Abstract

Biallelic mutations in AP4S1, the σ4 subunit of the adaptor protein complex 4 (AP-4), lead to autosomal recessive spastic paraplegia 52 (SPG52). It is a subtype of AP-4-associated hereditary spastic paraplegia (AP-4-HSP), a complex childhood-onset neurogenetic disease characterized by progressive spastic paraplegia of the lower limbs. This disease has so far lacked effective treatment, in part due to a lack of suitable animal models. Here, we used CRISPR/Cas9 technology to generate a truncation mutation in the ap4s1 gene in zebrafish. The ap4s1 truncation led to motor impairment, delayed neurodevelopment, and distal axonal degeneration. This animal model is useful for further research into AP-4 and AP-4-HSP.

Ap4s1截短导致斑马鱼痉挛性截瘫模型中的轴突缺陷52。

衔接蛋白复合体4（AP-4）的σ4亚基AP4S1的双等位基因突变导致常染色体隐性痉挛性截瘫52（SPG52）。它是AP-4相关遗传性痉挛性截瘫（AP-4-HSP）的一种亚型，是一种以进行性下肢痉挛性截瘫为特征的复杂的儿童期神经源性疾病。到目前为止，这种疾病还缺乏有效的治疗方法，部分原因是缺乏合适的动物模型。在这里，我们使用CRISPR/Cas9技术在斑马鱼的ap4s1基因中产生了一个截短突变。ap4s1截短导致运动障碍、神经发育迟缓和远端轴突变性。该动物模型可用于进一步研究AP-4和AP-4-HSP。

期刊介绍： International Journal of Developmental Neuroscience publishes original research articles and critical review papers on all fundamental and clinical aspects of nervous system development, renewal and regeneration, as well as on the effects of genetic and environmental perturbations of brain development and homeostasis leading to neurodevelopmental disorders and neurological conditions. Studies describing the involvement of stem cells in nervous system maintenance and disease (including brain tumours), stem cell-based approaches for the investigation of neurodegenerative diseases, roles of neuroinflammation in development and disease, and neuroevolution are also encouraged. Investigations using molecular, cellular, physiological, genetic and epigenetic approaches in model systems ranging from simple invertebrates to human iPSC-based 2D and 3D models are encouraged, as are studies using experimental models that provide behavioural or evolutionary insights. The journal also publishes Special Issues dealing with topics at the cutting edge of research edited by Guest Editors appointed by the Editor in Chief. A major aim of the journal is to facilitate the transfer of fundamental studies of nervous system development, maintenance, and disease to clinical applications. The journal thus intends to disseminate valuable information for both biologists and physicians. International Journal of Developmental Neuroscience is owned and supported by The International Society for Developmental Neuroscience (ISDN), an organization of scientists interested in advancing developmental neuroscience research in the broadest sense.
