椎间盘退变(intervertebral disc degeneration,IVDD)是一种常见的脊柱疾病,其发病机制目前尚不完全清楚.炎症细胞如中性粒细胞、巨噬细胞等以及炎症趋化因子如TNF-α、IL-1β和IL-6等在退变椎间盘中可促进髓核细胞的凋亡和降解,导致IVDD.此外,炎症细胞因子也可以刺激软骨终板细胞产生一系列炎症介质,引发炎症反应.在信号通路方面,NF-κB、MAPK和PI3K/Akt等信号通路被发现在IVDD过程中发挥关键作用,调节炎症细胞因子的表达,并参与调控纤维环细胞的生存和代谢.因此,针对炎症细胞因子及其相关信号通路的干预措施可能成为治疗IVDD的新途径.综上所述,炎症细胞因子及相关信号通路在IVDD中发挥着重要作用,对其进行深入研究将有助于寻找治疗IVDD的新方法.该综述旨在探讨炎症细胞因子在IVDD中的作用及相关信号通路的调控机制,并系统总结基于炎症反应干预IVDD的措施.
The Mechanism of Inflammatory Cytokines and Its Relevant Pathways in Intervertebral Disc Degeneration
IVDD(intervertebral disc degeneration)is a common spinal disease,and its pathogenesis is cur-rently not fully understood.Inflammatory cells such as neutrophils,macrophages,and inflammatory chemokines such as TNF-α,IL-1β,and IL-6 can promote apoptosis and degradation of nucleus pulposus cells in degenerated intervertebral discs,leading to IVDD.In addition,inflammatory cytokines can also stimulate chondrocyte endplate cells to produce a series of inflammatory mediators,triggering an inflammatory response.In terms of signaling pathways,NF-κB,MAPK,and PI3K/Akt signaling pathways have been found to play key roles in the IVDD pro-cess,regulating the expression of inflammatory cytokines and participating in the regulation of the survival and metabolism of annulus fibrosus cells.Therefore,interventions targeting inflammatory cytokines and their related signaling pathways may become a new approach for treating IVDD.In summary,inflammatory cytokines and related signaling pathways play an important role in IVDD,and in-depth research on them will help to find new methods for treating IVDD.This review aims to explore the role of inflammatory cytokines in IVDD and the regu-latory mechanisms of related signaling pathways,and systematically summarize the intervention measures based on inflammatory response in IVDD.
