Researchers Find Missing Link Between the Brain and Immune System

We fixed the meninges within the skullcap, so that the tissue is secured in its physiological condition, and then we dissected it. After noticing vessel-like patterns in the distribution of immune cells on his slides, he tested for lymphatic vessels and there they were. The soft-spoken Louveau recalled the moment: Maps of the lymphatic system: University of Virginia Health System.

The unexpected presence of the lymphatic vessels raises a tremendous number of questions that now need answers, both about the workings of the brain and the diseases that plague it.

The findings have been published online by the prestigious journal Nature and will appear in a forthcoming print edition. The article was authored by Louveau, Smirnov, Timothy J.

David Peske, Noel C. Derecki, David Castle, James W. Mandell, Lee, Harris and Kipnis. Louveau was a fellow of Fondation pour la Recherche Medicale. Advanced search lets you search selected properties of the classification. You could search all properties or a selected subset only. First, you need to provide keywords in the Search Text field then check the properties that you'd like to include in the search.

The system will search for the keywords in the properties that you've checked and rank the results similar to a search engine. The results will be displayed in the Search Results pane. If the search query hits more than results, then only the top will be displayed. If you provide more than one keyword, the system will search for items that have all the keywords. It's possible to have the results that have either one or another keyword. The thymus is located in the chest just above the heart, according to Merck Manual.

This small organ stores immature lymphocytes specialized white blood cells and prepares them to become active T cells, which help destroy infected or cancerous cells. Tonsils are large clusters of lymphatic cells found in the pharynx. According to the American Academy of Otolaryngology , they are the body's "first line of defense as part of the immune system. They sample bacteria and viruses that enter the body through the mouth or nose. Lymph is a clear and colorless fluid; the word "lymph" comes from the Latin word lympha , which means "connected to water," according to the National Lymphadema Network.

Plasma leaves the body's cells once it has delivered its nutrients and removed debris. Most of this fluid returns to the venous circulation through tiny blood vessels called venules and continues as venous blood.

The remainder becomes lymph, according to the Mayo Clinic. Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction — upward toward the neck. Lymphatic vessels connect to two subclavian veins, which are located on either sides of the neck near the collarbones, and the fluid re-enters the circulatory system, according to the Mayo Clinic.

Diseases and disorders of the lymphatic system are typically treated by immunologists. Vascular surgeons, dermatologists, oncologists and physiatrists also get involved in treatment of various lymphatic ailments. There are also lymphedema therapists who specialize in the manual drainage of the lymphatic system. The most common diseases of the lymphatic system are enlargement of the lymph nodes also known as lymphadenopathy , swelling due to lymph node blockage also known as lymphedema and cancers involving the lymphatic system, according to Dr.

James Hamrick, chief of medical oncology and hematology at Kaiser Permanente in Atlanta. When bacteria are recognized in the lymph fluid, the lymph nodes make more infection-fighting white blood cells, which can cause swelling.

The swollen nodes can sometimes be felt in the neck, underarms and groin, according to the NLM. Lymphadenopathy is usually caused by infection, inflammation, or cancer. Infections that cause lymphadenopathy include bacterial infections such as strep throat, locally infected skin wounds, or viral infections such as mononucleosis or HIV infection, Hamrick stated. In some areas of the body the enlarged lymph nodes are palpable, while others are to deep to feel and can be seen on CT scan or MRI.

Inflammatory or autoimmune conditions occur when a person's immune system is active, and can result in enlargement of lymph nodes. This can happen in lupus, according to Hamrick. Lymphoma is cancer of the lymph nodes. It occurs when lymphocytes grow and multiply uncontrollably. There are a number of different types of lymphoma, according to Dr.

Sharman , director of research at Willamette Valley Cancer Institute and medical director of hematology research for the U. Non-Hodgkin lymphoma is more common of the two, according to the Lymphoma Research Foundation.
