A secret organ may exist in the human skull - scientists

Researchers have identified a previously unknown immune system structure in the skull cavity of mice, which may perform a protective function by helping to recognize and curb the development of brain tumors at early stages. Scientists suggest that a similar organ may exist in humans, opening new possibilities for the treatment and prevention of brain cancer.

Researchers have identified a previously unknown immune system structure in the skull cavity of mice. According to their hypothesis, this organ may perform a protective function, helping the body recognize and curb the development of brain tumors at early stages. So far, the unusual immune structure has only been found in mice, but researchers suggest that a similar organ may exist in the human body. In the future, influencing its function could open new possibilities for the treatment and prevention of brain cancer. Lead author of the study, Chang Hyun Park, emphasized: "We have never seen such structures in healthy bone marrow before. This is a fascinating discovery, indicating that the complex brain needs its own specialized immune structures for protection." For a long time, scientists believed that the immune defense of the brain and other organs operates almost independently. The central nervous system was considered an isolated zone where immune cells from other parts of the body should not penetrate, as this could lead to damage to nerve tissues and the development of neurodegenerative diseases.
