Promising cancer therapy: tumors attack themselves

Scientists continue to work tirelessly to find the best cancer treatment. Learn about the findings of the latest technique created by the work team of the University of Zurich!

Cancer is one of the most aggressive diseases that kills people worldwide. Because of that, Over the years the scientific community has worked tirelessly to find effective treatments.

A group of scientists from the University of Zurich gathered together knowledge and created an innovative therapyto. The novel factor of this new treatment is that cancerous tumors manage to eliminate each other.

What the team of specialists did was modify the adenovirus, a group of infectious viruses that attacks the respiratory tract. That way, Through the alteration, they managed to generate antibodies that focus on directly attacking the tumor.

The modified genes that enter the body manage to guide the cytokines and each of the attacking agents towards the condition. Following this, the same cancer cells begin to generate antibodies that fight the tumor.

Because of this, the scientists affirmed that with this treatment it is possible to deceive the tumor. So much so that attacking agents are gradually produced that are responsible for eliminating the entire disease.

One of the most striking factors in this treatment is that the modified virus enters the body without the immune system activating any alarm. That way, the antibodies only enter the affected area and do not contaminate any of the cells that are in good condition.



The modified genes act in a controlled way, since by not being detected by the white blood cells, it is achieved that they are not distributed through the bloodstream. Because of this, healthy tissues are never at risk.

The advantage of this cancer treatment

The technique promoted by scientists at the University of Zurich has fewer side effects than alternatives such as chemotherapy. Then, in this case not all cells are attacked, but rather all antibodies are focused on the malignant tumor.

In this way, the patient’s body feels less attacked. This because of cells that are in good condition are left still, do not suffer any alteration or are eliminated along with the affected areas.

Tests

The scientists tested the treatment in a group of mice suffering from breast cancer. At that moment They discovered that as the days went by, a large number of antibodies began to be created around the affected area.

The working group used 3D visualizations to be able to analyze the effects that the modified gene had within the tumor. A) Yes determined that it was evident that the tumor was beginning to have porosities that were causing it to disintegrate.



To consider

With this test, scientists from the University of Zurich defined that this technique is a great option for treating breast cancer in people. Nevertheless, they also stated that with the inclusion of additional biologics it may be viable to treat all types of tumor conditions.

Following that fact, Scientists have the goal of continuing to refine the technique and provide evidence that will lead to much more effective and hopeful findings.
