  • surface antigen
  • A preparation of 1mg/ml of monoclonal antibody (Ab) specific to C. trachomatis surface antigen (Ag) was conjugated to gold nanorods using standard commercial reagents, in order to produce a targeted contrast agent with a strong photoacoustic signal. (arvojournals.org)
  • Vi was maximally expressed inside macrophages, Vi deleted mutants stimulated macrophages during the entry into macrophages and quickly processed by macrophages, This means that S. typhi needs to mask surface antigen to enter macrophage because Vi deleted S, typhi quickly stimulated macrophages.

  • proteins
  • Antigens are frequently conjugated to carrier proteins to amplify their immunogenicity in vivo. (mybiosource.com)
  • Among these, self-antigens comprise mutated or overexpressed proteins. (factmr.com)
  • The s. typhi suppresses surface Vi antigen and produces flagellin and secreted proteins, these factors promote the bacterial invasion from the surface of M cells of Peyer's patches. (nii.ac.jp)
  • Bruyns A-M, De Jaeger G, De Neve M, De Wilde C, Van Montagu M, Depicker A. Bacterial and plant-produced scFv proteins have similar antigen-binding properties. (ugent.be)
  • One mechanism used by bacteria to aggregate and form biofilms involves the expression of self-associating surface-located autotransporter proteins such as Antigen 43 (Ag43). (pnas.org)
  • Despite their abundance and role in bacterial pathogenesis, most AT proteins have not been structurally characterized, and there is a paucity of detailed information with regard to their mode of action. (pnas.org)
  • typhi
  • Salmonella enterica serovar Typhi impairs CD4 T cell responses by reducing antigen availability. (ucdenver.edu)
  • The Vi suppressed S. typhi agglutinate with human blood type antigen. (nii.ac.jp)
  • Publications] Miyake, M., L. Zhao, L. T. Ezaki, K. Hirose, A. Q. Khan, Y. Kawamura, R. Shima, M. Kamijo, T. Masuzawa and Y. Yanagihara: 'Vi-deficient and nonfimbriated mutants of Salmonella typhi agglutinate human blood type antigens and are hyperinvasive. (nii.ac.jp)
  • bacteria
  • Lipopolysaccharide (LPS), a major component on the surface of Gram-negative bacteria, is composed of a lipid A-core and the O-antigen polysaccharide. (diva-portal.org)
  • This suggests that recognition of LPS receptor play a major role to recognize bacterial entry and processing of ingested bacteria. (nii.ac.jp)
  • IgE-reactivity to antigens from gram-positive and negative bacteria is common in patients suffering from respiratory and skin manifestations of allergy, but the routes and mechanisms of sensitisation are not fully understood. (blogspot.com)
  • responses
  • Spores then, should be considered as mucosal adjuvants, most similar to particulate adjuvants, by enhancing responses against soluble antigens. (ei-resource.org)
  • coli
  • S. aureus and E. coli antigens were detected in immune-blotted HDM extract and the presence of IgE-reactive antigens in HDM was demonstrated by qualitative and quantitative IgE inhibition experiments. (blogspot.com)
  • infections
  • other'35ィイD1thィエD1U.S.-Japan cholera and bacterial enteric infections joint panel meeting. (nii.ac.jp)
  • Many persistent and chronic bacterial infections are associated with the formation of large cell aggregates and biofilms that are difficult to treat. (pnas.org)
  • Since 1980 the specific bacteriophages have been used in our Laboratory for the treatment of over 1500 patients with suppurative bacterial infections, in which a routine antibiotic therapy failed. (zeiss.com)
  • intestinal
  • Such unnecessary antibiotic treatment can cause severe side effects like toxicity, allergic reactions, suppression of immune system, intestinal bacterial flora disruption or even, according to the latest studies, obesity. (termedia.pl)
  • immune response
  • Although the term immunogen is often used interchangeably with the term antigen, strictly speaking, only an immunogen is immunogenic and can evoke an immune response. (mybiosource.com)
  • The growing demand for bacterial antigens capable of eliciting a protective immune response against various cancers and infectious diseases is expected to be the major factor driving the growth of the bacterial antigens market over the forecast period. (factmr.com)
  • Its mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. (ebi.ac.uk)
  • carriers
  • Thus, it`s shown the prospect of the use of TI-complexes as a new type of adjuvant carriers for antigens. (msk.ru)
  • bound
  • The photoacoustic spectrum and the conventional optical absorption spectrum of the solution of C. trachomatis antigen bound to the Ab-conjugated nanorods were found to have absorption peaks at ~750nm, which is consistent with the presence of nanorod contrast agent bound on the cuvette walls. (arvojournals.org)
  • vaccine
  • Of these, the use of genetically engineered bacterial spores has been shown to offer promise as both a mucosal as well as a heat-stable vaccine delivery system. (ei-resource.org)
  • A wide range of native state bacterial antigens are in high demand, particularly for vaccine research and in-vitro diagnostics. (factmr.com)

  • diagnostic
  • Major potential end users for bacterial antigens market include hospital associated diagnostic laboratories, diagnostic laboratories and centers and academic and research institutes. (factmr.com)
  • The global market for bacterial antigens is expected to register moderate growth rate over the forecast period on account of an increase in the number of diagnostic tests performed in humans. (factmr.com)
