Further mechanistic observations suggested that the enhanced antifungal activity may involve facilitated drug uptake and suppression of efflux function, alongside reduced expression of adhesion-related genes (\n                      <jats:italic toggle=\"yes\">ALS1<\/jats:italic>\n                      ,\n                      <jats:italic toggle=\"yes\">ALS3<\/jats:italic>\n                      ,\n                      <jats:italic toggle=\"yes\">HWP1<\/jats:italic>\n                      , and\n                      <jats:italic toggle=\"yes\">EFG1<\/jats:italic>\n                      ).

By formulating curcumin into a stable nanosuspension (CNS), we significantly enhanced its solubility and bioavailability, overcoming a fundamental limitation that has hindered its clinical application. More importantly, we demonstrate that CNS acts synergistically with fluconazole, effectively restoring its efficacy against resistant planktonic cells and biofilms through dual mechanisms: increasing intracellular drug accumulation by inhibiting efflux pumps and suppressing key virulence traits including hyphal formation and adhesion. This combinatory approach not only reduces the required drug dosage and potential toxicity but also provides a promising therapeutic avenue against biofilm-associated refractory candidiasis. Our findings highlight the potential of harnessing natural product-nanocarrier systems to extend the lifespan of existing antifungals and combat drug-resistant fungal infections.\n                      <\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.01520-25","type":"journal-article","created":{"date-parts":[[2025,10,31]],"date-time":"2025-10-31T12:49:21Z","timestamp":1761914961000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Nanotechnology-driven synergy: research effects of curcumin nanosuspension and fluconazole combination in overcoming azole resistance in\n                    <i>Candida albicans<\/i>"],"prefix":"10.1128","volume":"13","author":[{"given":"Cheng","family":"Zhang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0220qvk04","id-type":"ROR","asserted-by":"publisher"}],"name":"Shanghai Tongren Hospital, Shanghai Jiao Tong University School of Medicine","place":["Shanghai, People\u2019s Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0220qvk04","id-type":"ROR","asserted-by":"publisher"}],"name":"Shanghai Tongren Hospital, Shanghai Jiao Tong University School of Medicine","place":["Shanghai, People\u2019s Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4442-0950","authenticated-orcid":false,"given":"Yunan","family":"Jiang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0220qvk04","id-type":"ROR","asserted-by":"publisher"}],"name":"Shanghai Tongren Hospital, Shanghai Jiao Tong University School of Medicine","place":["Shanghai, People\u2019s Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5930-9297","authenticated-orcid":true,"given":"Shoufu","family":"Sun","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0220qvk04","id-type":"ROR","asserted-by":"publisher"}],"name":"Shanghai Tongren Hospital, Shanghai Jiao Tong University School of Medicine","place":["Shanghai, People\u2019s Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fgb.2017.10.008"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.idc.2021.08.002"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.micpath.2018.02.028"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/pathogens13050426"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/pathogens11030335"},{"key":"e_1_3_2_7_2","first-page":"233","article-title":"Incidence rate of Candida species in the oral cavity of middle-aged and elderly subjects","volume":"51","author":"Zaremba ML","year":"2006","unstructured":"Zaremba ML, Daniluk T, Rozkiewicz D, Cylwik-Rokicka D, Kierklo A, Tokajuk G, Dabrowska E, Pawi\u0144ska M, Klimiuk A, Stokowska W, Abdelrazek S. 2006.
