Pancreatic acinar cells (PACs) continuously produce more protein than any other cell type in the human body. As a result, PACs and other specialized secretory cells have a constant demand placed on their protein synthetic and packaging machinery. When demand for secreted products exceeds the capacity of the cell's basal protein production facilities, dangerous accumulations of misfolded proteins can build up, resulting in a condition known as ER stress. To ameliorate this stress, secretory cells activate a coordinated, three-part compensatory network collectively known as the unfolded protein response (UPR) to both expand the capacity of the ER and directly assist …
