Abstract

Abstract : The nuclear factor erythroid 2 related factor 2 (Nrf2) is a major regulator of intracellular inducible defense systems against harmful endogenous and exogenous substances in the body. Under normal conditions Nrf2 is mainly binds to keap1 and located in the cytoplasm. However, in response to oxidative and electrophile stress, Nrf2 translocated to the nucleus and link to anti‐oxidant response elements to induce the transcription of cytoprotective genes. Most viruses cause oxidative stress and increase the activity of radicals and reactive oxygen species (ROS), subsequently, the cellular protection system activates the Nrf2 and increases the expression of cytoprotective genes. However, in some cases, the activation of Nrf2 is not ROS‐dependent, and is carried out directly via the ROS‐independent pathway. Many viruses cause the activation of Nrf2, which is involved in the pathogenesis and the progression of the virus infection and even in its chronic form. However, some viruses inhibit the activation of Nrf2, in which case the virus also benefits of this mechanism to maintain the homeostasis of the cell. However, the challenge between the Nrf2/ARE signaling pathway of and viral infections is unknown in some cases, and in order to know more details in this regard, a more detailed seems necessary.
