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...

Human cytomegalovirus (HCMV) gB is known to play important roles in cell surface attachment, virion penetration, spread of infection from cell to cell, and provocation of neutralizing antibody. This study was performed to determine the role of anti-HCMV gB antibody in overall neutralizing response in patients with HCMV infection and healthy control with past infection. HCMV gB was stably expres...

Human cytomegalovirus (hCMV) is a prevalent virus that affects large proportion of the population worldwide. Natural Killer (NK) cells are essential immune play crucial role in controlling hCMV infection. Despite wide spread infection, there still not enough data related to association between innate and adaptive immunity. This study investigated coordination some NK cell markers expression hum...

Human cytomegalovirus (HCMV) is a frequent cause of major disease following primary infection or reactivation from latency in immunocompromised patients. It has also been suggested that there may be a link between HCMV and vascular disease. Both smooth muscle and endothelial cells are targets for primary infection with HCMV and have also been postulated as potential sites of HCMV latency. One o...

Human CMV (HCMV) is an important pathogen that causes widespread diseases in immunocompromised individuals. Among the opportunistic HCMV infections, HCMV retinitis is most common in transplant recipients and AIDS patients. It often leads to blindness if left untreated. The question as to how HCMV infection causes retinal pathogenesis remains unresolved. Here, we report that viral immediate-earl...

Human cytomegalovirus (HCMV) is a major cause of viral disease in the young and the immune-suppressed. At sites of infection, HCMV recruits the neutrophil, a cell with a key role in orchestrating the initial immune response. Herein, we report a profound survival response in human neutrophils exposed to the clinical HCMV isolate Merlin, but not evident with the attenuated strain AD169, through s...

Human cytomegalovirus (HCMV) can infect both HCMV-naive and -experienced transplant patients. In this study, the growth rate of HCMV in HCMV-naive hosts (1.82 units/day; 95% confidence interval [CI], 1.44-2.56 units/day) was shown to be significantly faster than the growth rate of virus in HCMV-experienced hosts undergoing recurrent infection (0.61 units/day; 95% CI, 0.55-0.7 units/day; P<.0001...

BACKGROUND We have previously shown that curcumin exhibited an outstanding anti-HCMV effect in vitro and in vivo. However, the underlying mechanism for the anti-HCMV effect remains unclear. METHODS Levels of IL-6 and TNF-α cytokine secretions in HELF cells were determined by enzyme-linked immunosorbent assay (ELISA); cell cycles were assessed by flow cytometry; ie and ul83 gene expressions we...

Glioblastoma multiforme (GBM) is the most common brain tumor in adults. Human cytomegalovirus (HCMV) genomes are present in GBM tumors, yielding hope that antiviral treatments could prove therapeutic and improve the poor prognosis of GBM patients. We discovered that GBM cells infected in vitro with HCMV display properties of cancer stem cells. HCMV-infected GBM cells grow more slowly than mock-...

Viruses depend on the host cell to provide the energy and biomolecular subunits necessary for production of viral progeny. We have previously reported that human cytomegalovirus (HCMV) infection induces dramatic changes to central carbon metabolism, including glycolysis, the tricarboxylic acid (TCA) cycle, fatty acid biosynthesis, and nucleotide biosynthesis. Here, we explore the mechanisms inv...
