[Research progress on macrophage metabolic reprogramming in ocular diseases]

Area of Science:

• Immunology
• Cellular Metabolism
• Ocular Disease Research

Background:

• Macrophages are vital immune cells with significant plasticity, crucial for host defense and homeostasis.
• Metabolic reprogramming, the adjustment of cellular metabolism, critically influences macrophage phenotypes and functions.
• Metabolism provides energy and building blocks for macrophages, and its byproducts regulate gene expression and signaling.

Purpose of the Study:

• To review the immunomodulatory roles of key enzymes and metabolites in major macrophage metabolic pathways.
• To highlight advancements in targeting macrophage metabolic regulation for ocular diseases.

Main Methods:

• Literature review focusing on metabolic reprogramming in macrophages.
• Analysis of key enzymes and products in glucose, lipid, and amino acid metabolism.
• Examination of therapeutic strategies targeting macrophage metabolism in ocular conditions.

Main Results:

• Metabolic reprogramming is central to macrophage polarization and function.
• Specific metabolic pathways (glucose, lipid, amino acid) significantly impact macrophage immunomodulation.
• Targeting metabolic pathways shows promise for treating ocular diseases.

Conclusions:

• Macrophage metabolic reprogramming is a critical regulator of immune responses.
• Understanding these metabolic pathways offers therapeutic opportunities, particularly in ocular disease management.
