Develop a new spray gel to help prevent the return of cancer after surgery

US researchers have developed an "aerosol gel", which has been tested on a number of mice. It has reduced the risk of recurrence of tumors in the body and controlled the development of tumors in other parts of the body.

The results showed that after treatment, 50% of the mice survived for at least 60 days without further tumor growth.

"This disposable gel is one of the biggest hurdles to cancer treatments," said Dr. Chen Ju, a professor at the University of California in the United States.

He added that about 90% of people with cancerous tumors eventually die as a result of a new tumor. It is therefore important to be able to develop something that helps reduce these risks.

In this study, the team tested most of the aerosols in mice with advanced skin cancer tumors and encapsulated the gel with calcium carbonate nanoparticles preloaded with anti-A (47), a protein released by cancer cells to prevent the destruction of the antibody and allow the cancer cell immune system and eventually destroy them. "

The researchers explained that the gel could activate T cells in the immune system to get them to work together as another line of attack against persistent cancer cells, and that once the solution sprayed on the site surgically, it rapidly formed a gel with nanoparticles that gradually dissolve and release antibodies against the protein A47 Body.
