Brain and immune system connected by lymphatic vessels
Brain and immune system. Important discovery for those suffering from autism, Alzheimer’s and multiple sclerosis.
High hopes for those suffering from autism, Alzheimer’s but also multiple sclerosis: the brain is directly linked to the immune system via the lymphatic vessels that previously thought did not exist. These vessels may have escaped detection when the lymphatic system has been mapped throughout the body. This was stated by a study done on mice, the University of Virginia School of Medicine and published in Nature.
So far, the failure to observe the lymphatic vessels of the brain was probably due to the fact that they were “hidden very well,” explained Jonathan Kipnis, one of the authors of the research. Today, the images of these vessels, discovered thanks to an intuition of Antoine Louveau were `catturate’ in a complex area, the” breasts “, cavities in the bones of the face that are connected to the nasal cavity. Their presence raises questions about the brain and of certain diseases.
For example, in AD, as explained Kipnis
“There are accumulations of large blocks of proteins in the brain that we think can be accumulated because they were not efficiently removed by these vessels.” And there are other neurological conditions, from autism to multiple sclerosis, which must be reconsidered in the light of this discovery.
Kevin Lee, who chairs the Department of Neuroscience, concludes:
“The first time they showed me the basic result, I said: ‘They will have to change the textbooks.”
