Marrying immunotherapy with chemotherapy: why say IDO?
نویسندگان
چکیده
Activation of the tryptophan catabolizing enzyme indoleamine 2,3-dioxygenase (IDO) in cancer cells facilitates immune escape. A recent study now shows how small-molecule inhibitors of IDO can be used to leverage the efficacy of traditional chemotherapeutic drugs that are used to treat cancer in the clinic. By promoting antitumor immune responses in combination with cytotoxic chemotherapy, IDO inhibitors may offer a drug-based strategy to more effectively attack systemic cancer.

Blocking IDO activity to enhance anti-tumor immunity.
Tumors express potentially immunogenic antigens, yet the immune response to these antigens is typically profoundly suppressed. Patients with established tumors behave as if they were functionally tolerant to any antigens associated with the tumor. This tolerance reflects a process of active immune suppression elicited by the tumor, and represents a critical barrier to successful anti-tumor immu...
متن کاملNanomedicine and cancer immunotherapy: focus on indoleamine 2,3-dioxygenase inhibitors
Nanomedicine application in cancer immunotherapy is currently one of the most challenging areas in cancer therapeutic intervention. Innovative solutions have been provided by nanotechnology to deliver cytotoxic agents to the cancer cells partially affecting the healthy cells of the body during the process. Nanoparticle-based drug delivery is an emerging approach to stimulate the immune response...

Background & Objectives: Defect in Immune responses, such as immunosuppression is one of the major causes of AML pathogenesis and progression which could be targeted for immunotherapy of these patients. CD200 and IDO are immunoregulatory factors which are overexpressed in some solid tumors and hematological malignancies. Distinct researches have shown that CD200 and IDO expressions are associat...
متن کاملCombinatorial antitumor effects of indoleamine 2,3-dioxygenase inhibitor NLG919 and paclitaxel in a murine B16-F10 melanoma model
Indoleamine 2,3-dioxygenase (IDO) is involved in tumor immune escape and resistance to chemotherapy, and is clinically correlated with tumor progression. IDO inhibitors show marginal efficacy as single agents; therefore, combinations of these inhibitors with other therapies hold promise for cancer therapy. The aim of this study was to investigate the synergistic antitumor effects of IDO inhibit...
متن کاملThe indoleamine 2,3-dioxygenase pathway controls complement-dependent enhancement of chemo-radiation therapy against murine glioblastoma
BACKGROUND Indoleamine 2,3-dioxygenase (IDO) is an enzyme with immune-suppressive properties that is commonly exploited by tumors to evade immune destruction. Anti-tumor T cell responses can be initiated in solid tumors, but are immediately suppressed by compensatory upregulation of immunological checkpoints, including IDO. In addition to these known effects on the adaptive immune system, we pr...
