Scientists have spotted unique subtypes of fat cells in the human body.

By unraveling their functions, they found that the cells may play a role in obesity.

The research could theoretically open up avenues for new therapies to mitigate downstream effects of obesity.

Visceral fat — fat cells that reside in the abdomen close to the internal organs — is linked to a greater risk of health problems.

If these fat subtypes can be linked to human disease, understanding how they work could "help us fight inflammatory processes," Yeger-Lotem said.

That could potentially help doctors predict the risk of insulin resistance in people with obesity.

Berry cautioned that the study used a relatively small sample size and that, at this stage, it only suggests rather than definitively demonstrates that the fat cells have unusual functions.
