They also produce high levels of proinflammatory chemicals that are linked to the development of obesity-associated insulin resistance.

In the new study, the researchers tested the idea that killing those cells would reverse the inflammatory symptoms that come with obesity using a mouse model developed earlier in which the CD11c-expressing macrophages were artificially made susceptible to diphtheria toxin.

They found that treatment with the toxin not only reversed the animals' resistance to insulin, but also led to a marked decline in inflammatory signs through the body. The treated animals showed a decline in the CD11c macrophages in both fat and muscle.

" It shows that high triglycerides in muscle don't necessarily have to lead to insulin resistance as it has been thought-as long as the high lipid levels aren't accompanied by inflammation," Neels said.

The obese mice also had less fat in their livers, an important find given the epidemic of obesity-associated fatty liver disease.

Neels said that if a unique marker can be identified on the macrophages found in human fat tissue, a drug could be designed to take advantage of those features to bind and kill them,

The study is published in the October Cell Metabolism, a publication of Cell Press.
