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

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

Reduced Type-I Interferon by Plasmacytoid Dendritic Cells and Asthma in School-Aged ChildrenAllergic sensitization and reduced ability to respond to viral infections may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells (pDC) are rare immune cells that produce type I interferons (IFN-I) and play a key role in orchestrating immune responses against viruses.

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.

Allergen Specific IgE is a Stronger Predictor of Remission Following Peanut Oral Immunotherapy Than Age in Children Aged 1–10 YearsRemission is the desired outcome following OIT as it allows individuals to discontinue treatment and eat the allergen freely. Early initiation of OIT in infants and toddlers has been embraced as an approach to increase the likelihood of remission. However, there is no high-quality evidence supporting younger age as an independent factor driving remission; available studies are limited by small samples of younger subjects and lack of adjustment for confounding covariates, particularly peanut-specific IgE (sIgE) levels which is closely cor

Sex-Specific Environmental Impacts on Initiation and Progression of Multiple SclerosisThe immunological mechanisms that contribute to multiple sclerosis (MS) differ between males and females. Females are 2-3 times more likely to develop MS compared to males, however the reason for this discrepancy is unknown. Once MS is established, there is a more inflammatory yet milder form of disease in females whereas males generally suffer from more severe disease and faster progression, neural degradation, and disability.

Metabolic dysfunction induced by a high-fat diet modulates hematopoietic stem and myeloid progenitor cells in brown adipose tissue of miceBrown adipose tissue (BAT) may be an important metabolic regulator of whole-body glucose. While important roles have been ascribed to macrophages in regulating metabolic functions in BAT, little is known of the roles of other immune cells subsets, particularly dendritic cells (DCs). Eating a high-fat diet may compromise the development of hematopoietic stem and progenitor cells (HSPCs)-which give rise to DCs-in bone marrow, with less known of its effects in BAT. We have previously demonstrated that ongoing exposure to low-dose ultraviolet radiation (UVR) significantly reduced the 'whitening' effect of eating a high-fat diet upon interscapular (i) BAT of mice.
