#immune_response__immune_reaction__immunologic_response__immunologicresponse  a bodily defense reaction that recognizes an invading substance (an antigen: such as a virus or fungus or bacteria or transplanted organ) and produces antibodies specific against that antigen
  supertype:  #reaction.bodily_process__response  a bodily process occurring due to the effect of some foregoing stimulus or agent; "a bad reaction to the medicine"; "his responses have slowed with age"
  part:  #complement.enzyme
  subtype:  #anamnestic_response__anamnestic_reaction  renewed rapid production of an antibody on the second (or subsequent) encounter with the same antigen
  subtype:  #humoral_immune_response__humoralimmuneresponse  an immune response (chiefly against bacterial invasion) that is mediated by B cells
  subtype:  #cell-mediated_immune_response  an immune response (chiefly against viral or fungal invasions or transplanted tissue) that involves T cells
  subtype:  #complement_fixation  an immune response in which an antigen-antibody combination inactivates a complement (so it is unavailable to participate in a second antigen-antibody combination)
