Early aberrant antibody responses, aeroallergen sensitised people, subclinical bacterial infection

Research question: Are asthma and allergies more common in adolescents conceived with assisted reproductive technologies (ART) compared with adolescents conceived without?

Results from recent clinical studies suggest potential efficacy of immune training (IT)-based approaches for protection against severe lower respiratory tract infections in infants, but underlying mechanisms are unclear.

The immunological changes underpinning acquisition of remission (also called sustained unresponsiveness) following food immunotherapy remain poorly defined. Limited access to effective therapies and biosamples from treatment responders has prevented progress. Probiotic peanut oral immunotherapy is highly effective at inducing remission, providing an opportunity to investigate immune changes.

Impaired interferon response and allergic sensitization may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells play a key role in antiviral immunity as critical producers of type I interferons. 

Atopic dermatitis is a common inflammatory skin condition and prior genome-wide association studies have identified 71 associated loci. In the current study we conducted the largest AD GWAS to date combining previously reported cohorts with additional available data.

Rhinoviruses (RVs) can cause severe wheezing illnesses in young children and patients with asthma. Vaccine development has been hampered by the multitude of RV types with little information about cross-neutralization. We previously showed that neutralizing antibody (nAb) responses to RV-C are detected twofold to threefold more often than those to RV-A throughout childhood. Based on those findings, we hypothesized that RV-C infections are more likely to induce either cross-neutralizing or longer-lasting antibody responses compared with RV-A infections.

This article looks at the clinical implications of the research into microbial exposure & protection against asthma.

Asthma is more common in childhood than in adulthood and is more correctly thought of as a syndrome than as a discrete condition.

Food allergy (FA) affects 2%-10% of US children and is a growing clinical and public health problem.
