What role does apoptosis play in progression of renal disease?
Abstract:
Apoptosis (programmed cell death) is now recognized to play an important role in regulating the number of renal cells in health and disease. Apoptosis may mediate beneficial deletion both of leukocytes and of excess resident cells from the inflamed glomerulus. However, this review focuses on the growing evidence that inappropriate engagement of the cell death 'program' contributes to the progression of renal diseases such as polycystic kidney disease and glomerulonephritis, mediating the loss of 'desirable' cells and eventual development of the hypocellular end-stage kidney.
Insights
Apoptosis, or programmed cell death, regulates renal cell numbers. Dysfunctional apoptosis contributes to kidney disease progression, causing cell loss and end-stage renal disease.
Area of Science:
- Nephrology
- Cell Biology
- Pathology
Background:
- Apoptosis (programmed cell death) is crucial for regulating renal cell populations in both healthy and diseased kidneys.
- It can facilitate beneficial removal of excess cells and leukocytes in inflamed glomeruli.
Purpose of the Study:
- To review the role of apoptosis in renal disease progression.
- To highlight how inappropriate apoptosis contributes to kidney pathology.
Main Methods:
- Literature review of studies on apoptosis in renal diseases.
- Analysis of evidence linking cell death pathways to kidney conditions.
Main Results:
- Apoptosis plays a dual role: beneficial in inflammation and detrimental when dysregulated.
- Inappropriate apoptosis contributes to the loss of functional renal cells.
Conclusions:
- Dysregulated apoptosis is a key factor in the progression of renal diseases like polycystic kidney disease and glomerulonephritis.
- This aberrant cell death leads to hypocellularity and end-stage renal disease.
