Title A name given to the resource Virus-specific regulatory T cells ameliorate encephalitis by repressing effector T cell functions from priming to effector stages. Creator An entity primarily responsible for making the resource Jingxian Zhao, Jincun Zhao, Stanley Perlman Description An account of the resource Several studies have demonstrated the presence of pathogen-specific Foxp3+ CD4 regulatory T cells (Treg) in infected animals, but little is known about where and how these cells affect the effector T cell responses and whether they are more suppressive than bulk Treg populations. We recently showed the presence of both epitope M133-specific Tregs (M133 Treg) and conventional CD4 T cells (M133 Tconv) in the brains of mice with coronavirus-induced encephalitis. Here, we provide new insights into the interactions between pathogenic Tconv and Tregs responding to the same epitope. M133 Tregs inhibited the proliferation but not initial activation of M133 Tconv in draining lymph nodes (DLN). Further, M133 Tregs inhibited migration of M133 Tconv from the DLN. In addition, M133 Tregs diminished microglia activation and decreased the number and function of Tconv in the infected brain. Thus, virus-specific Tregs inhibited pathogenic CD4 T cell responses during priming and effector stages, particularly those recognizing cognate antigen, and decreased mortality and morbidity without affecting virus clearance. These cells are more suppressive than bulk Tregs and provide a targeted approach to ameliorating immunopathological disease in infectious settings.

Title A name given to the resource Structural bases of coronavirus attachment to host aminopeptidase N and its inhibition by neutralizing antibodies. Creator An entity primarily responsible for making the resource Juan Reguera, César Santiago, Gaurav Mudgal, Desiderio Ordoño, Luis Enjuanes, José M Casasnovas Description An account of the resource The coronaviruses (CoVs) are enveloped viruses of animals and humans associated mostly with enteric and respiratory diseases, such as the severe acute respiratory syndrome and 10-20% of all common colds. A subset of CoVs uses the cell surface aminopeptidase N (APN), a membrane-bound metalloprotease, as a cell entry receptor. In these viruses, the envelope spike glycoprotein (S) mediates the attachment of the virus particles to APN and subsequent cell entry, which can be blocked by neutralizing antibodies. Here we describe the crystal structures of the receptor-binding domains (RBDs) of two closely related CoV strains, transmissible gastroenteritis virus (TGEV) and porcine respiratory CoV (PRCV), in complex with their receptor, porcine APN (pAPN), or with a neutralizing antibody. The data provide detailed information on the architecture of the dimeric pAPN ectodomain and its interaction with the CoV S. We show that a protruding receptor-binding edge in the S determines virus-binding specificity for recessed glycan-containing surfaces in the membrane-distal region of the pAPN ectodomain. Comparison of the RBDs of TGEV and PRCV to those of other related CoVs, suggests that the conformation of the S receptor-binding region determines cell entry receptor specificity. Moreover, the receptor-binding edge is a major antigenic determinant in the TGEV envelope S that is targeted by neutralizing antibodies. Our results provide a compelling view on CoV cell entry and immune neutralization, and may aid the design of antivirals or CoV vaccines. APN is also considered a target for cancer therapy and its structure, reported here, could facilitate the development of anti-cancer drugs.

Title A name given to the resource A chimeric HS4-SAR insulator (IS2) that prevents silencing and enhances expression of lentiviral vectors in pluripotent stem cells. Creator An entity primarily responsible for making the resource Karim Benabdellah, Alejandra Gutiérrez-Guerrero, Marien Cobo, Pilar Muñoz, Francisco Martín Description An account of the resource Chromatin insulators, such as the chicken β-globin locus control region hypersensitive site 4 (HS4), and scaffold/matrix attachment regions (SARs/MARs) have been incorporated separately or in combination into retroviral vectors (RVs) in order to increase transgene expression levels, avoid silencing and reduce expression variability. However, their incorporation into RVs either produces a reduction on titer and/or expression levels or do not have sufficient effect on stem cells. In order to develop an improved insulator we decided to combine SAR elements with HS4 insulators. We designed several synthetic shorter SAR elements containing 4 or 5 MAR/SARs recognition signatures (MRS) and studied their effects on a lentiviral vector (LV) expressing eGFP through the SFFV promoter (SE). A 388 bp SAR element containing 5 MRS, named SAR2, was as efficient or superior to the other SARs analyzed. SAR2 enhanced transgene expression and reduced silencing and variability on human embryonic stem cells (hESCs). We next compared the effect of different HS4-based insulators, the HS4-Core (250 bp), the HS4-Ext (400 bp) and the HS4-650 (650 bp). All HS4 elements reduced silencing and expression variability but they also had a negative effect on transgene expression levels and titer. In general, the HS4-650 element had a better overall effect. Based on these data we developed a chimeric insulator, IS2, combining the SAR2 and the HS4-650. When incorporated into the 3' LTR of the SE LV, the IS2 element was able to enhance expression, avoid silencing and reduce variability of expression on hESCs. Importantly, these effects were maintained after differentiation of the transduced hESCs toward the hematopoietic linage. Neither the HS4-650 nor the SAR2 elements had these effects. The IS2 element is therefore a novel insulator that confers expression stability and enhances expression of LVs on stem cells.

