Environmental Factors in Children's Asthma and Respiratory Effects

Childhood asthma is a condition characterized by airflow obstruction that varies in time spontaneously, in response to various environmental stimuli...

Characterization of “bystander” effects of the diphtheria-pertussis-tetanus (DTP) vaccine on the IgE system

We are seeking more detailed information on how the immune system of infants responds to the vaccine, with the aim of identifying which aspects of the immune r

Research

Genetic polymorphism of KIR2DL4 (CD158d), a putative NK cell receptor for HLA-G, does not influence susceptibility to asthma

No reproducible associations with KIR2DL4 genotype were identified, leading us to conclude that the KIR2DL4 9A/10A polymorphism has no influence...

Risk factors for bronchial hyperresponsiveness in teenagers differ with sex and atopic status

Sex-related differences in bronchial hyperresponsiveness (BHR) have been reported in adolescents, but the mechanisms remain obscure.

Research

Neonatal antigen-presenting cells are functionally more quiescent in children born under traditional compared with modern environmental conditions

One explanation for the high burden of allergic and autoimmune diseases in industrialized countries is inappropriate immune development under modern...

Maternal serum vitamin D levels during pregnancy and offspring neurocognitive development

The objective was to determine the association between maternal serum 25(OH)-vitamin D concentrations and behavioural, emotional and language outcomes...

T-cell activation genes differentially expressed at birth in CD4+ T-cells from children who develop IgE food allergy

To 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.

A novel role for interleukin-1 receptor signaling in the developmental regulation of immune responses to endotoxin

Suggests that IL-1R1 expression provides an additional level of Myd88-dependent signaling during this period of heighted susceptibility to infection.

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 infection

Poor 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.
