Scientists have found that mice lacking a protein known as SH2B1 throughout their body are obese and ultimately develop diabetes. Researchers replaced SH2B1 in the brain of obese mice and it seemed to deter the onset of obesity. The study reveals that targeting SH2B1 in the brain might be a new avenue of treatments for obesity and type 2 diabetes.
SH2B1 is expressed in tissues related to obesity, including the brain, liver, pancreas, and fat tissue. Replacing SH2B1 in the brain of mice lacking SH2B1 prevented the mice from becoming obese. It also prevented the mice from developing obesity after being fed a high-fat diet, indicating that SH2B1 in the brain is required to regulate body weight and fat content.
This study implies that SH2B1 in the brain is a practical target for the development of new drugs to treat obesity and type 2 diabetes.
