Autoimmunity is influenced by multiple factors including gender and sex hormones. A definite female predominance is found in many autoimmune diseases. Gender is also associated with differences in clinical presentation, onset, progression and outcome of autoimmune diseases. Sex hormones might influence the target organ's vulnerability to an autoimmune response. Gender differences also exist in organ specific autoimmune diseases such as multiple sclerosis, Guillain-Barre syndrome, Crohn's disease and celiac disease. Nevertheless, other organ specific autoimmune diseases (i.e. ulcerative colitis) are seemingly characterized with similar prevalence in both males and females. The reason for gender differences in certain autoimmune diseases remains unknown, but may be attributed to sex hormone influence, fetal microchimerism, X chromosome inactivation, and X chromosome abnormalities. Sex hormones have been found to have immune modulating properties, as well as providing cellular protection following tissue damage in certain circumstances. Sex hormones also influence innate and adaptive immune cells, number of B and T cells, antigen presentation and cytokine secretion. Herein, we review the influence of gender on organ-specific autoimmune diseases affecting the heart, blood vessels, central nervous system and gastrointestinal tract. It appears that sex hormones may have a therapeutic potential in several autoimmune conditions, although further research is required before therapeutic recommendations can be made.
