Interleukin (IL)-37 belongs to the IL-1 cytokine family. It binds to IL-18Rα and recruits the orphan decoy IL-1R8. Emerging evidence shows that IL-37 is a key player in the regulation of inflammation, cellular differentiation, and proliferation. Altered IL-37 expression has been demonstrated in many inflammatory disease conditions, including asthma. In rheumatoid arthritis, IL-37 is involved in the regulation of proliferation, production of inflammatory mediators, and activation of inflammatory cells. Furthermore, this cytokine acts as a negative regulator of inflammation in inflammatory bowel disease...

Multiple sclerosis (MS) is a complex inflammatory, autoimmune disease of the central nervous system (CNS). The disease pathogenesis is not well defined yet. Cytokines have an important role in inflammation as characteristic feature of the disease. Janus kinase/signal transducers and activators of transcriptions (JAK/STAT) family promote cytokine-mediated cell activation. Failure in the JAK/STAT signaling pathway is associated with the pathological outcome in MS. In this study, we compared the expression levels of STAT5a and STAT6 genes in the blood of 50 relapsing-remitting MS (RR-MS) patients and 50 healthy controls by Taqman Quantitative Real-Time PCR in patients and healthy control group...

AZD8848 is a TLR7 agonist antedrug developed for administration by inhalation dosing for the treatment of allergic diseases, such as asthma. Allergic asthma is associated with increased levels of Th2 cytokines which are suppressed for extended periods by TLR7 agonists in a number of preclinical models of allergic airway inflammation. However, TLRs form a central part of innate immunity and their activation often results in proinflammatory responses. Whilst AZD8848's antedrug mechanism is designed to restrict its pharmacological action beyond the lung, the effect of chronic, supramaximal dosing to the target tissue has yet to be defined...

BACKGROUND: Characterizing blood profile of alopecia areata (AA) is not only important for treatment advancements, but also for possibly identifying peripheral biomarkers that will eliminate the need for scalp biopsies. We aimed to compare frequencies of skin homing (CLA(+) ) vs. systemic (CLA(-) ) "polar" CD4(+) and CD8(+) and activated T-cell subsets in AA vs. AD and control blood. METHODS: Flow cytometry was used to measure IFN-γ, IL-13, IL-9, IL-17, and IL-22 cytokines in CD4(+) and CD8(+) T-cells...

Background: Patients with human immunodeficiency virus/AIDS-associated cryptococcal meningitis (CM) frequently experience clinical deterioration, known as cryptococcosis-associated immune reconstitution inflammatory syndrome (C-IRIS), upon initiation of antiretroviral therapy (ART). The immunological mechanisms underlying C-IRIS are incompletely defined and no reliable predictive biomarkers exist. We investigated whether plasma or cerebrospinal fluid (CSF) levels of cytokines and chemokines predicted C-IRIS and are potential predictive biomarkers...

BACKGROUND: Differential diagnosis between primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) is sometimes difficult as nephrotic syndrome is the main clinical symptom in both diseases. OBJECTIVES: This study has attempted to evaluate the urinary excretion of Th1 and Th2 cytokines as potential biomarkers in distinguishing the two types of nephrotic syndrome, and predicting outcome of renal function. PATIENTS AND METHODS: Thirty-six patients with FSGS (M/F 22/14, Age; 41...

Periostin is a protein that plays a key role in development and repair within the biological matrix of the lung. As a matricellular protein that does not contribute to extracellular matrix structure, periostin interacts with other extracellular matrix proteins to regulate the composition of the matrix in the lung and other organs. In this review, we discuss the studies exploring the role of periostin to date in chronic respiratory diseases, namely asthma and idiopathic pulmonary fibrosis. Asthma is a major health problem globally affecting millions of people worldwide with significant associated morbidity and mortality...

Until the past year, our therapeutic armamentarium for treating atopic dermatitis (AD) was still primarily topical corticosteroids and, for more severe disease, systemic immunosuppressants. The pipeline of more targeted topical and systemic therapies is expanding based on our growing understanding of the mechanism for AD and is particularly focused on suppressing the skewed immune activation. Most agents are in phase 2 clinical trials. Crisaborole, a topical phosphodiesterase 4 (PDE4) inhibitor, became available in late 2016 in the United States for mild-to-moderate AD, with other PDE4 inhibitors, an agonist of the aryl hydrocarbon receptor, Janus kinase inhibitors, and commensal organisms also in trials for topical application...

INTRODUCTION: Bronchiectasis is a heterogeneous entity, taking into account clinical characteristics, inflammatory response, effectiveness of treatment and frequency of exacerbations. In stable state non-cystic fibrosis (non-CF) bronchiectasis, little is known about non-invasive techniques used for evaluating airway inflammation in obstructive airway diseases. OBJECTIVES: We sought to evaluate the associations between induced sputum and clinical/radiologic characteristics, and the differences between biomarkers expressing Th1 and Th2 response in patients with non-CF bronchiectasis and to compare our findings with a previously studied population of patients with asthma and COPD...

Asthma is a common disease in both high and lower income countries that starts early and persists often for life. A correct and accurate diagnosis, treatment and follow-up during childhood are essential for a better understanding of adult asthma and avoiding over- or under-treatment. Th2 inflammation in children with asthma symptoms is usually assessed by measuring with serum total IgE, blood eosinophilia and FeNO levels that may help to predict asthma, particularly in those infants and young children in whom lung function tests are difficult to perform...

