Routing immunomodulatory cytokine-encoded mRNAs to the omentum: turning an enemy into an ally in peritoneal metastasis.

Abstract

Peritoneal metastases remain a significant clinical challenge owing to the immunosuppressive nature of the omentum, which serves as a protective niche for disseminated tumor cells. Our recent study explored the targeted delivery of immunomodulatory cytokine-encoded mRNAs to the omentum, aiming to shift its role from a tumor-supportive site to an immune-activating ally. Our findings highlight the potential of cytokine mRNA delivery as a novel and safe immunotherapeutic strategy for peritoneal metastases.
