Question

1. Use graph to represent difference between NK cells vs B, T cells and NK cells vs Macrophage/ Neutrophils.

2. Use a drawing to show positive feedback regulation NK cells contribute during infection, the drawing needs to meet the following requirements:

1) Identify cytokines NK cells respond to and produce

2) Identify immune cells that responds to cytokines produced by NK cells

3) Show ligand/receptor interaction of these cytokines

3. Identify the mechanism of how NK cells eliminate harmful cells derived from our own cells but not our normal healthy cells?

- How does our own cells become harmful?

- Show a drawing differentiating damaged self-cell vs normal cell

- Identify two different types of receptors that NK cells have to regulate activation

4. Use a mind map (words/phases connected by arrows to show connections) to demonstrate extrinsic factors that cause sepsis, the intrinsic factors involved in sepsis, and the effects sepsis has on host physiology (bodily functions).

- Define sepsis

- What is the main cause of sepsis

- How is inflammation controlled positively and negatively?

- Propose an experiment to inhibit overactivation of innate immune cell. Demonstrate the effect of your proposed treatment using a graph.
