Review on Car-T Cell Therapy for Cancer Treatment

Abstract

A set of illnesses known as cancer involve abnormal cell proliferation and have the ability to invade or spread to different bodily regions. These stand in contrast to benign tumours, which remain stationary. A lump, unusual bleeding, a persistent cough, unexplained weight loss, and a change in bowel habits are all potential warning signs and symptoms. Chimeric antigen receptors (CARs), often referred to as chimeric immunoreceptors or artificial T cell receptors, are receptor proteins that have been modified so that T cells now have the ability to target a particular antigen. Because they integrate antigen-binding and T cell activation functions into a single receptor, the receptors are chimeric. CAR T cell treatment is a form of treatment in which the patient's immune cells, called T cells, are altered in a lab so that they will adhere to and kill cancer cells. An apheresis machine receives blood from a vein in the patient's arm through a tube, filters out all white blood cells—including T cells—and returns the remaining blood back to the patient. The T cells are then genetically modified in the lab to contain the gene for a unique receptor known as a chimeric antigen receptor (CAR). The CAR T cells are multiplied in a lab before being infused into the patient in large numbers. In order to destroy cancer cells, the CAR T cells can connect to an antigen on the cancer cells.
