General Information | Comment | Organism |
---|---|---|
physiological function | indoleamine 2,3-dioxygenase, by degrading L-tryptophan, enhances carnitine palmitoyltransferase I activity and fatty acid oxidation, and exerts fatty acid-dependent effects in human alloreactive CD4+ T-cells. The enzyme has an immunoregulatory role in various models of autoimmunity and allotransplantation. IDO increases fatty acid oxidation in mixed lymphocyte reactions and CPT1 enzymatic activity in mixed lymphocyte reaction-derived CD4+ T-cells. IDO decreases ACC2 expression, whereas it increases the level of phosphorylated ACC2 in mixed lymphocyte reaction-derived CD4+ T-cells. IDO increases L-tryptophan degradation in mixed lymphocyte reactions enhances eIF2alpha phosphorylation and CYP1A1 expression in mixed lymphocyte reaction-derived CD4+ T-cells, but does not affect p70S6K phosphorylation in mixed lymphocyte reaction-derived CD4+ T-cells | Homo sapiens |
