Coating for Amyloid (IMAGE) University of California - San Diego Caption Clear strands of toxic aggregated amyloid beta peptides, a hallmark of Alzheimer's disease, interact with proteins such as the anti-oxidant enzyme catalase, shown in red. The interaction disables catalase, resulting in oxidative damage to neural cells in culture. Protein-resistant coating (blue) on the aggregated amyloids inhibit these harmful interactions and protect of cells from amyloid beta-induced oxidative stress and toxicity.
