WebJan 17, 2024 · The humoral immune response (HIR) is the aspect of immunity mediated by secreted antibodies produced by B cells. Secreted antibodies bind to antigens on the surfaces of invading pathogens, which flag them for destruction. Humoral immunity is so named because it involves substances found in the humors, or body fluids. WebFeb 20, 2011 · Innate 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.
