Figure 3.

Photomicrographs of IL-1β (a, b, c, d) and IL-6 (e, f) in hippocampus (dentate gyrus) from a control (a, b, e) and epileptic patient (no. 5) (c, d, f). Only a weak IL-1β staining was found in control patient (a, b, e) in contrast to the epileptic patient (c, d, f). The staining was mainly confined to the neurovascular unit. Figures show transverse sections at different magnifications (a, c, e: ×4; b, d and f: ×20). Scale bar: 100 μm. Isotype antibody controls are shown as inserts in a and c.
