This article reviews the physiological and pathological roles of TDP-43, its potential as a biomarker, and its candidacy as a therapeutic target. Challenges in detecting pathological forms of TDP-43 in biofluids hinder diagnostic advancements, yet recent research provides insights into its potential diagnostic and prognostic value. Moreover, ongoing efforts aim to develop targeted therapies, including genetic and proteostasis-based approaches, to mitigate TDP-43 pathology and its downstream effects. The article also discusses the need for novel animal models and antibodies to distinguish between pathological and physiological forms of TDP-43 for reliable biomarker development. Looking ahead, the article advocates for both linear and horizontal developments in TDP-43 research to advance ALS diagnosis, prognosis, and treatment paradigms.</div></div>","PeriodicalId":72129,"journal":{"name":"Aging and health research","volume":"5 1","pages":"Article 100215"},"PeriodicalIF":0.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
