742 | What are filamentous bacteriophages genera Inovirua and Plectrovirus? | [
"Title: Antibody Engineering for Pursuing a Healthier Future\nPassage: Filamentous bacteriophages used in phage display techniques are viruses that belong to the Inoviridae family. There are fewer of these filamentous phages in this genus compared with tailed phages. Inovirus virions are 7 mm in diameter, contain circular DNA enclosed in a protein capsid, and infect both Gram negative and positive bacteria. They do not lyse host cells, instead, they are packed and extrude at the surface .",
"Title: Architectural Insight into Inovirus-Associated Vectors (IAVs) and Development of IAV-Based Vaccines Inducing Humoral and Cellular Responses: Implications in HIV-1 Vaccines\nPassage: Text: Filamentous bacterial viruses are a group of thread-like viruses containing single-stranded DNA genomes. Collectively, they constitute the genus Inovirus in the family Inoviridae, the terms deriving from the Greek word Ίνα for filament , and they are commonly called filamentous bacteriophages. There are over 50 different known individual species of filamentous viruses; the majority of them capable of infecting Gram-negative bacteria. The complex interaction between filamentous phages and their bacterial hosts is specified by receptor organelles that are usually encoded by transmissible plasmids . One of the most intriguing features of inoviruses is that they are assembled at the",
"Title: Beyond phage display: non-traditional applications of the filamentous bacteriophage as a vaccine carrier, therapeutic biologic, and bioconjugation scaffold\nPassage: Long before the identification of filamentous phage, other types of bacteriophage were already being used for antibacterial therapy in the former Soviet Union and Eastern Europe . The filamentous phage, with its nonlytic life cycle, has less obvious clinical uses, despite the fact that the host specificity of Inovirus and Plectrovirus includes many pathogens of medical importance, including Salmonella, E. coli, Shigella, Pseudomonas, Clostridium, and Mycoplasma species.",

"Title: Emergent severe acute respiratory distress syndrome caused by adenovirus type 55 in immunocompetent adults in 2013: a prospective observational study\nPassage: five consecutive patients with severe ARDS with confirmed HAdV-55 infection were included. All five patients were immunocompetent young men with a median age of 32 years. The mean time from onset to dyspnea was 5 days. Arterial blood gas analysis at ICU admission revealed profound hypoxia. Mean partial oxygen pressure/fraction of inspired oxygen was 58.1. Mean durations from onset to a single-lobe consolidation shown on chest X-rays and, from the first positive CXR to bilateral multilobar lung infiltrates, were 2 days and 4.8 days, respectively.

Four patients received venovenous ECMO. Four of the five patients died despite receiving appropriate respiratory support. CONCLUSIONS: HAdV-55 may cause severe ARDS in immunocompetent young men. Persistent high fever, dyspnea and rapid progression to respiratory failure within 2 weeks, together with bilateral consolidations and infiltrates, are the most frequent clinical manifestations of HAdV-55-induced severe ARDS. Viral load monitoring may help predict disease severity and outcome. The"

"Title: The protective and pathogenic roles of IL-17 in viral infections: friend or foe?\nPassage: An expansive history of evidence has revealed the essential role of the host immune system in preventing viral infections . The initial sensing of an invading virus by pattern recognition receptors of the host innate immune system induces the production of interferons and other proinflammatory cytokines as a part of the early host antiviral response phase. Afterwards, both the activation of cytotoxic T lymphocytes and B-cell production of neutralizing antibodies ultimately mounts an effective and specific antiviral response for optimal viral clearance. However, despite the essential need for viral control and clearance, the intensity of the antiviral immune response must",

"Title: A mathematical model for simulating the phase-based transmissibility of a novel coronavirus\nPassage: Researches showed that the R 0 of severe acute respiratory syndrome was about 2.7-3.4 or 2-4 in Hong Kong, China . Another research found that the R 0 of SARS was about 2.1 in Hong Kong, China, 2.7 in Singapore, and 3.8 in Beijing, China . Therefore, we believe that the commonly acceptable average value of the R 0 of SARS might be 2.9 . The transmissibility of the Middle East respiratory syndrome is much lower than SARS. The reported value of the R 0 of MERS was about 0.8-1.3 , with the inter-human transmissibility of the disease was about",

