This study evaluated the detection of Human Cytomegalovirus (HCMV)-DNA in donors' skin samples. HCMV-DNA was quantified in 100 skin specimens, including 50 fresh samples and as many corresponding glycerol-preserved specimens by a home-made Real Time PCR. HCMV-DNA was detected in 19/50 (38%) fresh specimens and 23/50 (46%) glycerol-preserved (p = n.s.). Nevertheless, the mere detection of HCMV-D...

Reactivation of human cytomegalovirus (HCMV) results in severe disease in AIDS patients and immunocompromised patients receiving blood transfusions or organ or bone marrow grafts. Although the site of HCMV latency is unknown, blood cells have been implicated as a viral reservoir. In this study, we demonstrate HCMV reactivation in vitro from seven consecutive healthy donors through allogeneic st...

Genomic variation among human cytomegalovirus (HCMV) strains is probably involved in HCMV-induced pathogenesis. The envelope glycoprotein N (gN) showed extensive genetic polymorphism as HCMV isolates have been clustered into four distinct gN variants (gN-1, gN-2, gN-3, gN-4) whose distribution has been analyzed worldwide using different methodological approaches (PCR-RFLP, PCR-Cloning, PCR-Sequ...

To simplify the detection of infectious human cytomegalovirus (HCMV), we generated a cell line that produced luciferase in a dose-dependent manner upon HCMV infection. Using this cell line, we identified anti-HCMV compounds from a diverse library of 9,600 compounds. One of them, 1-(3,5-dichloro-4-pyridyl)piperidine-4-carboxamide (DPPC), was effective against HCMV (Towne strain) infection of hum...

Human cytomegalovirus (HCMV) is major cause of birth defects upon congenital infection as well as morbidity in immunosuppressed populations and has evolved several mechanisms to evade IFN-I responses. MiR-146a is found to regulate responses IFN-I in a variety of viral infections, but it is not clear whether the same function in HCMV. In this study, we study the effect of miR-146a on HCMV replic...

UNLABELLED Human cytomegalovirus (HCMV) transmission within the host is important for the pathogenesis of HCMV diseases. Natural killer (NK) cells are well known to provide a first line of host defense against virus infections. However, the role of NK cells in the control of HCMV transmission is still unknown. Here, we provide the first experimental evidence that NK cells can efficiently contro...

Human cytomegalovirus (HCMV) infection rewires host cell metabolism, up-regulating flux from glucose into acetyl-CoA to feed fatty acid metabolism, with saturated very long-chain fatty acids (VLFCA) required for production of infectious virion progeny. The human genome encodes seven elongase enzymes (ELOVL) that extend long chain fatty acids into VLCFA. Here we identify ELOVL7 as pivotal for HC...

OBJECTIVE To study the passive immunization with human monoclonal antibodies as for prophylaxis of human cytomegalovirus (HCMV) infection. METHODS Fab monoclonal antibodies to HCMV were recovered by repertoire cloning of mRNA from a HCMV infected individual. Antigen binding specificity, CDR sequence of V(H) and V(L) and neutralizing activity on HCMV AD169 stain were analyzed in vitro. The lig...

UNLABELLED Infection with human cytomegalovirus (HCMV) profoundly affects cellular metabolism. Like in tumor cells, HCMV infection increases glycolysis, and glucose carbon is shifted from the mitochondrial tricarboxylic acid cycle to the biosynthesis of fatty acids. However, unlike in many tumor cells, where aerobic glycolysis is accompanied by suppression of mitochondrial oxidative phosphoryla...

Recent advances in microRNA target identification have greatly increased the number of putative targets of viral microRNAs. However, it is still unclear whether all targets identified are biologically relevant. Here, we use a combined approach of RISC immunoprecipitation and focused siRNA screening to identify targets of HCMV encoded human cytomegalovirus that play an important role in the biol...
