Inflammation in type 2 diabetes
Type 2 diabetes can be triggered when obese people develop inflammation in their fat tissue. This leads to a reduced sensitivity to insulin in fat cells.
The activity of immune cells, known as macrophages, within the fat tissue results in this inflammation, with chemical signals then recruiting further macrophages. As more macrophages accumulate in the fat tissue, insulin resistance develops.
Preventing inflammation
EPFL researcher Kristina Schoonjans led a team that discovered a receptor on macrophages that can inhibit the inflammation of type 2 diabetes. Known as TGR5 in the study, this receptor is activated by bile acids, the collective term for chemicals in our bile.
TGR5 was found by the research team to block chemical signals sent by macrophages to attract further numbers. When activated by compounds similar to bile acids, they were found to significantly reduce inflammation associated with type 2 diabetes.
The researchers’ work was published in the Journal of Clinical Investigation, …read more
