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
