From: Up-regulation of ACE2, the SARS-CoV-2 receptor, in asthmatics on maintenance inhaled corticosteroids
Correlation of absolute eosinophil and serum IgE levels and FEV1 response to bronchodilators with large airway epithelium (LAE) ACE2 expression. A–C Nonsmoker asthmatics not treated with inhaled corticosteroids (ICS, ICS−, n = 38). D–F Nonsmoker asthmatics treated with maintenance ICS (ICS+, n = 19). A, D Eosinophil level vs ACE2 expression. B, E IgE level vs ACE2 expression. C, F FEV1 response to bronchodilators (FEV1 post- vs pre-bronchodilators, presented as % change) vs ACE2 expression
