Dual effect of ceramide on human endothelial cells: induction of oxidative stress and transcriptional upregulation of endothelial nitric oxide syntha…

2002

Background— Generation of the second-messenger molecule ceramide by stimulated sphingomyelinase activity has been implicated in the inflammatory processes contributing to the pathogenesis of atherosclerosis. However, reports of stimulatory effects of ceramide on endothelial NO production in animal models suggest antiatherosclerotic effects of the molecule. Therefore, we investigated long-term effects of ceramide on NO generation in human endothelial cells. Methods and Results— In human umbilical vein endothelial cells (HUVECs) and in HUVEC-derived EA.hy 926 endothelial cells, C6-ceramide ( N -hexanoyl- d -erythro-sphingosine) reduced the generation of bioactive NO (RFL-6 reporter-cell assa…

Histamine Upregulates Gene Expression of Endothelial Nitric Oxide Synthase in Human Vascular Endothelial Cells

2003

Background— Histamine has a short-term, transient, stimulating effect on endothelial nitric oxide synthase (eNOS) activity; however, long-term effects on eNOS have not been described yet. In addition, the vascular effect of histamine seems to depend critically on eNOS functionality. Therefore, we studied the effects of histamine on eNOS gene expression and function. Methods and Results— In human umbilical vein endothelial cells (HUVECs) and HUVEC-derived EA.hy 926 cells, histamine upregulated eNOS mRNA (RNase protection assay) and protein (electron microscopic immunocytochemistry) expression. The upregulation of eNOS could be prevented by mepyramine, a selective antagonist at the H 1 recep…

Routine Coronary Angiography is Still the Key Test for Patients Eligible for Lung Transplantation Also for Those With No Symptoms and With High Risk …

2022

Background. Coronary artery disease (CAD) has a considerable morbidity and mortality effect on the outcomes of a lung transplant. Currently, coronary angiography is performed as part of the pretransplant evaluation process. Unfortunately, there are no clear guidelines about performing cardiac angiography in lung transplant candidates. Background. The aim of our work is to find a correlation between cardiovascular risk and coronary arterial status to optimize the selection of patients for coronary angiography prior transplantation. Methods. We retrospectively analyzed 48 patients in whom coronary angiography and cardiac catheterization was performed during assessment for bilateral lung trans…

Estudio de una superfamilia de genes de respuesta a patógenos (repat) en insectos

2012

El intestino de los insectos es una de las principales vías de entrada de entomopatógenos. Con el fin de minimizar los efectos negativos de los patógenos, el intestino de los insectos posee diferentes mecanismos: síntesis de péptidos antimicrobianos, producción de especies reactivas de oxígeno, activación de los sistemas de reparación y detoxificación, melanización, fagocitosis, apoptosis y la renovación celular, entre otros. Estudios de expresión tras la exposición a diferentes patógenos han mostrado cómo la expresión de ciertos genes varía en el intestino tras la infección. Previamente a la realización de esta tesis, se identificó, en el lepidóptero Spodoptera exigua, una familia de genes…