Leukemic cells can induce defective expression of soluble factors and change marrow cytokine profile, leading to aberrant cell signaling, cell fixation and cell proliferation in bone marrow. T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disorder which accounts for 15% of pediatric ALL. To evaluate the contribution of immunological factors on T-ALL survival, we measured Th1, Th2, Th17 cytokines and soluble HLA-G (sHLA-G) levels in bone marrow from 32 Brazilian children at diagnosis (D0), after induction (D19) and after consolidation (D49) of the chemotherapy phase...

Allergen-specific type 2 helper T (TH2) cells play a central role in initiating and orchestrating the allergic and asthmatic inflammatory response pathways. One major factor limiting the use of such atopic disease-causing T cells as both therapeutic targets and clinically useful biomarkers is the lack of an accepted methodology to identify and differentiate these cells from overall nonpathogenic TH2 cell types. We have described a subset of human memory TH2 cells confined to atopic individuals that includes all allergen-specific TH2 cells...

Mycobacterium tuberculosis (Mtb) and helminth infections elicit antagonistic immune effector functions and are co-endemic in several regions of the world. We therefore hypothesized that helminth infection may influence Mtb-specific T-cell immune responses. We evaluated the cytokine profile of Mtb-specific T cells in 72 individuals with pulmonary TB disease recruited from two Sub-Saharan regions with high and moderate helminth burden i.e. 55 from Tanzania (TZ) and 17 from South Africa (SA), respectively. We showed that Mtb-specific CD4 T-cell functional profile of TB patients from Tanzania are primarily composed of polyfunctional Th1 and Th2 cells, associated with increased expression of Gata-3 and reduced expression of T-bet in memory CD4 T cells...

Enteric redmouth disease (ERM or yersiniosis) is one of the most important diseases of salmonids and leads to significant economic losses. It is caused by the Gram-negative bacterium Yersinia ruckeri but can be controlled by bacterin vaccination. The first commercial ERM vaccine was licenced in 1976 and is one of the most significant and successful health practices within the aquaculture industry. Although ERM vaccination provides complete protection, knowledge of the host immune response to the vaccine and the molecular mechanisms that underpin the protection elicited is limited...

Drug-induced autoimmunity (DIA) refers to a group of adverse drug reactions, and they remain unpredictable largely due to the limited understanding of the mechanisms involved. There is evidence that procainamide can cause autoimmune reactions in humans but the mechanisms involved remain unclear. To examine the cellular and genetic factors involved in the procainamide-induced autoimmune response, we compared rats that are genetically T-helper (Th)2-predisposed (Brown Norway (BN)), Th1-predisposed (Lewis (LEW)) or not genetically predisposed (Sprague Dawley (SD))...

Allergic asthma is a chronic respiratory disease with a prevalent T helper (Th2)-mediated immune reaction. Crocin, the major bioactive constituent of saffron, has been reported in multiple studies to have numerous pharmacological activities, including prominent anti-oxidant activities. In the current study, the anti-asthmatic potential of crocin was evaluated. Adult male Swiss Albino mice were administered 10mg of ovalbumin (OVA) mixed with 1mg of aluminum hydroxide intraperitoneally on days 0 and 7 and were administered crocin (25mg/kg) orally daily for 16days...

X-linked adrenoleukodystrophy (X-ALD) is an inherited disease characterized by progressive inflammatory demyelization in the brain, adrenal insufficiency, and an abnormal accumulation of very long chain fatty acids (VLCFA) in tissue and body fluids. Considering that inflammation might be involved in pathophysiology of X-ALD, we aimed to investigate pro- and anti-inflammatory cytokines in plasma from three different male phenotypes (CCER, AMN, and asymptomatic individuals). Our results showed that asymptomatic patients presented increased levels of pro-inflammatory cytokines IL-1β, IL-2, IL-8, and TNF-α and the last one was also higher in AMN phenotype...

Allergic airways inflammation in asthma is characterized by an airway epithelial gene signature composed of POSTN, CLCA1, and SERPINB2 This Th2 gene signature is proposed as a tool to classify patients with asthma into Th2-high and Th2-low phenotypes. However, many asthmatics smoke and the effects of cigarette smoke exposure on the epithelial Th2 gene signature are largely unknown. Therefore, we investigated the combined effect of IL-13 and whole cigarette smoke (CS) on the Th2 gene signature and the mucin-related genes MUC5AC and SPDEF in air-liquid interface differentiated human bronchial (ALI-PBEC) and tracheal epithelial cells (ALI-PTEC)...

BACKGROUND: Interleukin 17 (IL-17) is produced by highly inflammatory Th17 cells and has been implicated in pathophysiology of depression. IL-17 putatively disrupts the blood brain barrier and affects dopamine synthesis whereas dopamine has been shown to decrease Th17 cell-mediated immune response. Nevertheless, whether IL-17 can predict differential treatment outcome with antidepressants modulating dopaminergic transmission is unknown. METHODS: IL-17 and other T cell and non-T cell markers (Th1, Th2 and non-T cell markers) were measured with the Bioplex Pro™ human cytokine 27-plex kit in the Combining Medications to Enhance Depression Outcomes (CO-MED) trial participants who provided baseline plasma and were treated with either bupropion plus escitalopram (bupropion-SSRI), escitalopram plus placebo (SSRI monotherapy), or venlafaxine plus mirtazapine (n=166)...
