Reductions in viral Ag in MAb recipients. N⁺, neutralizing; F⁺, fusion inhibiting. Inflammation within the spinal cords of infected μMT recipients of PBS (A), N⁻/F⁺ (B), or N⁺/F⁺ MAb (C) at day 21 p.i. (hematoxylin and eosin). Note comparable distribution of infiltration in the spinal cords of all groups of mice. Viral Ag in spinal cords of infected μMT recipients of either PBS (D), N⁻/F⁺ (E), or N⁺/F⁺ MAb (F) at 21 days p.i. (immunoperoxidase with hematoxylin counterstain). Bar = 1,200 μm. Arrows indicate infected oligodendrocytes. Arrowheads indicate infected astrocytes.
