Research progress in regulating cAMP pathway to prevent and treat chronic obstructive pulmonary disease / 中国药理学通报

Cyclic adenosine monophosphate(cAMP)is a “second messenger” that regulates cell signal transduction. Adenylyl cyclases(ACs)and phosphodiesterases(PDEs)can directly regulate cAMP level in cells and then regulate the downstream signaling pathways. Increasing intracellular cAMP level can inhibit inflammation and enhance smooth muscle relaxation, which is an effective strategy for the prevention and treatment of chronic obstructive pulmonary disease(COPD). This paper briefly summarizes the signaling pathways regulating cAMP and their mechanisms and related drugs in COPD therapy, hoping to provide references for further research and development of new target drugs which regulate cAMP for the prevention and treatment of COPD.
