IL6 and asthma: Elevated levels of IL‐6 and IL‐6TS in asthmatic patients have been associated with more severe disease across multiple patient subsets, and moreover, experimental exposure has shown that IL‐6 and IL‐6TS components are upregulated in the airways, suggesting that stimulus‐induced IL‐6 release may further contribute to airway inflammation and disease severity [27, 28], implicating IL‐6 in the pathogenesis and exacerbations of asthma.
