Phenolic immunogenic cell death nanoinducer for sensitizing tumor to PD-1 checkpoint blockade immunotherapy

A critical challenge remains in PD-1 checkpoint blockade immunotherapy is few tumor specific T cells infiltration in hypoxic tumor microenvironment (TME). Improving immunogenic cell death (ICD) associated immunogenicity can make tumor sensitive to PD-1 checkpoint blockade immunotherapy. Herein, a phenolic ICD inducer was engineered by self-assembly of the superior ICD inducer (doxorubicin, DOX), phenolic manganese dioxide nanoreactor, ferric...
