Abstract |
During the last decade, it emerged that cyclic guanosine monophosphate (cGMP) is a novel drug target for the treatment of pulmonary arterial hypertension (PAH). cGMP regulates many cellular functions, ranging from contractility to growth, of relevance to the disease. Generated from guanylyl cyclases in response to natriuretic peptides or nitric oxide (NO), cGMP transduces its effects through a number of cGMP effectors, including cGMP-regulated phosphodiesterases and protein kinases. Furthermore, the cGMP concentration is modulated by cGMP-degrading phosphodiesterases. Data to date demonstrate that increasing intracellular cGMP through stimulation of GCs, inhibition of PDEs, or both is a valid therapeutic strategy in drug development for PAH. New advances in understanding of cGMP are unravelled, as well as the pathobiology of PAH. cGMP remains an attractive future PAH drug target. This review makes a more detailed examination of cGMP signalling with particular reference to PAH.
