Background: As we discussed in class, there are several complement regulators on the surface of our cells and in our body fluids. These regulators are essential in preventing the activation of the complement cascade and eventual lysis of our self cells. In some cases, however, cells may become deficient in these regulatory proteins as a result of a random gene mutation in one of the pluripotent stem cells in the bone marrow. One such deficiency is called paroxysmal nocturnal hemoglobinuria....
