In this study, we introduce a luciferase reporter system as a new and reliable assay to measure cell damage and validate it with the pathogenic yeast,\n              <jats:italic>Candida albicans<\/jats:italic>\n              , as a test case. We transduced human epithelial cell lines with a lentiviral vector to stably express an optimized luciferase enzyme, Nanoluc. Upon cell damage, the release of cytoplasmic luciferase into the extracellular space can be easily detected by a luminometer. We used the luciferase reporter system to investigate the damage caused by\n              <jats:italic>C. albicans<\/jats:italic>\n              to different newly generated epithelial reporter cell lines. We found that fungus-induced cell damage, as determined by established methods, correlated tightly with the release of the luciferase. The new luciferase reporter system is a simple, sensitive, robust, and inexpensive method for measuring host cell damage and has a sensitivity comparable to the standard assay, release of lactate dehydrogenase. It is suitable for high-throughput studies of pathogenesis mechanisms of any microbe, for antimicrobial drug screening, and many other applications.\n            <\/jats:p>\n            <jats:sec>\n              <jats:title>IMPORTANCE<\/jats:title>\n              <jats:p>\n                We present a quick, easy, inexpensive, and reliable assay to measure damage to mammalian cells. To this end, we created reporter cell lines which artificially express luciferase, an enzyme that can be easily detected in the supernatant when these cells are damaged. We used infections with the well-investigated fungal pathogen of humans,\n                <jats:italic>Candida albicans<\/jats:italic>\n                , as a test case of our system. Using our reporter, we were able to recapitulate the known effects of strain variability, gene deletions, and antifungal treatments on host cell damage. This easily adaptable reporter system can be used to screen for damage in infection models with different microbial species, assay cell-damaging potential of substances, discover new non-toxic antibiotics, and many other damage-based applications.\n              <\/jats:p>\n            <\/jats:sec>\n          <\/jats:sec>","DOI":"10.1128\/msphere.00509-24","type":"journal-article","created":{"date-parts":[[2024,10,16]],"date-time":"2024-10-16T13:01:33Z","timestamp":1729083693000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":3,"title":["Shining a light on\n            <i>Candida<\/i>\n            -induced epithelial damage with a luciferase reporter"],"prefix":"10.1128","volume":"9","author":[{"given":"Millen","family":"Tesfamariam","sequence":"first","affiliation":[{"name":"Department of Molecular Pathogenicity Mechanisms, Leibniz Institute for Natural Product Research and Infection Biology-Hans Knoell Institute, Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5812-0484","authenticated-orcid":false,"given":"Raghav","family":"Vij","sequence":"additional","affiliation":[{"name":"Department of Molecular Pathogenicity Mechanisms, Leibniz Institute for Natural Product Research and Infection Biology-Hans Knoell Institute, Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Verena","family":"Tr\u00fcmper","sequence":"additional","affiliation":[{"name":"Department of Molecular Pathogenicity Mechanisms, Leibniz Institute for Natural Product Research and Infection Biology-Hans Knoell Institute, Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6028-0425","authenticated-orcid":true,"given":"Bernhard","family":"Hube","sequence":"additional","affiliation":[{"name":"Department of Molecular Pathogenicity Mechanisms, Leibniz Institute for Natural Product Research and Infection Biology-Hans Knoell Institute, Jena, Germany"},{"name":"Institute of Microbiology, Friedrich Schiller University, Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7740-4570","authenticated-orcid":true,"given":"Sascha","family":"Brunke","sequence":"additional","affiliation":[{"name":"Department of Molecular Pathogenicity Mechanisms, Leibniz Institute for Natural Product Research and Infection Biology-Hans Knoell Institute, Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1517\/17460441.3.6.655"},{"key":"e_1_3_3_3_2","volume-title":"Assay guidance manual","author":"Riss T","year":"2019","unstructured":"Riss T, Niles A, Moravec R, Karassina N, Vidugiriene J. 2019.
