  2. Immunity (medicine) - Wikipedia

    en.wikipedia.org/wiki/Immunity_(medicine)

    Passive immunity is the immunity acquired by the transfer of ready-made antibodies from one individual to another. Passive immunity can occur naturally, such as when maternal antibodies are transferred to the foetus through the placenta, and can also be induced artificially, when high levels of human (or horse ) antibodies specific for a ...

  3. Adaptive immune system - Wikipedia

    en.wikipedia.org/wiki/Adaptive_immune_system

    Artificially Acquired Active Immunity – is done by vaccination (introducing dead or weakened antigen to the host's cell). Artificially Acquired Passive Immunity – This involves the introduction of antibodies rather than antigens to the human body. These antibodies are from an animal or person who is already immune to the disease.

  4. Immune system - Wikipedia

    en.wikipedia.org/wiki/Immune_system

    Adaptive (or acquired) immunity creates an immunological memory leading to an enhanced response to subsequent encounters with that same pathogen. This process of acquired immunity is the basis of vaccination. Dysfunction of the immune system can cause autoimmune diseases, inflammatory diseases and cancer.

  5. Passive immunity - Wikipedia

    en.wikipedia.org/wiki/Passive_immunity

    In immunology, passive immunity is the transfer of active humoral immunity of ready-made antibodies.Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune ...

  7. Antigen-antibody interaction - Wikipedia

    en.wikipedia.org/wiki/Antigen-antibody_interaction

    Immunity developed as an individual is exposed to antigens is called adaptive or acquired immunity, in contrast to immunity developed at birth, which is innate immunity. Acquired immunity depends upon the interaction between antigens and a group of proteins called antibodies produced by B cells of the blood. There are many antibodies and each ...

  8. Adoptive immunity - Wikipedia

    en.wikipedia.org/wiki/Adoptive_immunity

    Adoptive immunity acts in a host after their immunological components are withdrawn, their immunological activity is modified extracorporeally, and then reinfused into the same host. [ 1 ] [ 2 ] This process in its former part is analogous to adoption: a child is once adopted out from their home, grown up, and then returned to their home of birth.

  9. Active immunotherapy - Wikipedia

    en.wikipedia.org/wiki/Active_immunotherapy

    Specific active immunotherapy: the generation of cell-mediated and antibody immune responses focused on specific antigens expressed by the cancer cells, typically using a vaccine platform. [ 5 ] Active immunotherapies fall under the category of activation immunotherapies , which is a subset of immunotherapies that activate the immune system as ...
