The influence of type I interferons on immune cells can be mediated through regulation of estrogen receptor alpha level
Anna Chełmońska-Soyta , T. Maj
Autoimmune disorders are connected with the actions of sex hormones. Clinical observations have shown that especially estrogens are involved in these phenomena. In some cases the administration of estrogens can increase the pathological symptoms of a disorder, while in others they can cause disease remission. In multiple autoimmune diseases, type I interferons, a family of cytokines acting through the common receptor IFNAR1/IFNAR2, seem to have action convergent with that of estrogens. We hypothesize that this coincidence is not accidental and type I interferons can regulate the level of estrogen receptor alpha (ERα) and consequently change the sensitivity of immune cells to estrogen's action. There is evidence that ERα is responsible for the effects exerted by estrogens and that this phenomenon mainly involves antigen-presenting cells. On the other hand, research on IFN-tau, a type I interferon family members, showed that this cytokine can modulate ERα levels in ovine endometrium. Because of the common receptor for these interferons, we suspect that other type I interferons can act in this way not only in endometrial cells, but also in immune cells. If there is such a mechanism, it can be exploited in the therapy of immune disorders, especially autoimmune disease, for example through simultaneous administration of less toxic interferons and estrogens. © 2008 Elsevier Ltd.
