Tumor-targeted CD40 ligand-functionalized extracellular vesicle mimetics enable chemoimmunotherapy for neuroblastoma.
Neuroblastoma remains one of the most lethal pediatric solid tumors, and durable control of high-risk disease is hindered not only by inefficient tumor-selective drug delivery but also by a profoundly immunosuppressive tumor microenvironment. To address these dual barriers, we developed a chemoimmunotherapeutic vesicle...
