immunoprivilege
Unique immunological status of the CNS that limits inflammatory responses to protect neural tissue.
Full Definition
Immunoprivilege refers to the specialized immunological environment of the central nervous system that evolved to protect delicate neural tissue from potentially damaging immune responses. This phenomenon involves multiple mechanisms including the blood-brain barrier, limited antigen presentation, immunosuppressive factors, and restricted lymphatic drainage. However, immunoprivilege is not absolute, and under pathological conditions, the CNS can mount robust immune responses. Understanding immunoprivilege is crucial for comprehending how neuroinflammatory diseases develop and how therapeutic interventions might be designed to modulate CNS immunity.
