Systemic toxicity and immunotoxicity studies of glucose oxidase-loaded extracellular vesicles derived from lung cancer cells. (PubMed, Front Immunol)
Additional controls included mice receiving keyhole limpet hemocyanin (KLH) as an immunostimulatory reference (a single intraperitoneal dose of 100 mg·kg-1 on day 14) and cyclosporine A as an immunosuppressive control (oral administration of 100 mg·kg-1 on days 1, 7, and 14)...GOX-loaded EV treatment induced a chemokine-biased transcriptional response, characterized by upregulation of Cxcl9 and modest increases in Cxcl3, Cxcl16, Ccl5, Ccl12, and Ccl17, while canonical pro-inflammatory cytokines showed minimal changes. GOX-loaded EVs demonstrate a favorable short-term in vivo safety profile and a constrained immunological signature, engaging immune pathways in a context-dependent manner rather than acting as classical immune adjuvants, thereby supporting their potential as controllable immunomodulatory therapeutic platforms.
