Figure Lengend Snippet: 5-Lipoxygenase (5-LO/ALOX5) mRNA expression is upregulated by IFNγ and downregulated by IL-4 and IL-13 in human monocytes and macrophages from atopic dermatitis (AD) patients. Human monocytes ( A , B ) and macrophages differentiated in the presence of M-CSF ( C , D ) obtained from healthy volunteers (HV) and from AD patients were stimulated with IFNγ, IL-13 or IL-4 for 24 and 48 h or left non-stimulated (NS). 5-LO/ALOX5 mRNA expression was detected by q-PCR and shown as target/reference (Tgt/Ref) ratio. Data are shown as individual values with medians. Significant differences, as determined by Friedman Dunn´s multiple comparison test (black straight bars) or by Kruskal-Wallis test (grey angled bars) are indicated as follows: * p < 0.05; ** p < 0.01; *** p < 0.001; A (n HV = 13, n AD = 15); B (n HV = 8, n AD = 6); C (n HV = 13, n AD = 18); D (n HV = 6, n AD = 6)
Article Snippet: Monocytes and macrophages were stimulated with IL-4 (20 ng/mL), IL-13 (15 ng/mL) or IFNγ (200 ng/mL) (all R&D Systems, Wiesbaden, Germany) for 24 h and 48 h for analyzing the mRNA expression and 24 h for analyzing the protein expression by immunocytochemistry.
