项目摘要
Damage to or loss of the peripheral axons of primary sensory neurons is associated with two clinical syndromes: peripheral neuropathic pain and peripheral neuropathy. Treatment for neuropathic pain is typically ineffective or associated with side effects, and there is no treatment for peripheral neuropathy. To remedy this, it is essential that the mechanisms responsible for both are understood and targets identified that could be amenable to development of novel therapeutics. My goal is to dissect out at an individual neuron level the transcriptional and functional changes that occur over time in response to physical axonal injury, ion channel mutations and exposure to neurotoxic cancer chemotherapeutic agents, and explore the extent to which hyperexcitability and axon degeneration are linked. This will involve combinations of several different approaches: correlating single cell profiles and disease related functional changes, identifying disease susceptibility in patient stem derived neurons, high content phenotypic screens, population imaging in intact animals, genetic editing, and interrogation at high temporal and spatial resolution of behavioral surrogates of pain and sensory loss. The project will focus on neuropathic pain due to physical disruption of peripheral sensory axons, small fiber neuropathies due to voltage-gated sodium channel mutations and chemotherapy- induced peripheral neuropathy, and will examine if these syndromes are distinct or part of a spectrum of sensory neuron pathologies with overlapping risk factors and mechanisms.
初级感觉神经元外周轴突的损伤或丧失与两种临床综合征相关:外周神经性疼痛和外周神经性病变。神经性疼痛的治疗通常无效或伴有副作用,周围神经病变没有治疗方法。为了解决这个问题,至关重要的是要了解两者的作用机制,并确定可用于开发新疗法的靶点。我的目标是在单个神经元水平上解剖随着时间的推移而发生的转录和功能变化,以响应物理轴突损伤,离子通道突变和暴露于神经毒性癌症化疗药物,并探索过度兴奋性和轴突变性之间的联系程度。这将涉及几种不同方法的组合:将单细胞谱和疾病相关的功能变化相关联,识别患者干细胞来源的神经元中的疾病易感性,高含量表型筛选,完整动物的群体成像,基因编辑,以及在高时空分辨率下对疼痛和感觉丧失的行为替代品进行询问。该项目将重点关注外周感觉轴突物理破坏引起的神经性疼痛、电压门控钠通道突变引起的小纤维神经病变和化疗引起的外周神经病变,并将研究这些综合征是不同的,还是具有重叠危险因素和机制的感觉神经元病变的一部分。
