An infection with Bacillus anthracis (Anthrax) can lead to death, but surprisingly some people are virtually immune to it. Anthrax has been used as a biological weapon, but the health risk is not equal for all people. Researchers in the U.S. now know why this happens.
The phenomenon has genetic causes, is what tells the team of researchers at Stanford University in the journal PNAS (online publication - Bacillus anthracis comparative genome analysis in support of the Amerithrax investigation).
The researchers conducted tests on 234 volunteers of different ethnicities. Lymphocytes from three tested people began to react only when large quantities of the poison was placed in contact with the blood samples. These were referred to as immune. According to the researchers, the difference between the remaining cells were also too high. In the experiment, the cells of some specimens died when toxic concentration reached about 250 times the amount presented to cells of other people tested.
In other experiments with rats it was shown how the cells are sensitive to anthrax. genes It has been known that this sensitivity is determined by the activity of a gene. This gene directs the formation of a protein that is on the surface of the cell and regulates the entry of the poison inside the cells.
Until now it was unclear if the difference in sensitivity was stronger because of environmental factors genes or whether it was influenced by genetic factors. Is difficult to know which sensitive people and what people resistant to anthrax. When in doubt, it is preferable to maximum care for anthrax contamination.
