Progress and potential of ferritin nanocages for cancer drug delivery

While HFn nanocages show strong promise in vaccine development, their application in cancer treatment faces significant translational challenges. These include limited human data, variability in receptor expression, rapid clearance, and the need for more representative models and scalable manufacturing, though certain untargeted HFn-based systems as Gd-HFn and Dox-HFn appear closer to clinical readiness.
