Epidemiological investigation and phylogenetic analysis of Caprine parainfluenza virus type 3 in sheep of China.

Transbound Emerg Dis 2019 Feb 16. Epub 2019 Feb 16.

State Key Laboratory of Veterinary Etiological Biology, Lanzhou Veterinary Research Institute, China, Academy of Agricultural Sciences, Lanzhou, 730046, China.

Caprine parainfluenza virus type 3 (CPIV3) is a new member of the Respirovirus genus in the Paramyxivirudae family, mainly causing respiratory disease. Up to now, accumulating evidence has focused on CPIV3 infection in goats, with little understood about its epidemiology in sheep. To that end, we collected 1163 sheep sera samples from 9 provinces/autonomous regions in 2012 and 1863 samples from 6 provinces/autonomous regions during 2016-2017, with serological prevalence of 50.

The switch between acute and persistent paramyxovirus infection caused by single amino acid substitutions in the RNA polymerase P subunit.

PLoS Pathog 2019 Feb 11;15(2):e1007561. Epub 2019 Feb 11.

School of Biology, Centre for Biomolecular Sciences, BMS Building, North Haugh, University of St. Andrews, St. Andrews, Fife, United Kingdom.

Paramyxoviruses can establish persistent infections both in vitro and in vivo, some of which lead to chronic disease. However, little is known about the molecular events that contribute to the establishment of persistent infections by RNA viruses. Using parainfluenza virus type 5 (PIV5) as a model we show that phosphorylation of the P protein, which is a key component of the viral RNA polymerase complex, determines whether or not viral transcription and replication becomes repressed at late times after infection.

Nanoparticle-Based Vaccines Against Respiratory Viruses.

Front Immunol 2019 24;10:22. Epub 2019 Jan 24.

Département des Sciences Biologiques, Université du Québec à Montréal, Montreal, QC, Canada.

The respiratory mucosa is the primary portal of entry for numerous viruses such as the respiratory syncytial virus, the influenza virus and the parainfluenza virus. These pathogens initially infect the upper respiratory tract and then reach the lower respiratory tract, leading to diseases. Vaccination is an affordable way to control the pathogenicity of viruses and constitutes the strategy of choice to fight against infections, including those leading to pulmonary diseases. Read More

Angiomotin-Like 1 Links Paramyxovirus M Proteins to NEDD4 Family Ubiquitin Ligases.

Viruses 2019 Jan 31;11(2). Epub 2019 Jan 31.

Department of Veterinary and Biomedical Sciences, The Pennsylvania State University, University Park, PA 16802, USA.

To define the links between paramyxovirus budding and cellular ESCRT machinery, we previously identified angiomotin-like 1 (AMOTL1) in a screen for host factors that bind to the matrix (M) protein of parainfluenza virus 5 (PIV5). This protein harbors three L/PPXY sequences, allowing it to interact with WW domain containing proteins including NEDD4 family members. We hypothesize that paramyxoviruses use AMOTL1 as a linker to indirectly recruit the same NEDD4 ubiquitin ligases for budding that other enveloped viruses recruit directly through their PPXY late domains.

Oral ribavirin for paramyxovirus infection after alemtuzumab-containing reduced-intensity conditioning HCT regimen.

Pediatr Transplant 2019 Jan 27:e13358. Epub 2019 Jan 27.

Department of Pediatrics, Children's Hospital of Pittsburgh of UPMC, Pittsburgh, Pennsylvania.

Aerosolized ribavirin has been used in pediatric immunocompromised patients to treat acute respiratory viral infections, but oral ribavirin may be a less expensive alternative that allows for outpatient therapy. Oral ribavirin has compared favorably to aerosolized ribavirin in adult studies, but data on safety are lacking in pediatric populations. Four cases are described in which oral ribavirin was used to treat viral respiratory infections in recipients of allogeneic hematopoietic stem cell transplants at a Children's Hospital, demonstrating safety and feasibility.

T Lymphocytes as Measurable Targets of Protection and Vaccination Against Viral Disorders.

Int Rev Cell Mol Biol 2019 24;342:175-263. Epub 2018 Oct 24.

Department of Medicine, McGill University, Montréal, QC, Canada; Lady Davis Institute, Jewish General Hospital, Montréal, QC, Canada.

Continuous epidemiological surveillance of existing and emerging viruses and their associated disorders is gaining importance in light of their abilities to cause unpredictable outbreaks as a result of increased travel and vaccination choices by steadily growing and aging populations. Close surveillance of outbreaks and herd immunity are also at the forefront, even in industrialized countries, where previously eradicated viruses are now at risk of re-emergence due to instances of strain recombination, contractions in viral vector geographies, and from their potential use as agents of bioterrorism. There is a great need for the rational design of current and future vaccines targeting viruses, with a strong focus on vaccine targeting of adaptive immune effector memory T cells as the gold standard of immunity conferring long-lived protection against a wide variety of pathogens and malignancies.

