Abstract

Growing interest in the role of oligodendrocytes in psychiatric disorders has been noted. The main function of oligodendrocytes is related to neuronal myelination, and damage in the myelination affects the action potentials and consequently the connectivity between different brain regions. In this regard, studies have investigated the effect of pharmacological tools on mature oligodendrocytes and their precursor cells to understand the pathological processes of demyelination, and to discover possible therapeutic agents for this process. Studies indicate that the modulation of the endocannabinoid system in oligodendrocytes can affect important biological processes. Thus, the aim of this project will evaluate several pharmacological manipulations of the endocannabinoid system in human culture of oligodendrocytes (MO3.13), and in the differentiation process of these cells. These investigations may elucidate aspects of disorders with demyelinating processes, such as multiple sclerosis and schizophrenia. More specifically, studies have shown the involvement of the endocannabinoid system and oligodendrocytes in the pathophysiology of this schizophrenia. Thus, we will investigate the possible relationships between these two components. For this, MO3.13 culture cell will be treated with MK801 (NMDAr antagonist), which has been an in vitro model to study schizophrenia proposed by our group. We hope to identify the proteins and biochemical pathways affected by cannabinoids in immature and mature cells treated or not with MK801, as well as the influence on the differentiation process. For this, proteomic and molecular biology will be used. Finally, this study may contribute to the understanding of the role of the endocannabinoid system in oligodendrocytes and the possible implications for elucidating aspects of the pathophysiology of the demyelinating process and more specifically in the context of schizophrenia.
