The neuroactive steroids dehydroepiandrosterone (DHEA), its sulfate ester DHEA sulfate (DHEAS), and allopregnanolone (Allo), produced by the CNS and the adrenals, appear to exert a protective effect in hippocampal and cortical neuron ischemia- and excitotoxicity-induced injury. We hypothesized that they may also play a protective role on the adrenal(More)
Experimental and epidemiological data suggest a neuroprotective role for estrogen (E(2)). We have recently shown that, in PC12 cells, non-permeable estradiol conjugated to bovine serum albumin (BSA) prevent serum-deprivation induced apoptosis through activation of specific membrane estrogen receptors (mER). In the present study, we explored in detail the(More)
The neuroprotective role of estrogen (E2) is supported by a multitude of experimental and epidemiological data, although its mode of action is not fully understood. The present work was conducted to study the underlying mechanisms of its neuroprotective action, using the rat cell line PC12, an established model for neuronal cell apoptosis and survival. Our(More)