Viral-Bacterial Co-infections in the Cystic Fibrosis Respiratory Tract.

Front Immunol 2018 20;9:3067. Epub 2018 Dec 20.

Department of Microbiology and Molecular Genetics, University of Pittsburgh School of Medicine, Pittsburgh, PA, United States.

A majority of the morbidity and mortality associated with the genetic disease Cystic Fibrosis (CF) is due to lung disease resulting from chronic respiratory infections. The CF airways become chronically colonized with bacteria in childhood, and over time commensal lung microbes are displaced by bacterial pathogens, leading to a decrease in microbial diversity that correlates with declining patient health. Infection with the pathogen is a major predictor of morbidity and mortality in CF, with CF individuals often becoming chronically colonized with in early adulthood and thereafter having an increased risk of hospitalization.

Vet Microbiol 2019 Jan 16;228:32-38. Epub 2018 Nov 16.

Division of Avian Infectious Diseases, State Key Laboratory of Veterinary Biotechnology, Harbin Veterinary Research Institute, The Chinese Academy of Agricultural Sciences, Harbin 150069, PR China. Electronic address:

Avian metapneumovirus (aMPV), which has been reported in many countries, causes an acute upper respiratory tract disease in chickens and turkeys. Although aMPV was first detected in China in 1999, there has been no further effort to isolate and characterize the aMPV subtype B (aMPV/B) from field outbreaks. In the present study, we used Vero cells to culture a viral strain, LN16, isolated from chickens with swollen head syndrome. Read More

A novel recombinant attenuated Newcastle disease virus expressing H9 subtype hemagglutinin protected chickens from challenge by genotype VII virulent Newcastle disease virus and H9N2 avian influenza virus.

Vet Microbiol 2019 Jan 16;228:173-180. Epub 2018 Nov 16.

Department of Veterinary Preventive Medicine, College of Veterinary Medicine, Jilin University, Xi'an Road 5333, Changchun, Jilin 130062, China. Electronic address:

Newcastle disease virus (NDV) and H9 subtype avian influenza virus (AIV) are two avian pathogens across the globe. Inasmuch as most poultry flocks worldwide are vaccinated with a live low-virulence or attenuated NDV vaccine, we embarked on the development of vaccine prototypes that would have dual specificities and would allow a single immunization against both avian influenza (AI) and Newcastle disease (ND). Therefore, in the present work, a cloned full-length copy of the genome of the lentogenic NDV strain rmNA-1 was selected as a backbone vector to construct three chimeric NDVs that expressed (i) the ORF encoding the HA, (ii) the ectodomain of HA fused with the transmembrane domain and cytoplasmic tail regions derived from the NDV F protein and (iii) the ectodomain of HA fused with a short GS linker and the GCN4 sequences, and designated as rmNA-H9, rmNA-H9F, and rmNA-H9 (ECTO), respectively.

Modeling the measles paradox reveals the importance of cellular immunity in regulating viral clearance.

PLoS Pathog 2018 12 28;14(12):e1007493. Epub 2018 Dec 28.

Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ, USA.

Measles virus (MV) is a highly contagious member of the Morbillivirus genus that remains a major cause of childhood mortality worldwide. Although infection induces a strong MV-specific immune response that clears viral load and confers lifelong immunity, transient immunosuppression can also occur, leaving the host vulnerable to colonization from secondary pathogens. This apparent contradiction of viral clearance in the face of immunosuppression underlies what is often referred to as the 'measles paradox', and remains poorly understood. Read More

Interferon-induced Transmembrane Protein 1 restricts replication of virus that enter cells via the plasma membrane.

J Virol 2018 Dec 19. Epub 2018 Dec 19.

Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, CB10 1SA, United Kingdom

The acute anti-viral response is mediated by a family of interferon stimulated genes (ISG), providing cell-intrinsic immunity. Mutations in genes encoding these proteins are often associated with increased susceptibility to viral infections. One family of ISGs with anti-viral function are the interferon-inducible transmembrane proteins (IFITM) of which IFITM3 has been studied extensively. Read More

Immunoglobulins and virus antibody titers: of past needs, current requirements, and future options.

Transfusion 2018 Dec;58 Suppl 3:3090-3095

Global Pathogen Safety, Shire (previously Baxter BioScience, Baxalta), Vienna, Austria.

Background: Immunoglobulins (Igs) have been in clinical use for almost 70 years, and early on were also used in conjunction with exposure to the measles virus or polio virus. The US regulations that describe functional Ig lot release thus require the demonstration of minimum antibody titers against these two viruses, although the use of vaccines has now dramatically reduced their incidence. The lower clinical importance of these viruses raises the question of whether other virus antibodies might be more informative for patients with immunodeficiency. Read More
