Bayer – Evasion & Subversion of Immune Defenses (A) Provide five examples that compare and contrast the immune response to extracellular bacteria, intracellular bacteria, and viruses. (5 points) (B) Pathogens employ strategies to evade or interfere with the host’s immune response, ultimately allowing them to establish and persist within the host. Briefly define three strategies that pathogens employ to evade the immune system. (3 points) (C) Briefly describe an effective treatment strategy to stimulate a person’s immune system to produce strong immunity against a latent viral infection. (8 points) The immune response within the tumor microenvironment resembles either tumor elimination or tumor escape. (D) In the elimination microenvironment, briefly define an immune cell type, their mode-of-action, and how the tumor itself plays a role in immune recognition. (3 points) (E) In the escape microenvironment, briefly define an immune cell type, their mode-of-action and how the tumor itself plays a role in avoiding immune recognition. (3 points)
