在大脑成熟过程中,星形胶质细胞形成了复杂的形态结构,展现出强烈的结构可塑性。连接蛋白30(Cx30),是一种在出生后表达的缝隙连接通道形成蛋白,在发育过程中通过控制细枝状突起的分支和延伸来动态调节星形胶质细胞的形态特性。然而,其背后的机制尚未被探索。我们在体外发现Cx30在星形胶质细胞中与肌动蛋白细胞骨架相互作用,并在细胞迁移期间抑制其结构重组和动态变化。

The Jiangmen Underground Neutrino Observatory(JUNO)is a large liquid scintillator detector designed to explore many topics in fundamental *** this study,the potential of searching for proton decay in the p→νK^(+)mode with JUNO is *** kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for ***,the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed *** on these advantages,the detection efficiency for the proton decay via p→νK^(+)is 36.9%±4.9%with a background level of 0.2±0.05(syst)±0.2(stat)events after 10 years of data *** estimated sensitivity based on 200 kton-years of exposure is 9.6×1033 years,which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies.
