摘要：

L-Theanine (LTA), a non-protein-derived amino acid, is isolated from tea and is used as dietary supplement or beverage ingredient. This study established an enterotoxigenic Escherichia coli (ETEC)-infected mouse model of oxidative stress to examine the antioxidative mechanisms of LTA in vivo. LTA regulated non-enzymatic antioxidative activity and increased catalase (CAT) mRNA expression in non-ETEC-infected mice. In addition, LTA decreased oxidative parameters and the activity and mRNA levels of CAT in ETEC-infected mice. LTA increased superoxi...
