The ABp values of these mice at week 10 were not included in the mean value of ABp measurement from each of the four experimental groups that consisted of 12 mice in each group.(0.03 MB DOC) ppat.1000427.s006.doc (32K) GUID:?95964CD1-931E-4869-8EC8-9C4E915EEAB7 Abstract Cytomegalovirus (CMV) infection is a common infection in adults (seropositive 60C99% globally), and is associated with cardiovascular diseases, in line with risk factors such as hypertension and atherosclerosis. RT-PCR primers, Forward: gene. (A) Detection of gene expression in venous EC (CRL-1730) infected by BI-4, BI-5 and AD169. (B) Detection of gene expression in arterial EC (CRL-2472) infected with BI-4, BI-5 and AD169. The EC were infected by clinical isolates BI-4, BI-5 and lab strain AD-169 at an MOI Mouse monoclonal to BNP of 10, respectively. The supernatants of viral infected cultures were harvested at each time point, and HCMV DNA copy numbers were determined by the quantitative HCMV DNA-PCR assays (COBAS). Results shown were from a representative experiment of three performed, and data show that HCMV clinical isolates cIAP1 Ligand-Linker Conjugates 2 persistently infected EC, in contrast to the lab strain AD169.(0.54 MB TIF) ppat.1000427.s005.tif (526K) GUID:?6A091665-6AE5-4425-9B3F-97065C8ACFD0 Table S1: Blood pressures of C57BL/6J mice at week 4 and 10 of experiment (*base line). *The base line of blood pressure was measured in the right carotid of each mouse at week 4 before the MCMV infection, and mice were randomly selected from each group. These mice were treated the same as the other mice in the rest of experiment. At cIAP1 Ligand-Linker Conjugates 2 week 10 of the experiment, the blood pressures of these mice were measured again at the left carotids. The ABp values of these mice at week 10 were not included in the mean value of ABp measurement from each of the four experimental groups that consisted of 12 mice in each group.(0.03 MB DOC) ppat.1000427.s006.doc (32K) GUID:?95964CD1-931E-4869-8EC8-9C4E915EEAB7 Abstract Cytomegalovirus (CMV) infection is a common infection in adults (seropositive 60C99% globally), and is associated with cardiovascular diseases, in line with risk factors such as hypertension and atherosclerosis. Several viral infections are linked to hypertension, including human herpes virus 8 (HHV-8) and HIV-1. The mechanisms of how viral infection contributes to hypertension or increased blood pressure are not defined. In this report, the role of CMV infection as a cause of increased blood pressure and in forming aortic atherosclerotic plaques is examined. Using mouse model and molecular biology analyses, we find that CMV infection alone caused a significant increase in arterial blood pressure (ABp) (and experimental systems and defined that MCMV infection alone results in a significant increase of blood cIAP1 Ligand-Linker Conjugates 2 pressure. Molecular biology analyses show that MCMV infection stimulated pro-inflammatory cytokine expression, which have previously been shown to play a role in an increase of blood pressure [21]C[23]. Specifically, we have identified that CMV infection induced expression of renin in an infection dose responsive manner in mouse renal cells and in human vascular endothelial cells. Additionally, an increased angiotensin II (Ang II) level was detected in mouse serum and in arterial blood vascular tissues after MCMV infection. This is of great interest, since renin is known as a rate limiting protein of Renin-Ang-II system (RAS) and Ang II is the effector peptide that directly binds to blood vessels, causes vasoconstriction and leads to systemic hypertension in humans [24]C[27]. Our studies have defined that CMV infection alone leads to an increase in blood pressure, whereas CMV acts as a co-factor, along with high cholesterol diet to induce atherosclerosis in the mouse aorta. A persistent CMV infection of EC and an increased pro-inflammatory cytokine expression, including renin.
