Researchers identify new inflammatory mechanism for high blood pressure

Researchers from Australia and Singapore have identified a potential third mechanism behind high blood pressure: the failure of natural biological processes to resolve inflammation. While medical science has traditionally focused on the sympathetic nervous system and the renin-angiotensin-aldosterone hormone system, new findings suggest that chronic inflammation—where the immune system remains overactive—plays a critical role in hypertension.

In laboratory tests, an experimental compound labeled ‘17b’ was used to target formyl-peptide receptors, which act as molecular switches to signal immune cells to conclude their defensive response. Unlike traditional anti-inflammatory drugs that can suppress the immune system and potentially raise blood pressure, the 17b compound aims to ‘awaken’ the body’s natural pathways for stopping inflammatory overreactions.

Studies conducted on mice showed that the compound not only lowered blood pressure but also reduced arterial stiffness and minimized scarring in the heart and kidneys. Researchers noted that activating these receptors could serve as a promising therapeutic strategy for reducing blood pressure and potentially reversing fibrosis associated with kidney disease.
