This magic protein, Transforming Growth Factor Beta 2 or TGFbeta2, appears in both humans and mice as the result of exercise.  It controls blood sugar levels and neutralizes the effect of a high fat diet which in mice and in many humans induces diabetes. Your muscles do play a role in the process too.  The lactic acid they produce as you exercise appears to be the trigger that leads to TGFbeta2 release from fat.  The investigators speculate that, someday, this key protein messenger released by fat may become a practical treatment for diabetes. #fat #adiposetiss
