Neuroactive steroid family includes steroid hormones produced in peripheral glands and steroids directly synthesized in the nervous system (i.e., neurosteroids).These molecules, by mechanisms involving classical and/or non classical steroid receptors, act as important physiological regulators of nervous function, affecting mood, behavior, reproduction and cognition, as well as acting like protective agents in models of injury, neurodegenerative diseases and psychiatric disorders.
As reported, neuroactive steroid levels in central and peripheral nervous system are sex dimorphic and are influenced by hormonal environment. Moreover, data obtained in experimental models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, peripheral neuropathy, psychiatric disorders etc. have shown that pathological conditions also alter the levels of neuroactive steroids and in some cases these changes occur in a sex-dimorphic way. Altogether, these observations may represent a background for possible neuroprotective strategies based on neuroactive steroids to be to be applied in human diseases.

I nostri giovani ricercatori aggiornano i colleghi sulle loro ricerche. Appuntamento ogni due venerdì.
Il nostro gruppo di ricerca guidato da Luca Bonfanti ha individuato una riserva di neuroni “immaturi” in zone inedite del cervello: si aprono nuovi scenari per compensare la scarsa capacità del cervello di rigenerarsi. Lo studio è stato pubblicato sul Journal of Neuroscience di dicembre.
