Background: The mechanisms of action of dimethyl fumarate (DMF), and its metabolite, monomethyl fumarate (MMF), for the treatment of multiple sclerosis are not completely elucidated. Objectives: To discuss the role of DMF/MMF-induced hydroxycarboxylic acid receptor 2 (HCA(2)/GPR109A) pathway activation in the immune response and treatment of MS. Methods: A narrative (traditional) review of the current literature. Results: Studies have shown that binding of DMF/MMF to HCA(2) on dendritic cells inhibits the production of proinflammatory cytokines in vitro and in MS murine models. Evidence suggests that activation of HCA(2) expressed in immune cells and gut epithelial cells by DMF/MMF, may induce anti-inflammatory responses in the intestinal mucosa. Conclusion: Although the DMF/MMF mechanism of action remains unclear, evidence suggests that the activation of HCA(2)/GPR109A pathway downregulates the immune response and may activate anti-inflammatory response in the intestinal mucosa, possibly leading to reduction in CNS tissue damage in MS patients.
