New research on mice has found a possible explanation for why autoimmune diseases are more common in females, and it has to do with their extra X chromosome.

對老鼠進行的新研究，可能解釋了為何女性更常出現自體免疫性疾病，這與她們多出的一條X染色體有關。

Amongst animals, females generally tend to have stronger and more robust immune systems. While this can help them to cope better with vaccines and infections, it can also cause an overactive immune response.

在動物中，雌性往往有更強大的免疫系統。雖然這可以幫助她們更好地應付疫苗和感染，但也可能會導致過度免疫反應。

This means females are much more vulnerable to autoimmune diseases.

這意味著女性更容易罹患自體免疫性疾病。

Exactly why this discrepancy exists remains a mystery. Clear biological differences between the sexes usually boil down to hormones, chromosomes, or some combination of both. But while the role of testosterone, estrogen and progesterone in autoimmunity have been reasonably well explored, the part that X and Y chromosomes play remains far more murky.

存在這種差異的確切原因，仍然是個謎。兩性之間明顯的生物學差異，通常可歸結為荷爾蒙、染色體或兩者的某種結合。雖然人們已經對睪酮、雌激素和黃體酮在自體免疫中的作用進行適度探索，但X染色體和Y染色體的作用依然不明。
