Fig. 2: Cellular localization of TLR7 in the CA1 region from control and KA-injected (3 days postinjection) mice.

Double immunofluorescence staining showed that TLR7 was activated in KA, and most TLR7 colocalized with NeuN (a) and less colocalized with Iba-1 (b) but did not colocalize with GFAP (c). Arrowheads indicate TLR7-positive cells, NeuN-positive neurons, Iba-1-positive microglia, GFAP-positive astrocytes, TLR7-positive/NeuN-positive neurons, and TLR7-positive/Iba-1-positive microglia. Scale bar = 50 μm.
