Abstract
Alzheimer`s disease affects 10 million Americans and 44 million people worldwide. There are various biochemical mechanisms and processes that play a role in Alzheimer´s disease. These mechanisms are debated in the literature and there is currently no efficient drug that halts the progress of the disease. Efficient and effective drug design studies require detailed understanding of associated biochemical and biophysical mechanisms at the atomic level with dynamics. We investigate all biochemical processes and mechanisms associated with Alzheimer´s disease using quantum chemistry, statistical mechanics, bioinformatics, artificial intelligence and experiments. Using the information that we gain from biochemical investigations, we design monoclonal antibodies in collaboration with pharmaceutical companies. In this talk, we will present some of our studies about the roles of genetics, mitochondrial dysfunction and oxidative stress mechanisms in Alzheimer´s disease. Our theoretical and experimental results show that ATP reduces the fibrillization of disordered amyloid-β, transition metal ion coordination with amyloid-β increases the fibrillization progress and genetic factors significantly impact the fibrillization and aggregation properties of amyloid-β alloforms. Furthermore, we will provide insights into monoclonal antibody design for the treatment of Alzheimer´s disease.
