The bacteria travel through the body on stem cells


Scientists have discovered that leprosy pathogens - bacteria Mycobacterium leprae - to travel through the body using stem cells, which they themselves had created from glial (Schwann) cells.

Schwann cells surround the neurons in the brain, providing them with electrical insulation. This increases the speed of agitation. Glial cells in the brain are not inclined to seek adventure in the vast body and always prefer to stay in one place while their peaceful existence does not violate the leprosy bacteria.

Imbued in Schwann cells mycobacteria M. Leprae reprogram them, turning into stem cells and then use the past as a transport to move around in the body. Stem cells migrate over long distances, bringing the bacteria that cause leprosy to the muscles.

As the scientists explain, bacteria reprogram glial cells by switching off their "mature" genes and the inclusion of "child." Similarly, the stem cells are obtained Shinya Yamanaka, who was for it in 2012 was awarded the Nobel Prize.

The study authors noted that this phenomenon is very unusual for bacterial infections. Usually interfere in the management of the genes are not bacteria, and viruses. For example, before the virus was detected, zombie caterpillars shekopryada and causing them to climb trees to increase the territory of the spread of virions.
