The primary pathological hallmark is progressive degeneration, predominantly affecting sensory and motor neurons, leading to prominent sensory deficits and progressive motor impairments. While neuropathy-causing mutations in the ubiquitously expressed small heat shock protein HSPB1 account for a subset of axonal CMT cases, the mechanisms underlying the selective vulnerability of peripheral neurons remain poorly understood. In this review, we synthesize emerging evidence to reframe HSPB1-related CMT as a prototypical gene\u2013environment interaction disorder. The unique anatomical exposure and high metabolic demands of the peripheral nervous system (PNS) render it particularly vulnerable to HSPB1 mutation-mediated homeostatic collapse, which manifests through three interconnected pathological axes: proteostatic disturbance, cytoskeletal dysregulation, and mitochondrial dysfunction. Crucially, these deficits converge to impair the stress adaptability of peripheral neurons, creating a maladaptive feedback loop wherein environmental stressors exacerbate intrinsic vulnerabilities. We further propose a phase-specific therapeutic framework that prioritizes early intervention during the clinically silent yet biologically active prodromal stage, when targeted modulation of the HSPB1 chaperone interactome and remodeling neural homeostasis may forestall neurodegeneration. This therapeutic paradigm shift from symptomatic management to preclinical neuroprotection underscores the imperative for precision medicine approaches in future CMT intervention.<\/jats:p>","DOI":"10.3390\/cells15030271","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T12:49:44Z","timestamp":1770036584000},"page":"271","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Stress-Driven Selective Neuronal Vulnerability in Charcot\u2013Marie\u2013Tooth Disease: From Prodromal Pathology to Therapeutic Implications"],"prefix":"10.3390","volume":"15","author":[{"given":"Xianchao","family":"Pan","sequence":"first","affiliation":[{"name":"Functional Experiment Center, School of Basic Medical Science, Bengbu Medical University, Bengbu 233030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiming","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Basic Medical Science, Southwest Medical University, Luzhou 646000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyu","family":"Li","sequence":"additional","affiliation":[{"name":"School of Basic Medical Science, Southwest Medical University, Luzhou 646000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuemeng","family":"Xiang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Southwest Medical University, Luzhou 646000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongzhen","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Southwest Medical University, Luzhou 646000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qianqian","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Southwest Medical University, Luzhou 646000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haidong","family":"Xu","sequence":"additional","affiliation":[{"name":"Functional Experiment Center, School of Basic Medical Science, Bengbu Medical University, Bengbu 233030, China"},{"name":"Department of Pathophysiology, School of Basic Medical Science, Bengbu Medical University, Bengbu 233030, China"},{"name":"Key Laboratory of Basic and Clinical Cardiovascular Diseases, Bengbu Medical University, Bengbu 233030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5909-2892","authenticated-orcid":false,"given":"Ying","family":"Wan","sequence":"additional","affiliation":[{"name":"School of Basic Medical Science, Southwest Medical University, Luzhou 646000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Xing","sequence":"additional","affiliation":[{"name":"School of Basic Medical Science, Southwest Medical University, Luzhou 646000, China"},{"name":"Department of Pathophysiology, School of Basic Medical Science, Bengbu Medical University, Bengbu 233030, China"},{"name":"Key Laboratory of Basic and Clinical Cardiovascular Diseases, Bengbu Medical University, Bengbu 233030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1111\/j.1529-8027.2011.00324.x","article-title":"Charcot-Marie-Tooth disease","volume":"16","author":"Reilly","year":"2011","journal-title":"J.
