The role of estrogen receptors in B cell mediated autoreactivity
Since SLE affects females almost 10 times more frequently than males, it has been widely speculated that estrogen plays a role in disease progression. To learn more about the effects of estrogen in SLE patients, Dr. Grimaldi has been treating mice with estrogen. The data accumulated have shown that an increase in estrogen induces a lupus-like disease in mice, indicating that elevations of estrogen levels are sufficient to alter the regulation of autoreactive B cells. Her ANRF study will focus on estrogen receptors, trying to determine the effects of different receptors on the survival and activation of autoreactive B cells. This may have important clinical applications: selective estrogen receptor modulators could be developed to counteract the estrogen receptor identified as integral for progression of SLE.
