Women are more frequently affected by autoimmune diseases

Autoimmune diseases, such as type 1 diabetes and rheumatoid arthritis, affect one in five people worldwide. These conditions occur when the immune system mistakenly attacks its own tissues, leading to tissue destruction due to an inflammatory reaction. In recent years, autoimmune diseases have become more prevalent due to advancements in diagnostics and an increase in the average age of the population.

Western lifestyles and environmental changes are also believed to contribute to the rise of autoimmune diseases. Typically, these conditions begin in middle age and affect up to 80 percent of those affected are women. The reason for this gender discrepancy is unknown, but research suggests that estrogen may play a role in predisposing women to autoimmune diseases.

Recent studies led by Stanford University’s Diana Down have found that women’s susceptibility to autoimmune attacks may be linked to mechanisms on the X chromosome, specifically related to the silencing of one of the X chromosomes in women. The X chromosome is silenced by a molecular cover formed by xist-RNA strands that wrap around the DNA and proteins attached to them. Researchers found that this silencing mechanism may lead to autoimmune attacks in women by disrupting the balance between self and non-self recognition, making it harder for immune cells to recognize self-antigens as harmless and avoid attacking them.

Understanding the role of xist protein strands in autoimmune diseases can lead to early identification through autoantibody testing. Autoantibodies are often present before symptoms become apparent, making them valuable markers for diagnosis. This research highlights the importance of studying autoimmune diseases in both men and women to fully understand the underlying mechanisms at play and develop better treatment options.
