Fig. 6From: Anti-inflammatory potential of PI3Kδ and JAK inhibitors in asthma patientsExpression of PI3Kδ in bronchial biopsies from asthma patients (n = 13) and healthy subjects (n = 12). PI3Kδ expression was examined in bronchial tissue by immunohistochemistry. Results are presented as positive cells per mm of epithelium (a) and positive cells per mm2 of subepithelium (b). Expression in asthma tissue was compared with healthy by Mann-Whitney tests. *p < 0.05; **p < 0.01; ***p < 0.001. Representative images show PI3Kδ expression in bronchial tissue from healthy subjects (c) and asthma patients (d). Arrows and amplified images highlight positive staining in the subepithelial inflammatory cells. Black bars represent 100 μmBack to article page
