Neurotrophic factors, and especially the neurotrophins, are proteins known to play a key role in neuronal repair, maintenance and differentiation as well as to model our neuronal circuitry. Therefore, neurotrophins are essential to our ability to move, feel and think. The primary focus of Dr. Mocchetti’s research program at Georgetown University is to study the neurobiology of the neurotrophins. The ultimate goal of such program is to use these proteins as potential biotherapies for human neurological disorders, such as Alzheimer’s and Parkinson’s diseases, stroke, trauma and AIDS dementia. Specifically, Dr. Mocchetti’s group is characterizing the neuroprotective effects of a major neurotrophin, Brain-Derived Neurotrophic Factor (BDNF). Using neuronal cultures, viral vectors and mutant mice, they have recently demonstrated that BDNF reduces neuronal cell death evoked by HIV-1 proteins, most likely by down-regulating chemokine receptors responsible for mediating viral neurotoxicity.  Based on these results, Dr. Mocchetti’s group is currently studying synthetic compounds that mimic the neurotrophic effect of BDNF while being able to cross the blood brain barrier (BBB).  Using transfected cell lines and technique probing different signal transduction pathways, his group has recently demonstrated that gangliosides, compounds able to cross the BBB, indeed mimic the neurotrophic effects of the neurotrophins. These exciting results raise a legitimate hope that gangliosides and potentially other compounds yet to be identified could be used as therapeutic tools in neurodegenerative diseases.

‘Cold Turkey’ Withdrawal Triggers Mental Decline in Animals


“’From these findings, it appears that morphine withdrawal may be a causative factor that leads to mental decline, presenting an important avenue for research in how we can better help people who are trying to quit using drugs,’ Mocchetti says.”

HIV Reveals General Theory of Dementia


“‘This finding is extremely important for both basic scientists and physicians, because it suggests a new avenue to understand, and treat, a fairly widespread cause of dementia,’ Mocchetti says.”
