Transplacental Innate Immune Training via Maternal Microbial Exposure: Role of XBP1-ERN1 Axis in Dendritic Cell Precursor Programming

We 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.

Oestrogen amplifies pre-existing atopy-associated Th2 bias in an experimental asthma model

The role of oestrogen in experimental atopic asthma, and guide future research on sex-related variations in atopic asthma susceptibility/intensity

A method for the generation of large numbers of dendritic cells from CD34+ hematopoietic stem cells from cord blood

Neonatal dendritic cells generated form CD34+ cord blood progenitors have a higher inflammatory potential when exposed to viral than bacterial related stimuli

Tumor necrosis factor α induces α1B-adrenergic receptor expression in keratinocytes

Our results suggest that inflammatory cytokines released during injury stimulate α1-AR expression in keratinocytes

Immunoinflammatory responses to febrile lower respiratory infections in infants display uniquely complex/intense transcriptomic profiles

the association between infant LRTI and risk for persistent wheeze/asthma in this cohort is generally stronger for fLRTIs than for other infection categories

Quantification of Serum Ovalbumin-specific Immunoglobulin E Titre via in vivo Passive Cutaneous Anaphylaxis Assay

We describe herein a highly reproducible in vivo passive cutaneous anaphylaxis assay using Sprague Dawley rats for the quantification of ovalbumin-specific IgE

Pregnancy and Early Life Immunology

The Pregnancy and Early Life Immunology team's overall research vision is targeted towards understanding immunological development during early life.

Epigenetic changes underpinning allergen sensitization: a twin-based study

We are studying immune cells from identical twins of which one suffers and one does not suffer from allergic disease to identify specific mechanisms that may play important roles in disease development.

Finding the cellular explanation for recurrent asthma exacerbations

This study is designed to identify the specific unique immune cell response that occurs in these children with recurrent disease.
