    viruses Review A Look into Bunyavirales Genomes: Functions of Non-Structural (NS) Proteins Shanna S. Leventhal, Drew Wilson, Heinz Feldmann and David W. Hawman * Laboratory of Virology, Rocky Mountain Laboratories, Division of Intramural Research, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Hamilton, MT 59840, USA; [email protected] (S.S.L.); [email protected] (D.W.); [email protected] (H.F.) * Correspondence: [email protected]; Tel.: +1-406-802-6120 Abstract: In 2016, the Bunyavirales order was established by the International Committee on Taxon- omy of Viruses (ICTV) to incorporate the increasing number of related viruses across 13 viral families. While diverse, four of the families (Peribunyaviridae, Nairoviridae, Hantaviridae, and Phenuiviridae) contain known human pathogens and share a similar tri-segmented, negative-sense RNA genomic organization. In addition to the nucleoprotein and envelope glycoproteins encoded by the small and medium segments, respectively, many of the viruses in these families also encode for non-structural (NS) NSs and NSm proteins. The NSs of Phenuiviridae is the most extensively studied as a host interferon antagonist, functioning through a variety of mechanisms seen throughout the other three families. In addition, functions impacting cellular apoptosis, chromatin organization, and transcrip- tional activities, to name a few, are possessed by NSs across the families. Peribunyaviridae, Nairoviridae, and Phenuiviridae also encode an NSm, although less extensively studied than NSs, that has roles in antagonizing immune responses, promoting viral assembly and infectivity, and even maintenance of infection in host mosquito vectors. Overall, the similar and divergent roles of NS proteins of these Citation: Leventhal, S.S.; Wilson, D.; human pathogenic Bunyavirales are of particular interest in understanding disease progression, viral Feldmann, H.; Hawman, D.W.

The workers’ right to a high level of protection of their health and safety at work and to a working environment that is adapted to their professional needs and that enables them to prolong their participation in the labour market includes protection from exposure to biological agents at work. (2) The implementation of the directives related to the health and safety of workers at work, including Directive 2000/54/EC, was the subject of an ex-post evaluation, referred to as a REFIT evaluation. The evaluation looked at the directives’ relevance, at research and at new scientific knowledge in the various fields concerned. The REFIT evaluation, referred to in the Commission Staff Working Document (3), concludes, among other things, that the classified list of biological agents in Annex III to Directive 2000/54/EC needs to be amended in light of scientific and technical progress and that consistency with other relevant directives should be enhanced.

HERMAN NIEMEYER Breast Cancer Genetics in Chile and Latin America: the history of colonization associated to founder mutations Carvallo, Pilar1. (1) Biología Celular y Molecular, Facultad de Ciencias Biológicas, Pontificia Universidad Católica de Chile Breast cancer is one of the first causes of death by cancer in Chile as in many countries in Latin America. The incidence of breast cancer in Latin American populations varies between 24/100,000 a 71/100,000, being Argentina, Uruguay and Brazil, countries with the highest incidence. This high incidence of breast cancer is associated to the European component, as it has been demonstrated in different studies among Hispanic populations. In relation to genetics, since 2000 the screening of BRCA1 and BRCA2 gene mutations has been performed in several Latin American countries, in women with hereditary breast cancer. Mutations in these two genes have been found in all populations studied until today, finding a 13.7% to 26.3% of mutation carriers among women with hereditary breast cancer. Only few populations share some mutations: Brazil/Argentina (13), México/Argentina (8), Chile/Argentina (7) and Chile/Brazil (6). Most mutations in Latin America have been already described in Spain, Portugal and among European populations, in concordance with our history of colonization. Also some founder mutations have been described in Brazil, Mexico, Colombia, being the most striking finding the 9 founder mutations in Chilean population.

