Identification and Isolation of Rodent Respiratory Tract Dendritic Cells

This chapter describes the preparation of respiratory tract tissue from both mice and rats for the isolation of respiratory tract dendritic cells (RTDC).

Toll-like receptor 7 function is reduced in adolescents with asthma

Anti-viral innate immune responses may be impaired in asthma, although the mechanisms are not well understood.

Single cell transcriptomics reveals cell type specific features of developmentally regulated responses to lipopolysaccharide between birth and 5 years

Human 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 children

Asthma 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.

Maternal diet modulates the infant microbiome and intestinal Flt3L necessary for dendritic cell development and immunity to respiratory infection

Poor maternal diet during pregnancy is a risk factor for severe lower respiratory infections in the offspring, but the underlying mechanisms remain elusive. Here, we demonstrate that in mice a maternal low-fiber diet led to enhanced LRI severity in infants because of delayed plasmacytoid dendritic cell recruitment and perturbation of regulatory T cell expansion in the lungs.

Transplacental immune modulation with a bacterial-derived agent protects against allergic airway inflammation

These data provide proof of concept supporting the rationale for developing transplacental immune reprogramming approaches for primary disease prevention

Trajectories of childhood immune development and respiratory health relevant to asthma and allergy

Our findings demonstrate the utility of unsupervised analysis in elucidating heterogeneity in asthma pathogenesis

Genome-wide association and HLA fine-mapping studies identify risk loci and genetic pathways underlying allergic rhinitis

GWAS analyses of allergic sensitization against inhalant allergens and nonallergic rhinitis suggested shared genetic mechanisms across rhinitis-related traits

Persistent activation of interlinked type 2 airway epithelial gene networks in sputum-derived cells from aeroallergen-sensitized symptomatic asthmatics

Our findings provide new insight into the molecular mechanisms operative at baseline in the airway mucosa in atopic asthmatic with natural aeroallergen exposure

Multiancestry association study identifies new asthma risk loci that colocalize with immune-cell enhancer marks

We identified new asthma loci, found new associations at loci implicated in the comorbidity of asthma plus hay fever and confirmed nine known loci.
