Immunohistochemical staining for intercellular adhesion molecule-1 (ICAM-1) in the hippocampus. (A) Control; (B–D) hippocampal sclerosis (HS). In the control sections (A), vessels are weakly stained for ICAM-1. In contrast, in sections from patients with HS (B, C), ICAM-1 staining is diffusely increased in the fourth sector of the cornus ammonium (CA4), but not in the dentate gyrus (DG). (D) The preincubation of the ICAM-1 antibody with 5 µg/ml of ICAM-1 protein abolish the staining. Bars=200 µm (A, B, D) and 50 µm (C).
