In the atherosclerosis + vector group, serum levels of TNF-α (Figure 3(a)) and IL-1β (Figure 3(b)) significantly increased (P < 0.01), whereas the serum level of TGF-β1 (Figure 3(c)) significantly decreased (P < 0.05), as compared with the control group. This evidence concerns the gene TGFB1 and atherosclerosis.
