Now, in some cases the pathogenic antigen that is displayed on our membrane that came from that pathogen might resemble some other self antigen that is found on healthy cells of our body. So we have two healthy cells in some place in our body. And notice that these green cell antigens which are normally seen by the white blood cells as normal resemble the pathogenic antigen. Now, when our adaptive immune system begins producing plasma cells and these plasma cells begin to produce these antibodies that can bind to this pathogenic antigen these antibodies will not only bind to the pathogenic antigen but because of the resemblance between these two antigens our antigen and self antigen. These antibodies will also begin to bind on the self antigens of our normal, healthy cells. And once that binding takes place these antibodies will essentially label these healthy cells for destruction by our wide blood cells.
