炎性因子IL-1β、TNF-α与椎间盘退变关系的研究进展

Relationship between inflammatory cytokines of IL-1β and TNF-α and intervertebral disc degeneration

IL-1β与TNF-α炎性因子作为椎间盘退变过程中的重要参与者日益受到国内外学者的关注。在椎间盘退变并最终导致下腰痛及神经根性症状全过程中,炎性因子从中起到重要的作用。在机械创伤、过度负荷、基因易感及感染等因素的作用下,纤维环及髓核细胞合成TNF-α、IL-1β。这些炎性因子在椎间盘退变过程中的作用大致可分为3个阶段。目前关于炎性因子在椎间盘退变病理生理过程中确切的调控机制仍需进一步研究,重点将在于阐述炎性因子在椎间盘退变中的调控机制、椎间盘退变的分子靶向治疗、细胞信号通路干预及寻找抗炎治疗的最佳时机上,为其将来的临床应用提供依据。

The inflammatory cytokines of IL-1β and TNF-α participate in the process of intervertebral disc degeneration is focused by the spine surgeons. Inflammatory cytokines represented by IL-1β and TNF-α act as the key factors in the process of intervertebral disc degeneration resulting in low back pain and radicular symptoms. Annulus fibrosus and nucleus pulposus can secrete TNF-α and IL-1β under the stimulation of mechanical injury,overstressed, genetic susceptibility and infection. The mechanism of inflammatory cytokines in intervertebral disc degeneration needs further investigation. The emphasis of research- es will be on the inflammatory cytokines in the regulation of mechanism in the intervertebral disc degeneration, molecular tar- geted therapy, cell signaling pathways and the best time of anti-inflammatory therapy providing more evidence in the clinical aoDlication.
