Title A name given to the resource Identification and Diagnosis of Newly Emerging Pathogens Creator An entity primarily responsible for making the resource Yan LIU, Xue-jie Yu Description An account of the resource Emerging infectious diseases (EIDs) are newly identified or known infectious diseases that have either expanded in geographic range or increased in infection prevalence over the previous two decades. During the last three decades, more than 30 EIDs have surfaced worldwide, including deadly diseases such as SARS, severe fever with thrombocytopenia syndrome (SFTS), Ebola, Marburg virus disease, Nipah virus disease, hepatitis C, and AIDS.EIDs can not only cause suffering and death in patients but also hinder commercial trade and travel, and create fear or even widespread panic in society. The challenge for the medical community is to effectively recognize and diagnose EIDs. The present study reports our experience in identification and diagnosis of EIDs.

Title A name given to the resource Identification and mapping of linear antibody epitopes in human serum albumin using high-density Peptide arrays. Creator An entity primarily responsible for making the resource Lajla Bruntse Hansen, Søren Buus, Claus Schafer-Nielsen Description An account of the resource We have recently developed a high-density photolithographic, peptide array technology with a theoretical upper limit of 2 million different peptides per array of 2 cm(2). Here, we have used this to perform complete and exhaustive analyses of linear B cell epitopes of a medium sized protein target using human serum albumin (HSA) as an example. All possible overlapping 15-mers from HSA were synthesized and probed with a commercially available polyclonal rabbit anti-HSA antibody preparation. To allow for identification of even the weakest epitopes and at the same time perform a detailed characterization of key residues involved in antibody binding, the array also included complete single substitution scans (i.e. including each of the 20 common amino acids) at each position of each 15-mer peptide. As specificity controls, all possible 15-mer peptides from bovine serum albumin (BSA) and from rabbit serum albumin (RSA) were included as well. The resulting layout contained more than 200.000 peptide fields and could be synthesized in a single array on a microscope slide. More than 20 linear epitope candidates were identified and characterized at high resolution i.e. identifying which amino acids in which positions were needed, or not needed, for antibody interaction. As expected, moderate cross-reaction with some peptides in BSA was identified whereas no cross-reaction was observed with peptides from RSA. We conclude that high-density peptide microarrays are a very powerful methodology to identify and characterize linear antibody epitopes, and should advance detailed description of individual specificities at the single antibody level as well as serologic analysis at the proteome-wide level.

Title A name given to the resource Identification and survey of a novel avian coronavirus in ducks. Creator An entity primarily responsible for making the resource Guiqian Chen, Qingye Zhuang, Kaicheng Wang, Shuo Liu, Jianzhong Shao, Wenming JIANG, Guangyu Hou, Jinping Li, Jianmin Yu, Yiping Li, Jiming Chen Description An account of the resource The rapid discovery of novel viruses using next generation sequencing (NGS) technologies including DNA-Seq and RNA-Seq, has greatly expanded our understanding of viral diversity in recent years. The timely identification of novel viruses using NGS technologies is also important for us to control emerging infectious diseases caused by novel viruses. In this study, we identified a novel duck coronavirus (CoV), distinct with chicken infectious bronchitis virus (IBV), using RNA-Seq. The novel duck-specific CoV was a potential novel species within the genus Gammacoronavirus, as indicated by sequences of three regions in the viral 1b gene. We also performed a survey of CoVs in domestic fowls in China using reverse-transcription polymerase chain reaction (RT-PCR), targeting the viral nucleocapsid (N) gene. A total of 102 CoV positives were identified through the survey. Phylogenetic analysis of the viral N sequences suggested that CoVs in domestic fowls have diverged into several region-specific or host-specific clades or subclades in the world, and IBVs can infect ducks, geese and pigeons, although they mainly circulate in chickens. Moreover, this study provided novel data supporting the notion that some host-specific CoVs other than IBVs circulate in ducks, geese and pigeons, and indicated that the novel duck-specific CoV identified through RNA-Seq in this study is genetically closer to some CoVs circulating in wild water fowls. Taken together, this study shed new insight into the diversity, distribution, evolution and control of avian CoVs.

