What is immunotherapy?
Immunotherapy is a revolutionary approach to cancer treatment that helps the immune system recognize and attack cancer cells1. Current immunotherapies include immune checkpoint inhibitors, CAR-T cells, vaccines, and monoclonal antibodies that, for a subset of patients, has provided long-term, durable responses to a variety of cancers. However, some patients fail to respond to treatment at all, while others achieve a limited response followed by tumor progression. Therefore, understanding the factors that contribute to an effective response and determining mechanisms of resistance will be critical as immunotherapies are applied more broadly2.
The role of the immune system
The function of the immune system is to protect against disease and clear the body of unhealthy, ailing cells, including cancer cells. T cells selectively recognize and kill pathogens and unhealthy cells by orchestrating a coordinated immune response, including innate and adaptive responses. However, various cancers have unique triggers that result in evasion from the immune response, making them more resistant to immunity3.
Immunotherapy involves strengthening the cancer patient’s immune system by improving its tumor recognition ability or providing a missing immune effector function to provide durable, adaptable cancer control4,5.

Key targets involved in tumor resistance: STING, IDO1, and VISTA
Stimulator of interferon genes (STING) is a signaling molecule that plays a crucial role in controlling the transcription of many host defense genes such as pro-inflammatory cytokines and chemokines. Previous studies into the roles of STING in immunomodulation showed the potential of STING agonists as cancer therapeutics to activate antitumor immune responses6.

Indoleamine 2, 3-dioxygenases (IDO1 and IDO2) are tryptophan catabolic enzymes that catalyze the conversion of tryptophan into kynurenine. The resulting depletion of tryptophan and subsequent increase in kynurenine exert important immunosuppressive functions, thus making IDO1 a potential therapeutic opportunity in cancer immunotherapy7.
|Recombinant IDO1 (anti-Indoleamine 2, 3-dioxygenase) antibody [EPR20374] (ab211017)Rabbit monoclonal to Indoleamine 2, 3-dioxygenaseSuitable for: WB, ICC/IF, Flow Cyt, IP, IHC-PReacts with: Human|
V-domain Ig suppressor of T cell activation (VISTA) is a novel checkpoint inhibitor that is a promising target for immunotherapeutic intervention due to its role in regulating innate and adaptive immune responses8.

Flow cytometry antibodies to support the studies of live cells
Flow cytometry allows the simultaneous, multi-parameter analysis of single cells and is a widely used method for characterizing and defining different cell types in a heterogeneous cell population. In recent years, the application of flow cytometry for analyzing the presence of cell types associated with a metastatic event, such as circulating tumor cells, has become more promising9.
Our range of recombinant, monoclonal antibodies are validated in flow cytometry and provide the highest level of consistency between batches, giving you the highly reproducible results your research requires.
