Abstract

The cannabinoid system has been implicated as an important neuromodulation system in several experimental models of neuronal injury both acute and chronic type, which many studies suggest a neuroprotective action. Parkinson's disease (PD), characterized by loss of dopaminergic neurons in the substantia nigra, yet its etiology is unknown. Nevertheless, several factors seem to be involved as mitochondrial dysfunction, oxidative stress, and neuroinflammation. Studies on the relations of the cannabinoid system and DP, however, are still very controversial, partly because the literature related to possible neuroprotective role of the cannabinoid system are still incipient. The overall objectives of this project are to investigate the involvement of cannabinoid system in an in vitro model of neurodegeneration, which evaluate the parameters of oxidative stress and neuroinflammation as a way to understand the contribution of each to the progression of neurodegenerative diseases generally and in particular PD and the role of the cannabinoid system. For this, we use a strain of neuroblastoma cells to be differentiated into dopaminergic and treated with different inducers of neuronal damage such as 6-OHDA, H2O2 and LPS conjugated to treatment with agonist and antagonist cannabinoids. Parameters will be assessed cell viability marker proteins in addition to oxidative stress, neuronal death and survival, by enzymatic methods, Western blot, immuno-cytochemical and PCR. (AU)
