Summary
Endoplasmic reticulum (ER) stress, caused by unfolded protein accumulation, triggers the unfolded protein response (UPR). This review explores ER stress in kidney disease and potential therapies.
Area of Science:
- Cellular biology
- Nephrology
- Pathophysiology
Background:
- Endoplasmic reticulum (ER) stress arises from unfolded protein accumulation, impacting cellular function.
- Cells activate the unfolded protein response (UPR) to manage ER stress, influencing survival or cell death.
- ER stress is increasingly recognized in the development of acute and chronic kidney diseases.
Purpose of the Study:
- To review the current understanding of ER stress in renal disease.
- To highlight recent advancements in the field.
- To discuss potential therapeutic strategies targeting ER stress in kidney disease.
Main Methods:
- Literature review of studies on ER stress and kidney disease.
- Synthesis of current knowledge on UPR pathways in renal pathophysiology.
- Analysis of emerging therapeutic targets for ER stress.
Main Results:
- ER stress plays a significant role in the pathophysiology of various kidney conditions.
- The UPR can be adaptive or lead to cell death depending on the severity and duration of ER stress.
- Recent research has identified specific molecular mechanisms linking ER stress to kidney damage.
Conclusions:
- ER stress is a critical factor in kidney disease progression.
- Targeting ER stress pathways offers promising therapeutic avenues for renal diseases.
- Further research is needed to fully elucidate the therapeutic potential of modulating ER stress.

01:17Role of ER in the Secretory Pathway
Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

01:20Renal Corpuscle
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

01:28Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
01:37The Unfolded Protein Response
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
01:21Smooth Endoplasmic Reticulum
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

01:10Nephrons
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma happens...
