SHR # 2842:: Scientists Identify Gut-derived Metabolites that Play a Role in Neurodegeneration plus Sun Damage - Copper peptides Can Repair and Protect - Professor Patrizia Casaccia,PHD - Debbi Barber - Dr. Suzanne Turner, MD - A New York-based, multi-institutional research team has found high levels of three toxic metabolites produced by gut bacteria in the cerebrospinal fluid and plasma samples of multiple sclerosis (MS) patients. The important findings, published in the journal Brain, further scientists’ understanding of how gut bacteria can impact the course of neurological diseases by producing compounds that are toxic to nerve cells. PLUS Sun exposure is an important factor in health. But modern culture says avoid the sun as it ages skin prematurely. What's a person to do? We have the answer.
