WebInnate immunity is based upon a generalized response to known pathogen motifs. Upon recognition of these motifs, the generation of an avid immune response is generated. Most medicines lack these motifs. Note however that if something keeps a more permenant presence in the body, the adaptive arm of immunity can take over. WebDec 24, 2024 · The humoral immune response fights pathogens that are free in the bodily fluids, or “humours”. It relies on antigens (which are also often free in the humours) to detect these pathogens. An antigen is a biomolecule, such as a protein or sugar, that binds to a specific antibody. An antibody/antigen interaction may stimulate an immune response.
