Doctors have discovered that nanoparticles of iron help the body fight cancer

A group of specialists under the leadership of Heike Daldrup-link found an unusual and yet a very promising property of iron nanoparticles. As shown by experiments on mice, when injected into the body, these nanoparticles cause macrophages to attack the cancerous cells, thereby helping the body to fight against dangerous disease.

As the scientists explain, the results obtained to some extent, become for them a surprise. The fact that the original purpose of the trials was to test other previously discovered the useful properties of iron nanoparticles is that they help to restore the level of hemoglobin in the body after losing a large amount of blood, or in the case of anemia — a disease also called anemia in which the hemoglobin concentration is reduced.

Checking develop a cure for anemia to the presence of side effects, the researchers drew attention to the fact that it has an impact on the behavior of macrophages — cells that play a key role in the immune system and, in particular, to ensure the ability of the body to get rid of bacteria and unhealthy cells.

Scientists have suggested that iron nanoparticles can be used to fight cancer and to test this assumption, I conducted a series of experiments on mice. Doctors have introduced one rodents nanoparticles and one of the existing medicines, others — only particles, and the third did not make any injections. As it turned out, in the control group, the immune system did not respond to the growth of tumors, but in the first and second group of rodents, iron nanoparticles allowed the macrophages to attack the cancerous cells, thereby allowing the body to resist the worsening of the condition.

Scientific work, written on the results of the tests, the scientists published in the journal Nature Nanotechnology.
