Optimized Immunostaining of Embryonic and Early Postnatal Mouse Brain Sections

[Abstract]  

The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded transcription factors and molecular determinants that define the identity of different projection neurons. Thus, specific detection and visualization of protein expression is crucial for assessing the identity of neocortical neurons and, more broadly, for understanding early and late developmental mechanisms and function of this complex system. Several immunostaining/immunofluorescence methods exist to detect protein expression. Published protocols vary with regard to subtle details, which may impact the final outcome of the immunofluorescence.

Bioluminescence Monitoring of Neuronal Activity in Freely Moving Zebrafish Larvae

[Abstract]  The proof of concept for bioluminescence monitoring of neural activity in zebrafish with the genetically encoded calcium indicator GFP-aequorin has been previously described (Naumann et al., 2010) but challenges remain. First, bioluminescence signals originating from a single muscle fiber can constitute a major pitfall. Second, bioluminescence signals emanating from neurons only are very small. To improve signals while verifying specificity, we provide an optimized 4 steps protocol achieving: 1) selective expression of a zebrafish codon-optimized GFP-aequorin, 2) efficient soaking of larvae in GFP-aequorin substrate coelenterazine, 3) bioluminescence monitoring of neural activity from motor neurons in free-tailed moving animals performing acoustic ... [摘要]  以前已经描述了基因编码的钙指示剂GFP-aequorin的斑马鱼中神经活性的生物发光监测的概念验证(Naumann等人,2010),但是仍然存在挑战。 首先,源自单一肌纤维的生物发光信号可能构成主要缺陷。 第二,仅从神经元发出的生物发光信号非常小。 为了改善信号,同时验证特异性,我们提供了一个优化的4步骤协议,实现:1)选择性表达斑马鱼密码子优化的GFP水母发光蛋白,2)在GFP-水母发光蛋白底物coelenterazine中有效浸泡幼虫3)生物发光监测神经活动 来自运动神经元的自由运动的动物执行声学逃逸和4)使用免疫组织化学验证肌肉的表达缺乏。
【背景】不同于荧光基因编码的钙指示剂(GECIs)(Grienberger和Konnerth,2012),如GCaMP家族,生物发光指示剂GFP-水母发光蛋白(Shimomura等,1962)不需要光激发,因此开启了监测神经元的新途径包括苍蝇在内的动物(Martin等,2007),小鼠(Rogers et al。,2007)和斑马鱼幼虫(Naumann et ...

[Abstract]  The Drosophila melanogaster trachea is a branched network of rigid chitin-lined tubes that ramify throughout the body and functions as the fly’s respiratory organ. Small openings at the ends of the tracheal tubes allow gas exchange to occur by diffusion between internal tissues and the exterior environment. Tracheal tubes are lined by a single layer of epithelial cells, which secrete chitin and control tube morphology and size. Studies of tracheal development in Drosophila embryos have elucidated fundamental mechanisms of tube morphogenesis and maintenance in vivo, and identified major signaling pathways that regulate these processes (Manning and Krasnow, 1993; Affolter and Shilo, 2000; Zuo et al., 2013; Kerman et al., ...
