Expression of inducible damage-associated molecular patterns after interleukin-12 gene electrotransfer in mouse melanoma and colorectal cell linesMedved, Ajda (Avtor) Omerzel, Maša (Avtor) Jesenko, Tanja (Avtor) Buček, Simon (Avtor) Serša, Gregor (Avtor) Čemažar, Maja (Avtor) gene electrotransfercytokineinterleukin-12Interleukin-12 (IL-12) has demonstrated potent antitumor effects by activating natural killer (NK) and T cells, but its systemic administration poses challenges due to toxicity. This study investigated gene electrotransfer (GET) as a localized delivery method for IL-12 plasmids in B16F10 and CT26 tumor cells and its effect on the expression of damage-associated molecular patterns (DAMPs) and several cytokines. We observed the activation of cytosolic sensors and cytokine production, with the expression of IL-6 and TNF-α upregulated only after IL-12 GET, suggesting the involvement of inducible damage-associated molecular patterns (iDAMPs) in the immune response to IL-12 gene therapy. These findings highlight the multifaceted immune activation triggered by GET, offering insights for improving IL-12-based cancer therapies.Elsevier Masson SAS20252025-11-27 03:58:38Neznano24410UDK: 602.6/.7ISSN pri članku: 1950-6007DOI: 10.1016/j.biopha.2025.118414COBISS_ID: 246024963slby Authors
