The main scientists of skip to content have found mysterious channels, and the scientists connecting brain and skull have found mysterious channels, connecting brain and skull.

Russian news agency. Harvard biologists have found an unusual way to connect the bone marrow to the thickness of the skull and brain tissue, which can be explained, As immune cells enter his inflammation. Their conclusions are in the nature new century.

We plan to study the effects of these pathways on the development of Alzheimer's disease, stroke, hypertension and other inflammatory related diseases. In addition, they can also be used to deliver drugs directly to the brain. ") From the rest of the organism, the so-called brain blood cell barrier)（ All the blood vessels around the brain don't let anything enter it except oxygen and nutrients.

Scientists explained that the barrier is not a whole wall, but a "brick" composed of unique cells, with small channels between them, called "close contact". Recently, biologists have found that these contacts can expand under certain conditions, which can help the brain clean up waste. "

Narendorf and his colleagues inadvertently opened another possible back door, "infiltration of infected or immune cells into the human brain, research, How the immune system of mice responds to various forms of stroke caused by surgery or chemistry.

Surprisingly, narendorf, the first to be damaged by a rat's brain blood vessels, is not immune cells that form the tibia, the main factory "similar cells, but their." "Cousin formed in the skull."

"We look at the bones of the skull from all possible angles, trying to figure out how neutrality can penetrate the brain. "All of a sudden, we found a lot of micro channels that directly connect the bone marrow to the brain," narendorf continued

Further observation of these pathways suggests that cells can only move through these pathways if there is an infection in the brain or if cerebrovascular damage occurs during a stroke. In other cases, neutrophils infiltrate into bone containers, not the brain, and spread to all other parts of the body.

This structure is about five times the size of a human head. As scientists have suggested, they can pass not only through neutrophils, but also through other types of cells that have yet to be discovered and studied.

Their observations, Harvard biologists hope, will help us understand, How to produce different kinds of inflammation in the brain, and how to relate to neurogenesis and autoimmune diseases.
