The ability of the brain to change structurally and functionally with experience is called brain plasticity. High levels of pro-inflammatory cytokines impair normal memory formation and consolidation. To better understand the role of pro-inflammatory cytokines in learning, the contribution of the cytokine interleukin-6 (IL-6) to a motor skill learning task investigated. The Fmr1 Knockout (KO) mouse, an animal model of Fragile X Syndrome, has demonstrated impaired neural plasticity and learning. Fmr1 KO and control wild-type (WT) mice were trained on the dowel and flat beam runways to study motor skill learning and motor activity respectively. The cerebellum from the animals was examined for IL-6 protein using ELISA. No significant differences in the levels of IL-6 in the cerebellum of the Fmr1 KO and WT normal mice were found. The expression of IL-6 was not altered by the behavioural training. These results suggest lack of association between IL-6, and FMRP and motor skill learning.
