….locally synthesized PROG are likely to play an important role in the viability of neurons and in the formation of myelin sheaths.
Local synthesis of PROG in the brain and the neuroprotective and promyelinating effects of this neurosteroid offer interesting therapeutic possibilities for the prevention and treatment of neurodegenerative diseases, for accelerating regenerative processes and for preserving cognitive functions during aging.
Our findings suggest that PROG enhancement of endogenous neuronal BDNF could provide a trophic environment within the lesioned spinal cord and might be part of the PROG activated-pathways to provide neuroprotection.
Among the family of steroidal molecules, only estrogens have the capability of preventing neuronal cell death caused by increased oxidative burden.
Thus, our view of the role of estrogen in neural function must be broadened to include not only its function in neuroendocrine regulation and reproductive behaviors, but also to include a direct protective role in response to degenerative disease or injury. Estrogen may play this protective role through several routes. Key among these are estrogen dependent alterations in cell survival, axonal sprouting, regenerative responses, enhanced synaptic transmission and enhanced neurogenesis.
An accumulating body of evidence clearly establishes that estradiol is a potent neuroprotective and neurotrophic factor in the adult
Although data from human studies remains highly controversial, a large body of research findings suggests that this hormone plays a pivotal role in retarding and preventing the formation of neurodegenerative diseases through its receptor.
This study demonstrates that activation of either ERalpha or ERbeta can result in neuroprotection and that activation of the MAPK pathway is an important part of the neuroprotective mechanism.
Using three indicators of neuronal viability and survival, we demonstrated that both the ERalpha selective agonist PPT and the ERbeta selective agonist DPN protected hippocampal neurons against glutamate-induced cell death in a dose-dependent manner,
As ERbeta is highly expressed in the brain and has little or no expression in the breast or uterus, discovery and design of ERbeta selective molecules could provide a strategy for activating the beneficial effects of estrogen in the brain without activating untoward effects of estrogen in reproductive organs.
