This is a preclinical materials science and immunology study reporting in vitro and in vivo characterization of a novel CD44-targeted nanocomposite integrating chemotherapy, redox activity, and immunomodulation in a single bladder cancer model. The work demonstrates proof-of-concept that the nanocomposite couples mitochondrial stress with immune remodeling and improves intratumoral retention, but lacks comparative efficacy data, control arms, and quantified survival or regression metrics needed to assess therapeutic potential.
Preclinical in vivo proof-of-concept study. Bladder cancer model; species and strain not explicitly stated; in vitro mechanistic work and in vivo efficacy assessment.. Intervention: CD44-targeted nanocomposite (HPPZC) comprising hyaluronic acid, polydopamine, protamine, zinc oxide, and camptothecin, assembled by microwave-assisted synthesis.
HPPZC induces rapid mitochondrial depolarization and elevates oxidative stress in vitro In vivo HPPZC treatment prolonged local intratumoral retention and produced tumor regression (quantification not provided) HPPZC suppresses CXCL12 and PD-L1, promotes M1-like marker profile, and increases CD8⁺ T-cell infiltration

Bladder cancer therapy is frequently limited by inefficient drug retention and adaptive immune resistance within a hypoxic tumor microenvironment. Here, we report a CD44-targeted, fully synthetic nanocomposite (HPPZC) that converts chemotherapy into a mitochondria-associated therapeutic strategy accompanied by tumor immune remodeling. Rapid microwave-assisted assembly integrates hyaluronic acid (HA), polydopamine (PDA), protamine, zinc oxide (ZnO), and camptothecin (CPT) into a structurally integrated hybrid nanocomposite with tumor targeting, while the PDA/ZnO interface functions as a redox-active platform associated with mitochondrial dysfunction and redox modulation. HPPZC induces rapid mitochondrial depolarization, elevates oxidative stress, and is associated with PINK1/Parkin-related mitochondrial quality-control and autophagy-associated turnover signatures. In vivo, HPPZC treatment prolonged local intratumoral retention and produced tumor regression. The combination of chemotherapy with mitochondrial stress and tumor immune remodeling, suppressing CXCL12 and PD-L1, promoting M1-like marker profile, and increasing CD8⁺ T-cell infiltration. This work establishes a reproducibly fabricated redox-active nanotherapeutic associated with mitochondrial stress that couples targeted chemotherapy with immune microenvironment remodeling for antitumor efficacy.
