Preexisting Virus-Specific T Lymphocytes-Mediated Enhancement of Adenovirus Infections to Human Blood CD14+ Cells.

Viruses 2019 Feb 13;11(2). Epub 2019 Feb 13.

School of Public Health (Shenzhen), Sun Yat-sen University, Guangdong 518107, China.

Antigen-specific T lymphocytes play a critical role in controlling viral infections. However, we report here that preexisting virus-specific T cell responses also contribute to promoting adenovirus (Ad) infection. Previously, we found that CD14+ monocytes from Ad-seropositive individuals exhibited an increased susceptibility to Ad infection, when compared with that of Ad-seronegative individuals. Read More

Metabolic Reprogramming of the Host Cell by Human Adenovirus Infection.

Viruses 2019 Feb 8;11(2). Epub 2019 Feb 8.

Department of Microbiology and Immunology, Western University, London, ON N6A 3K7, Canada.

Viruses are obligate intracellular parasites that alter many cellular processes to create an environment optimal for viral replication. Reprogramming of cellular metabolism is an important, yet underappreciated feature of many viral infections, as this ensures that the energy and substrates required for viral replication are available in abundance. Human adenovirus (HAdV), which is the focus of this review, is a small DNA tumor virus that reprograms cellular metabolism in a variety of ways. Read More

Novel Adult-Onset Systolic Cardiomyopathy Due to MYH7 E848G Mutation in Patient-Derived Induced Pluripotent Stem Cells.

JACC Basic Transl Sci 2018 Dec 31;3(6):728-740. Epub 2018 Dec 31.

Department of Medicine/Cardiology, University of Washington, Seattle, Washington.

A novel myosin heavy chain 7 mutation (E848G) identified in a familial cardiomyopathy was studied in patient-specific induced pluripotent stem cell-derived cardiomyocytes. The cardiomyopathic human induced pluripotent stem cell-derived cardiomyocytes exhibited reduced contractile function as single cells and engineered heart tissues, and genome-edited isogenic cells confirmed the pathogenic nature of the E848G mutation. Reduced contractility may result from impaired interaction between myosin heavy chain 7 and cardiac myosin binding protein C.

Heinrich Pette Institute, Leibniz Institute for Experimental Virology, Hamburg, Germany.

Cytomegaloviruses (CMVs) have a highly restricted host range as they replicate only in cells of their own or closely related species. To date, the molecular mechanisms underlying the CMV host restriction remain poorly understood. However, it has been shown that mouse cytomegalovirus (MCMV) can be adapted to human cells and that adaptation goes along with adaptive mutations in several viral genes. Read More

Case-control study of the epidemiological and clinical features of human adenovirus 55 and human adenovirus 7 infection in children with acute lower respiratory tract infections in Beijing, China, 2008-2013.

BMC Infect Dis 2018 Dec 7;18(1):634. Epub 2018 Dec 7.

Beijing Key Laboratory of Pediatric Respiratory Infection Diseases, Key Laboratory of Major Diseases in Children, Ministry of Education, National Clinical Research Center for Respiratory Diseases, National Key Discipline of Pediatrics (Capital Medical University), Beijing Pediatric Research Institute, Beijing Children's Hospital, Capital Medical University, National Center for Children's Health, Beijing, China.

Background: In adults, the emerging human adenovirus (HAdV) type 55 (HAdV-55) has been reported to cause more severe cases of adenovirus induced acute lower respiratory tract infections (ALRTIs) compared to other HAdV serotypes (HAdV-3, HAdV-7, HAdV-14). However, there is a dearth of comparative studies in children that address differences in the clinical epidemiological features between HAdV-55 and other HAdV serotypes that can also induce severe infection (such as HAdV-7).

Methods: We conducted a retrospective review of pediatric patients hospitalized at Beijing Children's Hospital with ALRTI from April 2008 to December 2013 who had adenovirus detected from nasopharyngeal or throat samples by PCR. Read More

Seroepidemiological investigation of HAdV-4 infection among healthy adults in China and in Sierra Leone, West Africa.

Emerg Microbes Infect 2018 Dec 5;7(1):200. Epub 2018 Dec 5.

Beijing Institute of Biotechnology, 20 East Street, Beijing, 100071, China.

An apparent increase in the frequency of human adenovirus type 4 (HAdV-4) infections among general populations has been observed over the past 10 years. However, available epidemiological data that may reflect previous viral circulation and assist in predicting potential outbreaks are sparse, particularly in mainland China and Africa. In this study, a convenient neutralization assay for use in the surveillance of historical HAdV-4 infections was established based on a recombinant luciferase-expressing virus. Read More

Cellular Zinc Finger Protein 622 Hinders Human Adenovirus Lytic Growth and Limits Binding of the Viral pVII Protein to Virus DNA.

J Virol 2019 Feb 17;93(3). Epub 2019 Jan 17.

Department of Medical Biochemistry and Microbiology, Uppsala University, Uppsala, Sweden

Human adenovirus (HAdV) encodes a multifunctional DNA-binding protein pVII, which is involved in virus DNA packaging and extracellular immune signaling regulation. Although the pVII is an essential viral protein, its exact role in the virus life cycle and interplay with cellular proteins have remained to a large extent unclear. We have recently identified the cellular zinc finger protein 622 (ZNF622) as a potential pVII-interacting protein. Read More

Metagenomic analysis of viral nucleic acid extraction methods in respiratory clinical samples.

BMC Genomics 2018 Oct 25;19(1):773. Epub 2018 Oct 25.

Key Laboratory for Medical Virology, National Health and Family Planning Commission, National Institute for Viral Disease Control and Prevention, Chinese Center for Disease Control and Prevention, Changping District, Beijing, 102206, China.

Background: Numerous protocols for viral enrichment and genome amplification have been created. However, the direct identification of viral genomes from clinical specimens using next-generation sequencing (NGS) still has its challenges. As a selected viral nucleic acid extraction method may determine the sensitivity and reliability of NGS, it is still valuable to evaluate the extraction efficiency of different extraction kits using clinical specimens directly.

Department of Pediatrics, University of Alabama School of Medicine, Birmingham, AL, 35233, USA. Electronic address:

The search for new compounds with a broad spectrum of antiviral activity is important and requires the evaluation of many compounds against several distinct viruses. Researchers attempting to develop new antiviral therapies for DNA virus infections currently use a variety of cell lines, assay conditions and measurement methods to determine in vitro drug efficacy, making it difficult to compare results from within the same laboratory as well as between laboratories. In this paper, we describe the assessment of antiviral activity of a set of nucleoside analogs against BK polyomavirus, JC polyomavirus, Epstein-Barr virus, human herpesvirus 6B, and human herpesvirus 8 in an automated 384-well format and utilize qPCR assays to measure the accumulation of viral DNA.
