The Gut Microbiome, Inflammation, and Salt-Sensitive Hypertension.
Study Goal
The researchers aimed to investigate the role of salt sensitivity in blood pressure and its link to cardiovascular events, focusing on immune system involvement and gut-related mechanisms.
Results Summary
The study found that high-salt diets increase inflammation, dendritic cell production of IL-6, and formation of IsoLG-protein adducts, driving T-cell production of IFN-γ and IL-17A, contributing to salt-induced hypertension. The gut was identified as a key site for sodium interaction.

PURPOSE OF REVIEW: Salt sensitivity of blood pressure (SSBP) is an independent predictor of death due to cardiovascular events and affects nearly 50% of the hypertensive and 25% of the normotensive population. Strong evidence indicates that reducing sodium (Na RECENT FINDINGS: The innate and adaptive immune systems are involved in the genesis of salt-induced hypertension. Mice fed a high-salt diet exhibit increased inflammation with a marked increase in dendritic cell (DC) production of interleukin (IL)-6 and formation of isolevuglandins (IsoLG)-protein adducts, which drive interferon-gamma (IFN-γ) and IL-17A production by T cells. While prior studies have mainly focused on the brain, kidney, and vasculature as playing a role in salt-induced hypertension, the gut is the first and largest location for Na
