Polysaccharide antigen with multiple repeating subunits B-cell receptors YY} FIGURE 15.16 T-Independent Antigens Antigens such as some polysaccharides have multiple repeating epitopes. Because of the arrangement of epitopes, clusters of B-cell receptors bind to the antigen simultaneously, leading to B-cell activation without the involvement of TH cells. (YY

Some Type-II immunopathology mediated autoimmune diseases have manifestations inmultiple different organs. Discuss how antibodies to one single antigen can cause damage inmultiple sites throughout the body. Things you might discuss include, but are not limited towhere the antigen could be expressed, how antibodies are made, how they bind antigen,where they circulate, the ratios of antigen to antibody, mechanisms of the immune systemthat result in cellular/tissue damage, or how immune system components can affect otherorgans. You might also comment on what makes one antigen an attractive target rather thananother. Please do NOT comment on all the things listed above, they are just to get youthinking. If you are having trouble getting started, it might help to think about a specificdisease which affects multiple organs.
