Disease Control (CDC) determine that the agent causing the birds to die is the West Nile virus. Outbreaks of this illness have been observed in several other countries in Asia and the Middle East across the last 50 years, but not in the United States. With this information, what would be the best categorization of this infectious agent/disease

#Unit 4. Cell Communication and Cell Signaling
  1. This is clearly a reemerging infection. It's been around for a long time, and it is reappearing in a susceptible population again.

  2. This is clearly a nosocomial infection. It's transmitted from animals to human beings in urban environments.

  3. This is clearly an emerging infection. It hasn't been around that long, and it has made a jump across continents into a new susceptible population.

  4. This is clearly not a concern to human beings--maybe it's emerging in animals, maybe it's reemerging, maybe it's nosomial. But who cares? It's only in birds.

When stress conditions arise, or when protein synthesis threatens to overwhelm the protein-folding capacity of the ER, unfolded proteins can accumulate. These conditions trigger the unfolded protein response (UPR)

a) unfolded protein response ensures to reduces the rate of protein synthesis by mTOR pathway

b) Amyloid aggregates that form before the UPR can come into play may be removed. Some are degraded by autophagy

c) Amyloid aggregates that can be removed by other mechanism such as lysosomal degradations

d)  UPR also bring the various systems into alignment by increasing the concentration of chaperones in the oxygen deprived conditions
