Conducted by the American experts, the study pointed to the ability of tobacco smoke to “Wake up” the dormant cancer cells and help them multiply in the body. In particular, the scientists were able to notice the influence of tobacco smoke on the activity of specific cell types neutrophils. The report on this work was published in the journal Science.
The researchers were exposed to tobacco smoke mice, and found: under its influence aktiviziruyutsya neutrophils – the cells that drive the immune system to actively respond, for example, when injected into the body of foreign germs. Immune response induced by neutrophils can in turn stimulate dormant cancer cells. Such cells are capable of years to accumulate in the body, yet do not receive stimulus for growth, and dramatically activate the immune system just has to be.
“Under the influence of tobacco smoke in mice cancer cells were not only awake, but also actively to share it. The main role in this process is played not so much agents, as the immune system’s response to them,” the researchers noted.
According to scientists, the activation of the immune response, on the one hand, to destroy cancer cells. But the paradoxical discovery was that the immune activity contributes to the revival and proliferation of the dormant or latent cancer cells. This resting cells, which have slowed metabolism, and are capable of withstanding the effects of radiation therapy and chemotherapy. It sleeping cancer cells make possible the recurrence of the tumor.
In addition to tobacco smoke, can cause unwanted immune activity can bacterial infection and chronic stress, added the scientists.
