Serotonin-induced smooth muscle hyperplasia in various forms of human pulmonary hypertension.
Hyperplasia of pulmonary artery smooth muscle cells (PA-SMCs) is a hallmark pathological feature of pulmonary hypertension (PH). Serotonin (5-HT) is involved in the hyperplasia through its interactions with specific receptors and internalization by a specific plasma membrane transporter. We investigated the expression and role of the 5-HT transporter (5-HTT) and 5-HT1B, 5-HT2A, and 5-HT2B recep...
متن کاملCross talk between endothelial and smooth muscle cells in pulmonary hypertension: critical role for serotonin-induced smooth muscle hyperplasia.
BACKGROUND The mechanism of pulmonary artery smooth muscle cell (PA-SMC) hyperplasia in idiopathic pulmonary artery hypertension (iPH) may involve both an inherent characteristic of PA-SMCs and abnormal control by external stimuli. We investigated the role of pulmonary microvascular endothelial cells (P-ECs) in controlling PA-SMC growth. METHODS AND RESULTS Serum-free medium of quiescent P-EC...
متن کاملSerotonin transporter overexpression is responsible for pulmonary artery smooth muscle hyperplasia in primary pulmonary hypertension.
Hyperplasia of pulmonary artery smooth muscle cells (PA-SMCs) is a hallmark pathological feature of primary pulmonary hypertension (PPH). Here we found that PA-SMCs from patients with PPH grow faster than PA-SMCs from controls when stimulated by serotonin or serum and that these effects are due to increased expression of the serotonin transporter (5-HTT), which mediates internalization of indol...
متن کاملThe pulmonary capillary bed in various forms of pulmonary hypertension.
IN A PREVIOUS STUDY of the pulmonary capillary bed in mitral valve disease,' the mean value for pulmonary diffusing capacity for carbon monoxide (DL) was found to be significantly lower than normal, in agreement with several other reports.2 7 This was due mainly to impairment of the membrane diffusing capacity (DM). Reduction in pulmonary capillary blood volume (V,) was found only in patients w...
متن کاملFractalkine-induced smooth muscle cell proliferation in pulmonary hypertension.
Pulmonary hypertension is characterised by a progressive increase in pulmonary arterial resistance due to endothelial and smooth muscle cell proliferation resulting in chronic obstruction of small pulmonary arteries. There is evidence that inflammatory mechanisms may contribute to the pathogenesis of human and experimental pulmonary hypertension. The aim of the study was to address the role of ...
