CD8+ T cells induced by adenovirus-vectored vaccine are capable of preventing establishment of latent murine γ-herpesvirus 68 infection.

Vaccine 2019 Apr 18. Epub 2019 Apr 18.

Centre for Medical Parasitology, Department of Immunology and Microbiology, University of Copenhagen, Denmark; InProTher ApS, DK2200 Copenhagen, Denmark.

CD8+ T cells are known to control infections, but their role in preventing latent infection from establishing has not been thoroughly investigated. We hypothesized that a potent CD8+ T cell response patrolling the mucosal viral entry points could kill the first infected cells and thereby abrogate the infection before latency is established. To investigate this, replication deficient adenovirus serotype 5 vectors encoding murine γ-herpesvirus-68 CD8+ T cell epitopes linkedto the T cell adjuvant Invariant chain, were developed. Read More

Rapid generation of multivirus-specific T lymphocytes for the prevention and treatment of respiratory viral infections.

Haematologica 2019 Apr 19. Epub 2019 Apr 19.

Center for Cell and Gene Therapy, Baylor College of Medicine, Houston, TX, USA

Respiratory tract infections due to community-acquired respiratory viruses including respiratory syncytial virus, Influenza, parainfluenza virus 3 and human metapneumovirus are detected in up to 40% of allogeneic hematopoietic stem cell transplant recipients in whom they cause severe symptoms including pneumonia and bronchiolitis and can be fatal. Given the lack of effective antivirals and the data from our group demonstrating that adoptively transferred ex vivo-expanded virus-specific T cells can be clinically beneficial for the treatment of both latent (Epstein-Barr virus, cytomegalovirus, BK virus, human herpesvirus 6) and lytic (adenovirus) viruses, we investigated the potential for extending this immunotherapeutic approach to respiratory viruses. We now describe a system that rapidly generates a single preparation of polyclonal (CD4+ and CD8+) virus-specific T cells reactive against 12 antigens derived from 4 viruses (respiratory syncytial virus, Influenza, parainfluenza virus 3 and human metapneumovirus) that commonly cause post-transplant morbidity and mortality.

Histone deacetylase inhibitor SAHA suppresses human adenovirus gene expression and replication.

J Virol 2019 Apr 3. Epub 2019 Apr 3.

Regenerative Medicine Program, Ottawa Hospital Research Institute, Ottawa, Ontario, Canada

Human adenovirus (HAdV) causes minor illnesses in most patients, but can lead to severe disease and death in pediatric, geriatric and immunocompromised individuals. No approved antiviral therapy currently exists for the treatment of these severe HAdV-induced diseases. In this study, we show that the pan-histone deacetylase (HDAC) inhibitor SAHA reduces HAdV-5 gene expression and DNA replication in tissue culture, ultimately decreasing virus yield from infected cells.

Probable Donor-Derived Human Adenovirus Type 34 Infection in 2 Kidney Transplant Recipients From the Same Donor.

Open Forum Infect Dis 2019 Mar 26;6(3):ofy354. Epub 2018 Dec 26.

University of Rochester Medical Center, Rochester, New York.

Human adenovirus type 34 (HAdV-34) infection is a recognized cause of transplant-associated hemorrhagic cystitis and, in rare cases, tubulointerstitial nephritis. The source of such infections is often difficult to assess, that is, whether acquired as a primary infection, exposure to a pathogen in the transplanted organ, or reactivation of an endogenous latent infection. We present here 2 cases of likely transplant-acquired HAdV-34 infection from the same organ donor, manifesting as tubulointerstitial nephritis in 1. Read More

Human Adenovirus type 5 increases host cell fucosylation and modifies Ley antigen expression.

Glycobiology 2019 Mar 14. Epub 2019 Mar 14.

Laboratorio de Glicobiología Humana y Diagnóstico Molecular; Centro de Investigación en Dinámica Celular, Instituto de Investigación en Ciencias Básicas y Aplicadas, Universidad Autónoma del Estado de Morelos. Av. Universidad 1001, Cuernavaca, México.

Certain viral infections are known to modify the glycosylation profile of infected cells through the overexpression of specific host cell fucosyltransferases (FUTs). Infection with CMV (cytomegalovirus), HCV (hepatitis C virus), HSV-1 (herpes simplex virus type-1) and VZV (varicella-zoster virus) increase the expression of fucosylated epitopes, including antigens sLex (Siaα2-3 Galβ1-4(Fucα1-3)GlcNAcβ1-R) and Ley (Fucα1-2 Galβ1-4(Fucα1-3)GlcNAcβ1-R). The reorganization of the glycocalyx induced by viral infection may favor the spread of viral progeny, and alter diverse biological functions mediated by glycans, including recognition by the adaptive immune system.

Diagnostic Parameters of Adenoviremia in Pediatric Stem Cell Transplant Recipients.

Front Microbiol 2019 22;10:414. Epub 2019 Feb 22.

Molecular Microbiology, Children's Cancer Research Institute, Vienna, Austria.

Despite recent progress in the diagnostic risk assessment of human adenovirus (HAdV) infections in immunocompromised patients, clinical complications mediated by these viruses continue contributing to significant morbidity and mortality, particularly in the pediatric hematopoietic allogeneic stem cell transplant (HSCT) setting. Current data highlight the importance of monitoring stool samples to assess the risk of invasive HAdV infections in children undergoing HSCT. The advent of novel, more effective antiviral treatment options might permit successful virus control even at the stage of systemic infection, thus increasing the interest in optimized HAdV monitoring in peripheral blood (PB).

Evaluation of the Antiviral Activity of Sephin1 Treatment and Its Consequences on eIF2α Phosphorylation in Response to Viral Infections.

Front Immunol 2019 12;10:134. Epub 2019 Feb 12.

Université de Toulouse, ENVT, INRA, UMR 1225, Toulouse, France.

The guanabenz derivative Sephin1 has recently been proposed to increase the levels of translation initiation factor 2 (eIF2α) phosphorylation by inhibiting dephosphorylation by the protein phosphatase 1-GADD34 (PPP1R15A) complex. As phosphorylation of eIF2α by protein kinase R (PKR) is a prominent cellular antiviral pathway, we evaluated the consequences of Sephin1 treatment on virus replication. Our results provide evidence that Sephin1 downregulates replication of human respiratory syncytial virus, measles virus, human adenovirus 5 virus, human enterovirus D68, human cytomegalovirus, and rabbit myxoma virus.

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

Detection of adenovirus, papillomavirus and parvovirus in Brazilian bats of the species Artibeus lituratus and Sturnira lilium.

Arch Virol 2019 Apr 10;164(4):1015-1025. Epub 2019 Feb 10.

Instituto Pasteur, Secretaria da Saúde do Governo do estado de São Paulo, Avenida Paulista, 393, Bairro Cerqueira César, São Paulo, São Paulo, 01311-000, Brazil.

Bats play a significant role in maintaining their ecosystems through pollination, dispersal of seeds, and control of insect populations, but they are also known to host many microorganisms and have been described as natural reservoirs for viruses with zoonotic potential. The diversity of viruses in these animals remains largely unknown, however, because studies are limited by species, location, virus target, or sample type. Therefore, the aim of this study was to detect fragments of viral genomes in bat samples. Read More
