According to the Researchers at National Cancer Institute, gene therapy proved to be successful for treatment of cancer due to the introduction of genes into human body.
The patients affected from skin cancer melanoma are treated with immune system cells (T-lymphotyces) to be taken from patient’s blood engineered to attack their tumours.
With the efforts of Surgeon Steven A Rosenberg, possible ways to manipulate human immune system were founded to fight cancer resulting in successful treatment on two patient suffering from skin cancer melanoma.
Surgeons take lymphocytes from the blood and inserted into them genes for a receptor having the ability of selecting a protein on melanoma cells called MART-1, allowing the lymphocyte to stick into a tumor cell and thereby killing it.
