New Technique Strengthens Immune Cells to Fight Cancer



Konstantine Adamopoulos

New Stanford University Research has recently begun to show, enhance, and grow T-cells in living mice and in human cell cultures. These breakthroughs may be the key to pote
ntially surpassing the drawbacks of current immune cell therapy, which has not proven to be the most effective mechanism for the human body.


The way this new mechanism works is by means of a relatively new branch of biology, synthetic biology, "in which researchers can build new functions into cells by integrating pre-designed genetic components," or simply, in which researchers can alter cells with existing genetic makeups of other molecules.

Where the bar is raised between the old method of immune cell care and this new method, is to a height at which the adoptive immunotherapy targets the events that occur when the immune system cannot detect a pathogen or disease. This system works by harvesting T-cells from a patient, modifying the cells, then injecting them back into the place in the body where the disease is most prevalent.
In the past, this has been quite ineffective, due to the fact that the T-cells have not been able to destroy the pathogen on its own without help from other molecules. The new approach, is to further engineer the T-cells so that they can be self-dependent. In other words, 'fix' them and make them strong enough to battle pathogens and bacteria on their own.
