Purpose: Patients with non-eosinophilic asthma (NEA) are less responsive to anti-inflammatory drugs and suffer from frequent asthma exacerbations. The pathogenic mechanism of NEA is not fully understood; however, the roles of monocytes and autoimmune mechanisms targeting airway epithelial cell (AEC) antigens have been proposed. Methods: The effects of monocyte extracellular traps (MoETs) on cytokeratin 19 (CK19) production in AECs, as well as the impact of CK19-specific immunoglobulin (Ig) G on neutrophil and monocyte activation, were investigated both in vivo and in vitro. Sixty asthmatic patients and 15 healthy controls (HCs) were enrolled, and the levels of serum immune complexes containing CK19-specific IgG and neutrophil extracellular trap (NET)-specific IgG were measured using enzyme-linked immunoassay. Results: MoETs induced CK19 and CK19-specific IgG production. Furthermore, the levels of serum CK19-specific IgG were significantly higher in the NEA group than in the eosinophilic asthma group. Among patients with NEA, asthmatics with high levels of CK19-specific IgG had higher levels of myeloperoxidase and NET-specific IgG than those with low levels of CK19-specific IgG (P = 0.020 and P = 0.017; respectively). Moreover, the immune complexes from asthmatics with high CK19-specific IgG enhanced NET formation and reactive oxygen species production (neutrophil activation), which were suppressed by N-acetylcysteine and anti-CD16 antibody treatment. Conclusions: These findings suggest that circulating CK19 and CK19-specific IgG may contribute to NET formation, leading to airway inflammation and steroid resistance in NEA.
