Newly identified protein may prevent development of obesity driven diabetes.

obesityResearchers from Maynooth University have identified a new produced by the human body which may have the potential to impact on obesity related diabetes. Diabetes is a and obesity is a key driver of .

The newly discovered called Pellino3 acts by blocking obesity-driven , preventing resistance and diabetes.

The study directly correlated Pellino3 levels and abdominal fat tissue levels in individuals. Obese individuals had extremely low levels of Pellino3 , whereas lean individuals had a high amount. The lower levels of Pellino3 are associated with the production of a critically important pro-inflammatory called IL-1 that drives and ultimately diabetes.

“After nearly three years of research we have identified a new regulatory mechanism for controlling diet-induced diabetes by highlighting a critical role for ‘Pellino3” in regulating , said Professor Moynagh, the senior . “The identification of this new role for Pellino3 is an extremely exciting breakthrough and one that could have important implications for the fight against diseases such as ,” Prof Moynagh said. “My hope is that we can now build on this research and attempt to understand how we may be able to control or manipulate the Pellino3 as a method of preventing diabetes disease amongst those at .”
