Tisagenlecleucel
Tisagenlecleucel, sold under the brand name Kymriah, is a CAR T cells medication for the treatment of B-cell acute lymphoblastic leukemia (ALL) which uses the body's own T cells to fight cancer (adoptive cell transfer). Serious side effects occur in most patients. The most common serious side effects are cytokine release syndrome (a potentially life-threatening condition that can cause fever, vomiting, shortness of breath, pain and low blood pressure) and decreases in platelets (components that help the blood to clot), hemoglobin (the protein found in red blood cells that carries oxygen around the body) or white blood cells including neutrophils and lymphocytes. Serious infections occur in around three in ten diffuse large B-cell lymphoma (DLBCL) patients. T cells from a person with cancer are removed, genetically engineered to make a specific chimeric cell surface receptor with components from both a T-cell receptor and an antibody specific to a protein on the cancer cell, and t ...

CAR-T
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 antigen-binding and T cell activating functions into a single receptor. CAR T cell therapy uses T cells engineered with CARs to treat cancer. The premise of CAR T immunotherapy is to modify T cells to recognize cancer cells in order to more effectively target and destroy them. Scientists harvest T cells from people, genetically alter them, then infuse the resulting CAR T cells into patients to attack their tumors. CAR T cells can be derived either from T cells in a patient's own blood (autologously) or from the T cells of another, healthy, donor ( allogeneically). Once isolated from a person, these T cells are genetically engineered to express a specific CAR, which programs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
