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

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

Functional differences in airway dendritic cells determine susceptibility to IgE-sensitizationRespiratory IgE-sensitization to innocuous antigens increases the risk for developing diseases such as allergic asthma.

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

Size-Dependent Uptake of Particles by Pulmonary Antigen-Presenting Cell PopulationsThe respiratory tract is an attractive target organ for novel diagnostic and therapeutic applications with nano-sized carriers, but their immune effects and...

Mapping changes in immune cell populations in gestational tissues over the course of pregnancyThis is a strategic “pilot” project in which we are seeking basic information on the immune cell content of gestational tissues.

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.

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.

Impaired interferon response in plasmacytoid dendritic cells from children with persistent wheezeImpaired 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.

Associations between the human immune system and gut microbiome with neurodevelopment in the first 5 years of life: A systematic scoping reviewThe aim of this review was to map the literature assessing associations between maternal or infant immune or gut microbiome biomarkers and child neurodevelopmental outcomes within the first 5 years of life. We conducted a PRISMA-ScR compliant review of peer-reviewed, English-language journal articles.
