Glia function in the endocanabinoid system: narrative review
Função da glia no sistema endocanabinoide: revisão narrativa
José Osvaldo Barbosa Neto; João Batista Santos Garcia
Abstract
BACKGROUND AND OBJECTIVES: Evidence has highlighted a role of glial cell activation, and their interaction with different neural systems, especially the endocannabinoid system, in the mechanisms involved in the chronicity and maintenance of pain. The aim of this review is to bring an update on published data that demonstrate the interaction between glial cells and the endocannabinoid system in the pathophysiology of chronic pain and its treatment.
CONTENTS: A narrative review was performed based on a research in the Medline database, using the keywords “endocannabinoid”, “glial cells”, “microglial”, “astrocytes”, “neuroinflammation”.
CONCLUSION: Deepening the knowledge about the function of glial cells in the endocannabinoid system will open the possibility of acting on the pathophysiological origin of the pain chronification process, attenuating the mechanisms involved in central sensitization.

Resumo
JUSTIFICATIVA E OBJETIVOS: A evidência científica tem ressaltado um papel da ativação das células da glia e de sua interação com diversos sistemas neurais, com destaque para o sistema endocanabinoide e mecanismos envolvidos na cronificação e manutenção da dor. O objetivo deste estudo foi atualizar os dados publicados que mostrem a interação entre as células da glia com o sistema endocanabinoide na fisiopatologia da dor crônica e seu tratamento.
CONTEÚDO: Foi realizada uma revisão narrativa baseada em pesquisa na base de dados Medline, com uso dos unitermos “endocannabinoid”, “glial cells”, “microglial”, “astrocytes”, “neuroinflammation”.
CONCLUSÃO: O aprofundamento do conhecimento acerca da função das células da glia no sistema endocanabinoide abrirá a possibilidade de atuação sobre a origem fisiopatológica do processo de cronificação de dor, atenuando os mecanismos envolvidos na sensibilização central.