Title A name given to the resource The 3'-terminal 55 nucleotides of bovine coronavirus defective interfering RNA harbor cis-acting elements required for both negative- and positive-strand RNA synthesis. Creator An entity primarily responsible for making the resource Wei-Yu Liao, Ting-Yung Ke, Hung-Yi Wu Description An account of the resource The synthesis of the negative-strand [(-)-strand] complement of the ∼30 kilobase, positive-strand [(+)-strand] coronaviral genome is a necessary early step for genome replication. The identification of cis-acting elements required for (-)-strand RNA synthesis in coronaviruses, however, has been hampered due to insufficiencies in the techniques used to detect the (-)-strand RNA species. Here, we employed a method of head-to-tail ligation and real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) to detect and quantitate the synthesis of bovine coronavirus (BCoV) defective interfering (DI) RNA (-) strands. Furthermore, using the aforementioned techniques along with Northern blot assay, we specifically defined the cis-acting RNA elements within the 3'-terminal 55 nucleotides (nts) which function in the synthesis of (-)- or (+)-strand BCoV DI RNA. The major findings are as follows: (i) nts from -5 to -39 within the 3'-terminal 55 nts are the cis-acting elements responsible for (-)-strand BCoV DI RNA synthesis, (ii) nts from -3 to -34 within the 3'-terminal 55 nts are cis-acting elements required for (+)-strand BCoV DI RNA synthesis, and (iii) the nucleotide species at the 3'-most position (-1) is important, but not critical, for both (-)- and (+)-strand BCoV DI RNA synthesis. These results demonstrate that the 3'-terminal 55 nts in BCoV DI RNA harbor cis-acting RNA elements required for both (-)- and (+)-strand DI RNA synthesis and extend our knowledge on the mechanisms of coronavirus replication. The method of head-to-tail ligation and qRT-PCR employed in the study may also be applied to identify other cis-acting elements required for (-)-strand RNA synthesis in coronaviruses.

Title A name given to the resource Peptides corresponding to the predicted heptad repeat 2 domain of the feline coronavirus spike protein are potent inhibitors of viral infection. Creator An entity primarily responsible for making the resource I-Jung Liu, Wan-Ting Tsai, Li-En Hsieh, Ling-Ling Chueh Description An account of the resource BACKGROUND: Feline infectious peritonitis (FIP) is a lethal immune-mediated disease caused by feline coronavirus (FCoV). Currently, no therapy with proven efficacy is available. In searching for agents that may prove clinically effective against FCoV infection, five analogous overlapping peptides were designed and synthesized based on the putative heptad repeat 2 (HR2) sequence of the spike protein of FCoV, and the antiviral efficacy was evaluated. METHODS: Plaque reduction assay and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) cytotoxicity assay were performed in this study. Peptides were selected using a plaque reduction assay to inhibit Feline coronavirus infection. RESULTS: The results demonstrated that peptide (FP5) at concentrations below 20 μM inhibited viral replication by up to 97%. The peptide (FP5) exhibiting the most effective antiviral effect was further combined with a known anti-viral agent, human interferon-α (IFN-α), and a significant synergistic antiviral effect was observed. CONCLUSION: Our data suggest that the synthetic peptide FP5 could serve as a valuable addition to the current FIP prevention methods.

