Identify the tissue that is represented in the figure.

The structures of IgM and IgA contain a component that no other antibodies contain.  This structural component provides for specific binding to a receptor.  Please label your answers (1-4). 1. What is the structural component? 2. What is the receptor that can be bound by the antibodies due to the structural component, above? 3. Binding to this receptor facilitates what to be done with these antibodies (something that is not done to any other antibodies)? 4. In what tissue is this receptor most commonly found?

For each of the T cells shown below: a) indicate one cytokine (not IL-2) that is produced by the fully differentiated cell as part of its normal function, and b) indicate what the target cell for that cytokine is likely to be (what cell will be regulated by that cytokine?).    Th1 Th2 Th17 T Reg CTL

Your goal is to prevent the development of a successful immune response against Mycobacterium tuberculosis in an experimental mouse model. To do so, you will inject your mice intravenously with an anti-cytokine monoclonal antibody on the same day that you infect your mice with the pathogen. What is the cytokine specificity of this antibody?  There may be more than one correct answer.   Explain your reasoning.
