MetabolomicsDelayed gut microbiota maturation in the first year of life is a hallmark of pediatric allergic disease
Allergic diseases affect millions of people worldwide. An increase in their prevalence has been associated with alterations in the gut microbiome, i.e., the microorganisms and their genes within the gastrointestinal tract. Maturation of the infant immune system and gut microbiota occur in parallel; ...

MetabolomicsIntegrated gut metabolome and microbiome fingerprinting reveals that dysbiosis precedes allergic inflammation in IgE‐mediated pediatric cow's milk allergy

BACKGROUND: IgE-mediated cow's milk allergy (IgE-CMA) is one of the first allergies to arise in early childhood and may result from exposure to various milk allergens, of which β-lactoglobulin (BLG) and casein are the most important. Understanding the underlying mechanisms behin...

MetabolomicsLysosomal Acidity and Cathepsin L Activate Eosinophils via ARG1-Mediated Arginine Metabolism in Allergic Airway Inflammation

Eosinophils are the predominant immune cells implicated in the pathogenesis of asthma, highlighting the need for strategies to mitigate their effects. While previous studies have indicated a potential relationship between lysosomes and eosinophils, the precise role of lysosomes in eosinophil acti...

MetabolomicsGinsenoside Rd2 improves allergic asthma by inhibiting PTGS2 enzyme activity
This study aims to elucidate the molecular mechanisms underlying the therapeutic effects of mountain-grown ginseng in allergic asthma and to systematically identify and characterize bioactive monomeric compounds responsible for these effects. We found that total saponins from mountain-grown ginseng ...

TranscriptomicsComparison of two sets of microarray experiments to define allergic asthma expression pattern
Allergic asthma is a complex trait. Several approaches have been used to identify biomarkers involved in this disease. This study aimed at demonstrating the relevance and validity of microarrays in the definition of allergic asthma expression pattern. The authors compared the transcript expressions ...

TranscriptomicsNasal epithelium gene expression profiling in child respiratory allergic disease
Background: In asthma, airway epithelium remodeling can already be detected during childhood, and epithelial cells are more susceptible to virus and oxidative stress. Their exact role in natural history and severity of children allergic respiratory disease remains however surprisingly unexplored. A...

ProteomicsTargeting mitochondrial reactive oxygen species alleviates allergic airway disease in a mouse model of obese allergic asthma
Obesity is associated with severe, difficult to control asthma, and increased airway oxidative stress. Mitochondrial reactive oxygen species (mROS) are an important source of oxidative stress leading us to hypothesize that targeting mROS in obese allergic asthma might be an effective treatment strat...

TranscriptomicsGene expression pattern of alveolar macrophages of allergic asthmatics in comparison with control subjects
The implication of alveolar macrophages (AM) in asthma, a Th2 disease, has not been well characterized. Thus, the goal of this study is to better characterize AM phenotype of allergic asthmatic compared with normal subjects using genomic expression analyses. Microarray analyses were performed with A...

TranscriptomicsEpigenetic changes in B lymphocytes associated with house dust mite allergic asthma.
The increase in atopic diseases has occurred in such a short period of time that it becomes difficult to be attributed only to genetic factors, which usually need more prolonged time periods to manifest. In this setting during the last decade, the science of epigenetics has increasingly developed of...
