Autoimmune disorders, redox balance and gender differences are closely connected. In fact, activation, proliferation and death of cells of different histotype, including blood and vascular cells, are under control of oxidative balance and are key players in autoimmune disease pathogenesis and progression. However, cells from male and female appear characterized by a huge series of differences in terms of reactive oxygen species production and oxidative stress susceptibility. In this review, we briefly summarize the possible implications of the redox state in the onset and progression of autoimmune diseases in a gender perspective.
