ANSWER ALL QUESTIONS COMPLETELY AND CORRECTLY!!
1. After neutrophils and macrophages have engulfed pathogens into a phagosome, they still need to kill or deactivate the pathogen and any toxins they might possess.
Describe 3 categories of moleculesand their activitiesthat help phagocytic cells to do this within the cell. List these chronologically if you can.
2. In a flow chart, drawand labelall the innate components needed for initiating the classical pathway of complement activation and forming its C3 convertase. For extra credit: Include all the downstream components that are activated through to the membrane attack complex and briefly(just a few words) describe what they do to help protect the body from infection.

1.One group of immune deficiency diseases is caused by an inability of CD8 effector T cells to kill virus-infected target cells, due to defects in cytotoxic vesicle exocytosis. Because of the inflammatory response that accompanies a normal virus infection, together with the prolongation of this response due to the inability to control the infection, patients with these disorders suffer from tissue damage caused by the infiltration of effector CD8 cells and activated macrophages into multiple organs. In addition, a subset...
