Low Dose Theophylline Showed an Inhibitory Effect on the Production of IL-6 and IL-8 in Primary Lung Fibroblast from Patients with COPD

Figure 3

Low dose theophylline (5 μg/mL) inhibited the production of interleukin-6/-8 in lung fibroblasts from COPD patients. Data were obtained from 10 independent cell lines. *𝑃<0.05, and **𝑃<0.01, when results between different treatments were compared. IL: interleukin; Theo: theophylline.
