Cerebellum is thought to be involved in non-motor learning in motor learning and other。actually、Cbln1 and GluD2 but we know it is possible to control the selectively expressed in synapse formation in the cerebellum synapse、By these genetic mutations will occur human cognitive impairment。But these disorders was not clear about whether due to abnormality in the cerebellum。In this study、By examining fear conditioning training using mice lacking forebrain or cerebellum specifically Cbln1、Cbln1 each expressing before the brain and cerebellum、That you are responsible for specific functions in fear conditioning learning it was revealed for the first time。Otsuka is Mr. of the thesis of yuzu 﨑研。Hokkaido University Ken Watanabe of Konno teacher (co-first author)、It is the result of joint research with Abe teacher of Niigata Osaki village Research。

In small brain circuit、Presynaptic releases a complement family molecule Cbln1、It will combine to Nrx present in the presynaptic。On the other hand、Cbln1 will cause the synapse formed by combining at the same time also to the postsynaptic delta type 2 glutamate receptor (GluD2)。Nozawa-kun, together with Hayashi-san、Nrx-Cbln1-GluD2 the structure of the three-party complex that was the first time Tokiakasa。as a result、Cbln1 not only serve to anchor the presynaptic and postsynaptic as adhesive、To adjust the work of the GluD2 of postsynaptic、Synaptic plasticity (long-term depression (LTD)) It is possible to control the now clear。This study is a result of joint research with Aricescu Dr. Oxford University、It is a joint responsibility author paper。

Kainate receptors of the glutamate receptor、There was particularly high in specific synapses of the hippocampus, an important brain region in memory and learning、The transmission rate that is slow not to other receptors、And the essential role in the integration of hippocampal neural network activity。However、Whether incorporated only to certain synaptic kainate receptors what mechanism、The mechanism was not well understood。In this paper, the、By neurons secrete proteins called the C1ql2 and C1ql3、I found that coming to collect the kainate receptors directly。further、In the hippocampus of mice lacking the C1ql2 and C1ql3、Kainate receptors is not incorporated into the synapse、Be less likely to occur epileptic seizures was found be given a stimulus to induce epileptic artificially。C1ql2、C1ql3 is also present in various brain regions、Are considered each by controlling the built-in and function of kainate receptor synaptic neural make up the appropriate neural network activity。The results of this research、It is expected to be of use in the therapy method development and cause elucidation of epilepsy and autism。Keiko Matsuda is a lecturer and Tim Budisantoso Mr. of work。
