In biology, chimeric antigen receptors (CARs)—also known as chimeric immunoreceptors, chimeric T cell receptors or artificial T cell receptors—are receptor proteins that have been engineered to give T cells the new ability to target a specific antigen. The receptors are chimeric in that they combine both … See more The first chimeric receptors containing portions of an antibody and the T cell receptor was described in 1987 by Yoshihisa Kuwana et al. at the Institute for Comprehensive Medical Science in Aichi, Japan, and … See more The first step in the production of CAR T-cells is the isolation of T cells from human blood. CAR T-cells may be manufactured either from the patient's own blood, known as an autologous treatment, or from the blood of a healthy donor, known as an allogeneic treatment. … See more There are serious side effects that result from CAR T-cells being introduced into the body, including cytokine release syndrome and neurological toxicity. Because it is a relatively new treatment, there is little data about the long-term effects of CAR T-cell therapy. There are … See more The cost of CAR T cell therapies has been criticized, with the initial costs of tisagenlecleucel (Kymriah) and axicabtagene … See more As of March 2024, there were around 364 ongoing clinical trials happening globally involving CAR T cells. The majority of those trials target blood cancers: CAR T therapies account for more than half of all trials for hematological malignancies. CD19 continues to … See more Chimeric antigen receptors combine many facets of normal T cell activation into a single protein. They link an extracellular antigen recognition domain to an intracellular … See more Antigen recognition Although the initial clinical remission rates after CAR T cell therapy in all patients are as high as 90%, long-term survival rates are much lower. The cause is typically the emergence of leukemia cells that do not express CD19 and … See more WebSep 24, 2015 · Wu et al. designed T cells expressing chimeric antigen receptors that recognize and attack cancer cells with an additional control system. This mechanism would allow a doctor administering the therapy to turn the engineered T cell “on” or “off” by administering a small molecule that is required along with cancer cell antigen to ...
