Supernatants from FM 1-43-stained Cap67 cultures successfully transferred fluorescence to previously unstained cells, suggesting EV-mediated lipid exchange. The removal of EVs through ultracentrifugation of the supernatants effectively nullified this observation. A transwell system separating stained donor and unstained acceptor cells by a 0.4 \u00b5m membrane demonstrated that fluorescence transfer occurred without direct cell contact, with stronger signals observed when acapsular cells were used as donors. Using this model and acapsular\n                      <jats:italic toggle=\"yes\">C. neoformans<\/jats:italic>\n                      cells as lipid acceptors, interspecies lipid transfer was detected when\n                      <jats:italic toggle=\"yes\">Cryptococcus deuterogattii<\/jats:italic>\n                      and\n                      <jats:italic toggle=\"yes\">C. albicans<\/jats:italic>\n                      were used as donor cells, although fluorescence levels were lower compared to intraspecies exchanges.

Here, we provide experimental evidence that lipids can be exchanged between fungal cells via EVs, visualized using the lipophilic dye FM 1-43. This approach allows tracking of lipid trafficking between cells of the same or different species, even in the absence of direct contact. Understanding EV-mediated lipid exchange may offer insights into fungal physiology, signaling, and adaptation. These findings establish a model that can be broadly applied to study vesicle biology and intercellular communication in other microorganisms.<\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.03604-25","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T14:01:01Z","timestamp":1771596061000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["An experimental approach to investigate extracellular vesicle-mediated transfer of lipids between fungal cells"],"prefix":"10.1128","volume":"14","author":[{"given":"Lucas de O.","family":"Las-Casas","sequence":"first","affiliation":[{"name":"Instituto Carlos Chagas, Funda\u00e7\u00e3o Oswaldo Cruz (Fiocruz)","place":["Curitiba, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel A.","family":"Mellon","sequence":"additional","affiliation":[{"name":"Instituto Carlos Chagas, Funda\u00e7\u00e3o Oswaldo Cruz (Fiocruz)","place":["Curitiba, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B\u00e1rbara T.","family":"Bezerra","sequence":"additional","affiliation":[{"name":"Instituto Carlos Chagas, Funda\u00e7\u00e3o Oswaldo Cruz (Fiocruz)","place":["Curitiba, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e1ssia M.","family":"Souza","sequence":"additional","affiliation":[{"name":"Instituto Carlos Chagas, Funda\u00e7\u00e3o Oswaldo Cruz (Fiocruz)","place":["Curitiba, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Flavia C.
