Figure 1. Inflammation-Induced Impairment of Contextual Fear Memory Is Absent in Gabra5−/− Mice and Can Be Prevented by Pharmacological Inhibition of α5GABAA Receptor in WT Mice.
(A) IL-1β reduced the freezing scores for contextual fear memory only in WT mice. The bar graph shows the summarized results.
(B) L-655,708 or MRK-016 restored the freezing scores for contextual fear memory to control values in WT mice.
(C) LPS reduced the freezing scores for contextual fear memory only in WT mice, and L-655,708 restored the freezing scores to control values in WT mice.
(D) IL-1β did not affect the freezing scores for cued fear memory in response to tone in both WT and Gabra5−/− mice. Data are represented as mean ± SEM. Here and in subsequent figures, Con stands for control. *p < 0.05, **p < 0.01, ***p < 0.001, N.S.: nonsignificant result. See also Figure S1.
