Abstract Background Group 2 innate lymphoid cells (ILC2s) play important roles in allergic inflammation. However, their roles in the pathophysiology of allergic rhinitis (AR) are poorly understood. Objective Prevalence of ILC2s in the inferior nasal turbinate (INT) tissues and the activating mechanisms of ILC2s were examined in patients with house dust mites (HDM)‐induced AR. Methods 18 patients with HDM‐induced AR and 13 control subjects were recruited. Fresh INT tissues and peripheral...
Abstract The identification of sputum eosinophilia indicating corticosteroid responsiveness in subjects with severe asthma heralded the beginning of phenotyping asthmatic subjects based on airways inflammation. Since then, the heterogeneity of severe asthma has been explored and the importance of immunobiology has come sharply into focus with the identification of the key Type 2 cytokine pathways driving eosinophilic inflammation. The development of molecules targeting these Type 2 pathways has...
Abstract Background Germline‐encoded innate immune pattern recognition receptors (PRR) are expressed at epithelial surfaces and modulate epithelial defenses. Evidence suggests that stimulation of the Toll‐like receptor (TLR) family of PRR may regulate epithelial barrier integrity by upregulating tight junction (TJ) complex protein expression, but it is not known if this mechanism is utilized in esophageal epithelial cells. TJ complex proteins maintain intact barrier function, and are dysregulated...

Abstract Background A close asssociation between obesity and asthma has been described. The nature of this association remains elusive, especially with respect to allergic asthma. Controversial findings exist regarding the impact short‐term high fat diet (HFD) feeding on the development of allergic asthma. Objective To delineate the impact of short‐term HFD feeding on the development of experimental allergic asthma. Methods Female C57BL/6JRJ mice were fed with a short‐term HFD or...
