The Claim

In obese mice on a high-fat diet, biliverdin treatment reduces adipose tissue expression of the proinflammatory cytokine TNF-α and the M1 macrophage marker Cd11c, but does not significantly alter M2 macrophage markers or adiponectin levels.

How it works
1 study reviewed
In plain English

In obese mice fed a high-fat diet, biliverdin lowers the levels of TNF-α and Cd11c in fat tissue but does not change levels of M2 macrophage markers or adiponectin.

See the scientific wording

In obese mice on a high-fat diet, biliverdin treatment reduces adipose tissue expression of the proinflammatory cytokine TNF-α and the M1 macrophage marker Cd11c, but does not significantly alter M2 macrophage markers or adiponectin levels.

Why this might work

When biliverdin enters fat tissue, it turns into bilirubin, which blocks the production of harmful reactive molecules by stopping a key enzyme complex. This reduction in reactive molecules lowers inflammation signals in fat, causing immune cells called macrophages to switch from a pro-inflammatory state to a less active one. As a result, the fat tissue releases less of the inflammatory protein TNF-alpha and fewer M1 macrophage markers, while anti-inflammatory signals remain unchanged.

  1. Study: Bilirubin reduces visceral obesity and insulin resistance by suppression of inflammatory cytokines

    In obese mice, giving biliverdin lowered harmful inflammation signals in fat tissue (TNF-α and Cd11c) but didn’t change the helpful signals (like adiponectin or M2 markers), just like the claim says.
