Decoding Susceptibility to Respiratory Viral Infections and Asthma Inception in ChildrenHuman Respiratory Syncytial Virus and Human Rhinovirus are the most frequent cause of respiratory tract infections in infants and children and are major triggers of acute viral bronchiolitis, wheezing and asthma exacerbations.

The intersect of genetics, environment, and microbiota in asthma-perspectives and challengesIn asthma, a significant portion of the interaction between genetics and environment occurs through microbiota. The proposed mechanisms behind this interaction are complex and at times contradictory. This review covers recent developments in our understanding of this interaction: the "microbial hypothesis" and the "farm effect"; the role of endotoxin and genetic variation in pattern recognition systems; the interaction with allergen exposure; the additional involvement of host gut and airway microbiota; the role of viral respiratory infections in interaction with the 17q21 and CDHR3 genetic loci; and the importance of in utero and early-life timing of exposures.

Azithromycin inhibits mucin secretion, mucous metaplasia, airway inflammation, and airways hyperresponsiveness in mice exposed to house dust mite extractExcessive production, secretion, and retention of abnormal mucus is a pathological feature of many obstructive airways diseases including asthma. Azithromycin is an antibiotic that also possesses immunomodulatory and mucoregulatory activities, which may contribute to the clinical effectiveness of azithromycin in asthma.

Development of a Symptom-Based Tool for Screening of Children at High Risk of Preschool AsthmaDespite advances in asthma therapeutics, the burden remains highest in preschool children; therefore, it is critical to identify primary care tools that distinguish preschool children at high risk for burdensome disease for further evaluation.

Vitamin D receptor polymorphisms are associated with severity of wheezing illnesses and asthma exacerbations in childrenThese findings suggest that genetic variants at the VDR locus may play a role in acute wheeze/asthma severity in children

Progressive increase of FcεRI expression across several PBMC subsets is associated with atopy and atopic asthma within school-aged childrenThe expression pattern of FcεRI on DC and basophils differentiates asthmatic from non-asthmatic atopic children

Chronic cat allergen exposure induces a Th2 cell-dependent IgG4 response related to low sensitizationThis study evaluated the relationship between cat allergen–specific biomarkers in adults with cat allergy with and without cat ownership.

Elucidation of pathways driving asthma pathogenesis: Development of a systems-level analytic strategyWhereas asthma was rare in the late 1800s and early 1900s, the marked increase in its incidence and prevalence since the 1960s points to substantial gene ×...

Maternal diet modulates the infant microbiome and intestinal Flt3L necessary for dendritic cell development and immunity to respiratory infectionPoor maternal diet during pregnancy is a risk factor for severe lower respiratory infections in the offspring, but the underlying mechanisms remain elusive. Here, we demonstrate that in mice a maternal low-fiber diet led to enhanced LRI severity in infants because of delayed plasmacytoid dendritic cell recruitment and perturbation of regulatory T cell expansion in the lungs.
