antigen exposure
1Antigen — Each antibody binds to a specific antigen; an interaction similar to a lock and key. An antigen is a foreign molecule that, when introduced into the body, triggers the production of an antibody by the immune system. The immune system will then… …
2antigen — Abbreviation: Ag A macromolecule (usually a protein foreign to the organism), which elicits an immune response on first exposure to the immune system by stimulating the production of antibodies specific to its various antigenic determinants.… …
3antigen — Any substance that, as a result of coming in contact with appropriate cells, induces a state of sensitivity and/or immune responsiveness after a latent period (days to weeks) and that reacts in a demonstrable way with antibodies and/or immune… …

7T helper cell — T helper cells (also known as effector T cells or Th cells) are a sub group of lymphocytes (a type of white blood cell or leukocyte) that plays an important role in establishing and maximizing the capabilities of the immune system. These cells… …
8Immune selective anti-inflammatory derivatives — (ImSAIDs)BackgroundImmune Selective Anti Inflammatory Derivatives (ImSAIDs) are a class of peptides discovered to have diverse biological properties, including potent anti inflammatory properties. ImSAIDs work by altering the activation and… …
9type IV hypersensitivity — A delayed hypersensitivity response (it appears 24 to 48 hours after antigen exposure). It results from the binding of antigen to activated T lymphocytes, which then release cytokines and trigger inflammation and macrophage attacks that damage… …