Six known values of R 0 are 2.05, 2.58, 3.12 1.51, 1.52 and 1.53, respectively. In Fig 1A, we show that model B with age structure yields a better estimate of R 0 and converges at the true value more quickly in the early phase of the epidemic over non-age-structured model A . Between day 9 and day 15, the estimated R 0 values fluctuate~0.4% around the true value. Between day 0 and day 15, less than 100",

"Title: Programmed Death (PD)-1-Deficient Mice Are Extremely Sensitive to Murine Hepatitis Virus Strain-3 (MHV-3) Infection\nPassage: MHV-3 is a single-stranded, positive-sense RNA virus that belongs to the Coronaviridae family. In inbred laboratory mice, the virus produces strain-dependent disease profiles that depend on the infection route, age, genetic background, and immune status of the host. For example, Balb/c, C57BL/6 and DBA/2 mice develop acute fulminant hepatitis, while C3H mice develop a mild chronic disease and mice of the A strain exhibit no evidence of hepatitis . In contrast to the resistant A strain mice, FH induced by MHV-3 in susceptible mice is characterized by the presence of sinusoidal thrombosis and hepatocellular necrosis . These pathological findings occur",

Conversely, injection of a the combination of anti-IFNc and anti-TNF-a blocking mAbs was able to successfully inhibit fgl2 mRNA transcription and protein expression, resulting in reduced tissue damage and significantly protecting against MHV-3-mediated mortality in these mice. These results demonstrated that up-regulation of FGL2 in PD-1-deficient mice after MHV-3 infection was controlled, at least partially, by IFN-c and TNF-a.",

However, these methods are not applicable for our purpose, because our samples contain antibody mixtures. In addition, the amount",
"Title: Efficient Qualitative and Quantitative Determination of Antigen-induced Immune Responses\nPassage: interactions between mouse serum IgGs and human IL-13. The binding interactions were monitored over 10-min association periods followed by 45-min dissociation periods. The binding response curves were obtained by measuring the binding of human IL-13 to IgGs captured on the biosensor surface that were titrated by 2-fold dilutions as follows: 100 nM ; 50 nM ; 25 nM ; 12.5 nM ; and 6.25 nM . Kinetic fit was performed on serum samples D and F-I using the 1:1 Langmuir kinetic binding model in the ProteOn analysis software, as illustrated by the black lines that overlay the response curves.",
"Title: Efficient Qualitative and Quantitative Determination of Antigen-induced Immune Responses\nPassage: concentrations showed that the sensitivity of the method was ϳ31 ng of antigen-specific IgG per l of serum. This high sensitivity can facilitate the detection of less abundant IgGs exhibiting unique epitopes, maximizing the diversity of antibodies that can be recovered. After establishing the highly sensitive SPR and HDX LC/MS methods for detecting antigen-specific antibodies in serum, we tested their performance using sera from immunized mice. Nine serum samples collected from various strains of mice, which were immunized with human IL-13 using different protocols, were analyzed with these methods in a \"proof-of-concept\" study. These samples were previously classified as binders",

Nelson and Worobey discussed different lines of evidence informing the origins of the 1918 virus, including the genetic make-up of the 1918 virus and other pandemic strains, the characteristics of influenza receptors across different influenza hosts, and the frequency of cross-species transmission events. They concluded that the pandemic virus must have emerged in mammals just before 1918, most likely"

