Intervertebral disc degeneration (IDD) is the leading cause of low back pain (LBP) and disability in the elderly, imposing significant public health and economic burden worldwide. Meanwhile, the pathological mechanisms of IDD remain complicated, and treatment strategy to reverse IDD is primarily due to the unclear specific mechanisms of IDD and the lack of particular effective targets. Interleukin-1β (IL-1β), one of the most important members of the IL-1 family, can induce solid pro-inflammatory activity by stimulating the secretion of various pro-inflammatory mediators and is considered the key to IDD mediator. However, in recent years, IL-1β is considered to be able to regulate IVD cell death in many ways, such as apoptosis, pyroptosis, ferroptosis, and so on. At the same time, numerous studies on IL-1β inhibitors suggest that inhibition of IL-1β may be a promising biological therapy for IDD. Many IL-1β inhibitors have been investigated through various pathogenic biological mechanisms, including inhibiting inflammatory processes, regulating ECM degradation, and more. Therefore, anti-IL-1β therapy may have the effect of alleviating disc degeneration. This article mainly reviews the mechanisms and functions of IL-1β in IDD and investigates advances in IL-1β inhibition as a promising biotherapeutic approach for disc degeneration. • The current article reviews the mechanisms and functions of IL-1β in IDD and investigates advances in IL-1β inhibition as a promising biotherapeutic approach for disc degeneration. We demonstrate function of IL-1β from different aspects, such as inflammatory responses, ECM metabolism, cell senescence, cell apoptosis, pyroptosis, and ferroptosis, oxidative stress, angiogenesis and neoinnervation in IDD. It is suitable for the audience of Experimental Gerontology, as IDD is a condition affecting the elderly. • This article could provide a valuable resource for researchers and clinicians seeking to better understand the role of IL-1β in IDD and explore potential therapeutic targets. • We provide a comprehensive review of the involvement of IL-1β in intervertebral disc degeneration (IVDD) and its potential as a therapeutic target. However, the article would benefit from a more detailed discussion on the differences between animal models and human in vivo experiments, as well as the potential limitations and challenges in translating these findings to human subjects. • We have presented several studies that show the promising effects of IL-1β inhibition in vitro and in animal models. However, the safety, reliability, and effectiveness of such treatments in humans remain uncertain. The article would benefit from a discussion of the challenges in conducting clinical trials for these treatments and the need for more extensive clinical studies in the future. • While we acknowledge the difficulty of studying intervertebral disc (IVD) tissue homeostasis, the review would benefit from a more in-depth exploration of the inflammatory process during IDD and its implications for the development of IL-1β-centered therapies. This may include a discussion of the role of inflammation in maintaining homeostasis and the potential risks of completely suppressing IL-1β-induced inflammation. • The article discusses the potential for IL-1β-centered therapy to restore homeostasis in the intervertebral disc. However, it would be beneficial for researchers and clinicians to provide more information on the current state of research in this area, including any promising drug candidates or novel approaches to treatment.
