Experts from Duke University proved that the human immune system is involved in the development of dementia. The microglial cells surrounding the neurons, absorb the amino acid arginine, resulting in signs of memory impairment. The tool, developed by scientists must stop this pathological mechanism, says Zee News.
The immune system of mice is almost indistinguishable from a human. In the study, researchers noticed that microglial cells in the early stages of Alzheimer's disease began to divide and mutate. This occurred under the influence of the enzyme arginase that breaks down arginine. Developed the drug protected the animals from damage to the nervous system and prolonged life.
The discovery, scientists say, should help in the development of effective treatment of dementia and Alzheimer's disease.
