Dysbiosis News and Research

RSS

Dysbiosis is a condition caused by an imbalance in the bacterial community (microbiome) of the human gut. Dysbiosis disrupts the ecoystsem of the gut, resulting in symptoms such as diarrhea, constipation, bloating, and indigestion, among others.

Gut immune cells linked to worsening rheumatoid arthritis

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of "good" microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.
