An injection of antibodies, considered revolutionary American scientists could contribute to the eradication of many types of cancer, according to a recent study by researchers at Stanford University in the United States, reports dailymail.co.uk.
The new type of antibody injection may eradicate several types of cancer in an advanced state, the destruction of the tumors. Researchers believe that the immune system can be trained in this way to attack several types of cancer - melanoma, pancreatic, breast and lung.
Scientists from the Faculty of Medicine at Stanford University believe that these antibodies created in the laboratory, could destroy not only incipient tumors but also metastatic which were spread throughout the body.
Professor Edgar Engleman, who led the study, said: "The potential is huge. We are seeing, in fact, the eradication of tumors."
Unlike other treatments, which relies on a different approach, targeting certain types of cancer, new treatment targets a much wider range of solid tumors.
Treatment is based on the same mechanism that causes the body to reject the transplanted organs, says American researchers.
In both cases, the antibodies - molecules that detect foreign substances in the body - activates the immune system.
They stick to the foreign tissue specific proteins - in this case, tumor - and, by the use of cell signaling role in T cells then act as either a "rapid response team" of the body.
When T cells are in contact with tissue "foreign" attacked him and destroy him.
Researchers have isolated antibodies in the body of mice proved resistant cancer.
Then, American scientists injected these antibodies along with certain chemicals to activate cells beacon role, dendritic cells in the body of mice with cancer.
These rodents have reactivated the immune system and then remained healthy, cancer-free for over a year.
Once they recognize cancerous tissues, T cells have multiplied and attacked not only tumors, but "hunted" and all metastatic cells circulating through the body.
American scientists say that both antibodies and signaling cells, dendritic cells play a crucial role in the elimination of tumors.
"Just a few hours after injection, the tumor cells were already covered by antibodies," they stated.
By adding a chemical substance that stimulates cell growth signaling role, dendritic cells, in the same injection with antibodies, researchers at Stanford University have been able to achieve the eradication of six different types of cancer - two types of melanoma, lymphoma, breast, lung and pancreatic.
Although the study was conducted on mice, scientists Americans say tests conducted on human cells in vitro showed similar results on the immune response.
The study was published in the journal Nature.
