Divergent Evolution of E1A CR3 in Human Adenovirus Species D.

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

Department of Ophthalmology, Howe Laboratory, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, MA 02114, USA.

Adenovirus E1A is the first viral protein expressed during infection. E1A controls critical aspects of downstream viral gene expression and cell cycle deregulation, and its function is thought to be highly conserved among adenoviruses. Various bioinformatics analyses of E1A from 38 human adenoviruses of species D (HAdV-D), including likelihood clade model partitioning, provided highly significant evidence of divergence of HAdV-Ds into two distinct groups for the conserved region 3 (CR3), present only in the E1A 13S isoform.

Expansion of Anti-viral T Cells from Cord Blood by Accelerated Co-cultured Dendritic Cells.

Mol Ther Methods Clin Dev 2019 Jun 31;13:112-120. Epub 2018 Dec 31.

INSERM, U1016, Cochin Institute, Paris 75014, France.

Hematopoietic stem cell transplantation (HSCT) using unrelated cord blood (CB) donors is a suitable approach when an HLA-matched donor is not available. However, one important drawback is the risk of life-threatening viral infections prior to immune reconstitution, particularly from adenoviruses (AdVs). Although adoptive therapy with expanded virus-reactive donor T cells has proven effective to treat these infections in HSCT recipients, the manufacturing process is complex and requires large numbers of cells, which is incompatible with CB donor units.

Optimization of Early Steps in Oncolytic Adenovirus ONCOS-401 Production in T-175 and HYPERFlasks.

Int J Mol Sci 2019 Jan 31;20(3). Epub 2019 Jan 31.

Targovax ASA, Clinical Science, 0283 Oslo, Norway.

Oncolytic adenoviruses can trigger lysis of tumor cells, induce an antitumor immune response, bypass classical chemotherapeutic resistance strategies of tumors, and provide opportunities for combination strategies. A major challenge is the development of scalable production methods for viral seed stocks and sufficient quantities of clinical grade viruses. Because of promising clinical signals in a compassionate use program (Advanced Therapy Access Program) which supported further development, we chose the oncolytic adenovirus ONCOS-401 as a testbed for a new approach to scale up.

Modeling Host-Virus Interactions in Viral Infectious Diseases Using Stem-Cell-Derived Systems and CRISPR/Cas9 Technology.

Viruses 2019 Jan 30;11(2). Epub 2019 Jan 30.

Department of Biological Sciences, Korea Advanced Institute of Science and Technology (KAIST), Daejeon 34141, Korea.

Pathologies induced by viral infections have undergone extensive study, with traditional model systems such as two-dimensional (2D) cell cultures and in vivo mouse models contributing greatly to our understanding of host-virus interactions. However, the technical limitations inherent in these systems have constrained efforts to more fully understand such interactions, leading to a search for alternative in vitro systems that accurately recreate in vivo physiology in order to advance the study of viral pathogenesis. Over the last decade, there have been significant technological advances that have allowed researchers to more accurately model the host environment when modeling viral pathogenesis in vitro, including induced pluripotent stem cells (iPSCs), adult stem-cell-derived organoid culture systems and CRISPR/Cas9-mediated genome editing.

Challenges in management of epidemic keratoconjunctivitis with emerging recombinant human adenoviruses.

J Clin Virol 2019 Jan 11;112:1-9. Epub 2019 Jan 11.

Department of Ophthalmology, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Sapporo, Japan; Department of Ophthalmology, Health Sciences University of Hokkaido, Sapporo, Japan. Electronic address:

Adenoviral epidemic keratoconjunctivitis (EKC) presents as severe conjunctival inflammations involving the cornea that can lead to the development of corneal opacities and blurred vision, which can persist for months. EKC is highly contagious and responsible for outbreaks worldwide, therefore accurate diagnosis and rapid containment are imperative. EKC is caused by a number of types within Human adenovirus species D (HAdV-D): 8, 37 and 64 (formerly known as 19a) and these types were considered the major causes of EKC for over fifty years.

Microbubble-mediated delivery of human adenoviruses does not elicit innate and adaptive immunity response in an immunocompetent mouse model of prostate cancer.

J Transl Med 2019 Jan 11;17(1):19. Epub 2019 Jan 11.

Department of Radiology, University of Mississippi Medical Center, Jackson, MS, 39126, USA.

Background: Gene transfer to malignant sites using human adenoviruses (hAds) has been limited because of their immunogenic nature and host specificity. Murine cells often lack some of the receptors needed for hAds attachment, thus murine cells are generally non-permissive for human adenoviral infection and replication, which limits translational studies.

Methods: We have developed a gene transfer method that uses a combination of lipid-encapsulated perfluorocarbon microbubbles and ultrasound to protect and deliver hAds to a target tissue, bypassing the requirement of specific receptors. Read More

Human adenovirus type 7 infection causes a more severe disease than type 3.

BMC Infect Dis 2019 Jan 9;19(1):36. Epub 2019 Jan 9.

Department of Respiratory Medicine, Children's Hospital of Chongqing Medical University, Chongqing, 400014, China.

Background: Human adenovirus type 3 (HAdV-3) and 7 (HAdV-7) cause significant morbidity and develop severe complications and long-term pulmonary sequelae in children. However, epidemiologic reports have suggested that nearly all highly severe or fatal adenoviral diseases in children are associated with HAdV-7 rather than HAdV-3. Here, we conduct in-depth investigations to confirm and extend these findings through a comprehensive series of assays in vitro and in vivo as well as clinical correlates. Read More

Front Microbiol 2018 10;9:3040. Epub 2018 Dec 10.

State Key Laboratories of Respiratory Diseases, Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, Guangzhou, China.

Human adenoviruses type 4 (HAdV4) and 7 (HAdV7) are two major respiratory pathogens and sporadically cause outbreaks of acute respiratory diseases. The neutralizing antibody (nAb) response to these two adenoviruses in civilian populations, which is important for dissecting previous circulations and predicting potential outbreaks, remains largely unknown. In this study, we generated replication-competent HAdV4 and HAdV7 reporter viruses expressing secreted-alkaline-phosphatase (SEAP), and established neutralization assays to investigate the seroprevalence of pre-existing nAb in healthy volunteers from Hunan Province, southern China.

Exploiting the transcriptional specificity of the alpha-methylacyl-CoA racemase promoter for the molecular imaging of prostate cancer.

Oncotarget 2018 Nov 30;9(94):36693-36704. Epub 2018 Nov 30.

Department of Pharmacology, University of Minnesota, Minneapolis 55455, MN, USA.

The metabolic protein alpha-methylacyl-CoA racemase (AMACR) is significantly overexpressed in prostate cancer compared to the normal prostate and other non-malignant tissue. Though an attractive target, there are no reports in the literature on leveraging the expression of AMACR for the molecular imaging of prostate cancer. Here, we used a molecular-genetic imaging strategy to exploit the transcriptional specificity of the AMACR promoter for the detection of prostate cancer using the reporter gene luciferase. Read More
