Dengue Fever Strikes Millions. Now Scientists Hope To Strike Back - NPR (blog) | Virology and Bioinformatics from Virology.ca | Scoop.it
It's called "breakbone fever" because that's how bad you feel when you get it. There's no cure. But scientists have found powerful antibodies that could lead to the development of a simple vaccine.

Detailed characterisation of Hendra virus infection of different cell types

Hendra virus (HeV) is a pleomorphic virus belonging to the Paramyxovirus family. Our long-term aim is to understand the process of assembly of HeV virions. As a first step, we sought to determine the most appropriate cell culture system with which to study this process, and then to use this model to define the morphology of the virus and identify the site of assembly by imaging key virus encoded proteins in infected cells.

Virology Journal | Full text | Plant-based vaccines against viruses

Plant-made or “biofarmed” viral vaccines are some of the earliest products of the technology of plant molecular farming, and remain some of the brightest prospects for the success of this field. Proofs of principle and of efficacy exist for many candidate viral veterinary vaccines; the use of plant-made viral antigens and of monoclonal antibodies for therapy of animal and even human viral disease is also well established. This review explores some of the more prominent recent advances in the biofarming of viral vaccines and therapies, including the recent use of ZMapp for Ebolavirus infection, and explores some possible future applications of the technology.

Viral suppressors of the RIG-I-mediated interferon response are pre-packaged in influenza virions : Nature Communications : Nature Publishing Group

Viral suppressors of the RIG-I-mediated interferon response are pre-packaged in influenza virions : Nature Communications : Nature Publishing Group | Virology and Bioinformatics from Virology.ca | Scoop.it

The type I interferon (IFN) response represents the first line of defence to invading pathogens. Internalized viral ribonucleoproteins (vRNPs) of negative-strand RNA viruses induce an early IFN response by interacting with retinoic acid inducible gene I (RIG-I) and its recruitment to mitochondria. Here we employ three-dimensional stochastic optical reconstruction microscopy (STORM) to visualize incoming influenza A virus (IAV) vRNPs as helical-like structures associated with mitochondria. Unexpectedly, an early IFN induction in response to vRNPs is not detected. A distinct amino-acid motif in the viral polymerases, PB1/PA, suppresses early IFN induction. Mutation of this motif leads to reduced pathogenicity in vivo, whereas restoration increases it. Evolutionary dynamics in these sequences suggest that completion of the motif, combined with viral reassortment can contribute to pandemic risks. In summary, inhibition of the immediate anti-viral response is ‘pre-packaged’ in IAV in the sequences of vRNP-associated polymerase proteins.

Herpes Virus Rearranges Telomeres to Improve Viral Replication

Herpes Virus Rearranges Telomeres to Improve Viral Replication | Virology and Bioinformatics from Virology.ca | Scoop.it

A team of scientists, led by researchers at The Wistar Institute, has found that an infection with herpes simplex virus 1 (HSV-1) causes rearrangements in telomeres, small stretches of DNA that serve as protective ends to chromosomes. The findings, which will be published in the Dec. 24 edition of the journal Cell Reports, show that this manipulation of telomeres may explain how viruses like herpes are able to successfully replicate while also revealing more about the protective role that telomeres play against other viruses.

MAVS, cGAS, and endogenous retroviruses in T-independent B cell responses

Scattered across our genome are endogenous retroviruses (ERVs), ancient “footprints” of previous viral infections. Scientists do not fully understand their functions, but Zeng et al. now report a role for ERVs in mobilizing a particular type of B cell–driven immune response in mice (T cell–independent, TID), which is usually mounted in response to viral capids or bacterial polysaccharides (see the Perspective by Grasset and Cerutti). Immunizing mice with a model TID antigen elicited an increase in ERV RNA and DNA in the cytoplasm of B cells. Innate immune receptors that recognize cytoplasmic nucleotides then triggered signaling cascades that resulted in the production of immunoglobulin M.

The U.S. Food and Drug Administration today approved Gardasil 9 (Human Papillomavirus 9-valent Vaccine, Recombinant) for the prevention of certain diseases caused by nine types of Human Papillomavirus (HPV). Covering nine HPV types, five more HPV types than Gardasil (previously approved by the FDA), Gardasil 9 has the potential to prevent approximately 90 percent of cervical, vulvar, vaginal and anal cancers.

Alpharetroviral Vectors: From a Cancer-Causing Agent to a Useful Tool for Human Gene Therapy

Alpharetroviral Vectors: From a Cancer-Causing Agent to a Useful Tool for Human Gene Therapy | Virology and Bioinformatics from Virology.ca | Scoop.it

Gene therapy using integrating retroviral vectors has proven its effectiveness in several clinical trials for the treatment of inherited diseases and cancer. However, vector-mediated adverse events related to insertional mutagenesis were also observed, emphasizing the need for safer therapeutic vectors. Paradoxically, alpharetroviruses, originally discovered as cancer-causing agents, have a more random and potentially safer integration pattern compared to gammaretro- and lentiviruses. In this review, we provide a short overview of the history of alpharetroviruses and explain how they can be converted into state-of-the-art gene delivery tools with improved safety features. We discuss development of alpharetroviral vectors in compliance with regulatory requirements for clinical translation, and provide an outlook on possible future gene therapy applications. Taken together, this review is a broad overview of alpharetroviral vectors spanning the bridge from their parental virus discovery to their potential applicability in clinical settings

Mega2: validated data-reformatting for linkage and association analyses - Source Code for Biology and Medicine

In a typical study of the genetics of a complex human disease, many different analysis programs are used, to test for linkage and association. This requires extensive and careful data reformatting, as many of these analysis programs use differing input formats. Writing scripts to facilitate this can be tedious, time-consuming, and error-prone. To address these issues, the open source Mega2 data reformatting program provides validated and tested data conversions from several commonly-used input formats to many output formats.
