magnetite cationic liposome

Magnetite cationic liposomes (MCLs) are specialized nanoparticles composed of a magnetite (Fe3O4) core encapsulated within a cationic lipid bilayer. They are primarily developed for use in magnetic hyperthermia therapy (MHT), a treatment modality where an external alternating magnetic field (AMF) is applied to induce the magnetite nanoparticles to generate localized heat. This heat causes direct thermal ablation of tumor cells and can trigger immunogenic cell death (ICD), which releases tumor-associated antigens and danger signals to stimulate a systemic anti-tumor immune response. The cationic surface charge of the liposome is designed to enhance cellular uptake and retention within the tumor tissue through electrostatic interactions with negatively charged cell membranes. Research has also explored conjugating MCLs with antibodies, such as anti-PD-L1, to combine localized thermotherapy with targeted immunotherapy.
