[Immunometabolism and systemic lupus erythematosus]

Area of Science:

• Immunology
• Metabolic pathways
• Autoimmune diseases

Background:

• Systemic lupus erythematosus (SLE) is a complex autoimmune disease.
• Immune homeostasis is disrupted, leading to autoantibody production and organ damage.
• Immunometabolism significantly influences immune cell function and survival.

Purpose of the Study:

• To explore the role of immunometabolism in SLE pathogenesis.
• To identify specific metabolic abnormalities in immune cells involved in SLE.
• To investigate CD4+ T cells as key players in SLE immunometabolism.

Main Methods:

• Analysis of immunometabolic profiles in SLE patients and lupus mouse models.
• Examination of metabolic pathways in various immune cells, focusing on CD4+ T cells.
• Assessment of cellular functions, signaling pathways, and molecular changes.

Main Results:

• SLE patients and lupus models exhibit widespread immunometabolic abnormalities.
• CD4+ T cells in SLE show heightened glycolysis and oxidative phosphorylation.
• Mitochondrial dysfunction, increased oxidative stress, and altered lipid metabolism are observed in SLE CD4+ T cells.

Conclusions:

• Abnormal immunometabolism, especially in CD4+ T cells, is central to SLE pathogenesis.
• Dysregulated metabolic pathways contribute to immune cell dysfunction and autoantibody production.
• Targeting immunometabolism presents a promising therapeutic strategy for SLE.
