Transcriptome analysis of T cells from Ldlr mice and effects of in vitro vitamin D treatment.

Vitamin D is known for its immunosuppressive effects on T cells, suppressing Th1 and Th17 and promoting Treg differentiation. Th1 cells contribute to inflammatory responses such as inflammatory cytokine production and macrophage activation, which accelerate the progression of atherosclerosis. However, the mechanisms underlying the modulation of T cell functions by vitamin D in atherosclerosis have not been investigated.

The effects of 1,25(OH)D treatment on metabolic reprogramming and maturation in bone marrow-derived dendritic cells from control and diabetic mice.

Activated dendritic cells (DCs) undergo significant metabolic reprogramming, which is characterized by an increase in aerobic glycolysis and a concurrent progressive loss of oxidative phosphorylation. The modulation of metabolic reprogramming is believed to be closely related to the function of DCs. Vitamin D has been reported to inhibit the maturation of DCs.
