It was reported that (i) the MMP activity within the atherosclerotic lesions of animals was impacted by the deletion of IFN‐γ on CD8+ T cells in a murine abdominal aortic aneurysm model, and (ii) this effect was restored by treatment with either recombinant IFN‐γ‐ or IFN‐γ+/+‐producing CD8+ T cells [46]. Here, IFNG is linked to abdominal aortic aneurysm.
