OBJECTIVES: The objective of this study was to investigate 2 key dimensions of socioeconomic status (SES)-prestige and resources-and their associations with immune, behavioral, and clinical outcomes in childhood asthma. METHODS: Children ages 9 to 17 years with a physician's diagnosis of asthma (N = 150), and one of their parents participated in this study. Children and parents completed interviews and questionnaires about SES (prestige = parent education; resources = family assets), environmental exposures, and clinical asthma measures...

IgG4-related disease (IgG4-RD) is a systemic disease characterized by elevated serum IgG4 levels and a strong infiltration of IgG4-positive plasma cells in various organs. IgG4-RD patients also frequently suffer from allergic diseases, including asthma and atopic dermatitis. It is well known that T helper type 2 (Th2) cells have an important role in the initiation of allergic diseases, and Th2 cytokines such as interleukin (IL)-4 and IL-13 promote class switching to IgG4. Therefore, IgG4-RD is considered to be a Th2-predominant disease...

BACKGROUND: Farm exposure protects against development of allergies early in life. At 4.5 years, protection against asthma by farm-milk exposure was partially mediated by regulatory T-cells (Tregs). The aim of this study was to investigate the critical time window of the "asthma-protective" farm effect via Tregs during childhood immune maturation. METHODS: Tregs were assessed longitudinally at 4.5 and 6 years in 111 children (56 farm, 55 reference children) from the PASTURE/EFRAIM birth cohort (flow-cytometry)...

INTRODUCTION: In the pathogenesis of asthma, an imbalance between helper T (Th) 1/Th2 and Th17/Treg cells is believed to play a key role in asthmatic inflammatory responses. Some studies indicated that zinc deficiency increases inflammatory factor production and worsens asthma. However, the effects of zinc on T cell profiles to reduce inflammatory response remain unclear Objectives: We investigated the beneficial effects of zinc on isolated cell populations and cytokine levels from patients with asthma...

Proinflammatory cytokines are thought to modulate pathogeneses of various inflammatory bowel diseases (IBDs). Thymic stromal lymphopoietin (TSLP), which has been studied in various allergic diseases such as asthma, atopic dermatitis (AD) and eosinophilic esophagitis (EoE), has been less considered to be involved in IBDs. However, mucosal dendritic cells (DCs) induced by various cytokines including TSLP were reported to cause polarization of T cell toward Th2 response, the differentiation of regulatory T-cell (Treg), and secretion of IgA by B cells...

BACKGROUND: Acute worsening of asthma symptoms (exacerbation) is predominantly triggered by respiratory viruses, with influenza causing the most severe exacerbations. The lack of an adequate animal model hampers mechanistic insight and the development of new therapeutics. AIM: We developed and characterized a robust, consistent and reproducible mouse model of severe exacerbation of chronic allergic asthma. METHODS: Chronic allergic airway inflammation was induced following a house dust mite (HDM)-sensitization protocol...

BACKGROUND: Asthma is prone to Th2-mediated chronic airway inflammation. Interleukin-27 (IL-27) is a member of the IL-12 family that promotes the differentiation of Th1 cells and inhibits Th2 cells. We use human/mouse CD4(+) T cells to see whether IL-27 could inhibit IL-4 production in vitro and then observe whether IL-27 administration could alleviate allergic airway inflammation in vivo by mice asthma model. METHODS: We isolated and cultured CD4(+) T cells from healthy humans and mice to test whether IL-27 could inhibit IL-4 production under different conditions...

Clinical and immunologic tolerance are hallmarks of successful allergen immunotherapy (AIT). Clinical benefits such as reduced symptoms, pharmacotherapy intake and improvement of quality of life persist following cessation of treatment. Successful AIT is associated with suppression of allergic inflammatory cells such as mast cells, eosinophils and basophils in target organs. Furthermore, AIT down-regulates type 2 innate lymphoid cells and allergen-specific type 2 T-helper (Th2) cells. The immunologic tolerant state following AIT is associated with the induction of distinct phenotypes of regulatory T-cells (T-regs) including interleukin (IL)-10-, IL-35- and transforming growth factor (TGF)-β- producing T-regs and FoxP3(+) T-regs...

Predominant T helper (Th)2 and impaired Th1 cell polarization has a crucial role in the development of asthma. Cluster of differentiation (CD)38 is associated with the increased release of interleukin (IL)‑12 from dendritic cells (DCs) and DC‑induced Th1 cell polarization. However, whether CD38 expression affects DC function in asthma development remains unknown. In the current study, adenoviruses were constructed containing the murine CD38 gene. Overexpression of CD38 protein level in DCs induced from bone‑marrow derived DCs (BMDCs) by recombinant mouse granulocyte macrophage colony‑stimulating factor and IL‑4 was achieved through 24 h adenovirus infection...