Title A name given to the resource Identification of a conserved linear B-cell epitope in the M protein of porcine epidemic diarrhea virus Creator An entity primarily responsible for making the resource Zhang Zhibang, Chen Jianfei, Shi-hong Yan, Chen Xiaojin, Shi Da, Feng Li, Yang Bin Description An account of the resource Abstract Background The major structural protein of coronaviruses, the membrane (M) protein, can elicit the formation of protective antibodies, but little information is available about the M protein of porcine epidemic diarrhea virus (PEDV). Identification of epitopes on the PEDV M protein will be helpful in the elucidation of the antigenic properties of this protein. Results One hybridoma cell line secreting anti-M protein monoclonal antibody (McAb) was generated and designated 4D4. To map the epitopes on the PEDV M protein, a total of 17 partially overlapping fragments covering the C-terminus of M protein were expressed as fusion proteins with a 6×His tag or a GST tag. A linear motif, 193TGWAFYVR200, was identified by enzyme-linked immunosorbent assay (ELISA) and western blot (WB) analysis using McAb 4D4. The motif 195WAFYVR200 was the minimal requirement for reactivity, as demonstrated by removing amino acids individually from both ends of the motif 193TGWAFYVR200. The result of WB analysis showed that the 4D4-defined epitope could be recognized by PEDV-positive serum, but not transmissible gastroenteritis virus (TGEV)-positive serum. Furthermore, this epitope was highly conserved among different PEDV strains, as shown by alignment and comparison of sequences. Conclusion A McAb, 4D4, directed against the M protein of PEDV, was obtained, and the 4D4-defined minimal epitope sequence was 195WAFYVR200. The McAb could serve as a candidate for development of a McAb-based antigen capture ELISA for detection of PEDV. The epitope identified provides a basis for the development of epitope-based differential diagnostic techniques and may be useful in the design of epitope-based vaccines.

Title A name given to the resource Identification of a Membrane Binding Peptide in the Envelope Protein of MHV Coronavirus Creator An entity primarily responsible for making the resource Ian M. Jones, Entedar A. J. Alsaadi, Benjamin W. Neuman Description An account of the resource Coronaviruses (CoVs) are enveloped, positive sense, single strand RNA viruses that cause respiratory, intestinal and neurological diseases in mammals and birds. Following replication, CoVs assemble on intracellular membranes including the endoplasmic reticulum Golgi intermediate compartment (ERGIC) where the envelope protein (E) functions in virus assembly and release. In consequence, E potentially contains membrane-modifying peptides. To search for such peptides, the E coding sequence of Mouse Hepatitis Virus (MHV) was inspected for its amino acid conservation, proximity to the membrane and/or predicted amphipathic helices. Peptides identified in silico were synthesized and tested for membrane-modifying activity in the presence of giant unilamellar vesicles (GUVs) consisting of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), sphingomyelin and cholesterol. To confirm the presence of membrane binding peptides identified in the context of a full-length E protein, the wild type and a number of mutants in the putative membrane binding peptide were expressed in Lenti-X-293T mammalian and insect cells, and the distribution of E antigen within the expressing cell was assessed. Our data identify a role for the post-transmembrane region of MHV E in membrane binding.

