Abstract

Nanoparticles of biological origin exhibit many unique properties in biological applications due to their exquisite structure, specific composition, and natural biological functionality. In this study, we obtained lysosomes from three distinct cell types (one normal cell and two activated immune cells) and demonstrated their potential as natural therapeutic nanoparticles for tumor therapy. In vitro experiments revealed that these lysosomes maintained their structural integrity, were well-distributed, and exhibited significant biological activity, which effectively induced Cancer cell death by generating ROS and disrupting biological substrates. Additionally, in vivo investigations showed that these lysosomes could accumulate in tumor tissues after intravenous administration and exhibited exceptional therapeutic effects through the destruction of tumor blood vessels and the degradation of immunosuppressive proteins, with complete tumor disappearance in a single treatment. This research on the utilization of bioactive lysosomes for tumor treatment provides valuable insights into drug development and tumor treatment, particularly when conventional approaches have proven ineffective.