  • Ecology of Neglected Rodent-Borne American Orthohantaviruses
    pathogens Review Ecology of Neglected Rodent-Borne American Orthohantaviruses Nathaniel Mull 1,*, Reilly Jackson 1, Tarja Sironen 2,3 and Kristian M. Forbes 1 1 Department of Biological Sciences, University of Arkansas, Fayetteville, AR 72701, USA; [email protected] (R.J.); [email protected] (K.M.F.) 2 Department of Virology, University of Helsinki, 00290 Helsinki, Finland; Tarja.Sironen@helsinki.fi 3 Department of Veterinary Biosciences, University of Helsinki, 00790 Helsinki, Finland * Correspondence: [email protected] Received: 9 April 2020; Accepted: 24 April 2020; Published: 26 April 2020 Abstract: The number of documented American orthohantaviruses has increased significantly over recent decades, but most fundamental research has remained focused on just two of them: Andes virus (ANDV) and Sin Nombre virus (SNV). The majority of American orthohantaviruses are known to cause disease in humans, and most of these pathogenic strains were not described prior to human cases, indicating the importance of understanding all members of the virus clade. In this review, we summarize information on the ecology of under-studied rodent-borne American orthohantaviruses to form general conclusions and highlight important gaps in knowledge. Information regarding the presence and genetic diversity of many orthohantaviruses throughout the distributional range of their hosts is minimal and would significantly benefit from virus isolations to indicate a reservoir role. Additionally, few studies have investigated the mechanisms underlying transmission routes and factors affecting the environmental persistence of orthohantaviruses, limiting our understanding of factors driving prevalence fluctuations. As landscapes continue to change, host ranges and human exposure to orthohantaviruses likely will as well. Research on the ecology of neglected orthohantaviruses is necessary for understanding both current and future threats to human health.

  • Comparison of Targeted Next-Generation Sequencing For
    www.nature.com/scientificreports OPEN Comparison of targeted next- generation sequencing for whole- genome sequencing of Hantaan orthohantavirus in Apodemus agrarius lung tissues Jin Sun No1,6, Won-Keun Kim2,3,6, Seungchan Cho1,6, Seung-Ho Lee1, Jeong-Ah Kim1, Daesang Lee4, Dong Hyun Song4, Se Hun Gu4, Seong Tae Jeong4, Michael R. Wiley5, Gustavo Palacios 5 & Jin-Won Song1* Orthohantaviruses, negative-sense single-strand tripartite RNA viruses, are a global public health threat. In humans, orthohantavirus infection causes hemorrhagic fever with renal syndrome or hantavirus cardiopulmonary syndrome. Whole-genome sequencing of the virus helps in identifcation and characterization of emerging or re-emerging viruses. Next-generation sequencing (NGS) is a potent method to sequence the viral genome, using molecular enrichment methods, from clinical specimens containing low virus titers. Hence, a comparative study on the target enrichment NGS methods is required for whole-genome sequencing of orthohantavirus in clinical samples. In this study, we used the sequence-independent, single-primer amplifcation, target capture, and amplicon NGS for whole- genome sequencing of Hantaan orthohantavirus (HTNV) from rodent specimens. We analyzed the coverage of the HTNV genome based on the viral RNA copy number, which is quantifed by real-time quantitative PCR. Target capture and amplicon NGS demonstrated a high coverage rate of HTNV in Apodemus agrarius lung tissues containing up to 103–104 copies/μL of HTNV RNA. Furthermore, the amplicon NGS showed a 10-fold (102 copies/μL) higher sensitivity than the target capture NGS. This report provides useful insights into target enrichment NGS for whole-genome sequencing of orthohantaviruses without cultivating the viruses.

The first annotated genome of orb-weaver spiders, exploring N. clavipes, has been reported recently. This remarkable study, focused primarily in the diversity of silk specific genes, shed light into the complex evolutionary history of spiders. Furthermore, a robust, multiple and tissue specific transcriptome analysis provided a massive resource for N. clavipes RNA survey. Here, I present evidence towards the discovery and characterization of viral sequences corresponding to the first extant virus species associated to N.
