Epidemiological and case-controlled studies suggest that estrogen replacement therapy might be beneficial in terms of primary prevention of coronary heart disease (CHD). This beneficial effect of estrogens was initially considered to be due to the reduction of low density lipoproteins (LDL) and to increases in high density lipoproteins (HDL). Recent studies have shown that estrogens protect aga...
In addition to exerting genomic actions via nuclear receptors within hours to days, estrogens also regulate neuronal activity much faster (within seconds) by activating neuronal membrane receptors coupled to intracellular second-messenger pathways. To date, the origin of estrogens inducing rapid effects in the brain remains unclear, although it is often ascribed to the gonads. We report here th...
Estrogens are a broad class of compounds which exert many physiological effects. In addition to gonadal and peripheral endogenous estrogen production, humans can be exposed to exogenous estrogenic compounds (xenoestrogens) from medicinal, dietary and environmental sources. These compounds can exert effects similar to that of 17 -estradiol (E2) through estrogen receptor (ER)-mediated mechanisms,...
