How nanoparticles could help medication reach the brain | Eden Tanner | TEDxUniversityofMississippi

Quick Overview

Eden Tanner details the development of a technology utilizing ionic liquids coated onto biodegradable nanoparticles to safely deliver therapeutic agents across the blood-brain barrier, demonstrating that 45% of these particles reached the brain in rats after 30 minutes, contrasting sharply with the saline control and indicating a promising, unprecedented level of drug delivery efficacy for treating conditions like glioblastoma, Alzheimer's, and Parkinson's.

Key Points: Nanoparticles coated with ionic liquids successfully delivered therapeutics across the blood-brain barrier (BBB) in rats, demonstrating 45% particle delivery to the brain within 30 minutes post-injection. The experiment compared three conditions: Saline (control, showing no signal), PLGA-DiD (showing minimal signal), and IL-PLGA-DiD (showing strong signal in the brain tissue), confirming the ionic liquid coating's efficacy. The natural transport mechanism of red blood cells, which make up 45% of blood volume, is too slow to deliver therapeutics effectively, necessitating advanced delivery systems. The ionic liquid coating allows the nanoparticles to hitch a ride on red blood cells, protecting the cargo from degradation before reaching the brain. This technology aims to treat challenging neurological conditions such as glioblastoma, Alzheimer's, and Parkinson's disease, where drug delivery to the brain is currently restricted by the BBB. The speaker's lab creates ionic liquids from common ingredients like table salt (sodium chloride) and fatty acids, which are liquid at room temperature.

Context: Eden Tanner, speaking at TEDxUniversity of Mississippi, discusses a novel drug delivery system designed to overcome the blood-brain barrier (BBB), a protective shield that prevents many therapeutic agents from reaching the central nervous system. Her research focuses on using nanoparticles coated with ionic liquids to actively transport drugs or biological molecules, like enzymes or gene therapies, directly into brain tissue, offering new hope for treating devastating neurological disorders.
