研究人员目前正在进一步优化芯片的稳定性与重复性，希望能将其投入到新型呼吸道病原体的早期检测 中。 新华社耶路撒冷12月14日电（记者王卓伦 路一凡）以色列魏茨曼科学研究所日前发布公报说，该所研 究人员开发出一种无细胞生物芯片，未来可用于新发病毒的早期抗体快速筛查、候选疫苗抗体活性比较 等。 公报说，传统的病毒抗体研究通常需要在实验室里逐步完成病毒蛋白的表达、纯化，再利用酶联免疫吸 附试验等方法分析抗体反应，整个流程耗时较长、步骤复杂。面对快速传播的新发病毒，研究人员常难 以及时开展大规模蛋白筛选和免疫学分析。 这种新型生物芯片基于基因编程，每个生物芯片可携带30至40个特定病毒蛋白或片段。仅需不到一滴 血，就可以揭示一个人在几十个病毒目标或抗原上的免疫"指纹"。由于每种抗原出现在芯片上的不同位 置，研究人员可以分别测量与每种抗原结合的抗体数量。 实验结果显示，与传统的标准酶联免疫吸附试验相比，这种芯片可检测到传统方法无法检测到的更微妙 的抗体反应。 相关成果已发表在英国《自然·纳米技术》杂志上。（完） ...

Core Viewpoint - The article discusses a significant advancement in the field of neuroscience, specifically the successful creation of human sympathetic ganglia organoids (hSGO) from human pluripotent stem cells (hPSC), which can be integrated with human heart organoids (hHFO) to form a human sympathetically innervated heart organoid (hSHO) [1][6]. Group 1: Research Background - The sympathetic ganglia are a crucial component of the peripheral nervous system (PNS) and play an essential role in maintaining homeostasis [4]. - Previous attempts to create organoids representing the peripheral nervous system have been limited, particularly in mimicking the self-organizing development of sympathetic ganglia [5]. Group 2: Research Methodology - The research team utilized directed 3D differentiation techniques from human pluripotent stem cells to develop a method for generating human sympathetic ganglia organoids (hSGO), which exhibit directed and self-organizing sympathetic neuronal differentiation [5]. - The hSGO produced sympathetic neurons and glial cells, demonstrating functional development over long-term culture [5]. Group 3: Key Findings - By fusing hSGO with hHFO, the researchers successfully recreated the functional sympathetic innervation of the human heart, resulting in the formation of hSHO [6]. - The hSHO model allows for the evaluation of factors regulating sympathetic innervation of the heart, such as nerve growth factor signaling, and reveals that inter-tissue interactions influence the development of both sympathetic nerves and the heart [6].
