TRPV4 and chronic obstructive pulmonary disease: Accumulating evidence indicates that TRPV4 is involved in a variety of lung diseases, including cough (Bonvini et al., 2016; Bonvini and Belvisi, 2017), asthma (Yao et al., 2019), COPD (Baxter et al., 2014), idiopathic pulmonary fibrosis (Riteau et al., 2010), and acute respiratory distress syndrome (Balakrishna et al., 2014).
