From: BRD4 is involved in viral exacerbation of chronic obstructive pulmonary disease
IL-6 and IL-8 expression is increased in COPD patients with viral exacerbation compared with those in stable condition. The relative mRNA levels (fold change) of IL-6 (A) and IL-8 (B) in the blood of stable COPD patients (sCOPD, n = 25) and COPD patients with viral exacerbation (AECOPD, n = 29) are shown. The relative mRNA levels (fold change) of IL-6 (C) and IL-8 (D) in the sputum of stable COPD patients (sCOPD, n = 25) and COPD patients with viral exacerbation (AECOPD, n = 29) are shown. The protein levels of IL-6 (E) and IL-8 (F) in the plasma of stable COPD patients (sCOPD, n = 25) and COPD patients with viral exacerbation (AECOPD, n = 29) are shown. The protein levels of IL-6 (G) and IL-8 (H) in the sputum of stable COPD patients (sCOPD, n = 25) and COPD patients with viral exacerbation (AECOPD, n = 29) are shown. *P < 0.05, **P < 0.01