Title A name given to the resource Identification of a mutation in the spike protein cleavage site in Brazilian strains of wild-type bovine coronavirus Identificação de uma mutação no sítio de clivagem da proteína da espícula em amostras brasileiras de coronavírus bovino Creator An entity primarily responsible for making the resource Elisabete Takiuchi, Marco Antônio Bacellar Barreiros, Alice Fernandes Alfieri, Amauri Alcindo Alfieri Description An account of the resource The spike (S) protein of coronaviruses, a type I membrane glycoprotein, is primarily responsible for entry into susceptible cells by binding with specific receptors on cells and mediating subsequent virus-cell fusion. The bovine coronavirus (BCoV) S protein is cleaved into two subunits, the N-terminal S1 and the C-terminal S2. The proteolytic cleavage site of S protein is highly conserved among BCoV strains and is located between amino acids 763 and 768 (KRRSRR). This study describes a single mutation in the S protein cleavage site of three Brazilian strains of BCoV detected in diarrheic fecal samples from calves naturally infected. The sequenced PCR products revealed that amino acid sequence of the cleavage site of our strains was KRRSSR, indicating a mutation at amino acid position 767 (R ® S). This amino acid substitution occurred due to a single nucleotide substitution in the sequence of DNA corresponding to the proteolytic cleavage site, CGT to AGT. This is the first description of this nucleotide mutation (C to A), which resulted in the substitution of arginine to serine in the S cleavage site. In this study we speculated the probable effects of this mutation in the proteolytic cleavage site using the murine hepatitis coronavirus (MHV) as a comparative model.A proteína da espícula (S), uma glicoproteína de membrana do tipo I, é primariamente responsável pela entrada do vírus em células susceptíveis por meio da interação inicial com receptores celulares específicos e subseqüente mediação da fusão vírus-célula. A proteína S do coronavírus bovino (BCoV) é clivada em duas subunidades: a S1, na região N-terminal e a S2, na região C-terminal. O sítio de clivagem proteolítica da proteína S é altamente conservado entre as estirpes de BCoV e está situado entre os aminoácidos 763-768 (KRRSRR). Este estudo descreve uma mutação no sítio de clivagem da proteína S de três estirpes do BCoV detectadas em amostras fecais diarréicas de bezerros naturalmente infectados no Brasil. O seqüenciamento dos produtos de PCR identificou a seqüência de aminoácidos KRRSSR no sítio de clivagem de nossas amostras, indicando uma mutação na posição 767 (R->S). Esta mutação ocorreu devido a uma única substituição de nucleotídeo no sítio de clivagem proteolítica, alterando o códon CGT para AGT. Esta é a primeira descrição desta mutação de nucleotídeo (C para A), que resultou na substituição do aminoácido arginina por serina no sítio de clivagem da proteína S. Neste estudo também são sugeridos os prováveis efeitos desta mutação no sitio de clivagem proteolítica utilizando o coronavírus da hepatite dos camundongos (MHV) como um modelo comparativo.

Title A name given to the resource Identification of a Novel Betacoronavirus (<i>Merbecovirus</i>) in Amur Hedgehogs from China Creator An entity primarily responsible for making the resource Susanna K.

Lau, Kai-Yuan Cao, Mengfeng Li, Patrick C. Y. Woo, Kwok-yung Yuen Description An account of the resource While dromedaries are the immediate animal source of Middle East Respiratory Syndrome (MERS) epidemic, viruses related to MERS coronavirus (MERS-CoV) have also been found in bats as well as hedgehogs. To elucidate the evolution of MERS-CoV-related viruses and their interspecies transmission pathway, samples were collected from different mammals in China. A novel coronavirus related to MERS-CoV, Erinaceus amurensis hedgehog coronavirus HKU31 (Ea-HedCoV HKU31), was identified from two Amur hedgehogs. Genome analysis supported that Ea-HedCoV HKU31 represents a novel species under Merbecovirus, being most closely related to Erinaceus CoV from European hedgehogs in Germany, with 79.6% genome sequence identity. Compared to other members of Merbecovirus, Ea-HedCoV HKU31 possessed unique non-structural proteins and putative cleavage sites at ORF1ab. Phylogenetic analysis showed that Ea-HedCoV HKU31 and BetaCoV Erinaceus/VMC/DEU/2012 were closely related to NeoCoV and BatCoV PREDICT from African bats in the spike region, suggesting that the latter bat viruses have arisen from recombination between CoVs from hedgehogs and bats. The predicted HKU31 receptor-binding domain (RBD) possessed only one out of 12 critical amino acid residues for binding to human dipeptidyl peptidase 4 (hDPP4), the MERS-CoV receptor. The structural modeling of the HKU31-RBD-hDPP4 binding interphase compared to that of MERS-CoV and Tylonycteris bat CoV HKU4 (Ty-BatCoV HKU4) suggested that HKU31-RBD is unlikely to bind to hDPP4. Our findings support that hedgehogs are an important reservoir of Merbecovirus, with evidence of recombination with viruses from bats. Further investigations in bats, hedgehogs and related animals are warranted to understand the evolution of MERS-CoV-related viruses.

