Interleukin-13: Central mediator of allergic asthma

TLDR
In this article, the type 2 cytokine IL-13, which shares a receptor component and signaling pathways with IL-4, was found to be necessary and sufficient for the expression of allergic asthma.
Abstract
The worldwide incidence, morbidity, and mortality of allergic asthma are increasing. The pathophysiological features of allergic asthma are thought to result from the aberrant expansion of CD4 + T cells producing the type 2 cytokines interleukin-4 (IL-4) and IL-5, although a necessary role for these cytokines in allergic asthma has not been demonstrable. The type 2 cytokine IL-13, which shares a receptor component and signaling pathways with IL-4, was found to be necessary and sufficient for the expression of allergic asthma. IL-13 induces the pathophysiological features of asthma in a manner that is independent of immunoglobulin E and eosinophils. Thus, IL-13 is critical to allergen-induced asthma but operates through mechanisms other than those that are classically implicated in allergic responses.

Structural Basis of Signaling Blockade by Anti-IL-13 Antibody Lebrikizumab.

TL;DR: The molecular structure of IL-13 in complex with the Fab from lebrikizumab is reported by X-ray crystallography at 1.9Å resolution and it is shown that lebrikszumab inhibits IL- 13 signaling by binding to IL-14 with very high affinity and blocking IL-3Rα binding toIL-4Rα.

IL-13Rα2 and IL-10 coordinately suppress airway inflammation, airway-hyperreactivity, and fibrosis in mice

TL;DR: It is demonstrated that increased IL-13 receptor alpha 2 (IL-13Ralpha2) expression is responsible for the reduced AHR, mucus production, and fibrosis in BALB/c IL-10(-/-) mice.

Interleukin (IL)-4 and IL-13 up-regulate monocyte chemoattractant protein-1 expression in human bronchial epithelial cells: involvement of p38 mitogen-activated protein kinase, extracellular signal-regulated kinase 1/2 and Janus kinase-2 but not c-Jun NH2-terminal kinase 1/2 signalling pathways.

TL;DR: IL‐4 and IL‐13 were found to up‐regulate gene expression and significantly increase the release of MCP‐1 from BEAS‐2B cells, illustrating that the activation of p38 MAPK, ERK and JAK‐2 but not JNK is crucial for IL‐4‐ andIL‐13‐induced MCP•1 release in human bronchial epithelial cells.

Neonatal Chlamydial Infection Induces Mixed T-Cell Responses That Drive Allergic Airway Disease

TL;DR: Early-life chlamydial infection induces a mixed type 1 and 2 T-cell response to antigen, which differentially affects the development of key features of AAD in the adult.

TL;DR: The existence of subsets of CD4+ helper T lymphocytes that differ in their cytokine secretion patterns and effector functions provides a framework for understanding the heterogeneity of normal and pathological immune responses.

Predominant TH2-like bronchoalveolar T-lymphocyte population in atopic asthma

TL;DR: Atopic asthma is associated with activation in the bronchi of the interleukin-3, 4, and 5 and GM-CSF gene cluster, a pattern compatible with predominant activation of the TH2-like T-cell population.

Eosinophilic inflammation in asthma.

TL;DR: Eosinophilic inflammation of the airways is correlated with the severity of asthma and these cells are likely to play a part in the epithelial damage seen in this disease.

Requirement for IL-13 Independently of IL-4 in Experimental Asthma

TL;DR: This article showed that IL-4 receptor α chain-dependent pathway may underlie the genetic associations of asthma with both the human 5q31 locus and the IL4 receptor and showed that selective neutralization of IL-13, a cytokine related to interleukin-4 that also binds to the α chain of the IL 4 receptor, ameliorated asthma phenotype.

Cellular events in the bronchi in mild asthma and after bronchial provocation.

TL;DR: It is concluded that allergic asthma is accompanied by extensive inflammatory changes in the airways, even in mild clinical and subclinical disease.
