Background:
Cervical cancer treatment faces challenges in identifying specific targets within heterogeneous tumors. Current antitumor immunotherapy for cervical cancer is constrained by the lack of corresponding therapeutic targets.
Methods:
We developed glycoprotein E (gE)-pHLIP nanomicelles, an antigen-targeting peptide particle anchored on cell membranes. This system enables tumor-targeted antigen release, labels tumor tissues, and leverages pre-existing immune responses for tumor elimination by "disguising" cancer cells as viral invaders.
Results:
In animal models, pre-immunization with g(E) combined with g(E)-pHLIP treatment demonstrated suppressed tumor growth. Reduced tumor recurrence was observed post-treatment. The system successfully activated the body's antiviral immune response against labeled tumor cells.
Conclusions:
This study developed a novel protein-peptide system that labels cervical cancer cells, "disguises" them as viral invaders to the body, and subsequently eliminates tumors through the body's antiviral immune response.
Insights
This study introduces a novel glycoprotein E (gE)-pHLIP nanomicelle system for cervical cancer. This immunotherapy approach disguises cancer cells as viral invaders, activating the immune system to eliminate tumors and reduce recurrence.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