Title A name given to the resource SPRi-based strategy to identify specific biomarkers in systemic lupus erythematosus, rheumatoid arthritis and autoimmune hepatitis. Creator An entity primarily responsible for making the resource Elvire Beleoken, Hervé Leh, Armelle Arnoux, Béatrice Ducot, Claude Nogues, Eleonora De Martin, Catherine Johanet, Didier Samuel, Mohammad Zahid Mustafa, Jean-Charles Duclos-Vallée, Malcolm Buckle, Eric Ballot Description An account of the resource BACKGROUND: Heterogeneous nuclear ribonucleoprotein (hnRNP) A2/B1 is a target for antinuclear autoantibodies in systemic Lupus erythematosus (SLE), rheumatoid arthritis (RA), and autoimmune hepatitis (AIH). AIM: To monitor molecular interactions between peptides spanning the entire sequence of hnRNP A2/B1 and sera from patients and healthy controls. METHODS: Sera from 8 patients from each pathology and controls were passed across a surface plasmon resonance Imagery (SPRi) surface containing 39 overlapping peptides of 17 mers covering the human hnRNP B1. Interactions involving the immobilised peptides were followed in real time and dissociation rate constants k(off) for each interaction were calculated. RESULTS: Several significant interactions were observed: i) high stability (lower k(off) values) between P₅₅₋₇₀ and the AIH sera compared to controls (p= 0.003); ii) lower stability (higher k(off) values) between P₁₁₈₋₁₃₃ and P₂₆₂₋₂₇₇ and SLE sera, P₁₄₅₋₁₆₀ and RA sera compared to controls (p=0.006, p=0.002, p=0.007). The binding curves and k(off) values observed after the formation of complexes with anti-IgM and anti-IgG antibodies and after nuclease treatment of the serum indicate that i) IgM isotypes are prevalent and ii) nucleic acids participate in the interaction between anti-hnRNAP B1 and P₅₅₋₇₀ and also between controls and the peptides studied. CONCLUSIONS: These results indicate that P₅₅₋₇₀ of hnRNP B1 is a potential biomarker for AIH in immunological tests and suggest the role of circulating nucleic acids, (eg miRNA), present or absent according to the autoimmune disorders and involved in antigen-antibody stability.

Title A name given to the resource High Prevalence and Putative Lineage Maintenance of Avian Coronaviruses in Scandinavian Waterfowl. Creator An entity primarily responsible for making the resource Michelle Wille, Shaman Muradrasoli, Anna Nilsson, Josef D. Järhult Description An account of the resource Coronaviruses (CoVs) are found in a wide variety of wild and domestic animals, and constitute a risk for zoonotic and emerging infectious disease. In poultry, the genetic diversity, evolution, distribution and taxonomy of some coronaviruses have been well described, but little is known about the features of CoVs in wild birds. In this study we screened 764 samples from 22 avian species of the orders Anseriformes and Charadriiformes in Sweden collected in 2006/2007 for CoV, with an overall CoV prevalence of 18.7%, which is higher than many other wild bird surveys. The highest prevalence was found in the diving ducks--mainly Greater Scaup (Aythya marila; 51.5%)--and the dabbling duck Mallard (Anas platyrhynchos; 19.2%). Sequences from two of the Greater Scaup CoV fell into an infrequently detected lineage, shared only with a Tufted Duck (Aythya fuligula) CoV. Coronavirus sequences from Mallards in this study were highly similar to CoV sequences from the sample species and location in 2011, suggesting long-term maintenance in this population. A single Black-headed Gull represented the only positive sample from the order Charadriiformes. Globally, Anas species represent the largest fraction of avian CoV sequences, and there seems to be no host species, geographical or temporal structure. To better understand the eitiology, epidemiology and ecology of these viruses more systematic surveillance of wild birds and subsequent sequencing of detected CoV is imperative.

Title A name given to the resource Building the road to a regional zoonoses strategy: A survey of zoonoses programmes in the Americas. Creator An entity primarily responsible for making the resource Melody J. Maxwell, Mary H Freire de Carvalho, Armando E. Hoet, Marco A.N. Vigilato, Julio C Pompei, Ottorino Cosivi, Víctor J. Del Rio Vilas Description An account of the resource BACKGROUND:In recent years, global public health security has been threatened by zoonotic disease emergence as exemplified by outbreaks of H5N1 and H1N1 influenza, SARS, and most recently Ebola and Zika. Additionally, endemic zoonoses, such as rabies, burden countries year after year, placing demands on limited finances and personnel. To survey the baseline status of the emerging and endemic zoonoses programmes of the Latin American and the Caribbean (LAC) countries, the Pan American Health Organization (PAHO) conducted a survey of priority emerging and endemic zoonoses, countries´ prioritization criteria and methodologies, and suggestions to strengthen countries capacities and regional approaches to zoonoses control. METHODS:A fillable online questionnaire was sent to the zoonoses programme managers of the Ministries of Health (MOH) and Ministries of Agriculture (MAg) of 33 LAC countries from January to April of 2015. The questionnaire comprised 36 single, multiple choice and open-ended questions to inform the objectives of the survey. A descriptive exploratory analysis was completed. RESULTS:Fifty-four ministries (26 MOH, 25 MAg, and 3 combined responses) in 31 LAC countries responded to the survey. Within the ministries, 22 (85%) MOH, 5 (20%) MAg, and 2 (67%) combined entities indicated they had specialized zoonoses units. For endemic zoonoses, 32 of 54 ministries responded that they conduct formal prioritization exercises, most of them annually (69%). The three priority endemic zoonoses for the MOHs were leptospirosis, rabies, and brucellosis while the three priorities for the MAgs were brucellosis, rabies, and tuberculosis. Diagnosis for rabies and leptospirosis were cited as the capacities most in need of development. The most needed cross-cutting capacity was coordination between stakeholders. For emerging zoonoses, 28 ministries performed formal prioritization exercises. The top prioritization criteria were probability of introduction into the country and impact. The three priority emerging zoonoses for the MOHs were Ebola viral disease, avian influenza, and Chikungunya while for the MAgs were avian influenza, bovine spongiform encephalopathy and West Nile virus disease. Surveillance for avian influenza and Ebola, and diagnosis for BSE were quoted as the capacities most needed. For all zoonoses, the majority of respondents (69%) ranked their relationship with the other Ministry as productive or very productive, and 31% minimally productive. Many countries requested a formal regional network, better regional communication and collaboration, and integrated surveillance. CONCLUSIONS:The survey is the first comprehensive effort to date to inform the status of zoonoses programmes in LAC. The information collected here will be used to develop a regional strategy for zoonoses (both endemic and emerging), increase efforts, advocacy, and promote prompt identification and management of EIDs and improvement of endemic programmes.

