Astrocytic response to LPS application. Coronal sections of GFAP-immunostained motor cortex below the area of LPS application (Fig. 4b) or sham operation (Fig. 4a) on the contralateral (contra), control side, 3 days after application of LPS. Note that astrocytes are present throughout the full depth of cortex and are more brightly fluorescent in the LPS-treated cortex, with thicker processes than in the control cortex. Scale bar in Fig. 4a = 200 μm and also applies to Fig. 4b.
