Research led by Drs. Yuhai Zhao and Walter J Lukiw at the LSU Health New Orleans Neuroscience Center and the Departments of Cell Biology and Anatomy, Neurology and Ophthalmology, reports for the first time a pathway that begins in the gut and ends with a potent pro-inflammatory toxin in brain cells contributing to the development of Alzheimer’s disease (AD). They also report a simple way to prevent it. Results are published in Frontiers in Neurology.
