Nrf2 could have a protective role in many autoimmune diseases (i.e., vitiligo, asthma, multiple sclerosis, and systemic lupus erythematosus) since an increased production of reactive immunogenic macromolecules intermediates in these disorders seems closely linked to the loss of several phase II detoxification enzymes regulated by the activation of Nrf2 genes [23,36]. Here, NFE2L2 is linked to systemic lupus erythematosus.
