Abstract：
:Though accumulating literature implicates that cytokines are involved in the pathophysiology of mental disorders, the role of interleukin-6 (IL-6) in learning and memory functions remains unresolved. The present study was undertaken to investigate the effect of IL-6 on amygdala-dependent fear learning. Adult Wistar rats were used along with the auditory fear conditioning test and pharmacological techniques. The data showed that infusions of IL-6, aimed at the amygdala, dose-dependently impaired the acquisition and extinction of conditioned fear. In addition, the results in the Western blot analysis confirmed that JAK/STAT was temporally activated-phosphorylated by the IL-6 treatment. Moreover, the rats were treated with JSI-124, a JAK/STAT3 inhibitor, prior to the IL-6 treatment showed a significant decrease in the IL-6 induced impairments of fear conditioning. Taken together, our results demonstrate that the learning behavior of rats in the auditory fear conditioning could be modulated by IL-6 via the amygdala. Furthermore, the JAK/STAT3 activation in the amygdala seemed to play a role in the IL-6 mediated behavioral alterations of rats in auditory fear learning.
