“…In addition, the loss of estrogen or its receptors early in the life of experimental mouse models of SLE has provided convincing evidence showing that estrogens have an important role in the development and progression of the disease (5, 35, 43). Surprisingly, the contribution of estrogens to SLE disease progression in humans remains unclear, and understanding their role in the cardiovascular risk is complicated by the large body of literature pointing to cardioprotective actions of estrogens in women (22, 47) as well as their relatively safe use in women with SLE (3,7,8,20,26,31,40). Using an established experimental model of SLE (female NZBWF1 mice), we (12) recently reported that loss of estradiol in adulthood exacerbates the hypertension and renal injury, which, when considering that loss of estrogens early in life delays disease onset, suggests that there are distinct temporal effects of estrogens on SLE disease progression and its consequences.…”