Title A name given to the resource Host tissue and glycan binding specificities of avian viral attachment proteins using novel avian tissue microarrays. Creator An entity primarily responsible for making the resource Iresha N Ambepitiya Wickramasinghe, Robert P. de Vries, Amber M Eggert, Nantaporn Wandee, Cornelis A.M. De Haan, Andrea Gröne, Monique H. Verheije Description An account of the resource The initial interaction between viral attachment proteins and the host cell is a critical determinant for the susceptibility of a host for a particular virus. To increase our understanding of avian pathogens and the susceptibility of poultry species, we developed novel avian tissue microarrays (TMAs). Tissue binding profiles of avian viral attachment proteins were studied by performing histochemistry on multi-species TMA, comprising of selected tissues from ten avian species, and single-species TMAs, grouping organ systems of each species together. The attachment pattern of the hemagglutinin protein was in line with the reported tropism of influenza virus H5N1, confirming the validity of TMAs in profiling the initial virus-host interaction. The previously believed chicken-specific coronavirus (CoV) M41 spike (S1) protein displayed a broad attachment pattern to respiratory tissues of various avian species, albeit with lower affinity than hemagglutinin, suggesting that other avian species might be susceptible for chicken CoV. When comparing tissue-specific binding patterns of various avian coronaviral S1 proteins on the single-species TMAs, chicken and partridge CoV S1 had predominant affinity for the trachea, while pigeon CoV S1 showed marked preference for lung of their respective hosts. Binding of all coronaviral S1 proteins was dependent on sialic acids; however, while chicken CoV S1 preferred sialic acids type I lactosamine (Gal(1-3)GlcNAc) over type II (Gal(1-4)GlcNAc), the fine glycan specificities of pigeon and partridge CoVs were different, as chicken CoV S1-specific sialylglycopolymers could not block their binding to tissues. Taken together, TMAs provide a novel platform in the field of infectious diseases to allow identification of binding specificities of viral attachment proteins and are helpful to gain insight into the susceptibility of host and organ for avian pathogens.

Title A name given to the resource Development and application of an ELISA for the detection of porcine deltacoronavirus IgG antibodies. Creator An entity primarily responsible for making the resource Anil Thachil, Priscilla F. Gerber, Chao-Ting Xiao, Yaowei Huang, Tanja Opriessnig Description An account of the resource Porcine deltacoronavirus (PDCoV), also known as porcine coronavirus HKU15, was first detected in North America in early 2014 and associated with enteric disease in pigs, resulting in an urgent need to further investigate the ecology of this virus. While assays detecting nucleic acids were implemented quickly, assays to detect anti-PDCoV antibodies have not been available. In this study, an indirect anti-PDCoV IgG enzyme-linked immunosorbent assay (ELISA) based on the putative S1 portion of the spike protein was developed and utilized to determine the prevalence of anti-PDCoV IgG in U.S. pigs. The diagnostic sensitivity of the PDCoV ELISA was 91% with a diagnostic specificity of 95%. A total of 968 serum samples were tested including samples with confirmed infection with PDCoV, porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus or porcine respiratory coronavirus. There was no cross-reactivity with any of the other coronaviruses. Among 355 arbitrarily selected serum samples collected in 2014 and originating from 51 farms across 18 U.S. states, anti-PDCoV IgG antibodies were detected in 8.7% of the samples and in 25.5% of the farms whereas anti-PEDV IgG was detected in 22.8% of the samples and in 54.9% of the farms. In addition, anti-PDCoV IgG antibodies were detected in archived samples collected in 2010, perhaps indicating an earlier undetected introduction into the U.S. pig population. Overall, the obtained data suggest that PDCoV seroprevalence in U.S. pigs is lower compared to PEDV and PDCoV may have been introduced to the U.S. prior to PEDV.
