| Abstract: | Chimeric antigen receptor (CAR) T cell therapy is a revolutionary approach in cellular immunotherapy, where a patient's T cells are genetically engineered to recognize and attack cancer cells. In the last decade, several CAR-T cell therapies have been approved by the FDA. However, this encouraging outcome was obtained only with certain blood cancers. Many research / clinical trials are now underway worldwide to extend the CAR T-cell therapy benefits to a large spectrum of cancers, using rodents. This model presents several drawbacks, such as the immunodeficiency of humanized models, ethical constraints, time, and cost. An alternative, pertinent, 3Rs-compliant in vivo model for developing CAR-T therapy is urgently needed. Xenografts on the chicken embryo's ChorioAllantoic Membrane (CAM) have proven extremely valuable for in vivo cancerology studies. In this work, we evaluated in vivo the anti-tumor efficacy of CD19-targeting CAR-T cells on human lymphoma using Inovotion's CAM assay. |
