The conventional perception of astrocytes as mere supportive cells within the brain has recently been called into question by empirical evidence, which has revealed their active involvement in regulating brain function and encoding behaviors associated with ***, astrocytes in the basolateral amygdala have been found to play a role in the modulation of anxiety-like behaviors triggered by chronic stress. Nevertheless, the precise molecular mechanisms by which basolateral amygdala astrocytes regulate chronic stress–induced anxiety-like behaviors remain to be fully elucidated. In this study, we found that in a mouse model of anxiety triggered by unpredictable chronic mild stress, the expression of excitatory amino acid transporter 2 was upregulated in the basolateral amygdala. Interestingly, our findings indicate that the targeted knockdown of excitatory amino acid transporter 2 specifically within the basolateral amygdala astrocytes was able to rescue the anxiety-like behavior in mice subjected to stress. Furthermore, we found that the overexpression of excitatory amino acid transporter 2 in the basolateral amygdala, whether achieved through intracranial administration of excitatory amino acid transporter 2agonists or through injection of excitatory amino acid transporter 2-overexpressing viruses with GfaABC1D promoters, evoked anxiety-like behavior in mice. Our single-nucleus RNA sequencing analysis further confirmed that chronic stress induced an upregulation of excitatory amino acid transporter 2 specifically in astrocytes in the basolateral amygdala. Moreover, through in vivo calcium signal recordings, we found that the frequency of calcium activity in the basolateral amygdala of mice subjected to chronic stress was higher compared with normal *** knocking down the expression of excitatory amino acid transporter 2 in the basolateral amygdala, the frequency of calcium activity was not significantly increased, and anxiety-like behavior was ob

采用二维快速液相色谱-串联飞行时间质谱(UPLC-QTOF)对卡铂注射液中的未知杂质结构及其与辅料的相关性开展研究。一维采用苯基-己基硅烷键合硅胶色谱柱(250 mm×4.6 mm,5μm),硫酸四丁基铵缓冲液(pH 7.5)-乙腈为流动相进行梯度洗脱,二维采用快速液相色谱-串联飞行时间质谱(UPLC-QTOF),HSS T3色谱柱(100 mm×2.1 mm,1.7μm),以0.1%甲酸水溶液-乙腈为流动相进行梯度洗脱。在电喷雾离子源(electrospray ionization,ESI+)模式下,采用MS^E采集模式,对待测未知杂质进行定性研究和分子量准确测定,初步确定杂质的结构。通过加速稳定性实验以及ICP-MS/MS、ICP-AES考察杂质与主药和处方中辅料的相关性。结果显示,某企业处方中加入了辅料依地酸二钠,反而与主药卡铂相互作用,生成含铂有关物质,从而导致卡铂降解产生更多的1,1-环丁烷二羧酸。因此,本研究表明依地酸二钠的添加加剧了卡铂注射液有关物质的增加,辅料添加的合理性值得进一步关注。
