项目摘要
DESCRIPTION (provided by applicant): Human brain complexity is considered unique, yet the genesis of many neuronal and glial sub-types and their migration and integration into functional circuits in neonates remains poorly understood. Moreover, these processes are likely disrupted in hypoxic neurological injuries, which can result in death, cerebral palsy and/or long-term cognitive disabilities. The proposed program focuses on human interneuron (IN) and oligodendrocyte precursor (OPC) development during 3rd trimester (24-40 weeks) gestation, and whether lineage ontogeny, migration and differentiation is regulated by oxygen levels and the hypoxia-inducible factor (HIF) pathway. This program is an outgrowth of the investigators common interests, productive collaborations and the close association of their laboratories in the recently built Ray and Dagmar Dolby Building in the Eli and Edythe Broad Institute for Regeneration Medicine and Stem Cell Research at UCSF. The investigators have studied the human fetal and newborn brain and recently identified (1) the outer subventricular zone (OSVZ), (2) chain migration of young neurons of medial migratory stream (MMS) and (3) the impact of injury on oligodendrocyte development in infants with hypoxic-ischemic encephalopathy (HIE). We propose three projects and cores to promote an understanding of human brain development and injury. Project 1 investigates migration of young INs to focal regions of human newborn brain, their differentiation and the developmental impact of oxygen- regulated pathways. Project 2 will define structure and OPC production of the human OSVZ from 24-40 weeks gestation, and regulation of lineage ontogeny by oxygen levels. Project 3 will provide direct evidence for HIF pathway activation in IN and OPC populations in human neonates with HIE, and cell-intrinsic functions of HIF pathway genes during pre- and post-natal IN and OPC development. The administrative core (A) provides budgetary oversight, coordination and access to resources. All projects will use primary human neuropathological specimens for histological analysis supported by a neuropathology core (B). All projects will employ animal experimental systems. Based on compelling preliminary data, we propose an animal model core (C) to support studies in neonatal ferret brain.
描述(由申请人提供): 人类大脑的复杂性被认为是独特的,但许多神经元和神经胶质亚型的起源及其迁移和整合到新生儿的功能回路仍然知之甚少。此外,这些过程可能在缺氧性神经损伤中被破坏,这可能导致死亡,脑瘫和/或长期认知障碍。该计划的重点是人类中间神经元(IN)和少突胶质细胞前体(OPC)在妊娠第三个月(24-40周)的发展,以及是否谱系个体发育,迁移和分化是由氧水平和缺氧诱导因子(HIF)途径调节。该计划是研究人员共同利益,富有成效的合作以及他们在最近建造的Eli和Edythe Broad再生医学和干细胞研究所的Ray和Dagmar Dolby大楼实验室的密切联系的产物。研究人员研究了人类胎儿和新生儿的大脑,最近确定了(1)外侧脑室下区(OSVZ),(2)内侧迁移流(MMS)年轻神经元的链迁移和(3)损伤对缺氧缺血性脑病(HIE)婴儿少突胶质细胞发育的影响。我们提出了三个项目和核心,以促进对人类大脑发育和损伤的理解。项目1研究了年轻IN向人类新生儿大脑焦点区域的迁移,它们的分化以及氧调节途径对发育的影响。项目2将定义从妊娠24-40周的人OSVZ的结构和OPC产生,以及通过氧水平调节谱系个体发育。项目3将提供HIF途径在患有HIE的人类新生儿的IN和OPC群体中激活的直接证据,以及HIF途径基因在出生前和出生后IN和OPC发育期间的细胞内在功能。行政核心(A)提供预算监督、协调和获得资源的机会。所有项目将使用原始人类神经病理学标本进行组织学分析,并由神经病理学核心(B)支持。所有项目都将采用动物实验系统。基于令人信服的初步数据,我们提出了一个动物模型核心(C),以支持新生雪貂脑的研究。
