Figure 4From: Impact of endobronchial allergen provocation on macrophage phenotype in asthmaticsCharacterization of human alveolar macrophages (AMΦ) after endobronchial allergen provocation in healthy individuals and asthmatics. AMΦ were isolated at baseline (B) and from saline (S), standard allergen (A) and one-tenth of the standard allergen dose (A1/10) challenged segments. A, Protein surface marker expression of AMΦ, mean fluorescence intensities (MFI) after isotype control correction are shown (n = 4 for healthy subjects and n = 6-8 for asthmatics). B, mRNA expression of CCL13, CCL17 and CLEC10A as fold induction compared to individual baseline control (n = 7). C, Correlation between CCL17 and CLEC10A mRNA expression and eosinophilia in BAL of allergen challenged segments (A + A1/10, n = 14). D, Gene expression under baseline conditions (as fold induction compared to mean baseline expression in macrophages of healthy subjects) (n = 7). Data (A, and B) were analyzed with one way ANOVA. *P < .05, ** P < .01 **, and *** P < .001. The Spearman rank correlation test was used in C.Back to article page
