Its early-stage lesions are insidious and lack reliable biomarkers, and the current diagnosis relies on imaging. Piezo1, a mechanosensitive ion channel widely expressed by intervertebral disc cells, is a core molecule that senses mechanical signals. As a core load-bearing structure of the spine, the mechanical responsiveness of the intervertebral disc is critical for homeostasis, and abnormal mechanical loading is a key trigger of LDD. Piezo1 is deeply involved in the pathology of LDD by sensing abnormal stress and mediating Ca\n                    <jats:sup>2+<\/jats:sup>\n                    influx. On the one hand, activation of the Piezo1-Ca\n                    <jats:sup>2+<\/jats:sup>\n                    axis triggers inflammatory pathways such as NF-\u03baB and the upregulation of proinflammatory factors and matrix-degrading enzymes (e.g., MMPs, ADAMTS); on the other hand, it inhibits the synthesis of the extracellular matrix (ECM), such as type II collagen and proteoglycans, and promotes apoptosis and senescence. The \u201chypersensitive state\u201d of degenerated discs, in which Piezo1 expression and activity are significantly elevated, is the core link between the transduction and amplification of mechanical signals and pathological cascades. By systematically reviewing the structure and function of Piezo1 and its regulatory mechanism in LDD, we aimed to clarify its role as a core mechanosensing molecule in degeneration and provide theoretical basis for new prevention and treatment strategies.\n                  <\/jats:p>","DOI":"10.3389\/fcell.2026.1679466","type":"journal-article","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T06:38:36Z","timestamp":1770964716000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Etiology, diagnosis and treatment of lumbar disc degeneration: a focus on the mechanism of action of Piezo1 and research perspectives"],"prefix":"10.3389","volume":"14","author":[{"given":"Yan","family":"Gong","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Suzhou TCM Hospital Affiliated with Nanjing University of Chinese Medicine","place":["Suzhou, China"]},{"name":"Nanjing University of Chinese Medicine","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaojun","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Spinal Surgery, Second Affiliated Hospital of Guangzhou Medical University","place":["Guangzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahui","family":"He","sequence":"additional","affiliation":[{"name":"Department of Orthopedics Surgery, The Affiliated TCM Hospital of Guangzhou Medical University","place":["Guangzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanchi","family":"Gan","sequence":"additional","affiliation":[{"name":"Department of Orthopedics Surgery, Ruikang Hospital Affiliated with Guangxi University of Chinese Medicine","place":["Nanning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaobing","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Spinal Surgery, Second Affiliated Hospital of Guangzhou Medical University","place":["Guangzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jintao","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Suzhou TCM Hospital Affiliated with Nanjing University of Chinese Medicine","place":["Suzhou, China"]},{"name":"Nanjing University of Chinese Medicine","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"568","DOI":"10.1097\/01.BRS.0000101422.36419.D8","article-title":"Effect of nicotine on spinal disc cells: a cellular mechanism for disc degeneration:","volume":"29","author":"Akmal","year":"2004","journal-title":"Spine"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1884","DOI":"10.1038\/ncomms2899","article-title":"Dehydrated hereditary stomatocytosis linked to gain-of-function mutations in mechanically activated PIEZO1 ion channels","volume":"4","author":"Albuisson","year":"2013","journal-title":"Nat.
