Glycolysis - a key player in the inflammatory response

Area of Science:

• Immunology
• Cellular Metabolism
• Biochemistry

Background:

• Inflammation is a critical immune response involving diverse cell types to combat threats and maintain tissue homeostasis.
• Pro-inflammatory cells (M1 macrophages, Th1/Th17 lymphocytes, microglia) require rapid energy via glycolysis and lactate production.
• Anti-inflammatory and regulatory cells (M2 macrophages, regulatory T cells) utilize fatty acid oxidation and the TCA cycle for energy.

Purpose of the Study:

• To discuss the impact of glycolytic metabolism on inflammatory response steps.
• To review molecular mechanisms linking glycolytic metabolites to pro-inflammatory phenotypes.
• To highlight immunometabolism as a potential therapeutic target for inflammation-related diseases.

Main Methods:

• Literature review focusing on cellular metabolism in inflammation.
• Analysis of molecular mechanisms connecting metabolites to inflammatory cell function.
• Exploration of therapeutic implications of immunometabolism.

Main Results:

• Glycolysis is crucial for fueling pro-inflammatory responses.
• Fatty acid oxidation supports immune regulation and inflammation resolution.
• Molecular pathways including signaling, epigenetics, and post-translational modifications link metabolism to inflammation.

Conclusions:

• Cellular metabolism, particularly glycolysis, plays a pivotal role in regulating inflammatory processes.
• Understanding immunometabolism provides novel strategies for treating age-associated inflammatory diseases.
• Targeting immune cell metabolism offers a promising therapeutic avenue for inflammatory pathologies.
