• proteins
  • 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)
  • Detection
  • Although work is ongoing to optimize the reaction conditions, and to determine the specificity of this method by challenging the binding of contrast agent with non-specific Ab, the present observations indicate that PAS with specific contrast enhancement is a promising method for in vivo applications, such as detection of bacterial antigens. (arvojournals.org)
  • Detection of Bacterial Antigens and Alzheimer's Disease-like Pathology" by C. Scott Little PhD, Timothy A. Joyce et al. (pcom.edu)
  • protein
  • In this work we have discovered that the negatively charged and hydrophobic surface layer of spores provides a suitable platform for adsorption of protein antigens. (ei-resource.org)
  • The surface omp C protein of S. typhi was responsible for this agglutination, This agglutination maybe promote bacterial entry into epithelial cells. (nii.ac.jp)
  • Here we report the structure-function relationships of Antigen 43 (Ag43a), a prototypic self-associating AT protein from uropathogenic Escherichia coli . (pnas.org)
  • It has the shortest half-life compared to the other IgG subclasses and is frequently present together with IgG1 in response to protein antigens in particular after viral infections. (wikipedia.org)
  • A protein or other substance, such as histocompatibility or red blood cell antigens, that is present in only some members of a species and therefore able to stimulate isoantibody production in other members of the same species who lack it. (wikipedia.org)
  • innate
  • Innate immunity in the pulp is not specific but uses receptors to recognize molecular patterns common to microbes to initiate bacterial killing (phagocytosis). (wikipedia.org)
  • Salmonella
  • 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)
  • 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)
  • occurs
  • Class-switching is mediated by the AID (activation-induced cytidine deaminase) enzyme and only occurs after the B cell binds an antigen through its B cell receptor, and is further activated through interaction with a T helper cell. (wikipedia.org)
  • response
  • Their 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. (nih.gov)
  • The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity. (nih.gov)
  • Bacterial products may reach the pulp much earlier and begin the inflammatory response. (wikipedia.org)
  • present
  • Therefore, it can be thought of as an antigen that is present in some members of the same species, but is not common to all members of that species. (wikipedia.org)
  • cells
  • Bacterial antigens stimulate white blood cells to release MIF into the blood stream. (wikipedia.org)
  • Odontoblasts, (the cells that form dentin) have cellular processes that extend into dentinal tubules and are the first to encounter the caries bacterial antigens. (wikipedia.org)
  • The cells are capable of sensing microbes as well as antigen capture and processing capabilities. (wikipedia.org)
  • In a person with A blood group, the plasma will contain isoantibodies against B antigens, so immediately after transfusion of blood from B group the anti-B isohemagglutinins agglutinate the foreign red blood cells. (wikipedia.org)
  • surface
  • 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. (nii.ac.jp)
  • host
  • Aggregation and biofilm formation are critical mechanisms for bacterial resistance to host immune factors and antibiotics. (pnas.org)
  • blood
  • The anti-A or anti-B isoantibodies or both (also called isohaemagglutinins) are produced by an individual against the antigens (A or B) on the RBCs of other blood groups. (wikipedia.org)
  • System
  • 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)
