Improving the efficacy of cancer immunotherapy with modified CAR-T cells

CAR-T cell therapy is a last hope for many patients with blood, bone marrow or lymph gland cancer when other treatments such as chemotherapy are unsuccessful. A limiting factor of this otherwise very effective and safe therapy is that the cells used in the process quickly reach a state of exhaustion. CAR-T cells are one of the personalized cancer therapies and have been used in specialized centers in Europe since 2018. In this complex treatment, immune cells, or more precisely T cells, are taken from the blood of cancer patients, genetically engineered in the laboratory with a chimeric antigen receptor (CAR) and then re-administered.
