Its activity depends on the type of fungus that produces it, the extraction method, and the molecular weight. Materials and Methods: This study evaluated the anti-tumor and immunoregulatory properties of Ganoderma parvulum (GP)-derived polysaccharides. Results: GP crude polysaccharides inhibited mice\u2019s lymphoma without cytotoxicity. In vitro studies showed that exopolysaccharides (GEPS) and intrapolysaccharides (GIPS) of G. parvulum inhibited the proliferation of tumor cells, but no cell death was observed. Significantly, GEPS and GIPS increased the production of nitric oxide, TNF-\u03b1, MCP-1, and an increase in IL-1\u03b2, IL-18, and Caspase-1, while NLRP3 was down-regulated. Also, it decreases the production of IL-10 and IL-6. Conclusion: These observations suggest that GP-derived polysaccharides may exert anti-tumor activity primarily by activating the host\u2019s immune system via macrophage stimulation.<\/jats:p>","DOI":"10.1042\/bsr20240113","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T05:17:14Z","timestamp":1759123034000},"page":"597-613","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["<b>Anti-tumor and immunomodulatory activity of<\/b>\n                    <i>Ganoderma parvulum-<\/i>\n                    derived\n                    <b>polysaccharides<\/b>"],"prefix":"10.1042","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7324-2826","authenticated-orcid":false,"given":"Katherin","family":"Contreras-Ramirez","sequence":"first","affiliation":[{"name":"1Grupo de Investigaciones Biom\u00e9dicas UniRemington, Facultad de Ciencias de la Salud, Corporaci\u00f3n Universitaria Remington, Medell\u00edn, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8058-5886","authenticated-orcid":false,"given":"Xiomara","family":"L\u00f3pez-Legarda","sequence":"additional","affiliation":[{"name":"2Grupo de Investigaci\u00f3n Biopolimer, Facultad de Ciencias Farmac\u00e9uticas y Alimentarias, Universidad de Antioquia UdeA, Medell\u00edn, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4207-7543","authenticated-orcid":false,"given":"Jorge H.","family":"Tabares-Guevara","sequence":"additional","affiliation":[{"name":"3Infettare, Facultad de Medicina.
