Heart HealthGIMAP6 Protects Arteries Against Damage Beyond High Cholesterol in Mice
High cholesterol is not the only route to dangerous artery disease. Researchers found that mice missing the immune gene GIMAP6 developed damaged blood vessels, rapidly worsening artery plaques, heart attacks, and fatal heart failure without elevated blood lipids. Gene loss weakened the vessel lining and increased fat uptake by immune cells, helping them become overloaded with fat and promoting inflammation. In humans, reduced-function versions of GIMAP6 were associated with altered immune cell chemistry, greater fat uptake, and early cardiovascular disease. These findings identify a possible protective pathway that deserves further study, not a treatment ready for patients. They do not change the importance of managing cholesterol and other established heart risks. This summary relies on the abstract only; study sizes and detailed methods were not available.
