年龄相关性黄斑变性(AMD)是人类视力丧失的主要原因。尽管其患病率和医学意义,AMD的许多方面仍然难以捉摸,治疗选择有限。在这里,我们提供的数据表明跳蛛为了解视网膜变性的基本原理提供了一个独特的机会,从而揭示了一个影响全球数百万人的过程。使用显微检眼镜和组织学证据,我们证明,显着的感光细胞损伤可以发生在发展过程中的成像前外侧眼的跳跃spiderPhidippus audax。此外,我们发现这种光感受器退化会因营养不足而加剧,并且在视网膜的高密度区域最为普遍,如人类的AMD。这表明,与脊椎动物相似,视网膜在P。Audax面临着满足高能量蜂窝需求的挑战。
Age-related macular degeneration (AMD) is a leading cause of vision loss in humans. Despite its prevalence and medical significance, many aspects of AMD remain elusive and treatment options are limited. Here, we present data that suggest jumping spiders offer a unique opportunity for understanding the fundamentals underlying retinal degeneration, thereby shedding light on a process that impacts millions of people globally. Using a micro-ophthalmoscope and histological evidence, we demonstrate that significant photoreceptor damage can occur during development in the image-forming anterior lateral eyes of the jumping spiderPhidippus audax. Furthermore, we find that this photoreceptor degeneration is exacerbated by inadequate nutrition and is most prevalent in the high-density region of the retina, like AMD in humans. This suggests that similar to those in vertebrates, the retinas inP. audaxare challenged to meet high-energy cellular demands.
