Small nucleolar RNA networks are up-regulated during human anaphylaxis

Anaphylaxis is a severe, potentially life-threatening allergic reaction driven primarily by the activation of mast cells. We still fail to understand factors underlying reaction severity. Furthermore, there is currently no reliable diagnostic test to confirm anaphylaxis in the emergency department.

Unlocking immune-mediated disease mechanisms with transcriptomics

The transcriptome represents the entire set of RNA transcripts expressed in a cell, reflecting both the underlying genetic and epigenetic landscape and environmental influences, providing a comprehensive view of functional cellular states at any given time. Recent technological advances now enable the study of the transcriptome at the resolution of individual cells, providing exciting opportunities to characterise cellular and molecular events that underpin immune-medicated diseases.

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.

Airway Epithelial Cell Immunity Is Delayed During Rhinovirus Infection in Asthma and COPD

We propose that propensity for viral exacerbations of asthma and COPD relate to delayed expression of epithelial cell innate anti-viral immune genes

Bilateral murine tumor models for characterizing the response to immune checkpoint blockade

This protocol describes bilateral murine tumor models that display a symmetrical yet dichotomous response to immune checkpoint blockade

Network using Michaelis–Menten kinetics: constructing an algorithm to find target genes from expression data

We derived a simple ordinary differential equation-based model using Michaelis–Menten Kinetics to process the microarray data

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

Innate immune activation occurs in acute food protein–induced enterocolitis syndrome reactions

Food reactions in food protein–induced enterocolitis syndrome are predominantly underpinned by activation of the innate immune system

Upper Airway Cell Transcriptomics Identify a Major New Immunological Phenotype with Strong Clinical Correlates in Young Children with Acute Wheezing

Asthma exacerbations in children can be divided into IRF7hi versus IRF7lo phenotypes with associated differences in clinical phenotypes

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
