Erythrocyte glutathione (GSH) can be rapidly depleted by incubating the cells with 1-chloro-2,4-dinitrobenzene (CDNB), which forms 2,4-dinitrophenyl-S-glutathione with GSH through the reaction catalyzed by glutathione S-transferase. GSH-CDNB conjugate thus formed stays undegraded within the erythrocytes. This indicates that in the

Human thioredoxin reductase is a dimeric enzyme that catalyzes reduction of the disulfide in oxidized thioredoxin by a mechanism involving transfer of electrons from NADPH via FAD to a redox-active disulfide. 1-Chloro-2,4-dinitrobenzene (DNCB) is an alkylating agent used for depleting

Cone of Pinus densiflora (CP), or Korean red pinecone, is a cluster of Pinus densiflora fruit. CP has also been verified in several studies to have anti-oxidation, anti-fungal, anti-bacterial, and anti-melanogenic effects. However, anti-inflammatory effects have not yet been confirmed

We previously reported that prior nasal administration of highly attenuated Bordetella pertussis BPZE1 provides effective and sustained protection against lethal challenge with influenza A viruses. The protective effect was mediated by suppressing the production of major pro-inflammatory mediators. To further
