摘要 Objective To determine the spatio-temporal expression of p70S6k activation in hippocampus in mesial temporal lobe epilepsy. Methods Temporal lobe epilepsy model was established by stereotaxically unilateral and intrahip-pocampal injection of kainite acid (KA) in adult male C57BL/6 mice. Latent and chronic epileptogenesis were represented by mice 5 days after KA injection (n=5) and mice 5 weeks after KA injection (n=8), respectively. Control mice (n=5) were injected with saline. Immunohistochemical assays were performed on brain sections of the mice. Results Hippocampus both ipsilateral and contralateral to the KA injection displayed significantly up-regulated pS6 immunoreactivity in dispersed granule cells in 5-day and 5-week model mice. Conclusion The activation of p70S6k is mainly located in the dentate gyrus in KA-induced mouse model of temporal lobe epilepsy, indicating that the activation may be related with the disperse degree and hypertrophy of granule cells.
