Research Summary

The Molecular Basis of Neurodegeneration and Therapeutic Strategies.
Research is geared toward unraveling the molecular basis of neurodegeneration and devising therapeutic strategies to hamper the processes that cause neuronal death. To that end, we have concentrated our research efforts on the MPTP mouse model of Parkinson's disease (PD) and on the mutant superoxidedismutase-1 (mSOD1) mouse model of amyotrophic lateral sclerosis (ALS). Work in our laboratory has demonstrated that following the administration of the neurotoxin MPTP, the demise of the nigral dopaminergic neurons (the hallmark of PD) depends on the production of the reactive species, nitric oxide (NO), which originates in neighboring neurons and glial cells.
We have also shown that NO does not cause damage directly, but rather by reacting with another reactive species superoxide to produce peroxynitrite - the actual culprit. We have shown that peroxynitrite, once produced, inflicts severe damage on cell proteins and DNA. Cell death is likely to result not only from these injuries, but also from apoptosis. Apoptosis, which is a form of programmed cell death, also appears to play a major role in the degeneration of spinal cord motor neurons in ALS. This view is supported by several recent publications from our laboratory. For example, the expression of key molecular apoptotic factors is altered in transgenic mSOD1 mice in a way that promotes cell death.

Through genetic and pharmacological interventions aimed at alleviating these noxious changes, one of our teams was able to prolong survival and attenuate neuronal death in this mouse model of ALS. This beneficial effect is, in part, mediated by the prevention of the release of cytochrome c from the mitochondria, which triggers a cascade of deleterious events implicated in the death of motor neurons.
