Publication date: Available online 8 April 2019Source: Antiviral ResearchAuthor(s): John H. Beigel, Hannah H. Nam, Peter L. Adams, Amy Krafft, William L. Ince, Samer S. El-Kamary, Amy C. SimsAbstractThe International Society for Influenza and other Respiratory Virus Diseases held its 6th Antiviral Group (isirv-AVG) conference in Rockville, Maryland, November 13–15, 2018. The three-day program was focused on therapeutics towards seasonal and pandemic influenza, respiratory syncytial virus, coronaviruses including MERS-CoV and SARS-CoV, human rhinovirus, and other respiratory viruses. Updates were presented on several influenza antivirals including baloxavir, CC-42344, VIS410, immunoglobulin, immune plasma, MHAA4549A, pimodivir (JNJ-63623872), umifenovir, and HA minibinders; RSV antivirals including presatovir (GS-5806), ziresovir (AK0529), lumicitabine (ALS-008176), JNJ-53718678, JNJ-64417184, and EDP-938; broad spectrum antivirals such as favipiravir, VH244, remdesivir, and EIDD-1931/EIDD-2801; and host directed strategies including nitazoxanide, eritoran, and diltiazem. Other topics included considerations of novel endpoints such as ordinal scales and patient reported outcomes (PRO), and study design issues, and other regulatory considerations for antiviral drug development. The aim of this report is to provide a summary of the presentations given at this meeting.

The latently infected CD4+CD8- T cells carry the virus through the blood stream and establish lymphomas in the skin, visceral organs and peripheral nerves. The feather follicle epithelium (FFE) is the only anatomical site where fully infectious enveloped virions are produced and ...

Cytokines and chemokines are key signaling molecules of the immune system. Recent technological advances enable measurement of multiplexed cytokine profiles in biological samples. These profiles can then be used to identify potential biomarkers of a variety of clinical phenotypes. However, testing for such associations for each cytokine separately ignores the high context-dependent covariation in cytokine secretion and decreases statistical power to detect associations due to multiple hypothesis testing. Here we present CytoMod - a novel data-driven approach for analysis of cytokine profiles that uses unsupervised clusteri...

Pigs are important livestock and comprehensive understanding of their immune responses in infections is critical to improve vaccines and therapies. Moreover, similarities between human and swine physiology suggest that pigs are a superior animal model for immunological studies. However, paucity of experimental tools for a systematic analysis of the immune responses in pigs represent a major disadvantage. To evaluate the pig as a biomedical model and additionally expand the knowledge of rare immune cell populations in swine, we established a multicolor flow cytometry analysis platform of surface marker expression and cellul...

Authors: Mandil A, Bresee J, Tageldin MA, Azad TM, Khan W Abstract Infectious diseases continue to represent a significant threat to global health security, particularly in the context of increasing globalization, interconnectedness and interdependence. Chief among such threats are influenza viruses and other respiratory pathogens, such as Middle East Respiratory Syndrome coronavirus (MERS-CoV), because of their risk of high transmissibility and acuity of illness. Annual epidemics of seasonal influenza cause an estimated 3-5 million cases of severe illness and more than 500 000 deaths, with the prospect of pandemic...

Semin Respir Crit Care Med 2016; 37: 640-646 DOI: 10.1055/s-0036-1584803In the past two decades, several newly emerging and reemerging viral respiratory pathogens including several influenza viruses (avian influenza and pandemic influenza), severe acute respiratory syndrome coronavirus (SARS-CoV), and Middle East respiratory syndrome coronavirus (MERS-CoV), have continued to challenge medical and public health systems. Thereafter, the development of cost-effective, broad-spectrum antiviral agents is the urgent mission of both virologists and pharmacologists. Current antiviral developments have focused targets on viral entr...

I was asked to write a commentary for the Proceedings of the National Academy of Sciences to accompany an article entitled SARS-like WIV1-CoV poised for human emergence. I’d like to explain why I wrote it and why I spent the last five paragraphs railing against regulating gain-of-function experiments. Towards the end of 2014 the US government announced a pause of gain-of-function research involving research on influenza virus, SARS virus, and MERS virus that “may be reasonably anticipated to confer attributes to influenza, MERS, or SARS viruses such that the virus would have enhanced pathogenicit...

Weber Viruses with pandemic potential including H1N1, H5N1, and H5N7 influenza viruses, and severe acute respiratory syndrome (SARS)/Middle East respiratory syndrome (MERS) coronaviruses (CoV) have emerged in recent years. SARS-CoV, MERS-CoV, and influenza virus can survive on surfaces for extended periods, sometimes up to months. Factors influencing the survival of these viruses on surfaces include: strain variation, titre, surface type, suspending...

Conclusion The use of telemedicine in epidemic situations has a high potential in improving epidemiological investigations, disease control, and clinical case management. However, since it is a recent application, further research would be needed to gain an improved understanding of how telemedicine could be applied in epidemic situations.