Title A name given to the resource Identification of a novel conserved HLA-A*0201-restricted epitope from the spike protein of SARS-CoV Creator An entity primarily responsible for making the resource Ni Bing, Wang Li, Ruan Zhihua, Lv Yanbo, Wu Yuzhang Description An account of the resource Abstract Background The spike (S) protein is a major structural glycoprotein of coronavirus (CoV), the causal agent of severe acute respiratory syndrome (SARS). The S protein is a potent target for SARS-specific cell-mediated immune responses. However, the mechanism CoV pathogenesis in SARS and the role of special CTLs in virus clearance are still largely uncharacterized. Here, we describe a study that leads to the identification of a novel HLA-A*0201-restricted epitope from conserved regions of S protein. Results First, different SARS-CoV sequences were analyzed to predict eight candidate peptides from conserved regions of the S protein based upon HLA-A*0201 binding and proteosomal cleavage. Four of eight candidate peptides were tested by HLA-A*0201 binding assays. Among the four candidate peptides, Sp8 (S958-966, VLNDILSRL) induced specific CTLs both ex vivo in PBLs of healthy HLA-A2+ donors and in HLA-A2.1/Kb transgenic mice immunized with a plasmid encoding full-length S protein. The immunized mice released IFN-γ and lysed target cells upon stimulation with Sp8 peptide-pulsed autologous dendritic cells in comparison to other candidates. Conclusion These results suggest that Sp8 is a naturally processed epitope. We propose that Sp8 epitope should help in the characterization of mechanisms of virus control and immunopathology in SARS-CoV infection.

Title A name given to the resource Identification of a Novel Inhibitor against Middle East Respiratory Syndrome Coronavirus Creator An entity primarily responsible for making the resource Ya-Ping Sun, Huaidong Zhang, Jian Shi, Zhe Zhang, Rui Gong Description An account of the resource The Middle East respiratory syndrome coronavirus (MERS-CoV) was first isolated in 2012, and circulated worldwide with high mortality. The continual outbreaks of MERS-CoV highlight the importance of developing antiviral therapeutics. Here, we rationally designed a novel fusion inhibitor named MERS-five-helix bundle (MERS-5HB) derived from the six-helix bundle (MERS-6HB) which was formed by the process of membrane fusion. MERS-5HB consists of three copies of heptad repeat 1 (HR1) and two copies of heptad repeat 2 (HR2) while MERS-6HB includes three copies each of HR1 and HR2. As it lacks one HR2, MERS-5HB was expected to interact with viral HR2 to interrupt the fusion step. What we found was that MERS-5HB could bind to HR2P, a peptide derived from HR2, with a strong affinity value (KD) of up to 0.24 nM. Subsequent assays indicated that MERS-5HB could inhibit pseudotyped MERS-CoV entry effectively with 50% inhibitory concentration (IC50) of about 1 μM. In addition, MERS-5HB significantly inhibited spike (S) glycoprotein-mediated syncytial formation in a dose-dependent manner. Further biophysical characterization showed that MERS-5HB was a thermo-stable α-helical secondary structure. The inhibitory potency of MERS-5HB may provide an attractive basis for identification of a novel inhibitor against MERS-CoV, as a potential antiviral agent.
