Since the publication of the 1998 special issue of Hormones and Behavior on estrogens and cognition, substantial progress has been made towards understanding the molecular mechanisms through which 17 beta-estradiol (E-2) regulates hippocampal plasticity and memory. Recent research has demonstrated that rapid effects of E-2 on hippocampal cell signaling, epigenetic processes, and local protein synthesis are necessary for E-2 to facilitate the consolidation of object recognition and spatial memories in ovariectomized female rodents. These effects appear to be mediated by non-classical actions of the intracellular estrogen receptors ER alpha and ER beta, and possibly by membrane-bound ERs such as the G-protein-coupled estrogen receptor (GPER). New findings also suggest a key role of hippocampally-synthesized E-2 in regulating hippocampal memory formation. The present review discusses these findings in detail and suggests avenues for future study. (C) 2015 Elsevier Inc. All rights reserved.
