Asthma is a chronic inflammatory pulmonary disease and respiratory syncytial virus (RSV) infection is a common cause of lower respiratory tract illness in infants and young children. α-Asarone presents many pharmacological effects and has been demonstrated to be useful in treating asthma. However, the functional mechanism of α-asarone in RSV-infected asthma has not been investigated. Long non-coding RNAs (lncRNAs) have been reported to play critical roles in many biological processes. Although many lncRNAs have been characterized, few were reported in asthma, especially in RSV-induced asthma...

INTRODUCTION: Blomia tropicalis is a mite that belongs to the superfamily of Glycyphagidae. Initially described as a storage mite, it is now considered as a house dust mite of tropical and sub-tropical areas. STATE OF THE ART: Sensitization to this mite is very common in South America and Southeast Asia. Epidemiological studies have also found sensitization to this mite in Africa and Central America. Blo t 5 is the major allergen of B. tropicalis. Co-sensitization to other house dust mites such as Dermatophagoides pteronyssinus (Der p) and Dermatophagoides farinae (Der f) is very common...

The recent advances in the knowledge of immunological aspects of many pulmonary diseases, allowed to identify cells, biological functions, cytokines, and receptors that are preferentially involved in each disease. This is the case of asthma, where IL-13 (together with IL-4) is recognized as a central mediator. The role of IL-13 is strictly related, via complex signaling pathways, to eosinophil recruitment and activation, to mucus secretion, periostin generation and to fibrogenic processes (which are part of the remodeling process)...

Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disease with various underlying pathophysiologic mechanisms which translate to endotypes, in contrast to clinical phenotypes or histological subtypes. Defining endotypes can help clinicians predict disease prognosis, select subjects suitable for a specific therapy, and assess risks for comorbid conditions, including asthma. Therefore, with recent advancement of biologicals in CRS clinical trials, endotyping can be a breakthrough in treating recalcitrant CRS...

BACKGROUND: Th2 cytokines like interleukin-4, -5, and -13 are regarded as important drivers of the immunopathology underlying allergic rhinitis (AR) and asthma. The present study explores the capacity of pentosan polysulfate sodium (PPS), a semi-synthetic heparin-like macromolecular carbohydrate, to bind Th2 cytokines and exert biological neutralization in vitro, as well as anti-inflammatory actions in vivo. METHODOLOGY: The capacity of PPS to bind recombinant Th2 cytokines was tested with surface plasmon resonance (SPR) technology and biological Th2 neutralization was assessed by Th2-dependent proliferation assays...

Iron is essential for many biological processes, however, too much or too little iron can result in a wide variety of pathological consequences, depending on the organ system, tissue or cell type affected. In order to reduce pathogenesis, iron levels are tightly controlled in throughout the body by regulatory systems that control iron absorption, systemic transport and cellular uptake and storage. Altered iron levels and/or dysregulated homeostasis have been associated with several lung diseases, including chronic obstructive pulmonary disease, lung cancer, cystic fibrosis, idiopathic pulmonary fibrosis and asthma...

Basophils (BAs) play an important role in the promotion of aberrant Th2 immune response in asthma. It is not only the effective cell, but also modulates initiation of Th2 immune responses. We earlier demonstrated that Notch signaling regulates the biological function of BAs in vitro. However, whether this pathway plays the same role in vivo is not clear. The purpose of the present study was to investigate the effect of Notch signaling on BA's function in the regulation of allergic airway inflammation in a murine model of asthma...

Asthma is a heterogeneous chronic inflammatory disease in which different endotypes contribute to define clinical-inflammatory phenotypes. MicroRNAs (miRNAs) are a class of small, endogenous 22-25 nt RNA molecules that bind to specific mRNAs to inhibit translation and promote mRNA degradation. miRNAs function in post-transcriptional regulation and control physiological and pathological processes in various diseases. The purpose of this review is to summarize and discuss the current knowledge on the function of miRNAs in asthma, focusing the attention particularly on their biological properties, pathophysiologic roles, and potential use as biomarkers and/or therapies for asthma...

