CNS compartmentalization
The segregation of immune responses within different anatomical regions of the central nervous system.
Full Definition
CNS compartmentalization refers to the phenomenon where immune responses, inflammatory processes, and pathological changes occur in distinct anatomical compartments within the central nervous system, often with limited cross-communication. This includes separation between parenchymal, perivascular, meningeal, and cerebrospinal fluid compartments. Each compartment may harbor different immune cell populations, cytokine profiles, and pathological processes. Understanding CNS compartmentalization is crucial for interpreting biomarker data, as inflammatory markers in CSF may not reflect parenchymal inflammation, and vice versa. This concept has important implications for drug delivery and treatment strategies.
