Precision Attack: GD2-Directed siRNA-Lipid Nanoparticles to Target Neuroblastoma’s Weak Spots

Introduction: Neuroblastoma is an aggressive pediatric cancer requiring more effective and less toxic therapies. One promising strategy involves using short interfering RNA (siRNA) to silence cancer dependency genes, which are crucial for cancer cell survival. To deliver siRNA effectively to tumors, improvements to the gold standard delivery vehicle, lipid nanoparticles (LNPs), are needed. Here, we developed targeted LNPs using a bispecific antibody (BsAb) that recognizes the neuroblastoma antigen GD2 and polyethylene glycol (PEG), to improve delivery of siRNAs targeting dependency genes in neuroblastoma.
