چکیده

An endothelial cell-tropic and leukotropic human cytomegalovirus (HCMV) clinical isolate was cloned as a fusion-inducing factor X-bacterial artificial chromosome in Escherichia coli, and the ribonucleotide reductase homolog UL45 was deleted. Reconstituted virus RVFIX and RV Delta UL45 grew equally well in human fibroblasts and human endothelial cells. Thus, UL45 is dispensable for growth of HCMV in both cell types.

Cooperative inhibition of RIP1-mediated NF-κB signaling by cytomegalovirus-encoded deubiquitinase and inactive homolog of cellular ribonucleotide reductase large subunit

Several viruses have been found to encode a deubiquitinating protease (DUB). These viral DUBs are proposed to play a role in regulating innate immune or inflammatory signaling. In human cytomegalovirus (HCMV), the largest tegument protein encoded by UL48 contains DUB activity, but its cellular targets are not known. Here, we show that UL48 and UL45, an HCMV-encoded inactive homolog of cellular ...

The human cytomegalovirus UL45 gene product is a late, virion-associated protein and influences virus growth at low multiplicities of infection.

Human cytomegalovirus (HCMV) encodes a protein related to the large (R1) subunit of ribonucleotide reductase (RR), but does not encode the corresponding small (R2) subunit. The R1 homologue, UL45, lacks many catalytic residues, and its impact on deoxyribonucleotide (dNTP) production remains unknown. Here, UL45 is shown to accumulate at late stages of infection and to be a virion tegument protei...

Growth and Isolation of Human Cytomegalovirus on a New Human Fetal Foreskin Fibroblast-derived Cell Line in Iran

Cell culture technique has been used for detection and confirmation of many different viruses in clinical samples. Although, new diagnostic methods have been developed for viral infections, traditional cell culturetechnique is still regarded as the “gold standard” for several infectious agents such as human cytomegalovirus(HCMV). In the present study, a new human fetal foreskin fibr...

Development of a Sensitive Quantitative Competitive PCR Assay for Detection of Human Cytomegalovirus DNA

Accurate and rapid diagnosis of human cytomegalovirus (HCMV) disease in immunocompromised patients has remained as a challenge. Quantitative competitive PCR (QC-PCR) methods for detection of HCMV in these individuals have improved the positive and negative predictive values of PCR for diagnosis of HCMV disease. In this study we used QC-PCR assay, using a co-amplified DNA standard, to quantitate...

Objective(s):Human Cytomegalovirus (HCMV) remains a major morbidity and mortality cause in immuno suppressed patients. Therefore, significant effort has been made towards the development of a vaccine. In this study, the expression of the pp65 and gB fusion peptides and Fc domain of mouse IgG2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (APCs) in Pich...
