Building Nerves in the Lab
(Tuesday July 21 2009)
 | Via EurekAlert!, researchers "report on the first lab-grown motor nerves that are insulated and organized just like they are in the human body. The model system will drastically improve understanding of the causes of myelin-related conditions, such as diabetic neuropathy and later, possibly multiple sclerosis (MS). In addition, the model system will enable the discovery and testing of new drug therapies for these conditions. MS, diabetic neuropathy, and many conditions that are caused by a loss of myelin, which forms protective insulation around our nerves, can be debilitating and even deadly. ... The [team] plans to use their new model system to explore the origins of diabetic neuropathy. Once the causes of myelin degradation are identified, targets for new drug therapies can be tested with the model. Other planned experiments will focus on how electrical signals travel through myelinated and unmyelinated nerves to reveal how nerves malfunction as well as for spinal cord injury studies." Loss of myelin appears to be important in general degenerative aging as well, so advances in understanding here will probably have wider application in the repair of the aging nervous system. |
