What is the Origin of Renal Fibrosis?

The term combines "renal," derived from the Latin renalis meaning "of the kidney," with "fibrosis," derived from the Latin fibra meaning fiber, referring to the abnormal accumulation of fibrous connective tissue. This pathological description is central to the understanding of chronic kidney disease progression. The underlying etiology often involves sustained injury or inflammation within the kidney.

What is the Mechanism of Renal Fibrosis?

The process is initiated by chronic injury, which triggers the activation and proliferation of interstitial fibroblasts and pericytes, transforming them into myofibroblasts. These activated myofibroblasts are the principal cells responsible for the overproduction and deposition of extracellular matrix components. Various pro-fibrotic mediators, such as Transforming Growth Factor-beta (TGF-$beta$), perpetuate this pathological cycle, leading to the progressive obliteration of the kidney's microvasculature and the eventual structural collapse of the nephrons.

Renal Fibrosis

Meaning

Renal fibrosis is a pathological process in the kidney characterized by the excessive accumulation of extracellular matrix proteins, primarily collagen, leading to the formation of scar tissue within the renal parenchyma. This progressive scarring replaces functional kidney tissue, disrupting the normal architecture and ultimately resulting in a decline in glomerular filtration rate and end-stage renal disease. It is the final common pathway for nearly all chronic kidney diseases, representing a critical target for therapeutic intervention in nephrology.
