Luteolin and hormesis

The present paper provides the first integrated assessment of the capacity of luteolin to induce hormetic dose responses. It was shown that luteolin induced hormetic responses in multiple biological systems, including enhancing neuroprotection in various experimental model disease systems, improving wounding healing, especially in experimental models of high-risk population subgroups, such as diabetics, as well as enhancing osteogenesis in models of osteoporosis. The mechanistic basis for the luteolin-induced hormetic dose responses has been demonstrated to commonly involve the upregulation of the nuclear factor erythroid-derived 2-like 2 (Nrf2), which mediates the extensive range of anti-inflammatory effects induced by luteolin in multiple cell types and organ systems.

Automated summary

This study demonstrates that luteolin can induce hormetic dose responses in various biological systems, exerting beneficial effects on neuroprotection, wound healing, and osteogenesis. The mechanism behind these responses is mainly attributed to the upregulation of Nrf2, which mediates the anti-inflammatory effects induced by luteolin in different cell types and organ systems.
