistry and normal human epidermal keratinocytes (NHEKs) stimulated with inflammatory cytokines, using quantitative real-time polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), and liquid chromatography-electrospray tandem mass spectrometry (LC-Ms/Ms). Immunohistochemical analysis showed that IL-23Ap19 and EBI3 expressions were upregulated in the psoriasis skin lesions. In vitro, these expressions were synergistically induced by the triple combination of tumor necrosis factor (TNF)-α, IL-17A, and interferon (IFN)-γ, and suppressed by dexamethasone, vitamin D3, and acitretin. In ELISA and LC-Ms/Ms analyses, keratinocyte-derived IL-23Ap19 and EBI3, but not heterodimeric forms, were detected with humanized anti-IL-23Ap19 monoclonal antibodies, tildrakizumab, and anti-EBI3 antibodies, respectively. Psoriatic keratinocytes may express IL-23Ap19 and EBI3 proteins in a monomer or homopolymer, such as homodimer or homotrimer.
