[The features of the brain immune system in brain neoplasms]

Examining responses of the local immune system of the brain in neurocancer patients suggests that the immune system is involved in the neuroimmune interaction of both physiological and pathological conditions in the central nervous system (CNS). The setting off the local immune system of the brain is of functional nature, similar to functional analogy with the local system of the mucosae. By functional analogy, the aggregate of immune responses in the nervous tissue and cerebrospinal fluid should be called local and the system that includes these responses should named the local immune system of the brain. Due to the fact that nervous, endocrine, and immune regulatory pathways intersect in the CNS (hypothalamus), it is expedient to call this aggregate of defensive factors and mechanisms in CNS more broadly--the neuroimmune system.
