In short, the answer is yes, there is a gene-environment interaction that increases risk for hypertension. My colleague Dr Leticia Tavares has done more work in this area doi.org/10.1101/2024...
Rare pathogenic variants in G-protein coupled receptor genes involved in gut-to-host communication are associated with cardiovascular disease risk
Background: Gut microbial metabolites called short-chain fatty acids (SCFA) confer protective effects against cardiovascular disease and high blood pressure. Proposed mechanisms include anti-inflammat...

Mechanistic studies were performed in an animal model, so we asked ourselves whether these receptors are relevant to human hypertension

Immune cells and the inflammation are linked to hypertension but direct targeting of immune cells has not been particularly effective. Perhaps we could target these receptors to reduce immune activation instead?
January 30, 2025 at 3:59 AM
We show that absence of these receptors leads to higher gut permeability (aka leaky gut) associated with higher inflammation in target organ such as the kidney. We also show that the absence of these receptors in immune cells was sufficient to worsen hypertension.

We and others have previously shown that SCFA supplementation can reduce BP but underlying mechanisms were unclear. Here we show that SCFA-receptors are protective in hypertension in the Ang II model.
