IL-4/IL-13 remodeling pathway of COVID-19 lung injury

Regulation of acute lung inflammatory injury by endogenous IL-13.

Using IgG immune complex deposition to trigger acute lung inflammation in rats, we have previously shown that exogenously administered IL-13 suppresses the acute inflammatory response. In the same model, expression of both mRNA and protein for IL-13 has now been detected. Treatment of rats with Ab to IL-13 accentuated the inflammatory response, with significant increases in lung vascular permea...

IL-13 is a therapeutic target in radiation lung injury

Pulmonary fibrosis is a potentially lethal late adverse event of thoracic irradiation. Prior research indicates that unrestrained TGF-β1 and/or type 2 cytokine-driven immune responses promote fibrosis following radiation injury, but the full spectrum of factors governing this pathology remains unclear. Interleukin 13 (IL-13) is a key factor in fibrotic disease associated with helminth infection...

IL-13 induces esophageal remodeling and gene expression by an eosinophil-independent, IL-13R alpha 2-inhibited pathway.

Eosinophilic esophagitis (EE) is an emerging disease associated with both food and respiratory allergy characterized by extensive esophageal tissue remodeling and abnormal esophageal gene expression, including increased IL-13. We investigated the ability of increased airway IL-13 to induce EE-like changes. Mice with pulmonary (but not esophageal) overexpression of IL-13 evidenced esophageal IL-...

IL-13-Induced Inflammation and Remodeling Lung: Role of CCR2 in the Pathogenesis of IL-13-Induced Chemokine Responses in the

IL-13 receptor α2-arginase 2 pathway mediates IL-13-induced pulmonary hypertension.

Although previous literature suggests that interleukin (IL)-13, a T-helper type 2 cell effector cytokine, might be involved in the pathogenesis of pulmonary hypertension (PH), direct proof is lacking. Furthermore, a potential mechanism underlying IL-13-induced PH has never been explored. This study's goal was to investigate the role and mechanism of IL-13 in the pathogenesis of PH. Lung-specifi...
