Representative studies showing CO-dependent protection in inflammation models.
Injury/Disease Model | Species | Dose | Observation | Ref. |
---|---|---|---|---|
LPS | Mice | 250 ppm [100–500 ppm] CO | Anti-inflammatory effect, reduction of pro-inflammatory cytokines (TNFα, IL-6), p38 MAPK, JNK, IL-6 dependent. Upregulation of serum IL-10. |
