炎症细胞因子导致根尖周组织破坏。它们的活性可能受到 SOCS(细胞因子信号传导抑制因子)的调节,SOCS 作为抑制性反馈环路的一部分下调信号转导。我们通过实时 PCR 研究了 57 例根尖周肉芽肿和 38 例健康根尖周组织中细胞因子 TNF-α、IL-10 和 RANKL 以及 SOCS-1、-2 和 -3 的表达。与健康对照相比,根尖肉芽肿表现出显着较高的 SOCS-1、-2 和 -3、TNF-α、IL-10 和 RANKL mRNA 水平。 SOCS1 和 IL-10 之间以及 SOCS3 和 IL-10 之间发现显着正相关。 SOCS1 和 TNF-α、SOCS1 和 RANKL、SOCS3 和 TNF-α 之间观察到显着的负相关。根尖肉芽肿中 SOCS-1、-2 和 -3 mRNA 水平升高可能与这些病变中炎症细胞因子的下调有关;因此,SOCS分子可能在根尖肉芽肿发展的动力学中发挥作用。
Inflammatory cytokines contribute to periapical tissue destruction. Their activity is potentially regulated by SOCS (suppressors of cytokine signaling), which downregulate signal transduction as part of an inhibitory feedback loop. We investigated the expression of the cytokines TNF-α, IL-10 and RANKL, and SOCS-1, -2 and -3 by Real Time-PCR in 57 periapical granulomas and 38 healthy periapical tissues. Periapical granulomas exhibited significant higher SOCS-1, -2 and -3, TNF-α, IL-10 and RANKL mRNA levels when compared to healthy controls. Significant positive correlations were found between SOCS1 and IL-10, and between SOCS3 and IL-10. Significant inverse correlations were observed between SOCS1 and TNF-α, SOCS1 and RANKL, and SOCS3 and TNF-α. Increased SOCS-1, -2 and -3 mRNA levels in periapical granulomas may be related to the downregulation of inflammatory cytokines in these lesions; therefore, SOCS molecules may have a role in the dynamics of periapical granulomas development.
