Treating patients with convalescent plasma involves obtaining blood from patients that have already survived the virus and injecting their plasma into patients currently suffering for the disease. How would treating patients with convalescent plasma potentially kill COVID-19? A Increased helper t cell mediated activation в Increased monocyte/macrophage counts Increased albumin binding D None of the answers are correct E Increased B lymphocyte activation F Increased neutrophil counts Increased IgG binding

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.

Helper T cells are affected by HIV, how come is this receptor key to the immune system? which line of defense are we referring to? How is it connected to the immune system and which line of defense? Hence, based on your prompt, how are cytokines linked to the defense mechanism of HIV virus? Do you know or can you explain the cascade of events dealing with PAMPS, TLRs, interferon? What do they have to do with the second line of defense?
