Figure 2. GSTM1 null participants experienced greater WSP-induced airway neutrophil influx.

Figure 2.

GSTM1 null (A) and sufficient (B) participants experienced a significant increase in sputum neutrophil content at 24 hours post-WSP exposure. GSTM1 null participants showed a more robust neutrophilic response than sufficient individuals (C), and this relationship was greatest in responders (D). Wilcoxon-signed rank tests were used to compare 24h post-WSP sputum to baseline sputum (data represented as mean ± SEM; p values derived from log transformed data).
