Abstract

Abstract - Characterized by severe motor dysfunctions resulting from the degeneration and death of dopaminergic (DA) neurons mainly from the substantia nigra (SN), Parkinson's disease (PD) is the second most common neurodegenerative disorder in developed countries. There is no cure or proven strategy for slowing the progression of this disease. Although the pathophysiological mechanisms of PD remain under investigation, there is little doubt of the involvement of cytosolic Ca2+ overload consequent to imbalance in intracellular Ca2+ homeostasis in the degeneration and death of DA neurons. Thus, the pharmacological modulation of intracellular Ca2+ signaling to attenuate the degeneration and death of DA neurons has become a promising neuroprotective strategy in PD therapy. Recent studies from our laboratory have shown that several cellular responses, such as neurotransmitter release and cellular survival, are regulated by the interaction of Ca2+ with other intracellular messenger systems, such as cyclic adenosine monophosphate (cAMP) and nitric oxide (NO), thus establishing a functional interaction of Ca2+/cAMP/NO intracellular signaling. In this way, we have proposed that the pharmacological modulation of this Ca2+/cAMP/NO signaling could importantly contribute to the development of new therapeutic strategies of neurodegenerative diseases, including PD. Based on this proposal, this research project aims to evaluate the neuroprotective effect stimulated by the pharmacological modulation of Ca2+/cAMP/NO intracellular signaling in animal model of PD.
