Pattern Recognition Receptors (PRRs) are crucial components of the innate immune system, enabling immune cells to detect pathogens and initiate an immune response. (A)  Identify and describe one type of PRR that plays a critical role in sensing viral infections and propose a strategy to enhance this PRR-mediated immune responses. Justify your approach based on known PRR signaling mechanisms. (4 points) (B)  Propose a strategy to enhance PRR-mediated immune responses against viral infections. Design an experiment, assuming unlimited resources, to test the efficacy of your strategy. Briefly describe your methodology, controls, and expected results. (5 points)

When using wire rope or cable from a winch, rescuers must:

When establishing a perimeter around a fire scene, the perimeter must be:

What do manufacturers sometimes add to stored-pressure water extinguishers in order to increase their effectiveness?

If foreign objects that can damage fibers are found in a rope during inspection, the rope:

Synthetic fiber rope:

A portable fire extinguisher must be labeled with the:

On which type of fires are stored-pressure water mist extinguishers safe and effective to use?

Epithelial cells serve as a frontline defense in innate immunity by forming physical barriers and producing soluble mediators that influence immune responses. (A)  Propose one strategy to enhance epithelial cell-mediated innate immunity against a respiratory bacterial infection. Justify your approach based on known epithelial innate immune functions. (3 points) (B)  Design an experiment, assuming unlimited resources, to test the efficacy of your strategy from Part A. Briefly describe your methodology, controls, and expected results. (5 points)
