To assess the clinical relevance of a semi-quantitative measurement of human cytomegalovirus (HCMV) DNA in renal transplant recipients within the typical clinical context of a developing country where virtually 100% of both receptors and donors are seropositive for this virus, we have undertaken HCMV DNA quantification using a simple, semi-quantitative, limiting dilution polymerase chain reacti...

Human cytomegalovirus (HCMV) is a major risk factor in transplantation and AIDS patients, which induces high morbidity and mortality. These patients infected with HCMV experience an imbalance of redox homeostasis that cause accumulation of reactive oxygen species (ROS) at the cellular level. H2O2, the most common reactive oxygen species, is the main byproduct of oxidative metabolism. However, t...

Human cytomegalovirus (HCMV) DNA quantitation in whole blood (WB) by real-time or quantitative polymerase chain reaction (qPCR) is a highly sensitive and reproducible diagnostic procedure for monitoring HCMV DNAemia (DNAemia the detection of samples plasma, blood, isolated peripheral leukocytes buffy-coat specimens) patients. We provided comparative analysis extraction performance two different...

Patients diagnosed with high grade serous ovarian adenocarcinoma have a poor prognosis. Recently human cytomegalovirus (HCMV) has been detected in several tumors. Here, we evaluated HCMV in ovarian cancer tissue specimens obtained at pre- and postchemotherapy tumor resection.Available paraffin embedded ovarian cancer tissues from matched pre- and postchemotherapy tumor resection specimens (i.e....

Human cytomegalovirus (HCMV) infections are commonly associated with a generalized immunologic hyporesponsiveness. The present study was designed to evaluate the potential mechanisms of HCMV-associated immunosuppression. In our initial experiments, monocytes in peripheral blood mononuclear cells (PBMCs) exposed to cell-free HCMV appeared morphologically less differentiated than monocytes in PBM...

The human cytomegalovirus (HCMV) protein US6 inhibits the transporter associated with antigen processing (TAP). Since TAP transports antigenic peptides into the endoplasmic reticulum for binding to major histocompatibility class I molecules, inhibition of the transporter by HCMV US6 impairs the presentation of viral antigens to cytotoxic T lymphocytes. HCMV US6 inhibits ATP binding by TAP, henc...

Congenital human cytomegalovirus (HCMV) infection is the major cause of birth defects and a precise definition of the HCMV-specific T-cell response in primary infection may help define reliable correlates of immune protection during pregnancy. In this study, a high throughput method was used to define the frequency of CD4+ and CD8+ T cells specific for four HCMV proteins in the naïve compartmen...

Human cytomegalovirus (HCMV) is a herpesvirus that causes congenital diseases and opportunistic infections in immunocompromised individuals. Its functional proteins and microRNAs (miRNAs) facilitate efficient viral propagation by altering host cell behavior. The identification of functional target genes of miRNAs is an important step in the study of HCMV pathogenesis. HCMV encodes at least 14 m...

Human cytomegalovirus (HCMV) is a ubiquitous human pathogen that infects 40 to 90% of adult human populations. HCMV infections are often asymptomatic in healthy individuals but can cause severe organ and life-threatening disease in immunocompromised patients. The antiviral antibody response to HCMV infection is complex and is known to include virus-neutralizing antibody production against surfa...
