2024Yuzaki at the Imperial Hotel on March 3, 2017.Purple Ribbon Medal Celebrationwas held。Despite the sunny Sunday、Approximately 100 people gathered from all over the country.。Thank you very much again。(Tokyo Marathon was being held on the road in front of the hotel.)。）

It was canceled for a while due to the coronavirus pandemic.Physiology class reunion was held。In the first half, there was a lecture by Professor Ayako Ishida, who studied abroad at the Yuzaki Lab and now works independently as a team leader at RIKEN CBS.、In the second half, we moved to the restaurant park to exchange opinions.、And it ended with the regular chorus of young blood.。

in the central nervous system、Astrocytes clear glutamate from the synaptic cleft.、Achieves proper synaptic function。However、How does the astrocytic glutamate transporter GLAST function around synapses?、it was still unclear。In this paper、Cell adhesion molecule (DSCAM) expressed in Purkinje cells、By controlling the localization of GLAST expressed in Bergmann glia、Climbing fibers were shown to be involved in Purkinje cell synapse formation and cerebellar motor learning.。This is a huge amount of work done by Mr. Dewa of Hoshino Lab.。For the Yuzaki lab, Kakegawa was in charge of electrophysiological analysis and eye movement learning test.。Nat Commun. 15:458, 2024.

How to covalently chemically label proteins without genetic manipulation、A powerful method for analyzing receptors。However、Selective target receptor labeling in the brain has not yet been established。there、In this research led by Mr. Nonaka of Kyoto University's Hamachi Laboratory,、using ligand-directed chemical reactions、We show that synthetic probes can selectively bind to target endogenous receptors in the brain of living mice。Kakegawa of Yuzaki Lab、As part of the joint research between CREST and ERATO, Arai、In this study, we showed that chemical labeling does not change receptor function.。Proc Natl Acad Sci USA. 121:e2313887121, 2024

GABA acts as a ligand for GluD1、A paper by Pierre Paoletti, Radu Aricescu et al. that reported that it promotes long-term potentiation of inhibitory synapses.（Science 2023)Mr. Ito wrote an explanatory article, Research Highlight, about (Ito and Yuzaki, Cell Research)。

Sponsored by Dept Biomedicine at the University of Bergen, NorwayAt BBB Seminar、Yuzaki gives a lectureThe we。It's a polar night and there's almost no daylight.、It was a rare heavy snow day even in Bergen, but we enjoyed a lively discussion.。

The 161st Brain Club welcomed Dr. Takero Saneyoshi (Kyoto University)。The title of the presentation was ``Cofilin inside the dendritic spine exhibits molecular activity through liquid-liquid phase separation."forming a sexual gradient"。Long-term potentiation (LTP) is considered a fundamental process of memory learning.) paper、Structural changes occur in which dendritic spines become larger over time, but the mechanism was not fully understood.。Dr. Saneyoshi found that the temporarily increased Ca concentration within the spine、Continuously activates calmodulin kinase (CaMKII) and its downstream enzymes.、As a result, the mechanism that changes the actin skeleton has been successfully clarified.。We all listened with great interest.。

Yuzaki will enjoy the honor of receiving the Medal with Purple Ribbon in the fall of 2023.。The Purple Ribbon Medal、Inventions and discoveries in the fields of science and technology、This is a badge of honor given by the country to people who have made outstanding achievements in academics, sports, and the arts.。The transmission ceremony and audience were held on November 13th.。The photo shows Machi Tawara representing the recipients at the ceremony.。This award was given in recognition of my achievements in the field of neuroscience.、of course、I would like to thank all the staff, postdocs, graduate students, technicians, secretaries, and many co-researchers who have worked with me thus far.。I am grateful for the congratulatory telegrams and emails I received from many people.。

10Held in Singapore on March 30th-31st、”A symposium on Neuroscience of Dementia“attended、Yuzaki gave a Keynote lecture。Another Keynote lecturer was Professor Hee-Sup Shin from South Korea.。This symposium is a group study similar to AMED in Japan.、It was the culmination of five and a half years of major grant research into dementia led by Professor George Augustine of Lee Kong Chian School of Medicine.。Additionally, on October 31st, Duke-NUS (National University of Sigapore)、We held a seminar。This was at the invitation of Mr. Nishiyama, who graduated from Yuzaki Lab and is independent at Duke=NUS (Photos here）。

26th-27th members of the Science Council of Japan(Part 2：Yuzaki was selected for Life Science)、10on the 2nd of the month、The appointment ceremony was held at the Prime Minister's Office.。6with a yearly term、Serve as vice chair of the 25th Basic Medical Science Committee。

The 5th UK-Japan Neuroscience Symposium was held in Wales, UK from August 31st to September 2nd.。Oral presentation by Mr. Shiozaki, a graduate student from Yuzaki Lab、Takasugi gave a poster presentation。Takasugi-kun was selected for the excellent poster award。Congrats!!It will be announced as an invitation to the next 6th Symposium as a prize.。In addition、Because Mr. Shiozaki was selected for the excellent poster award at the 4th UK-Japan Neuroscience Symposium、This time it was an oral invitation announcement.。This is a great achievement for the second consecutive year from Yuzaki Lab.。

The 160th Brain Club welcomed Dr. Teruyoshi Nakagawa (Vanderbilt University), who was temporarily returning to Japan.。The title is "Visualizing putative ions and water molecules in the ion conduction path of the AMPA receptor"。AMPA receptors are responsible for rapid excitatory transmission in the central nervous system、Elucidation of its structure and function is an important theme that expands the possibility of clinical application as well as basic science.。Dr. Nakagawa uses cryo-EM to、2.3Ca by resolution reaching Ų⁺The structure of transmissive AMPA receptor has been clarified。Interestingly, when a highly conserved gate (SYTANLAAF) in the AMPA receptor opens upon channel opening,、Ca in the same area²⁺you have told me to join。Probably Na⁺Along with inhibiting the influx of other ions such as、efficient Ca²⁺It is considered a mechanism for achieving transparency.、We all listened with great interest.。
