Immunohistochemical quantification.

IHC label	NBH + poly I:C	ME7 + saline	ME7 + poly I:C
IBA-1	48 ± 5	172 ± 15∗	172 ± 14∗
IL-1β	ND	ND	49 ± 29∗
TUNEL	1 ± 1	6 ± 1∗	12 ± 3∗

IL-1β and TUNEL counts were performed in the hippocampus and thalamus in 10 μm coronal sections, 3 and 15 h, respectively after poly I:C administration. IBA-1 counts were performed in a 0.62 × 0.47 mm region of the hippocampus. ND signifies that positive cells were not detectable. Significant differences to NBH + poly I:C controls by one-way ANOVA and Bonferroni post hoc tests are signified by ∗p < 0.05.
