Inhibition of glioma development by doxorubicin-photochemical internalization generated macrophage vaccine: a survival study in rats
Highlights
Photochemical internalization of doxorubicin (DOX-PCI) increased glioma immunogenic cell death (ICD) compared to DOX acting as a single agent.
F98 glioma cells, treated with DOX-PCI in vitro, induced a significantly higher level of the ICD markers HGMB1, HSP70, and HSP90 than DOX acting alone
Macrophages primed with DOX-PCI treated glioma cells appeared to be highly effective as an antigen presenting cells anti-tumor vaccine.
Inoculation of host animals could delay and in some cases, prevent tumor development.
In a curative treatment protocol, a second booster inoculation significantly improved survival, with 60% of the animals alive at day 60.
Conclusion
Macrophages primed with DOX-PCI treated glioma cells appeared to be highly effective as APCs and, when injected into host animals, could delay and, in some cases, prevent tumor development.
