We recently conducted a study that aimed to describe the differentiation mechanisms used to generate O2 and CO2 sensing neurons in C. elegans. We identified egl-13/Sox5 to be required for the differentiation of both O2 and CO2 sensing neurons. We found that egl-13 functions cell autonomously to drive O2 and CO2 sensing neuron fate and is therefore essential for O2 and CO2 sensing-induced behaviors. Through systematic dissection of the egl-13 promoter we identified upstream regulators of egl-13 and proposed a model of how differentiation of O2 and CO2 sensing neurons is regulated. In this commentary we discuss our findings and open questions we wish to address in future studies.
我们最近开展了一项研究,旨在描述秀丽隐杆线虫中用于生成氧气和二氧化碳感知神经元的分化机制。我们确定egl-13/Sox5是氧气和二氧化碳感知神经元分化所必需的。我们发现egl-13在细胞自主发挥作用,以驱动氧气和二氧化碳感知神经元的命运,因此对于氧气和二氧化碳感知诱导的行为至关重要。通过对egl-13启动子的系统剖析,我们确定了egl-13的上游调节因子,并提出了一个关于氧气和二氧化碳感知神经元分化如何受到调控的模型。在这篇评论中,我们讨论了我们的研究结果以及我们希望在未来研究中解决的开放性问题。
