GIMAP6-focused research exploring how loss of an immune gene might drive artery disease through immune‑cell dysfunction, with implications for risk biology.
Key Takeaways
- Mice lacking GIMAP6 developed atherosclerosis, heart attacks, heart failure, and early death despite normal blood cholesterol.
- Mechanistic data show GIMAP6 loss raised mitochondrial oxidative stress, upregulated PPARγ and CD36, and accelerated macrophage foam cell formation.
- Human carriers of a weaker GIMAP6 variant, more common in African ancestry, had monocytes with lower GIMAP6, higher CD36, and increased fat uptake.
