A nanomedicine-based strategy for chemo-immunotherapy (CIT) of glioblastoma (GBM), which has the worst prognosis among brain tumors, was successfully developed. In vivo experiments demonstrated that the combined use of epirubicin-encapsulating nano-micelles (Epi/m) with immune checkpoint inhibitors (ICI) eradicated PTEN-negative GBM, which is highly resistant to ICI alone. Due to the synergistic effects of Epi/m plus ICI combination, the number of tumor-infiltrating T cells (TIL) and other antitumor immune cells significantly increased to kill cancer cells effectively.
