Scientists identify Gut-derived Metabolites that play a role in Neurodegeneration

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.

Previously published evidence has supported the concept that an imbalance in the gut microbiota—the community of organisms that live in the human intestines—may underly a range of neurological disorders...

Tiny Bubbles can be Future Treatment for Inflammation

Multimeric decoy receptor EV-sorting protein chimaera is functionalized on several EV subpopulations.

Scientists hope that tiny sacs of material excreted by cells — so-called extracellular vesicles — can be used to deliver drugs inside the body. Researchers at Karolinska Institutet now show that these nanobubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique, which is presented in Nature Biomedical Engineering, shows promising results in animal models.

Extracellular vesicles (EVs) are important in inter-cellular communication as carriers of biological signals. They are nanometre-sized membrane-coated packages excreted by cells that can deliver fatty acids, proteins and genetic material to different tissues.

The tiny bubbles are f...

Over-the-Counter antioxidant lipoic acid holds promise in improving patients’ lives after an OHSU pilot study. Treatment options currently are limited for people suffering from secondary progressive MS. The randomized double-blind study involved 51 participants who completed the 2-year trial. 27 people were given a 1,200-milogram daily dose of lipoic acid, with the remaining 24 participants given a placebo. Researchers are using the findings from the pilot trial to design the expanded multi-site clinical trial to begin later this year in Portland and other sites that have yet to be finalized.

“These are high doses,” said Rebecca Spain, M.D...
