In samples co-cultured with fibrocytes from asthmatic patients, we observed a reduction in the production of IL-8 only when dexamethasone was administered at the highest concentration (10–6M, p < 0.05), thereby by indicating less corticosteroid suppression on IL-8 production of co-culture from asthma patients (Figure 3A). The gene discussed is CXCL8; the disease is asthma.
