• 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)
  • protein
  • 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)
  • Methods: Human serum was collected from adults and children followed from birth to 7 years of age, and the serum IgG response to a panel of intestinal microbiota antigens was assessed by using a novel protein microarray. (diva-portal.org)
  • IgG2 represents the major antibody subclass reacting to glycan antigens but IgG1 and IgG3 subclasses have also been observed in such responses, particularly in the case of protein-glycan conjugates. (wikipedia.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)
  • infection
  • Although infection with the laboratory strain of Cpn promotes deposition of amyloid beta, this appears to resolve following reduction of the Cpn antigen burden over time. (pcom.edu)
  • During a streptococcal infection, mature antigen-presenting cells such as B cells present the bacterial antigen to CD4+T cells which differentiate into helper T2 cells. (wikipedia.org)
  • When laboratory services are not available, it may be necessary to administer a combination of drugs, including an amoebicidal drug to kill the parasite and an antibiotic to treat any associated bacterial infection. (wikipedia.org)
  • medical citation needed] Inflammation is commonly associated with a bacterial infection but can also be due to other insults such as repetitive trauma or in rare cases periodontitis. (wikipedia.org)
  • The pulp cavity inherently provides the body with an immune system response challenge, which makes it very difficult for a bacterial infection to be eliminated. (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)
  • lipid
  • the antigen O is assembled to the structure core-lipid A in the periplasm and is later transported toward the outer membrane. (intechopen.com)
  • 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)
  • Conclusions: There is an observed perturbation of the adaptive response to antigens from the microbiota in allergic subjects. (diva-portal.org)
  • Bacterial products may reach the pulp much earlier and begin the inflammatory response. (wikipedia.org)
  • occurs
  • This process occurs on the cytoplasmic side of the internal membrane and c) genes for the assembly of the O antigen and its exportation (orange box). (intechopen.com)
  • 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)
  • Therefore
  • 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)
  • different
  • Despite the high sequence similarity (90% identical on the amino acid level), each subclass has a different half-life, a unique profile of antigen binding and distinct capacity for complement activation. (wikipedia.org)
  • In the case of the species Homo sapiens, for example, there are a significant number of antigens which are different in every individual. (wikipedia.org)
  • types
  • The antigens were initially identified by categorizing and performing massive statistical analyses on interactions between blood types. (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)
  • 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)
