摘要

Immune checkpoint inhibitors are transforming cancer treatment,yet the majority of patients fail to achieve complete and durable responses.Resistance to checkpoint blockade is associated with non-immunogenic tumors that lack significant T cell infiltration and are instead characterized by a highly immunosuppressive tumor microenvironment(TME).To reprogram such acolda TMEs to a more ahota T cell-inflamed phenotype,we are developing pH-responsive,asmarta polymer nanoparticles(NPs)for efficient cytosolic delivery of cyclic dinucleotides(CDNs),including 2a3a-cGAMP(cyclic [G(2a,5a)pA(3,5a)p]),the natural and endogenous high affinity ligand of the stimulator of interferon genes(STING)pathway.
