Suppression of adrenomedullin contributes to vascular leakage and altered epithelial repair during asthmaThe anti-inflammatory peptide, adrenomedullin (AM), and its cognate receptor are expressed in lung tissue, but its pathophysiological significance in airway...

Sensitizing and Th2 Adjuvant Activity of Cysteine Protease AllergensHere, we report on a model that does not use Th2-skewing adjuvants and yet achieves sensitization solely via the nasal mucosa.

ACE2 expression is elevated in airway epithelial cells from older and male healthy individuals but reduced in asthmaCOVID-19 is complicated by acute lung injury, and death in some individuals. It is caused by SARS-CoV-2 that requires the ACE2 receptor and serine proteases to enter AEC. We determined what factors are associated with ACE2 expression particularly in patients with asthma and COPD. We obtained lower AEC from 145 people from two independent cohorts, aged 2-89 years, Newcastle (n = 115) and Perth (n = 30), Australia. The Newcastle cohort was enriched with people with asthma (n = 37) and COPD (n = 38). Gene expression for ACE2 and other genes potentially associated with SARS-CoV-2 cell entry was assessed by qPCR, and protein expression was confirmed with immunohistochemistry on endobronchial biopsies and cultured AEC.

Identification of epithelial phospholipase A2 receptor 1 as a potential target in asthmaPLA2R1 is increased in the airway epithelium in asthma, and serves as a regulator of airway hyperresponsiveness, airway permeability, antigen sensitization, and airway inflammation

In utero cigarette smoke exposure impairs somatic and lung growth in BALB/c miceThe aim of this study was to assess whether in utero tobacco smoke exposure alone affects early-life lung growth and development. Pregnant BALB/c mice...

Impaired interferon response in plasmacytoid dendritic cells from children with persistent wheezeImpaired interferon response and allergic sensitization may contribute to virus-induced wheeze and asthma development in young children. Plasmacytoid dendritic cells play a key role in antiviral immunity as critical producers of type I interferons.
