What is it about?

Professor Dietrich Büsselberg of Weill Cornell Medicine-Qatar is a physiologist and biophysicist who has dedicated the past 30 years of his career to researching the mechanisms by which metal ions, metal-containing organic compounds, and other biologically active compounds influence the human nervous system.

A particular focus of Professor Büsselberg’s work is investigating how various substances can modulate neuronal communication and how they interfere with calcium-dependent pathways, which play particularly important roles in triggering apoptosis (i.e., programmed cell death or “cellular suicide”). To understand this issue, his team has conducted research into (1) how metal ions and metal-containing compounds interact with proteins in the cell membrane that regulate the excitability of neurons; (2) how they affect the entry of calcium into the cell and the release of calcium from intracellular stores, both of which play important roles in controlling various biochemical pathways; and (3) how changes in intracellular calcium levels can influence the processing of pain sensations.

Professor Büsselberg’s research group has also explored the processes underlying the generation of respiratory rhythms. Over the past 15 years, his laboratory has also conducted research into the use of natural substances to treat pain and such maladies as cancer, diabetes, and obesity. Of particular importance is his research into flavonoids, compounds of plant origin that can help treat diabetes. Professor Büsselberg has also suggested the possibility of using a drug called metformin in treating COVID-19. Incidentally, this drug is based on plant-derived chemicals and underlines the importance of Professor Büsselberg’s research on botanicals in treating well-known as well as newly emerging diseases.

Why is it important?

The work occurring in Professor Büsselberg’s laboratory has the potential to yield important medical advances. Professor Büsselberg’s overall goal is to help scientists understand the circumstances under which specific drugs or chemicals can have toxic effects and the intracellular mechanisms by which these drugs or chemicals can also have clinical benefits, such as anticancer activity. In pursuit of this goal, Professor Büsselberg has published articles about using the diabetes drug metformin to treat COVID-19, using plant-derived therapies to fight the most aggressive forms of breast cancer, and using plant-derived chemicals called flavonoids to treat diabetes.
