Develop a new "spray spray" 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 the spray on mice with advanced cancerous tumors and encapsulated the gel with calcium carbonate particles preloaded with anti-CD47 antibody, a protein released by cancer cells in order to prevent the destruction of the antibody and allow the immune system on the cancer cells and eventually destroy them. "

The researchers explained that the gel could activate T cells in the immune system to cause them to act together as another line of attack against cancer cells. Once the sprayed solution is sprayed at the surgical site, it forms quickly a gel with the nanoparticles, which dissolves gradually and releases the anti-CD47 antibodies. Body.