Hydrogen sulfide (H2S) is a biologically relevant signaling molecule in mammals. Together with the volatile substances nitric oxide (NO) and carbon monoxide (CO), H2S is defined as a gasotransmitter, playing a physiological role in a variety of functions such as synaptic transmission, vascular tone, angiogenesis, inflammation and cellular signaling. The generation of H2S is catalyzed by cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3 mercaptopyruvate sulfurtransferase (3-MST). The expression of CBS and CSE is tissue-specific with CBS being expressed predominantly in the brain and CSE in peripheral tissues, including lungs...

In children there is limited understanding about the biological and environmental risk factors of fractures. Therefore, we aimed to study the effect of maternal smoking on preschool children's fractures hypothesizing that the fracture risk might be programmed during intrauterine growth in means of disturbed bone formation. A prospective birth cohort included women living in Northern Finland with an expected date of delivery between July 1st, 1985 and June 30th, 1986 (N=9362), and their offspring (N=9432). Smoking was inquired during pregnancy and when the offspring reached seven years of age...

Gender has been shown to impact the prevalence of several lung diseases such as cancer, asthma, chronic obstructive pulmonary disease, and pulmonary arterial hypertension (PAH). Controversy over the protective effects of estrogen on the cardiopulmonary system should be of no surprise as clinical trials of hormone replacement therapy have failed to show benefits observed in experimental models. Potential confounders to explain these inconsistent estrogenic effects include the dose, cellular context, and systemic versus local tissue levels of estrogen...

BACKGROUND: Simple parapneumonic effusion is a pleural effusion associated with lung infection (i.e., pneumonia). Streptococcus pneumoniae remains the most common pathogen causing parapneumonic effusions. In Morocco, the pneumococcal conjugate vaccine 13-valent (PCV13) was introduced in the national immunization program in October 2010 in 2 + 1 schedule for prevention of pneumococcal disease, and replaced by the PCV10 in July 2012 in the same schedule. We report a case of parapneumonic pleural effusions caused by S...

Obstructive respiratory diseases like asthma and chronic obstructive pulmonary disease (COPD) are currently treated by inhaled anti-inflammatory and bronchodilator drugs. Despite the availability of multiple treatments, both diseases are growing public health concerns. The majority of asthma patients are well controlled on current inhaled therapies but a substantial number of patients with severe asthma are not. Asthma affects an estimated 300 million people worldwide and approximately 20 percent have a severe form of the disease...

Particulate matter with aerodynamic diameter ≤2.5 μm (PM2.5 ) is generally composed of carbon nuclei associated with various organic carbons, metals, ions and biological materials. Among these components, polyaromatic hydrocarbons (PAHs) such as benzo(a)pyrene (BaP) and quinones have detrimental effects on airway epithelial cells and immunodisrupting effects, which leads to the exacerbation of respiratory allergies. The effects of PAHs and the carbon nuclei, separately as well as in combination, remain to be established...

Advances in our ability to identify lymphatic endothelial cells and differentiate them from blood endothelial cells have led to important progress in the study of lymphatic biology. Over the past decade, pre-clinical and clinical studies have shown that there are changes to the lymphatic vasculature in nearly all lung diseases. Efforts to understand the contribution of lymphatics and their growth factors to disease initiation, progression and resolution have led to seminal findings establishing critical roles for lymphatics in lung biology spanning from the first breath after birth to asthma, tuberculosis, and lung transplantation...

Asthma encompasses a variety of clinical phenotypes that involve distinct T cell-driven inflammatory processes. Improved understanding of human T-cell biology and the influence of innate cytokines on T-cell responses at the epithelial barrier has led to new asthma paradigms. This review captures recent knowledge on pathogenic CD4(+) T cells in asthmatic patients by drawing on observations in mouse models and human disease. In patients with allergic asthma, TH2 cells promote IgE-mediated sensitization, airway hyperreactivity, and eosinophilia...
