秀丽隐杆线虫具有与温度习惯相关的耐冷能力,该耐冷能力由头部的一对 ASJ 温度传感神经元控制。最近的表型分析表明,改变培养温度后的 3-5 小时内,耐寒性的温度经验可以被覆盖。因此,长期测量 ASJ 神经元的神经活动对于进行耐冷性的量化分析非常重要。在这里,我们展示了使用基因编码的钙指示剂 Cameleon 对 ASJ 神经元活动进行长期成像的详细方案。
Caenorhabditis elegans has temperature habituation-linked cold tolerance that is controlled by a pair of ASJ temperature sensing neurons in the head. Recent phenotypic analyses showed that temperature experience for cold tolerance can be overwritten within 3–5 h after cultivation temperature is altered. Therefore, long-term measurement of neuronal activity of ASJ neurons is considered important to perform quantification analysis in cold tolerance. Here we show a detailed-protocol for long-term imaging of ASJ neuronal activity by using a genetically encoded calcium indicator cameleon.
