(Submitter supplied) The pro-inflammatory cytokine IL-6 is elevated in both blood and airways in asthma. IL-6 signaling is regulated by its receptor composed of two proteins, IL-6R and GP130, that are found in both membrane and soluble forms. The interaction of IL-6 with soluble IL-6R (sIL-6R) can trigger IL-6 trans-signaling in cells such as epithelial cells and fibroblasts, which express GP130, but do not produce sufficient IL-6R. more...

(Submitter supplied) Segmental allergen challenge increases the percentage of eosinophils in bronchoalveolar lavage (BAL) cells. Mepolizumab, an anti-IL-5 therapeutic antibody, decreases the number of eosinophils in bronchoalveolar lavages (BAL). The use of both procedures allows to define genes that are either expressed by eosinophils or dependent on eosinophil presence in the airways.

(Submitter supplied) Background: Although several studies link high levels of IL-6 and soluble IL-6 receptor (sIL-6R) with asthma severity and decreased lung function, the role of IL-6 trans-signaling (IL-6TS) in asthma is unclear. Objective: To explore the association between epithelial IL-6TS pathway activation and molecular and clinical phenotypes in asthma. Methods: Primary human bronchial epithelial cell (HBEC) air-liquid interface (ALI) cultures were stimulated with IL-6 and sIL-6R to establish an IL-6TS gene signature. more...

(Submitter supplied) Asthma influences brain health both functionally (emotions) and structurally (neurodegeneration). Although airway inflammation is proposed to initiate afferent communications with the brain, the associated patterns of airway inflammation and gene-expression profiles are not established. Here, we investigate associations of gene expression in response to allergen challenge in the lung with functional magnetic resonance imaging (fMRI) in the brain.

(Submitter supplied) Protection against endothelial damage is recognized as a frontline approach to preventing the progression of cytokine release syndrome (CRS). Accumulating evidence has demonstrated that interleukin-6 (IL-6) promotes vascular endothelial damage during CRS, although the molecular mechanisms remain to be fully elucidated. Targeting IL-6 receptor signaling delays CRS progression; however, current options are limited by persistent inhibition of the immune system. more...
