Problem:Question: Does low-dose theophylline exert its anti-inflammatory effects in mild asthma through upregulation of interleukin-10 in alveolar macrophages?
Answer: LDT has an anti-inflammatory effect in asthma; however, this effect is not mediated via the production of IL-10 or the attenuation of GM-CSF or TNF-alpha. The mechanisms of theophylline activity remain to be determined.

no
