In a study published in the Journal of Extracellular Vesicles, scientists from the UF Health Cancer Institute have found a way to make treatment for a notoriously aggressive breast cancer more effective. Using a delivery system that relies on extracellular vesicles (small, lipid nanoparticles secreted from a myriad of cell types), the team was able to circumvent two common difficulties associated with a targeted treatment for triple negative breast cancer: access to tumor sites and stable and effective transport in the body.
