Viruses to Battle Late-Stage Cancer?

American scientists have made another breakthrough in the development of methods for combating late-stage cancer with the help of immunotherapy methods.

The new method of oncolytic viral therapy is to deliver a kind of molecular “bombs” to the metastases cells that develop at the late stages of the disease. Previously, such delivery was blocked by the patient’s immune system.

The development is underway at Emory University and Case Western Reserve University in the United States. During the experiment, scientists have modernized adenoviruses, making them “invisible” to the body’s immune system.

Such oncolytic viruses that can kill metastatic cancer cells are usually blocked by the immune system. However, using a modified virus, doctors hope to increase the effectiveness of the fight against cancer in the later stages of the disease.
