Scientists develop intelligent protein molecules to successfully "eat" cancer cells in the body

The team designed an intelligent protein molecule that can recombine white blood cells that ignore the self-defense mechanism, thus preventing cancer cells from surviving and spreading in the body The researchers report that the research will lead to a new way to regenerate immune cells to fight cancer and infectious diseases The results, published in the journal Nature letters, were led by Professor Wang yingxiao, a bioengineering expert at the University of San Diego, California In the report, the team leader recorded the research process in detail and said that this method has been successfully tested in a living cell culture system The researchers named this intelligent protein "isnaps" (integrated sensing and activating protein) to detect precise molecular signals in response to living cells, act to make these signal cells resistant to disease, or perform other beneficial functions The study is the first to show that two sensing and activation functions can be combined into a single molecule, which is a leap forward in the use of intelligent biotechnology to fight diseases The researchers awarded isnaps a kind of leukocyte macrophage, and the results showed that they greatly enhanced the phagocytic ability of macrophages and could destroy the rapid division of cancer cells Macrophages are part of white blood cells, which play an important role in the immune system Their task is to remove foreign particles and other harmful biological pathogens, as well as to find tumor cells, and digest them When macrophages find tumor cells or other foreign invaders, macrophage surface protein will send out a "eat me" signal, suggesting that macrophages devour and destroy invaders.
