Title: Potential of Chimeric Antigen Receptor T-Cells in Cancer Therapy
Abstract: Novel approaches for targeted delivery like nanoparticles, liposomes, polymer conjugates, etc. with better safety profile needs to be developed for cancer treatment. Chimeric antigen receptors (CAR) with modified thymus cells (T-cells) showed greater potential as a therapy due to its direct effect on immune system responsible for destruction of pathogens and said equivalent to the living drug. On activation of T-cell, it binds to the antigen domains treating refractory or relapsed cancers. The receptors are termed chimeric as it consists of T-cells functioning as well as antigen-binding combined in sole receptor. This therapy showed positive success towards hematological cancers and engineered for specific protein targeting. Though the therapy is associated to several challenges like incompetence towards tumor lysis and cytokine release rate, termination of cytotoxic activity after completion of tumor eradication, etc. The control mechanisms used by CAR T-cells are apoptosis by suicide genes, dual-antigen receptor, ON-switch tumor attack and bispecific molecules as activation switch. In solid tumors, CAR T-cell therapy showed promising signs of efficacy becoming a game-changing cell therapy. CAR T-cells are optimized using different engineering resolutions and lead to broadways for therapy adoption to benefit the cancer patients.
