Persistent activation of interlinked type 2 airway epithelial gene networks in sputum-derived cells from aeroallergen-sensitized symptomatic asthmaticsOur findings provide new insight into the molecular mechanisms operative at baseline in the airway mucosa in atopic asthmatic with natural aeroallergen exposure

Environmental Factors in Children's Asthma and Respiratory EffectsChildhood asthma is a condition characterized by airflow obstruction that varies in time spontaneously, in response to various environmental stimuli...

T-cell activation genes differentially expressed at birth in CD4+ T-cells from children who develop IgE food allergyTo show underlying mechanisms, we examined differences in T-cell gene expression in samples at birth and at 1 year in children with and without IgE allergy.

Interaction between adaptive and innate immune pathways in the pathogenesis of atopic asthma: Operation of a lung/bone marrow axisAtopic asthma is the most common form of asthma, particularly during childhood, and in many cases it persists into adult life.

Risk factors for bronchial hyperresponsiveness in teenagers differ with sex and atopic statusSex-related differences in bronchial hyperresponsiveness (BHR) have been reported in adolescents, but the mechanisms remain obscure.

Virus infection and allergy in the development of asthma: What is the connection?Information is accumulating which implicates airway inflammation resulting from respiratory viral infections, acting against a background of atopy.

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.

OPTIMUM study protocol: an adaptive randomised controlled trial of a mixed whole-cell/acellular pertussis vaccine scheduleCombination vaccines containing whole-cell pertussis antigens were phased out from the Australian national immunisation programme between 1997 and 1999 and replaced by the less reactogenic acellular pertussis (aP) antigens. In a large case-control study of Australian children born during the transition period, those with allergist diagnosed IgE-mediated food allergy were less likely to have received whole-cell vaccine in early infancy than matched population controls (OR: 0.77 (95% CI, 0.62 to 0.95)). We hypothesise that a single dose of whole-cell vaccine in early infancy is protective against IgE-mediated food allergy.

Transplacental Innate Immune Training via Maternal Microbial Exposure: Role of XBP1-ERN1 Axis in Dendritic Cell Precursor ProgrammingWe recently reported that offspring of mice treated during pregnancy with the microbial-derived immunomodulator OM-85 manifest striking resistance to allergic airways inflammation, and localized the potential treatment target to fetal conventional dendritic cell (cDC) progenitors. Here, we profile maternal OM-85 treatment-associated transcriptomic signatures in fetal bone marrow, and identify a series of immunometabolic pathways which provide essential metabolites for accelerated myelopoiesis.
