Sphingosylphosphorylcholine-induced vasoconstriction of pulmonary artery: activation of non-store-operated Ca2+ entry.
OBJECTIVE Sphingosylphosphorylcholine (SPC) is an important lipid mediator that has been implicated in vascular disease. As it has not been studied in the pulmonary circulation, we examined its mechanisms of action in rat small intrapulmonary arteries (IPA). METHODS IPA were mounted on a myograph for recording tension and intracellular Ca2+ concentration ([Ca2+]i). Ca2+ sensitisation was exam...

AIMS Sphingosylphosphorylcholine (SPC) elicits vasoconstriction at micromolar concentrations. At lower concentrations (≤1 µmol/L), however, it does not constrict intrapulmonary arteries (IPAs), but strongly potentiates vasoreactivity. Our aim was to determine whether this also occurs in a systemic artery and to delineate the signalling pathway. METHODS AND RESULTS Rat mesenteric arteries and ...
متن کاملAssessment of pulmonary vasoreactivity in children with pulmonary hypertension.
PURPOSE OF REVIEW With the current advance in understanding and treatment of pulmonary arterial hypertension in children, pulmonary vasoreactivity testing would navigate the treatment option. An inclusive review of the milestone studies and also recent literature over the last few years on the pulmonary vasoreactivity testing in children will provide the update on various available pulmonary va...
متن کاملTesting pulmonary vasoreactivity* Teste de vasorreatividade pulmonar
Pulmonary arterial hypertension is classified as idiopathic or secondary (associated with collagenoses, heart disease, portal hypertension, pulmonary thromboembolism, and pulmonary vascular diseases). Pulmonary vasoreactivity should be tested in order to define the best treatment option. Of the many drugs that have been used to test pulmonary vasoreactivity, inhaled nitric oxide is the best cho...
