Cmpd17b Lowers Blood Pressure at 50 mg/kg and Reverses Kidney Fibrosis in Hypertensive Mice

1 articles · Updated · Nature.com · Aug 13

Summary

  • 28 days of Cmpd17b treatment selectively lowered blood pressure in BPH/2 J hypertensive mice, while leaving blood-pressure-normal mice largely unaffected.
  • At 50 mg/kg/day, the FPR agonist also improved aortic distensibility and cut collagen deposition across organs, with the strongest anti-fibrotic effect seen in the kidney.
  • RNA sequencing linked that kidney response to abnormal Serpina1e and Igfbp2 upregulation in hypertensive mice, which Cmpd17b normalized.
  • The findings position FPR agonism as a potential therapy for established essential hypertension by targeting both pressure control and renovascular remodeling, not just preventing damage.

Insights

Why does this experimental compound selectively lower blood pressure in diseased subjects while leaving healthy ones completely unaffected?
Could an immune receptor meant to detect bacteria hold the secret to reversing kidney damage in severe hypertension?
