Students at the University of Waterloo are investigating how an antioxidant found in green tea may protect neuronal cell membranes from damage associated with Alzheimer's disease.
Key facts
- •Charlotte Baur, Hugh Hossfeld, and Isabella Barichello are conducting the research under the supervision of Dr. Zoya Leonenko.
- •EGCG is a plant antioxidant found in green tea that is being tested for its ability to shield neuronal membranes.
- •Amyloid beta forms protein clusters that create plaques and damage cell membranes, contributing to Alzheimer's disease.
- •Baur and Hossfeld observed that EGCG reduced membrane permeability during their electrophysiology experiments.
- •Barichello uses surface plasmon resonance to study how EGCG affects the binding of amyloid beta to the membrane surface.
Three University of Waterloo students are conducting research in Dr. Zoya Leonenko's laboratory to explore how epigallocatechin gallate (EGCG), an antioxidant found in green tea, might prevent cell damage linked to Alzheimer's disease. The team is examining how this compound interacts with neuronal cell membranes to potentially block the harmful effects of amyloid beta, a protein cluster that forms plaques in the brain.
Investigating Membrane Protection
Research assistants Charlotte Baur and Hugh Hossfeld are using electrophysiology techniques to model neuronal cell membranes and study how they conduct ion currents. They are specifically testing how amyloid beta oligomers create pore-like openings in these membranes, which allows ions to pass through abnormally. By applying EGCG, the researchers observed a reduction in membrane permeability, suggesting the extract may provide a protective barrier against amyloid-induced damage.
Analyzing Molecular Binding
Isabella Barichello is approaching the research from a different perspective using surface plasmon resonance (SPR). Her work focuses on how amyloid beta attaches to the surface of the membrane and whether EGCG treatment can effectively reduce or prevent this buildup. Barichello has designed experimental protocols and analyzed molecular binding patterns to determine if the extract can inhibit the accumulation of amyloid proteins on the membrane surface.
Building on Previous Research
The current study in the Department of Physics and Astronomy builds upon earlier investigations into the protective potential of compounds such as trehalose and melatonin. By analyzing the interaction between EGCG and neuronal membranes, the team aims to provide insights into whether reducing membrane damage could eventually slow or prevent the progression of Alzheimer's disease.
