In line with these findings we found that our animals from the atherosclerosis study showed higher levels of three Th1 cytokines (i.e. TNF, IL-12 and IFNγ) as compared to mice from the aneurysm study, while three Th2 cytokines (i.e. IL-4, IL-10 and IL-13) were not different between the two experiments (data not shown). The gene discussed is IFNG; the disease is atherosclerosis.
