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. For instance, an example of such an infection is streptococcal infections that take place, for example, in our throat. So for instance, streptococcal infections can produce antigens that have similar epitopes compared to self antigens found in our heart. This can lead to a condition an autoimmune disease known as Rheumatic heart disease.
