CytoMegaloVirus Infection Database: A Public Omics Database for Systematic and Comparable Information of CMV

AbstractCytoMegaloVirus (CMV) is known to cause infection in humans and may remain dormant throughout the life span of an individual. CMV infection has been reported to be fatal in patients with weak immunity. It is transmitted through blood, saliva, urine, semen and breast milk. Although medications are available to treat the infected patients, there is no cure for CMV. This concern prompted us to construct a comprehensive database having exhaustive information regarding CMV, its infections and therapies to be available on a single platform. Thus, we propose a newly designed database that includes all the information from various public resources such as biological databases, virus taxonomy databanks, viral databases, and drug bank, integrated into this database, named as cytomegalovirus database (CMVdb). It features all the relevant data regarding the strains of CMV, genes, expressed proteins, the genomic sequence of CMV and drugs used in the treatment of cytomegalovirus infection. CMVdb has a unique feature of in-house data analysis, so all the data obtained from various resources are processed within the system. The user interface is more responsive because of the integrated platform that will highly facilitate the researchers. Based on CMVdb functionality and quality of the data, it will accelerate the research and development in the field of infectious diseases and immunology with a special focus on CMV. The obtained data would be useful in designing better therapeutic ...

We describe a simple method for determining systemic GCV concentrations using dried blood spot (DBS) samples. GCV was extracted from a single 6 mm punch via sonication in methanol, then quantified using liquid chromatography-tandem mass spectrometry. The assay was accurate and precise in the dynamic range of 10 to 10,000 ng/mL. GCV concentrations determined in DBS agreed well with GCV concentrations observed in serum. The assay was successfully applied to patient samples, and will be used to support pharmacokinetic studies in an ongoing clinical trial of VGC in infants with CMV-mediated hearing loss.

This article describes the studies that have been conducted to date and emphasises that mortality after stem cell transplant (not attributed to CMV end-organ disease) has recently become the first proven indirect effect of CMV now that letermovir has significantly reduced non-relapse deaths.The implications for CMV vaccines are then discussed. Vaccines are already predicted to be highly cost-effective if they can reduce CMV end-organ disease. Health planners should now consider that cost effectiveness is likely to be enhanced further through reduction of the indirect effects of CMV. A prototype scheme for assessing this po...

In this study, -21 methionine (M)-expressing alleles supplying HLA-E binding peptides were largely poor ligands for inhibitory killer immunoglobulin-like receptors (KIRs), and a bias to NKG2A-mediated education of functionally-potent NK cells was observed. Here, we investigated the effect of this polymorphism on the phenotype and functional capacity of peripheral blood NK cells in a cohort of 36 African individuals with human immunodeficiency virus type 1 (HIV-1)/HCMV co-infection. A similarly profound influence of dimorphism at position -21 of HLA-B on NK cells was not evident in these subjects. They predominantly express...

The unfolded protein response (UPR) is a cellular homeostatic circuit regulating protein synthesis and processing in the ER by three ER-to-nucleus signaling pathways. One pathway is triggered by the inositol-requiring enzyme 1 (IRE1), which splices the X-box binding protein 1 (Xbp1) mRNA, thereby enabling expression of XBP1s. Another UPR pathway activates the activating transcription factor 6 (ATF6). Here we show that murine cytomegalovirus (MCMV), a prototypic β-herpesvirus, harnesses the UPR to regulate its own life cycle. MCMV activates the IRE1-XBP1 pathway early post infection to relieve repression by XBP1u, the ...

Authors: Şahiner F Abstract Human cytomegalovirus (CMV) infections are common in all populations and CMV seroprevalence in women of childbearing age is in the range of 45-100% worldwide. CMV is the most common cause of congenital infections and is associated with fetal development defects and hearing loss. The risk of congenital infection is directly related to maternal immunity and is between 30-40% and 1-2% range in primary and non-primary infections, respectively. Only 5-10% of newborns with congenital infection are symptomatic at birth. Nearly 4% of these babies can die early in life, while 40-60% have to live...

CONCLUSIONS: For brain cancer patients, HCMV-reactivation after the start of radiochemotherapy is a frequent risk for cognitively detrimental but treatable encephalopathy and premature death. Routinely performed HCMV-diagnostics, assessing basophil counts and study-based anti-viral regimens are necessary to combat this hidden threat. PMID: 32060103 [PubMed - as supplied by publisher]
