Reprogramming Immunosuppressive Niches and the Cancer Immunity Cycle in Pancreatic Cancer with Neoantigen mRNA Plus Immune Adjuvant Nanocarrier Strategies. (PubMed, ACS Nano)
Clinically, the autogene cevumeran (BNT122) mRNA-lipoplex vaccine demonstrated that individualized neoantigen delivery can elicit durable, tissue-resident CD8+ T cells and prolong recurrence-free survival in resected PDAC, marking a breakthrough in restoring adaptive immunity to an otherwise "cold" tumor...Complementary silicasome platforms (lipid bilayer coated mesoporous silica nanoparticles) encapsulating irinotecan to induce immunogenic cell death (ICD) synergize with spleen-targeting LNPs carrying KRAS mRNA and TLR7/8 agonists, thereby bridging local antigen release with systemic T-cell priming. Together, these studies establish a translational framework wherein nanoparticle-based immunotherapy can both enhance and extend the benefits of mRNA vaccines from localized to metastatic PDAC. By integrating ICD induction, neoantigen targeting, and immune niche reprogramming, these modular nanomedicine platforms offer a realistic path toward scalable, durable, and systemically effective PDAC immunotherapy.
