| Research Abstract |
1.Hyperthermia using MCL for various carcinoma cells
Intracellular hyperthermia using magnetite cationic liposomes (MCL) was very effective for various carcinoma animal models (rabbit, hamster, rat and mouse).
2.Immune induction in lymph node using MCL-hyperthermia system
Selective hyperthermia using magnetoliposomes was found to induce immune responces in lymph node. Immune cells (NK cells, T cells and dendritic cells) were activated.
3.Targeting ability in tumor cells and intracellular hyperthermia using AML
Antibody-conjugated magnetoliposomes (AML) were developed. The monoclonal antibody to renal cell carcinoma was bound to the magnetoliposomes. This AML accumulated only renal cell carcinoma when AML was injected in vein, and intracellular hyperthermia was very effective.
4.Hyperthermia for human prostate cancer and hereditary melanoma in a mouse model
Heat can kill any cells. This was checked not only for mouse or rat carcinoma cells, but also for human prostate cancer and hereditary melanoma in a mouse model. Repeated hyperthermia was more effective compared with a single hyperthermia treatment.
5.Activation mechanisms for immune response in hyperthermia
By applying hyperthermia treatment, a lot of heat shock proteins were produced. Heat shock protein 70 chaperons tumor peptides, which induces immune response to the tumor.
