Find resources and tools for understanding tumor-specific response and resistance to cancer immunotherapies.
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 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.

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.
Rabbit monoclonal to STING
Suitable for: WB, ICC/IF, IP, IHC-P, Flow Cyt
Reacts with: Human
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.
Rabbit monoclonal to Indoleamine 2, 3-dioxygenase
Suitable for: WB, ICC/IF, Flow Cyt, IP, IHC-P
Reacts 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.
