Scientists have found that targeting micro-organisms in the gut, known as microbiota, could have the potential to prevent type 1 diabetes. University of Queensland researcher Dr. Emma Hamilton-Williams investigated differences in the gut microbiota, comparing those susceptible to type 1diabetes to those protected against the autoimmune disease.
This research has shown there is a genetic component to microbiota and the immune response involved in regulating it, this means that changes in the microbiota in type 1 diabetes occur before symptoms develop, and are not just a side-effect of the disease. Therapies targeting the microbiota could therefore have the potential to help prevent type 1 diabetes in the future.
An immunotherapy targeting T-cells associated with type 1 diabetes resulted in dramatic changes in the gut biology and altered the microbiota in mice models. Genetic susceptibility and change in immune system function led to alterations in the microbiota. The implications are that a person’s genetics contribute to an unhealthy microbiota as well as their diet.
