Methyl-supplemented nutrition delays the development of autoimmune disease in pristane-induced murine lupus

Immunology. 2024 Mar 2. doi: 10.1111/imm.13774. Online ahead of print.ABSTRACTThe aetiology and progression of systemic lupus erythematosus (SLE) resulted from a complex sequence of events generated both from genetic and epigenetic processes. In the current research, the effect of methyl-supplemented nutrition on the development of SLE was studied in the pristane-induced mouse model of the disease. The results clearly demonstrated decreased anti-dsDNA antibody and proteinuria levels, modulation of cytokines and protected renal structures in the group of treated mice. An additional increase in the DNA methylation of mouse B lymphocytes was also observed. The beneficial effect of the diet is due to the methyl-containing micronutrients with possible anti-inflammatory and immunomodulating effects on cell proliferation and gene expression. Since these components are responsible for maintaining the physiological methylation level of DNA, the results point to the central role of methylation processes in environmentally triggered lupus. As nutrition represents one of the major epigenetic factors, these micronutrients may be considered novel agents with significant therapeutic outcomes.PMID:38430118 | DOI:10.1111/imm.13774
