  • 摘要:Selenium (Se) is a micronutrient that is incorporated into proteins. Some of the selenoenzymes such as GPXs and thioredoxin reductases exhibit glutathione peroxidase-dependent activities towards organic and inorganic peroxides. Thus, selenoenzymes play a pivotal role in mitigating oxidative stress caused by accumulation of peroxides. In this respect, selenoproteins may interfere with the transcription-driven by oxidative stress-dependent signaling mechanisms to influence the expression of redox sensitive genes, including inflammatory cytokines and HIV provirus. Several epidemiological studies support our view that Se supplementation affects transcription of HIV; however, the underlying mechanism is not elucidated. In this mini review, we consider the relationship between Se and HIV and propose possible mechanisms by which Se controls HIV transcription.
