Anti-inflammatory activity of β2-agonists in primary lung epithelial cells is independent of glucocorticoid receptor
In patients with asthma and chronic obstructive pulmonary disease, the addition of long-acting β2-agonists (LABA) to glucocorticosteroids (GCS) results in better control than increasing the dose of GCS alone. In smooth muscle cells and fibroblasts, one apparent underlying mechanism involves the ability of LABAs to activate the glucocorticoid receptor (GR). The present study investigates the effect
