Thymosin \u03b24 (T\u03b24) is a 43 amino acid multifunctional polypeptide that is involved in wound healing. Prolyl oligopeptidase (POP) is the main enzyme that hydrolyzes T\u03b24 to produce its derivative N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) which is found to play a role in the regulation of fibrosis. Accumulating evidence suggests that the T\u03b24-POP-Ac-SDKP axis widely exists in various tissues and organs including the liver, kidney, heart, and lung, and participates in the process of fibrogenesis. Herein, we aim to elucidate the role of T\u03b24-POP-Ac-SDKP axis in hepatic fibrosis, renal fibrosis, cardiac fibrosis, and pulmonary fibrosis, as well as the underlying mechanisms. Based on this, we attempted to provide novel therapeutic strategies for the regulation of tissue damage repair and anti-fibrosis therapy. The T\u03b24-POP-Ac-SDKP axis exerts protective effects against organ fibrosis. It is promising that appropriate dosing regimens that rely on this axis could serve as a new therapeutic strategy for alleviating organ fibrosis in the early and late stages.<\/jats:p>","DOI":"10.3390\/ijms232113282","type":"journal-article","created":{"date-parts":[[2022,11,1]],"date-time":"2022-11-01T06:01:28Z","timestamp":1667282488000},"page":"13282","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Role of T\u03b24-POP-Ac-SDKP Axis in Organ Fibrosis"],"prefix":"10.3390","volume":"23","author":[{"given":"Wei","family":"Wang","sequence":"first","affiliation":[{"name":"Queen Mary School, Nanchang University, Nanchang 330006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenning","family":"Jia","sequence":"additional","affiliation":[{"name":"Queen Mary School, Nanchang University, Nanchang 330006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0159-4547","authenticated-orcid":false,"given":"Chunping","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Cell Biology, College of Medicine, Nanchang University, Nanchang 330006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1162","DOI":"10.1073\/pnas.78.2.1162","article-title":"Complete amino acid sequence of bovine thymosin beta 4: A thymic hormone that induces terminal deoxynucleotidyl transferase activity in thymocyte populations","volume":"78","author":"Low","year":"1981","journal-title":"Proc.
