CAR T-cell therapy:
It is a treatment method where a patient's T cells, a type of immune system cell, are modified in a laboratory setting to target cancer cells.
T cells are extracted from the patient's blood, and in the lab, a gene for a specific receptor called a chimeric antigen receptor (CAR) is introduced into these T cells.
The CAR enables the modified T cells to bind to a particular protein found on the patient's cancer cells.
Following this modification, large quantities of CAR T cells are cultured in the laboratory and subsequently administered to the patient through infusion.
This therapy is primarily employed in treating certain types of blood cancers, and ongoing research is exploring its potential for treating other forms of cancer.
CAR T-cell therapy is also referred to as chimeric antigen receptor T-cell therapy.
