39: The Surprising Health Benefits of Botox by Carry the One Radio published on 2014/02/03 21:35:27 +0000 A neurobiologist discusses the medical uses of Botox Guest: Dr. Edwin Chapman, University of Wisconsin - Madison and HHMI (Part 2) Hosts: Sama Ahmed (@ColumboAhmed) and Samantha Ancona Esselmann More at: http://ctoradio.org/episode/2013-08-15 ---- In the second part of our talk with Dr. Chapman, we discuss the positive effects that botulinum toxin A, otherwise known as Botox, can have in combating a number of medical conditions. You will be surprised by how often Botox is used for non-cosmetic procedures. It is prescribed for carpal tunnel syndrome, stuttering, excess sweating, cervical dystonia, and other debilitating conditions. Botulinum toxin A works by cleaving proteins important for cell communication (as discussed in Part 1), but exactly how it acts through the nervous system is unclear. Dr. Chapman’s lab has discovered that neurotoxins such as botulinum toxin A can be absorbed by neurons through vesicles at one end of the cell and be transported backward to the neurons connected to it on the other end of the cell, affecting specific proteins in long chains of cells. His research provides important insights into the mechanism of how this useful toxin works.
