简介：
Overview
This study presents two optimized protocols for the rapid isolation of immune cells from the central nervous system (CNS), including the brain, spinal cord, and meninges. These methods facilitate the analysis of immune cell phenotype, function, and localization under both steady state and inflammatory conditions.
