The medical applications of glucagon-like peptide-1 receptor (GLP-1R) agonists is evergrowing in scope, highlighting the urgent need for a comprehensive understanding of the mechanisms through which GLP-1R activation impacts physiology and behaviour. A new area of research aims to elucidate the role GLP-1R signalling in glia, which play a role in regulating energy balance, glycemic control, neuroinflammation and oxidative stress. Once controversial, existing evidence now suggests that subsets of glia (e.g. microglia, tanycytes and astrocytes) and infiltrating macrophages express GLP-1Rs. In this review, we discuss the implications of these findings, with particular focus on the effectiveness of both clinically available and novel GLP-1R agonists for treating metabolic and neurodegenerative diseases, enhancing cognition and combating substance abuse.
