Science, 1993•science.orgTumor necrosis factor-α (TNF-α) has been shown to have certain catabolic effects on fat cells
and whole animals. An induction of TNF-α messenger RNA expression was observed in
adipose tissue from four different rodent models of obesity and diabetes. TNF-α protein was
also elevated locally and systemically. Neutralization of TNF-α in obese fa/fa rats caused a
significant increase in the peripheral uptake of glucose in response to insulin. These results
indicate a role for TNF-α in obesity and particularly in the insulin resistance and diabetes …
