The immune response to any virus is similar to the one you've mapped out in your flow chart. HIV is an infection that targets and kills helper T cells. Explain why HIV leads to AIDS, or acquired immunodeficiency syndrome, where the immune system is non-functional. Be sure you discuss APCs, helper T cells, cytotoxic T cells and B cells in your answer.

One of the major hallmarks of the adaptive immune response is the specificity in activating only those appropriate T and B cells to respond to the pathogen/antigen. Please discuss how the “3 cell model” of APC, T cell, and B cell ensure and maintain the specificity so that only antigen-specific cells are activated.

If your tonsils are removed, how does your body develop an immune response against antigens in the throat? The radical mastectomy is an operation in which a cancerous breast, surrounding tissues, and the underlying muscles of the anterior thoracic wall, plus the axillary lymph nodes, are removed. After such an operation, the arm usually swells, or becomes edematous, and is very uncomfortable -- sometimes for months. Why?

Some bacteria produce multiple toxins that interfere with the host’s immune response. For example, one bacterial toxin is a protease that cleaves the proteins that form tight junctions between skin cells. The result is severe, widespread blistering (patches of skin sort of peel away from the body). (a) Explain how this toxin helps the pathogen. (b) What branch of the immune system can best defend against this toxin?

Assume that there is no deterrent for the spread of the virus. (a) Set up an appropriate modelling function to determine the number of infected individuals t days after the outbreak. (b) Determine how many individuals will be infected 10 days after the outbreak. (c) Determine how long it will take...
