Figure 3From: Impaired macrophage phagocytosis of bacteria in severe asthmaRelationship between phagocytosis and lung function parameters. MDM were derived from normal subjects (●, n = 14), non-severe (■, n = 14) and severe asthmatics (▲, n = 14) and exposed to either fluorescently-labeled H. influenzae (Panel A) or S. aureus (Panel B). Alveolar macrophages from normal subjects (●, n = 7) and patients with non-severe asthma (NSA; ■, n = 6) or severe asthma (SA; ▲, n = 8) were exposed to either fluorescently-labeled H. influenzae (Panel C) or S. aureus (Panel D). Correlations were determined using Spearman rank correlation coefficient.Back to article page
