Complement activation is a cascade reaction, with each component sequentiallyacting on others, in a similar way to the blood-clotting system. Discuss the effectsthat occur when peptides are generated from the activation by either the classicalor the alternative pathway. This is an immunology question
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.
