For each scenario below, choose the most appropriate answer from the list above. Each option may be used once, more than once or not at all.

1. Produced by macrophages when infected by mycobacteria to stimulate T-cells to secrete gIFN, essential for activation of oxidative killing.

2. If mutated, antibody class-switching fails. As a result, IgM levels are increased but IgG and IgA are undetectable.

3. Expressed on the activated endothelium in order to allow phagocytes to be recruited and attach to the vessel wall.

4. Binds to lipopolysaccharides on the cell wall of Gram negative bacteria to activate the alternative complement pathway.

5. The first antibody to be produced in response to an infection; levels rise within the first two weeks.
