A paper by Kaikan-kun has been published.。

Interview-kun's paper "C1ql1-Bai3 signaling is necessary for climbing fiber synapse formation in mature Purkinje cells in coordination with neuronal activity” was published in Molecular Brain magazine。Cerebellar Purkinje cells form multiple climbing fibers and synapses when young、Unnecessary synapses are pruned during development, except for one climbing fiber。In this paper、climbing fiber:1 Purkinje cell:1Even in the mature cerebellum, which has established the control mode of、By increasing the expression of C1ql1 and Bai3、Purkinje cells create multiple climbing fibers and synapses again、Climbing fibers usually branch in the anterior-posterior direction,、Newly formed synapses originate from branches of climbing fibers that diverge in the medial-lateral direction、They discovered that the presence of electrical activity in climbing fibers and Purkinje cells is necessary for new synapse formation.。Even when the GluD2 glutamate receptor is knocked out after maturation,、It is known that the internal and external branches of multiple climbing fibers form synapses with Purkinje cells.、We also found that this phenomenon is also dependent on C1ql1-Bai3 signaling。

The 155th BrainClub was held

In the 155th BrainClub、We invited Dr. Thomas Chater from the RIKEN CBS Synaptic Plasticity and Circuit Regulation Research Team (2/15(Wed) 16:00~17:30)。The subject was "Towards a logic of homo- and heterosynaptic dynamics following plasticity」です。from recent research、A phenomenon called "Heterosynaptic plasticity" has been found in which plasticity occurs in neighboring synapses when a plasticity-inducing stimulus is applied to a specific synapse.。For Chater teacher this time、Observation of spine morphology and Ca using hippocampal slice culture and two-photon microscopy2+learned from imaging、He gave a lecture on interactions between spines that cause heterosynaptic plasticity.。Regarding the spatio-temporal control mode between synapses、A heated discussion took place, including unpublished data.。Commemorative photo @ seminar room with members of Yuzuzaki Lab after the lecture (upper photo)。In the center is Mr. Chater, the performer.。It was a raging BrainClub rush。Hope next time。(Press conference)
