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. black stitched shirts
