Targeted Delivery of SmacN7 Peptide Induces Immunogenic Cell Death in Cervical Cancer Treatment.

Abstract

Cervical cancer is a common tumor in women and one of the common causes of cancer death in women. Due to the aggressive and non-specific nature of traditional chemotherapy, there is a growing need for new treatment modalities. Currently, tumor immunotherapy is increasingly garnering attention as a disruptive treatment approach. Therefore, we constructed CCTP-SmacN7, a delivery system capable of releasing active molecules in the tumor microenvironment. CCTP-SmacN7 can not only inhibit tumor proliferation and migration, but also induce tumors to produce large amounts of reactive oxygen species. The production of reactive oxygen species can activate tumors to release or expose damage-associated molecular patterns, promote DC cell maturation, and ultimately activate T cells. Here, we present an innovative targeted treatment approach for cervical cancer. While inducing tumor immunogenic cell death, this program can also improve the tumor microenvironment and initiate the tumor immune cycle.
