Extracellular vesicles (EVs) secreted by malignant melanocytes play a vital role in developing tumor-promoting microenvironments, but it is unclear whether this is mediated through CD36. To understand the role of CD36 in melanoma, we first analyzed the SKCM dataset for clinical prognosis, evaluated the percentage of CD36 in lymphatic fluid-derived EVs (LEVs), and tested whether melanoma-derived EVs increase CD36 expression and induce M2-macrophage-like characteristics. Furthermore, we performed a multiplex immunofluorescence (MxIF) imaging analysis to evaluate the CD36 expression and its colocalization with various other cells in the lymph node (LN) of patients and control subjects. Our findings show that cutaneous melanoma patients have a worse clinical prognosis with high CD36 levels, and a higher percentage of CD36 in total LEVs were found at baseline in melanoma patients compared to control. We also found that monocytic and endothelial cells treated with melanoma EVs expressed more CD36 than untreated cells. Furthermore, melanoma-derived EVs can regulate immunosuppressive macrophage-like characteristics by upregulating CD36. The spatial imaging data show that cells in tumor-involved sentinel LNs exhibit a higher probability of CD36 expression than cells from control LNs, but this was not statistically significant. Conclusively, our findings demonstrated that CD36 plays a vital role in controlling the immunosuppressive microenvironment in the LN, which can promote the formation of a protumorigenic niche.<\/jats:p>","DOI":"10.3390\/biom14070837","type":"journal-article","created":{"date-parts":[[2024,7,12]],"date-time":"2024-07-12T11:28:03Z","timestamp":1720783683000},"page":"837","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Melanoma-Derived Extracellular Vesicles Induce CD36-Mediated Pre-Metastatic Niche"],"prefix":"10.3390","volume":"14","author":[{"given":"Shankar","family":"Suman","sequence":"first","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wendy K.","family":"Nevala","sequence":"additional","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexey A.","family":"Leontovich","sequence":"additional","affiliation":[{"name":"Department of Quantitative Health Sciences, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0806-0222","authenticated-orcid":false,"given":"Caitlin","family":"Ward","sequence":"additional","affiliation":[{"name":"Division of Biostatistics and Health Data Science, University of Minnesota, Minneapolis, MN 55455, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8005-1072","authenticated-orcid":false,"given":"James W.","family":"Jakub","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mayo Clinic, Jacksonville, FL 32224, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yohan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Urology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liyi","family":"Geng","sequence":"additional","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noah A.","family":"Stueven","sequence":"additional","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chathu L.","family":"Atherton","sequence":"additional","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4196-1804","authenticated-orcid":false,"given":"Raymond M.","family":"Moore","sequence":"additional","affiliation":[{"name":"Department of Computational Biology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8844-4391","authenticated-orcid":false,"given":"Jill M.","family":"Schimke","sequence":"additional","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6149-345X","authenticated-orcid":false,"given":"Fabrice","family":"Lucien-Matteoni","sequence":"additional","affiliation":[{"name":"Department of Urology, Mayo Clinic, Rochester, MN 55905, USA"},{"name":"Department of Immunology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah A.","family":"McLaughlin","sequence":"additional","affiliation":[{"name":"Department of Surgery, Mayo Clinic, Jacksonville, FL 32224, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetomir N.","family":"Markovic","sequence":"additional","affiliation":[{"name":"Department of Oncology, Mayo Clinic, Rochester, MN 55905, USA"},{"name":"Department of Immunology, Mayo Clinic, Rochester, MN 55905, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e20211314","DOI":"10.1084\/jem.20211314","article-title":"CD36, a signaling receptor and fatty acid transporter that regulates immune cell metabolism and fate","volume":"219","author":"Chen","year":"2022","journal-title":"J.