BACKGROUND: Although some patients with obstructive lung disease (OLD) have features of both asthma and chronic obstructive pulmonary disease (COPD), the term "asthma-COPD overlap syndrome (ACOS)" was coined only relatively recently. However, there are gaps in our knowledge of the clinical features, pathogenesis, prognosis, and management of ACOS patients. OBJECTIVES: To review the literature on ACOS to determine the extent to which the clinical features, pathologic mechanisms, clinical outcomes, and current therapeutic approaches for ACOS differ from those in patients with asthma alone or COPD alone...

Asthma is a disease that currently affects approximately 300 million people worldwide. It is generally viewed as an allergic disease and can manifest itself in a variety of phenotypes. Two of its main phenotypes routinely assessed at the clinic include airway hyperresponsiveness and IgE production. They can be measured in a non-invasive manner and have been used for genetic studies. However, the genetic complexity of asthma and its phenotypes makes it difficult to map their genetic contributors. Though human studies have been successful at mapping candidate genes for asthma phenotypes, they require large sample sizes and proper segregation of the population to control for potential confounding factors...

IgE-mediated allergies, in particular allergic rhino-conjunctivitis and asthma, have reached epidemic proportions, affecting about one third of the population in developed countries. The most effective treatment for allergies is specific immunotherapy (SIT), which involves the injection of increasing doses of an allergen extract to allergic individuals. The current form of SIT was first introduced 1911 and recently celebrated its 100(th) birthday for the treatment of hay fever. The concept of this therapy at the time was straight-forward, since it was believed that pollen contained toxins against which the patient could be vaccinated...

ETHNOPHARMACOLOGICAL RELEVANCE: Over the past few decades, there have been significant scientific advances leading to improved understanding of asthma as a disease and treatment providing immediate relief. However, prevention of recurrent attacks, exacerbations and disease cure remains a challenge. Ayurveda refers to bronchial asthma as Tamaka Swasa and it is well explained in Charaka Samhita. Management of asthma in Ayurveda includes removal of vitiated Kapha through Shodhana, Shamana procedures, herbal and herbomineral formulations in addition to advising a healthy lifestyle and diet...

Extensive research into the therapeutics of asthma has yielded numerous effective interventions over the past few decades. However, adverse effects and ineffectiveness of most of these medications especially in the management of steroid resistant severe asthma necessitate the development of better medications. Numerous drug targets with inherent airway smooth muscle tone modulatory role have been identified for asthma therapy. This article reviews the latest understanding of underlying molecular aetiology of asthma towards design and development of better antiasthma drugs...

Vitamin D should not be considered only as a vitamin. It has a relevant role in many functions of body regulation, both skeletal and extra skeletal and this makes vitamin D an essential element for a healthy status. This is well explained by a ubiquitous presence of vitamin D receptors. Nowadays extra skeletal effects have a more interesting impact in medical practice. The paracrine and autocrine action of vitamin D has a pivotal role for these effects. The activation of the cellular transcriptional process leads to the expression of beta-defensin and cathelicidin, activating the Th1 pathway, related to innate immunity against bacteria...

Oridonin is an extract obtained from a traditional Chinese medicinal herb, Xihuangcao. Previous studies have demonstrated that Oridonin exerts various pharmaceutical effects, such as anti‑tumor and immunosuppressive effects, as well as modulating cytokine balance. The present study identified that Oridonin could regulate the Th1/Th2 cytokine balance in mice. However, as the anti‑asthmatic effect of Oridonin is currently unknown a mouse model of asthma was used in the present study. BALB/c mice were sensitized using ovalbumin (OVA), then the sensitized mice were treated with Oridonin prior to OVA challenge...

Data integration has become a useful strategy for uncovering new insights into complex biological networks. We studied whether this approach can help to delineate the signal transducer and activator of transcription 6 (STAT6)-mediated transcriptional network driving T helper (Th) 2 cell fate decisions. To this end, we performed an integrative analysis of publicly available RNA-seq data of Stat6-knockout mouse studies together with STAT6 ChIP-seq data and our own gene expression time series data during Th2 cell differentiation...

BACKGROUND: Selective inhibition of cyclooxygenase-2 (COX-2) reduces the production of prostaglandin E2 (PGE2), which can have both pro- and anti-inflammatory effects on allergic inflammation. Moreover, in vitro PGE2 has been shown to affect inflammation through the modulation of lymphocyte responses. METHODS: Sixteen subjects with mild allergic asthma were recruited to a two-period cross-over study: one treatment period with the selective COX-2 inhibitor etoricoxib and one without...
