As homeostatic regulators of brain function, some hormones exert neuroprotective actions. This is the case for the ovarian hormone 17β‑oestradiol, which signals through oestrogen receptors (ERs) that are widely distributed in the male and female brain. Recent discoveries have shown that oestradiol is not only a reproductive hormone but also a brain-derived neuroprotective factor in males and females and that ERs coordinate multiple signalling mechanisms that protect the brain from neurodegenerative diseases, affective disorders and cognitive decline.engjournal articlehttp://www.nature.com/nrn/index.htmlrestricted access576612.433Biología CelularHormonas17β‑oestradiolCitologíaBiología celular (Biología)2407 Biología Celular
