Decline is not inevitable.

A daily, evidence-graded view of everything moving in kidney research : the drugs that slow decline, the science of regeneration, and the mind-body work.

New research identifies a self-perpetuating loop that drives kidney scarring

Key takeaways

A large study found a self-perpetuating loop of damage that drives kidney scarring. Hypertension is also a major risk factor for kidney disease. Loneliness and social isolation are linked to lower life expectancy without mental disorder.

A self-sustaining hypoxia inducible factor-1α–creatine kinase B feedforward circuit drives macrophage-mediated kidney fibrosis

This study found that kidney scarring (fibrosis) is driven by a self-perpetuating loop of cell damage. This loop involves the protein HIF and differs from other types of kidney scarring. It's a large-scale study with many patients, but it focuses on the mechanism of scarring rather than direct treatment outcomes.
