Interleukin-4 (IL-4) has recently been shown to regulate NK cell function, although its role in the regulation of NK cell function in cancer patients has not been clarified. The aim of this study was to investigate the effect of IL-4 on the function and the receptor characteristics of CD16-defined NK cells and their cytotoxic CD16bright and regulatory CD16dim subsets. Peripheral blood lymphocytes obtained from 36 metastatic melanoma (MM) patients treated for 18 h with 10 ng/mL IL-4 were evaluated for NK cell cytotoxicity using the radioactive 51chromium release assay. Expression of the activating receptors NKG2D and CD161, as well as the inhibitory receptors CD158a and CD158b, was analyzed on CD3-CD16+ NK cells and their subsets by flow cytometry. IL-4 induced significant in vitro enhancement of NK cell activity, as well as increased expression of the CD107a degranulation marker, by CD3-CD16dim NK cells. NKG2D expression was also increased on CD3-CD16+ cells by IL-4 with no alteration of the expression of CD161 and inhibitory KIR receptors. Although in vitro treatment with IL-4 increased both the expression of NKG2D and the cytotoxicity of NK cells, it had no detectable effect on the transcription of the TGF-β gene in NK cells of MM patients. The IL-4-induced NK cell cytotoxicity and increased activating NKG2D receptor expression may indicate an important antitumor effect of IL-4 with a potential application for immunotherapy of MM patients.","PeriodicalId":11749,"journal":{"name":"European cytokine network","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2020-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38670511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is no specific drug for preventing the cytokine release syndrome (CRS) caused by COVID-19. Indeed, interleukin 6 (IL-6) has been highlighted for its many biological functions, such as immune regulation, inflammatory response, and metabolism. Therapeutic blockade of the IL-6 signaling pathway is expected to reduce the excessive immune reponse observed in COVID-19. Currently, the IL-6 receptor antagonists tocilizumab and sarilumab, have been adopted for preventing CRS during the progression of COVID-19, and remarkable beneficial effects were observed by using these humanized monoclonal antibodies.

A multivariable logistic regression with metabolic syndrome as the dependent variable was performed with inflammatory biomarkers and other parameters involved in NAFLD as independent variables.Results: Chronic kidney disease (CKD), retinopathy, body mass index (BMI), diabetes duration, alanine aminotransferase (ALT), fatty liver index (FLI), and CPR levels were associated with metabolic syndrome in univariate analysis.

No other inflammatory biomarkers showed an association with metabolic syndrome in type 1 diabetes.

IL-27 Genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and the IL-27 serum levels were measured using enzyme-linked immunosorbent assay (ELISA).

Significantly higher frequencies of AG and GG genotypes and G allele were observed in total and male patients with an active form of BD.

Forty-four patients with a PCR-proven diagnosis of COVID-19 were included. Extensive cellular (leukocytes and T-lymphocyte subsets) and serological immune profiling (cytokines, soluble cell surface molecules, and SARS-CoV-2 antibodies) was performed at hospital admission and every 3-4 days during hospitalization. Measurements and disease outcome were compared between patients with an unfavorable (IC admission and/or death) and favorable (all others) outcome. Patients with an unfavorable outcome had higher leukocyte numbers at baseline, mostly due to increased neutrophils, whereas lymphocyte and monocyte numbers were reduced. CRP, IL-6, CCL2, CXCL10, and GM-CSF levels were higher at baseline in the unfavorable group, whereas IL-7 levels were lower. SARS-CoV-2 antibodies were more frequently absent in the unfavorable group. Longitudinal analysis revealed delayed kinetics of activated CD4 and CD8 T-lymphocyte subsets in the unfavorable group. Furthermore, whereas CRP, IL-6, CXCL10, and GM-CSF declined in the favorable group, these cytokines declined with delayed kinetics, remained increased, or even increased further in the unfavorable group. Our data indicate a state of increased innate immune activation in COVID19-patients with an unfavorable outcome at hospital admission, which remained over time, as compared with patients with a favorable outcome.","PeriodicalId":11749,"journal":{"name":"European cytokine network","volume":"31 4","pages":"154-167"},"PeriodicalIF":2.8,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7937051/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25418360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several antidiabetic drugs have been approved, none of them are adequately effective in the long-term management of T2D. Therefore, novel treatment options are needed for disease prevention or delaying disease progression. Bruton's tyrosine kinase (BTK) is a cytoplasmic enzyme that plays a role in B-cell differentiation and proliferation, and therapeutic targeting of BTK offers protection against chronic diseases. In this study, we analyzed BTK expression and its correlation with inflammatory mediators in patients with diabetes and obesity. The levels of BTK were significantly high in visceral adipose tissues of patients (p < 0.01) with diabetes and obesity compared with healthy controls. Additionally, a positive correlation was noted between the expression of BTK and the inflammatory cytokine genes TNF-α, INF-γ, IL-6, and IL-1 (p < 0.01) in adipose tissue. In insulin-resistant HepG2 cells (IR-HepG2), ibrutinib inhibited BTK expression in parallel with inflammatory genes, and increased insulin signaling and activity compared with untreated IR-HepG2 cells. Additionally, ibrutinib-treated IR-HepG2 cells showed increased glucose uptake compared with untreated IR-HepG2 cells. These results provide evidence that BTK inhibition may serve as a novel therapeutic strategy for the treatment of T2D. These findings also uncover the novel role of BTK in diabetes and insulin resistance; however, further in vivo studies are required prior to translating the findings into clinical settings.","PeriodicalId":11749,"journal":{"name":"European cytokine network","volume":"31 4","pages":"168-179"},"PeriodicalIF":2.8,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25418361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
