Immunological processes driving IgE sensitisation and disease development in males and femalesIn this review, we discuss recent mechanistic studies casting further light on how the expression of sex hormones may influence the innate and adaptive immune system

Genetic variants of TLR4, including the novel variant, rs5030719, and related genes are associated with susceptibility to clinical malaria in African childrenMalaria is a deadly disease caused by Plasmodium spp. Several blood phenotypes have been associated with malarial resistance, which suggests a genetic component to immune protection.

Personalized transcriptomics reveals heterogeneous immunophenotypes in children with viral bronchiolitisDysregulated expression of IFN-dependent pathways after respiratory viral infections is a defining immunophenotypic feature of AVB-susceptible infants

Nasal delivery of a commensal Pasteurellaceae species inhibits nontypeable Haemophilus influenzae colonisation and delays onset of otitis media in miceWe have demonstrated that a single dose of a closely related commensal can delay onset of NTHi otitis media in vivo
Research
Basophil counts in PBMC populations during childhood acute wheeze/asthma are associated with future exacerbationsOur findings suggest that the proportion of degranulated basophils can also be associated with recurrent exacerbations

Early Life Ovalbumin Sensitization and Aerosol Challenge for the Induction of Allergic Airway Inflammation in a BALB/c Murine ModelThis protocol adapted an experimental animal model of disease for sensitization to ovalbumin during the immediate post-weaning period beginning at 21 days of age

Nasal Delivery of Haemophilus haemolyticus Is Safe, Reduces Influenza Severity, and Prevents Development of Otitis Media in MiceDespite vaccination, influenza and otitis media (OM) remain leading causes of illness. We previously found that the human respiratory commensal Haemophilus haemolyticus prevents bacterial infection in vitro and that the related murine commensal Muribacter muris delays OM development in mice. The observation that M muris pretreatment reduced lung influenza titer and inflammation suggests that these bacteria could be exploited for protection against influenza/OM.

Boosting airway T-regulatory cells by gastrointestinal stimulation as a strategy for asthma controlThe hallmark of atopic asthma is transient airways hyperresponsiveness (AHR) preceded by aeroallergen-induced Th-cell activation.

Single cell transcriptomics reveals cell type specific features of developmentally regulated responses to lipopolysaccharide between birth and 5 yearsHuman perinatal life is characterized by a period of extraordinary change during which newborns encounter abundant environmental stimuli and exposure to potential pathogens. To meet such challenges, the neonatal immune system is equipped with unique functional characteristics that adapt to changing conditions as development progresses across the early years of life, but the molecular characteristics of such adaptations remain poorly understood.

LPS binding protein and activation signatures are upregulated during asthma exacerbations in childrenAsthma exacerbations in children are associated with respiratory viral infection and atopy, resulting in systemic immune activation and infiltration of immune cells into the airways. The gene networks driving the immune activation and subsequent migration of immune cells into the airways remains incompletely understood. Cellular and molecular profiling of PBMC was employed on paired samples obtained from atopic asthmatic children during acute virus-associated exacerbations and later during convalescence.
