  2. Neutralizing antibody - Wikipedia

    en.wikipedia.org/wiki/Neutralizing_antibody

    [3] [4] Neutralizing antibodies are part of the humoral response of the adaptive immune system against viruses, bacteria and microbial toxin. By binding specifically to surface structures ( antigen ) on an infectious particle, neutralizing antibodies prevent the particle from interacting with its host cells it might infect and destroy.

  3. Antibody - Wikipedia

    en.wikipedia.org/wiki/Antibody

    Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.

  4. Mucosal immunology - Wikipedia

    en.wikipedia.org/wiki/Mucosal_immunology

    The mucous membranes are in constant contact with microorganisms, food, and inhaled antigens. [2] In healthy states , the mucosal immune system protects the organism against infectious pathogens and maintains a tolerance towards non-harmful commensal microbes and benign environmental substances. [ 1 ]

  5. Microbial food web - Wikipedia

    en.wikipedia.org/wiki/Microbial_food_web

    Bacteria. In the microbial food web, bacteria play a crucial role in breaking down organic materials and recycling nutrients. They transform DOC into bacterial biomass so that protists and other higher trophic levels can consume it. Additionally, bacteria take part in the nitrogen and carbon cycles, among other biogeochemical cycles. [4] Algae

  6. Humoral immunity - Wikipedia

    en.wikipedia.org/wiki/Humoral_immunity

    Humoral immunity is also referred to as antibody-mediated immunity. The study of the molecular and cellular components that form the immune system , including their function and interaction, is the central science of immunology .

  7. Complement system - Wikipedia

    en.wikipedia.org/wiki/Complement_system

    Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane. [1]

    Again, antibiotics only work against bacterial infections. “It does not work against viruses or fungus,” says Tran. “The confusion always comes up around wintertime because of the flu.

  9. Immune system - Wikipedia

    en.wikipedia.org/wiki/Immune_system

    An antibody is made up of two heavy chains and two light chains. The unique variable region allows an antibody to recognize its matching antigen. [73] A B cell identifies pathogens when antibodies on its surface bind to a specific foreign antigen. [74] This antigen/antibody complex is taken up by the B cell and processed by proteolysis into ...
