What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology.
– These articles focus mainly on neurology research.
– What is neurology?
– Definition of neurology: a science involved in the study of the nervous systems, especially of the diseases and disorders affecting them.
– Neurology research can include information involving brain research, neurological disorders, medicine, brain cancer, peripheral nervous systems, central nervous systems, nerve damage, brain tumors, seizures, neurosurgery, electrophysiology, BMI, brain injuries, paralysis and spinal cord treatments.
What is Psychology?
Definition of Psychology: Psychology is the study of behavior in an individual, or group. Our psychology articles cover research in mental health, psychiatry, depression, psychology, schizophrenia, autism spectrum, happiness, stress and more.

Summary: Diets high in guar gum, a dietary fiber and common food additive extracted from guar beans, limit inflammation and delay the onset of multiple sclerosis in mouse models.

Diets high in guar gum, a common food additive and dietary fibre, limited inflammation and delayed the onset of multiple sclerosis (MS) symptoms in mice, according to new research by members of the University of British Columbia (UBC) Microbiology and Immunology department.
“The rapid increase of autoimmune and inflammatory disorders in industrialized countries in the last few decades indicates dietary choices are one environmental factor contributing to incidence,” said Dr. Lisa Osborne, senior researcher on the study and an assistant professor with UBC Microbiology and Immunology.
“Dietary fibres are potent modulators of immune responses and can control inflammation in multiple diseases, but they’re a very biochemically diverse family. Our study gives us a clearer window into the potential of several sources of fibre in maintaining immune health.”
Dr. Osborne and colleagues exposed groups of mice to a variety of diets—a control five percent cellulose fibre diet, a diet entirely lacking in dietary fibre, or diets enriched (30%) with fibre in either resistant starch, inulin, pectin, or guar gum. Quar gum was the only fibre type that significantly limited the MS-like symptoms. 
Guar gum—guaran—is extracted from guar beans, and is often used as an additive to thicken and stabilize food and animal feed, and in industrial applications. India and Pakistan are major growers of the bean.
“Guar beans aren’t that common in western diets, and the gum isn’t used at these high levels as an additive in the west,” says Naomi Fettig, first author on the study and a PhD student with the Department of Microbiology and Immunology at UBC.
“Experts have consistently been saying fibre is good for you—and a variety of fibre sources is important to immune health—but there hasn’t been very much critical work into identifying how the body responds to different fibre types. It’s fascinating that this particular source has such an impact.”
In the US and Canada, the average daily intake of fibre is 15 grams—current recommendations are double that at 30 grams. The recommended values don’t take into account any specific fibre type.
“Incorporating guar beans might be challenging to achieve at the doses we gave to mice,” says Dr. Osborne. “But a guar gum derivative, partially hydrolyzed guar gum, is commercially available as a prebiotic.”
After the gum is broken down by the microbiota of mice, the resulting molecules appeared to reduce the activity and proliferation of a type of CD4+ T cells, Th1 cells, that play a key part in activating the autoimmune response. It’s that response that leads to MS-like symptoms in mice.
The effects of fibre on Th1 cells remained largely unknown prior to this study, and these findings suggest that the biochemical differences in fibre structures can influence diverse immune pathways.   
Dr. Osborne and her lab now want to explore the potential benefits in humans—including developing a more detailed understanding of the molecular picture, which might help design therapeutics that offer the benefits of such high guar gum diets in a more practical form.

Inhibition of Th1 activation and differentiation by dietary guar gum ameliorates experimental autoimmune encephalomyelitis” by Lisa Osborne et al. Cell Reports
Abstract
Inhibition of Th1 activation and differentiation by dietary guar gum ameliorates experimental autoimmune encephalomyelitis
Dietary fibers are potent modulators of immune responses that can restrain inflammation in multiple disease contexts.
However, dietary fibers encompass a biochemically diverse family of carbohydrates, and it remains unknown how individual fiber sources influence immunity.
In a direct comparison of four different high-fiber diets, we demonstrate a potent ability of guar gum to delay disease and neuroinflammation in experimental autoimmune encephalomyelitis, a T cell-mediated mouse model of multiple sclerosis.
Guar gum-specific alterations to the microbiota are limited, and disease protection appears to be independent of fiber-induced increases in short-chain fatty acid levels or regulatory CD4+ T cells. Instead, CD4+ T cells of guar gum-supplemented mice are less encephalitogenic due to reduced activation, proliferation, Th1 differentiation, and altered migratory potential.
These findings reveal specificity in the host response to fiber sources and define a pathway of fiber-induced immunomodulation that protects against pathologic neuroinflammation.
Could you pls specify who funded this project? Thanks
I am so glad I have this source for all kinds of studies on so many varied conditions and diseases ! Bless you and all who participate in this challenging work and publications of said types of research !!
Guar gum in huge doses reverses Ms. Yet u don’t provide the control models or anything. Your just trying to sell or promote guar supplements. This form of marketing should be illegal and I’d love to know the unknown dose given to the mice
Bet it was ridiculous and maybe fatal for humans
Please read the full, open-access research paper for the information you requested. The link is available at the foot of the article. This is a scientific research paper, not a promotional piece for dietary supplementation. Concerns can be raised to the researchers at the University of British Columbia who conducted this scientific study. Thank you.
