From: Minocycline attenuates interferon-α-induced impairments in rat fear extinction
Effect of interferon (IFN)-α treatment on fear extinction. Mean ± standard error of percent freezing compared to that of the vehicle. Rats (n = 8/group) were treated with 100, 200, or 400 IU IFN-α for the habituation, conditioning, and extinction trials. Vehicle or IFN-α was administrated after the rats experienced the habituation and conditioning trials. *p < 0.05 in the comparison (Tukey’s test) between vehicle and 400 IU IFN-α group. # p < 0.05 in the comparison between vehicle and 200 IU IFN-α group
