The neuroprotective actions of oestradiol and oestrogen receptors

Recent discoveries have shown that both hormonal and brain-derived oestradiol have neuroprotective effects. This Review provides a comprehensive review of the multiple cell types, receptors and signalling cascades that underlie oestradiol-mediated neuroprotection. Abstract Hormones regulate homeostasis by communicating through the bloodstream to the body's organs, including the brain. As homeostatic regulators of brain function, some hormones...
