Figure 2From: Brain leukocyte infiltration initiated by peripheral inflammation or experimental autoimmune encephalomyelitis occurs through pathways connected to the CSF-filled compartments of the forebrain and midbrain Immune cell localization in parenchymal and ventricular compartments in the brain of control rat. (A) Leukocytes are preferentially associated with the CPs (illustrated here in the fourth ventricle). A high magnification is shown in the insert. (B) Leukocytes in brain parenchyma are CD68+ cells associated with perivascular spaces. Blood vessels are visualized by laminin. (C) Occasional cells not associated with blood vessels are seen in a subependymal position. Scale bar, 50 μm. 3 V, third ventricle; ep, ependyma; Lm, laminin.Back to article page
