MPO and inflammation: In pulmonary inflammation caused by intratracheal LPS, EGCG alleviated lung injury and edema, decreased counts of inflammatory cells in the lung, decreased activities of myeloperoxidase (MPO) and proteinkinase Cα, lowered levels of TNFα, IL-1β, and IL-6 [260], and mitigated oxidative damage and enhanced lung regeneration [261].
