Inflammation protein linked to obesity in women
Women with a certain protein, called allograft inflammatory factor (AIF-1) may be more likely to be obese, according to new research.
Previous studies have shown that this protein is normally activated by white blood cells when the body is injured and helps heal the body through inflammation.
Researchers from Sweden conducted studies on body fat samples from women who were obese and women who were not, in order to determine the role of AIF-1 in female fat tissue.
The results, published in the journal BMC Endocrine Disorders, showed that AIF-1 was secreted by fat tissue. Women who were obese were found to have higher levels of AIF-1 than women who were not obese.
While the findings suggest that the protein AIF-1 is regulated by changes in body fat mass, researchers said it is unclear whether the protein actually manipulates fat cells or whether it is simply a marker for obesity.
