A nanoscale drug carrier capable of crossing the blood-brain barrier. Said carrier can target brain lesions (brain tumors or other neurodegenerative diseases). The targeting drug carrier capable of crossing the blood-brain barrier comprises all-heavy-chain human ferritin or a functional fragments reconstituted structure or a mutant thereof. The manner for crossing the blood-brain barrier of the drug carrier is receptor-mediated transcytosis. The drug carrier provides an effective nanoscale drug carrier for the treatment of brain tumors or other neurodegenerative diseases.

Nanoscale drug carrier capable of passing through blood-brain barrier

The present disclosure relates to a tumor-targeted drug delivery system, comprising a tumor-targeted drug carrier and a tumor-treating drug, wherein the tumor-targeted drug carrier comprises full heavy-chain human ferritin. The present disclosure also relates to a method for preparing the tumor-targeted drug delivery system comprising: depolymerizing a polymerized full heavy-chain human ferritin; adding a tumor-treating drug to the depolymerized full heavy-chain human ferritin so as to bind the tumor-treating drug to the depolymerized full heavy-chain human ferritin; and re-polymerizing the depolymerized full heavy-chain human ferritin bound with the tumor-treating drug to form a nanoparticle.
