Good and evil, more reasons to study UPR.

Abstract

The unfolded protein response (UPR) pathway, launched by endoplasmic reticulum, maintains endoplasmic reticulum homeostasis. Dysregulated UPR pathway links disease phenotypes, such as proteinuria, inflammation, and fibrosis, in kidney disease. Although accumulating evidence indicates the beneficial impact of the UPR pathway as a therapeutic target for various diseases, including kidney disease, the control of adaptive UPR status is still difficult for disease treatment. This article may give us a new insight into the strategy for sustaining the kidney protective UPR pathway.
