Monocyte-derived cells (MCs) are essential for managing central nervous system (CNS) inflammation. Consequently, understanding monocyte metabolism in CNS pathology is now a major research priority. Local signals such as oxygen levels and nutrient availability shape the metabolic state of these cells. Consequently, their functional state is far more complex than the traditional M1/M2 framework.
Research shows that glycolysis, oxidative phosphorylation, and lipid metabolism govern how MCs perform specific tasks. For instance, glycolytic pathways typically support the production of pro-inflammatory cytokines. On the other hand, oxidative phosphorylation often fuels reparative functions like phagocytosis and efferocytosis. Thus, the metabolic state of these cells directly determines the progression of sterile injury and demyelinating diseases.
Additionally, this metabolic programming is critical during viral encephalitis. Because the immune response can cause significant tissue damage, metabolic modulation offers a precise way to control inflammation. Furthermore, targeting these internal pathways allows for therapeutic intervention without compromising the entire immune system. In conclusion, integrating immunometabolism into neuroinflammation research provides a robust framework for future treatments.
Glycolysis serves as a primary energy source that fuels rapid pro-inflammatory responses, including the production of cytokines during acute phases of CNS disease.
The metabolic state of monocyte-derived cells is shaped by local cues such as oxygen availability, nutrient levels, and the presence of inflammatory or anti-inflammatory signals.
