CAR-T cell engineering is a synthetic biology approach that modifies T-cells, a type of white blood cell, by inserting genetic material to enable them to recognize and destroy cancer cells.
It addresses the challenge of targeting and eliminating cancer cells without harming healthy tissue, offering an alternative to traditional chemotherapy that often has severe side effects.
T-cells are isolated from the patient's blood, genetically engineered in vitro to express chimeric antigen receptors (CARs) specific to a tumor-associated antigen, then multiplied and infused back into the patient. These CAR-T cells can identify and kill cancer cells expressing the target antigen.
The process involves isolating T-cells from a patient's blood sample, genetically modifying them in a laboratory setting using viral vectors or CRISPR technology, culturing the modified cells to expand their numbers, and then infusing them back into the patient.
Cells are first isolated, followed by transduction with a vector containing the CAR gene. Cells are then expanded ex vivo before reinfusion. This process requires precise control over cell culture conditions and stringent quality assurance measures.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and other lab processes.
