Precision nano therapy targets tumor nerves in pancreatic cancer

Announcing a new publication for Acta Materia Medica journal. A preclinical study has developed a precision nano-intervention strategy targeting tumor-associated nerves to destroy nerve-fueled tumor growth in pancreatic cancer.

In this strategy, Escherichia coli Nissle 1917-derived outer membrane vesicles (OMVs) are decorated with nerve-binding peptide for targeted delivery of co-loaded tropomyosin receptor kinase (Trk) inhibitors to tumor-associated nerves, thus precisely inhibiting nerve activity through the neurotrophin/Trk signaling pathway. Furthermore, the OMVs trigger M2-M1 switching, thus accelerating nerve injury.

This nano-intervention strategy significantly enhances chemotherapy efficacy in pancreatic cancer.
