Because of its safety, effectiveness, and low adverse reactions, it has become the fourth model of tumor treatment after surgery, radiotherapy and chemotherapy (Clin Cancer Res). , 1997; 3: 2623-2629), which achieves anti-tumor effects by mobilizing the host's natural defense mechanisms, such as inhibiting IDO-mediated tumor immune escape mechanisms, or by administering naturally occurring highly targeted substances.

  • T-cells In the cell cycle of T-cells, there is a regulation point that is very sensitive to tryptophan levels.
  • IDO depletes local tryptophan, causing T-cells to arrest in the middle of G1 phase, thereby inhibiting the proliferation of T cells;
  • IDO catalyzes the main product produced by the metabolism of tryptophan.
  • Canine urea is induced by oxygen free radicals to induce changes in intracellular oxidants and antioxidants to induce T-cell apoptosis, which is an intrinsic immunosuppressive mechanism present in the body.
  • IDO is highly expressed in leukemia cells, which inhibits the proliferation of local T cells, inhibits T-cell-mediated immune responses, and blocks T-cell activation signal transduction, thereby mediating tumor cell escape. The attack of the immune system. Most human tumors have been found to constitutively express IDO (J Exp Med. 2002; 196(4): 459-68, Nat Med. 2003; 9(10): 1269-74, Trends Mol Med. 2004; 10(1) ): 15-8).
