Opening of scientists biologists make rewrite the textbooks on human anatomy

Antoine Louveau, a professor in the laboratory of the University of Virginia Health System ( UAV ), made a surprising discovery in the anatomy of the brain when studying твёрдую mater , - a membrane structure covering the brain - in mice. He invented a method of opening, allowing to keep untouched the membrane structure. Following the success of this procedure, the professor noticed covering its vessels which have appeared on the scrutiny of science for a long time are looking for the vessels of the lymphatic system.
Despite the fact that the scientists involved in human anatomy than a thousand years old, the body still remains a mystery, is not open to this day. For example, until recently, scientists did not know how the brain communicates with the lymphatic system of the body as the brain's immune system works and how it derived from waste products.
Лимфатическая System - part of the circulatory system in vertebrates, complementary cardiovascular. It plays an important role in metabolism and purifying cells and body tissues, and the immune system. With its help wastes internal organs displayed back to the blood.
Until recently, researchers were unable to detect in the cortex of the lymph vessels. It was believed that his biological waste discharged through the синусы Dura . It was not clear in this case should work his immune system. Even modern techniques like MRI did not give an answer to this question.
Kevin Lee, Doctor of Biological Sciences, and Chairman of the Department of Neurology University of UAV, describes his reaction to this finding as follows: "For the first time these guys have shown me result of their work , I said only one thing: 'We'll have to change all the textbooks." In the central nervous system has never been known to the lymphatic system. And according to the results of the work, which we then confirmed many times, it became clear that they radically change the perception of people about how the central nervous system works with the immune system ».
Head of the laboratory in which Louveau made this discovery, Jonathan Kipnis, was initially skeptical: "I could not believe that can be found in the body structure, previously unknown. I thought that everything has long been marked out, and that the opening of this account ended in the middle of the last century. Obviously, it is not ».
The unexpected discovery raises more questions than answers. For example, in Alzheimer's disease brain accumulates large "chunks" of proteins. Kipnis explains that this may be due to the fact that they simply are not removed from the brain at proper efficiency through the lymphatics.
We already know that with age, lymph vessels begin to look very different, and their further close study may shed light on the cause of brain diseases and ways of their treatment - from Alzheimer's disease and multiple sclerosis to autism.
