This is a preclinical proof-of-concept study in a murine nasopharyngeal carcinoma model demonstrating that a biomimetic cancer cell membrane-coated nanogel carrying chemotherapy and photothermal agents induces immunogenic cell death and promotes anti-tumor T cell responses with abscopal effects. The work is mechanistic and exploratory, appropriate for early-stage nanotechnology development but insufficient to support clinical use.
Preclinical in vivo proof-of-concept study in mouse model. Nasopharyngeal carcinoma-bearing mice. Intervention: IT@PVCL-CM nanogels (indocyanine green and toyocamycin co-loaded poly(N-vinylcaprolactam) nanogels coated with cancer cell membranes) combined with laser irradiation. Compared with: Exosome-coated nanogels mentioned as internal comparison; no standard-of-care comparison reported.
Cancer cell membrane coating conferred better homologous targeting, cellular uptake, and immunogenicity than exosome coating IT@PVCL-CM combined with laser irradiation significantly promoted dendritic cell maturation via ICD and membrane antigens Treatment effectively suppressed both primary and distant tumors via abscopal effect in NPC mouse model

Nasopharyngeal carcinoma (NPC) therapy faces challenges including severe off-target toxicity and immunosuppression. Here, a biomimetic nanogel vaccine is developed based on dual pH/reactive oxygen species (ROS)-responsive poly(N-vinylcaprolactam) (PVCL) nanogels (NGs) that were co-loaded with indocyanine green (ICG) and the endoplasmic reticulum stress-inducing drug toyocamycin, followed by coating with cancer cell membranes (CMs) or exosomes (Exos). Systematic comparison reveals that CM coating confers better homologous targeting, cellular uptake, and immunogenicity than the Exo coating. The optimized IT@PVCL-CM NGs enable tumor microenvironment-triggered drug release, combined chemotherapy and mild photothermal therapy, and synergistic induction of immunogenic cell death (ICD). In an NPC mouse model, the IT@PVCL-CM combined with laser irradiation significantly promotes dendritic cell maturation through the combination therapy-mediated ICD effect and the CM antigens, CD8+ T cell infiltration, and long-term memory T cell responses, effectively suppressing both primary and distant tumors via an abscopal effect. Additionally, ICG endows dual-modal fluorescence and thermal imaging for real-time tumor monitoring. This work presents the integration of dual-responsive PVCL nanogels, dual ICD induction strategies through combination of photothermo-chemotherapy, and biomimetic membrane cloaking for precision NPC theranostics and immune activation.
