Abstract

Modafinil is a psychostimulant drug approved for the treatment of excessive daytime sleepiness, narcolepsy, shift work, and sleep apnea. Among the documented but not yet approved uses for modafinil, it was reported as presenting potential therapeutic uses in ADHD, depression, cocaine dependence, schizophrenia, obesity and fatigue in neurodegenerative diseases. Several studies in rodents described the behavioral and neurochemical changes resulting from modafinil treatment, mainly through modulation of dopaminergic and noradrenergic systems. Recent findings have reported that this drug has neuroprotective potential in animal models of neuroinflammation. However, the mechanism of the neuroprotective effect of modafinil as well as the effect of this drug on the peripheral and CNS immune response are still unknown. Thus, the aim of this study is to evaluate, in mice, the effects of treatment with modafinil on peripheral immunity, neuroinflammation and development of experimental autoimmune encephalomyelitis (EAE), the murine model of Multiple Sclerosis. Specifically, we will analyze the phenotype and cytokine production by in vitro peripheral cells and the in vivo response to delayed-type hypersensitivity, the in vitro immune-inflammatory response of CNS cells, as well as the development of clinical symptoms and characterization of infiltrating inflammatory cells during EAE. We also intend to study the role of different cell types involved in the effect of modafinil in the periphery (lymphocytes vs APCs) and CNS (microglia vs astrocytes), as well as the involvement of dopaminergic, noradrenergic and cholinergic receptors in the phenomenon, through the pharmacological blockade of these receptors. Data will be analyzed under a neuroimmune perspective, specifically the interaction among immunity, dopamine and the neurodegenerative diseases, and possibly they may contribute to suggest therapeutic alternatives.
