The balance between neuronal apoptosis and survival sculpts the developing brain and has an important role in neurodegenerative diseases. Thus, the individuation of signals that could modulate the cell death machinery as well as enhance survival in neurons promises to provide multiple points of therapeutic intervention in neurodegenerative diseases. Neuroglobin (NGB), the first nerve globin identified in neuronal tissues of humans, seems to possess a protective role in the brain only after up-regulation. ⋯ As a consequence, a decrease of caspase-3 activation and, in turn, of the apoptotic cascade activation take place. Besides E2, other compounds have been reported to up-regulate the NGB expression highlighting the possibility to develop NGB-mediated therapeutic strategies against stroke damage and neurodegenerative diseases.
