Kidney Vesicles Carrying Toxic miRNA Linked to Heart Damage in Chronic Kidney Disease

Peer-reviewed findings suggest biomarker pathways for risk stratification, with EV-targeting approaches still at a preclinical stage.

Overview

  • Researchers at UVA Health and Mount Sinai report that kidney-derived circulating extracellular vesicles in CKD carry miRNA that is toxic to heart tissue.
  • In mouse models, blocking these vesicles improved cardiac function and reduced signs of heart failure.
  • Analyses of human plasma found harmful extracellular vesicles in patients with chronic kidney disease but not in healthy volunteers.
  • The team says the results could enable blood tests to identify high-risk patients and therapies designed to neutralize or block pathogenic vesicles, pending further validation.
  • The study, published in Circulation (Li et al., 2026), notes CKD affects about 35 million Americans and is common in people with diabetes or hypertension.
