Application of Gene Therapy in Hemophilia.

Gene therapy refers to introducing normal exogenous genes into target cells to correct or compensate for the diseases caused by defective and abnormal genes for the purpose of therapy. It holds out hope of a cure for single-gene genetic diseases such as thalassemia, hemophilia, etc. At present, gene therapy is performed in two ways: introducing exogenous genes, and gene editing.

Decreased indoleamine 2,3-dioxygenase expression in dendritic cells and role of indoleamine 2,3-dioxygenase-expressing dendritic cells in immune thrombocytopenia.

Indoleamine 2,3-dioxygenase (IDO) expression in dendritic cells (DCs) can induce or maintain peripheral immune tolerance. Impaired IDO-mediated tryptophan catabolism has been observed in autoimmune diseases. In order to investigate the effects of IDO-mediated tryptophan catabolism and IDO-expressing DCs in immune thrombocytopenia, the concentrations of kynurenine were detected by high-pressure liquid chromatography.
