Similarly, a study showed that higher levels of IL-2, IL-6, IL-10, TNF-α, and PGE2 were detected in the serum of preterm women with periodontal disease, while the serum levels of IL-2, IL-6, and IL-10 were higher in high-risk preterm women than in low-risk preterm women (37). Here, IL10 is linked to periodontal disorder.
