Due to deposition of IgG antigen comple­xes in the blood vessels cause local damage and deposit in blood vessels of kidney glomeruli called Arthus Reaction. 2. TOS4. Immune system plays the most important role in understanding the diseases and also protects us from infections by different types of diffence. Although initially described for their immunomodulatory Type IV hypersensitivity requires CD4+ type. Many of the germs that affect other species don't harm us. Immune cell isolation. ADVERTISEMENTS: Three types into which the agglutination techniques of cells are classified are: 1. direct agglutination, 2. indirect (passive) agglutination and 3. reverse (passive) agglutination. Type II hypersensitive reactions are those in which tissue or cell damage is the direct result of the actions of antibody and complement. Enhancement of phagocytosis by IgG antibody which is referred to a blocking antibody because it competes for the aller­gens, binds and forms a complex that can be removed by phagocytosis. During summer 2018, I was a recipient of High School Summer Research Program award from the American Association of Immunologists. Vaccine Types 1.
