The actual therapeutic regimen to treat Mab infections is based on repurposed drugs from therapies against Mycobacterium tuberculosis and avium. In addition to the need for new specific drugs against this bacterium, a possible strategy for shortening the therapeutic time and improving the success rate could be targeting Mab virulence factors. These drugs could become an important integration to the actual therapeutic regimen, helping the immune system to fight the infection. Moreover, this strategy applies a low selective pressure on the bacteria, since these elements are not essential for Mab survival but crucial for establishing the infection. This review aims to provide an overview of the Mab\u2019s virulence factors that are poorly studied and mostly unknown, suggesting some interesting alternatives to classical drug development.<\/jats:p>","DOI":"10.3390\/ijms26073247","type":"journal-article","created":{"date-parts":[[2025,4,1]],"date-time":"2025-04-01T07:00:45Z","timestamp":1743490845000},"page":"3247","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Mycobacterium abscessus Virulence Factors: An Overview of Un-Explored Therapeutic Options"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7074-0328","authenticated-orcid":false,"given":"Mario","family":"Cocorullo","sequence":"first","affiliation":[{"name":"Department of Biology and Biotechnology \u201cLazzaro Spallanzani\u201d, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7065-1501","authenticated-orcid":false,"given":"Alessandro","family":"Stamilla","sequence":"additional","affiliation":[{"name":"Department of Biology and Biotechnology \u201cLazzaro Spallanzani\u201d, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2735-5165","authenticated-orcid":false,"given":"Deborah","family":"Recchia","sequence":"additional","affiliation":[{"name":"Department of Biology and Biotechnology \u201cLazzaro Spallanzani\u201d, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-9425-1569","authenticated-orcid":false,"given":"Maria Concetta","family":"Marturano","sequence":"additional","affiliation":[{"name":"Department of Biology and Biotechnology \u201cLazzaro Spallanzani\u201d, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ludovica","family":"Maci","sequence":"additional","affiliation":[{"name":"Department of Biology and Biotechnology \u201cLazzaro Spallanzani\u201d, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5219-4770","authenticated-orcid":false,"given":"Giovanni","family":"Stelitano","sequence":"additional","affiliation":[{"name":"Department of Biology and Biotechnology \u201cLazzaro Spallanzani\u201d, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pereira, A.C., Ramos, B., Reis, A.C., and Cunha, M.V.
