We hypothesise that mitochondrial complex I inhibition (via knock down of subunit ND-75) will lead to distinct transcriptional and functional stress responses in different neuronal subtypes. To test this hypothesis in the next upcoming months I plan to:1. Analyze the behavioural effects of ND-75 KD in a single neuronal subtype, dopaminergic and serotonergic neurons.Climbing and seizure assaysCAFÉ feeding assayANY-Maze open field assayHot plate assayAnalysis of ATF4 expression- adult brain dissections, staining and confocal microscopy 2. Analyze the transcriptional response caused by ND-75 KD in single neurons. -We will perform single nuclear RNA-seq (snRNA-seq) from flies with pan-neuronal ND-75 KD and ND-75 KD together with ATF4 KD.3. Test whether targeting mitochondrial stress signalling modifies dopaminergic and serotonergic neuron function.

我们假设线粒体复合体I抑制（通过敲低亚基ND-75）将导致不同神经元亚型中不同的转录和功能应激反应。为了在接下来的几个月里验证这个假设，我计划：分析nd - 75kd对单一神经元亚型，多巴胺能神经元和血清素能神经元的行为影响。攀爬和癫痫assaysCAFÉ喂食实验anyy -迷宫空旷区实验热板实验ATF4表达分析-成人脑切片，染色和共聚焦显微镜分析nd - 75kd对单个神经元的转录反应。我们将对携带泛神经元ND-75 KD和ND-75 KD以及ATF4 KD的果蝇进行单核rna测序（snrna测序）。测试是否靶向线粒体应激信号改变多巴胺能和血清素能神经元功能。