"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: SARS-CoV that includes the split orf8b , civet SARS-CoV , two bat SARS-related-CoV containing full-length orf8 , 2019-nCoV, the other two closest bat SARS-related-CoV to 2019-nCoV SL-CoV ZXC21 and ZC45), and bat SARS-related-CoV HKU3-1 ). As expected, orf8 derived from 2019-nCoV belongs to the group that includes the closest genome sequences of bat SARS-related-CoV ZXC21 and ZC45. Interestingly, the new 2019-nCoV orf8 is distant from the conserved orf8 or Figure 5 ) which was shown to trigger intracellular stress pathways and activates NLRP3 inflammasomes , but this is absent in this novel orf8 of 2019-nCoV. Based on a secondary structure",
"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: The genome of 2019-nCoV has overall 89% nucleotide identity with bat SARS-related-CoV SL-CoVZXC21 , and 82% with human SARS-CoV BJ01 2003 and human SARS-CoV Tor2 . The phylogenetic trees constructed using the amino acid sequences of orf1a/b and the 4 structural genes were shown ). For all these 5 genes, the 2019-nCoV was clustered with lineage B βCoVs. It was most closely related to the bat SARS-related CoVs ZXC21 and ZC45 found in Chinese horseshoe",
"Title: Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan\nPassage: Yunnan strains such as the WIV1 had no such deletions and can use human ACE2 as a cellular entry receptor. It is interesting to note that the two bat SARS-related coronavirus ZXC21 and ZC45, being closest to 2019-nCoV, can infect suckling rats and cause inflammation in the brain tissue, and pathological changes in lung & intestine. However, these two viruses could not be isolated in Vero E6 cells and were not investigated further. The two retained deletion sites in the Spike genes of ZXC21 and ZC45 may lessen their likelihood of jumping species barriers imposed by receptor specificity.",
"Title: A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus (2019-nCoV) infected pneumonia (standard version)\nPassage: Wild animal, bats is the most possible host of the 2019-nCoV. It requires further confirmation whether pneumonia infected by the 2019-nCoV is transmitted directly from bats or through an intermediate host. It is believed that clarifying the source of the virus will help determine zoonotic transmission patterns ."

"Title: CEACAM1 in Liver Injury, Metabolic and Immune Regulation\nPassage: CEACAM1 is the only member of the CEA family that is expressed on activated CD4 + and CD8 + T cells, where it is rapidly upregulated upon TCR stimulation . In naive CD4 + T cells, CEACAM1 is expressed at very low levels, and is stored intracellularly in endosomal compartments . In activated T cells, CEACAM1 shows overlapping expression kinetics with the activation marker CD69 and precedes the expression of cytotoxic T-lymphocyte-associated protein 4 . This indicates that the inhibitory form, CEACAM1-L, can interfere with T cell activation prior to CTLA-4, and is therefore, an independent immune checkpoint regulator. CEACAM1-S",

CEACAM1 is expressed by a broad range of cell types, including angiogenically activated endothelia/lymphendothelia, various leukocyte subpopulations, normal epithelial cells and tumour cells 16 . Although Ceacam1 À / À mice do not exhibit this broad CEACAM1 expression, they develop normally and, in the absence of specific challenges, show no signs of disease 27 . CEACAM1 has been described primarily as a regulator of T cells in the gut 20, . Expression of CEACAM1-L inhibits T-cell proliferation and therefore prevents inflammatory bowel disease 30 .

"Title: CEACAM1 in Liver Injury, Metabolic and Immune Regulation\nPassage: CEACAM1 is expressed in T, B, NK, and dentritic cells, and in granulocytes, monocytes and macrophages . In naïve lymphocytes, CEACAM1 is expressed at low levels, but undergoes a rapid upregulation upon cellular activation. In contrast, in granulocytes, CEACAM1 is a differentiation antigen that controls granulopoiesis and delays neutrophil apoptosis . CEACAM1 is generally associated with protection against hyperinflammation that results from either inappropriate expansion of cellular precursors such as in dysregulated granulopoeiesis and neutrophilia in Ceacam1 −/− mice, associated with enhanced IL-1β production in response to stimulation of toll-like receptor 4 or exaggerated effector T cell responses or dysfunctional",

As previously reported , high levels of CEACAM1 expression were detected on blood granulocytes and monocytes with the anti-CEACAM1-specific monoclonal antibody . Cells from Ceacam1 À / À mice stained negative for CEACAM1 . Next, we analysed CEACAM1 expression on lymphoid cells in the blood.

"Title: Comparative Epidemiology of Human Fatal Infections with Novel, High (H5N6 and H5N1) and Low (H7N9 and H9N2) Pathogenicity Avian Influenza A Viruses\nPassage: ranged from 36%-60% overall, which is alarmingly high compared with all previous outbreaks of human cases of seasonal influenza in the United States, for which the CFR has ranged from 0.04%-1.0% . This high level of illness severity and high mortality rate was unexpected and increased disease burden, resulting in concern among clinicians and public health officials; however, the risk factors that are most highly associated with the deaths from avian influenza were not clear.",
