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...

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

Role of stem cell precursors in tissuesWe have recently published a paper identifying precursor populations in peripheral lung (2017), and have also discovered that these populations can be found in multiple tissues.

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.

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.

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.

OMIP 076: High-dimensional immunophenotyping of murine T-cell, B-cell, and antibody secreting cell subsetsThere is now considerable evidence demonstrating that both prenatal and postnatal exposure to particular classes of microbial stimuli can provide beneficial signals during early life immune development, resulting in the protection against future inflammatory disease.

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.

Immunoinflammatory responses to febrile lower respiratory infections in infants display uniquely complex/intense transcriptomic profilesthe association between infant LRTI and risk for persistent wheeze/asthma in this cohort is generally stronger for fLRTIs than for other infection categories
