纳米抗体研究进展综述摘要：单域抗体因其独特的优势，如水溶性好、分子量小、稳定性好、免疫原性小等一系列特点，在生物研究和医学领域中的作用愈发广泛。

在疾病诊断、病原检测、癌症疾病治疗、药物残留检测分析，坏境检测，用作sdAbs分子探针、分子诊断和显影等等领域具有广阔的应用前景。

纳米抗体因其优势，可实现重组表达，从而使得生产周期和生产成本均可大幅下降，是目前国内外研发的热点。

作者重点介绍了纳米抗体的特点，然后简述了纳米抗体的制备流程，简述了纳米抗体在疾病诊断、疾病治疗、食品安全和环境监测等领域的应用，最后对纳米抗体的应用前景进行了分析和展望。

1 介绍自1890年，第一种抗体——抗毒素，这是在血清中发现的第一种抗体［１］。

这是一种可中和外毒素的物质，1975年，杂交瘤技术的诞生开始了抗体研究和应用快速发展的时代。

由于抗体可特异性识别和结合抗原的特性，使其在疾病诊断、疾病治疗、药物运载、病原、毒素和小分子化合物检测等领域具有广泛的应用［２］。

但通过单克隆抗体技术制备的传统单克隆抗体有其不可忽视的缺点：生产耗时长、成本高、在组织和肿瘤中穿透力差、长期使用会引起机体免疫排斥反应以及动物道德问题等。

相比于传统抗体，纳米抗体具备传统抗体不具备的分子质量小和穿透性强的优势而成为现在抗体研究的主要方向之一。

单链抗体（single chain antibody fragment,scFv）就是新型小分子抗体的一种，其穿透力更强、生产成本更低，但scFv抗体存在溶解度低、稳定性较差、表达量低、易聚合和亲和力低的缺点［３］。

1989年，比利时免疫学家Hamers-Casterman 在骆驼血清中的偶然发现一种天然缺失轻链的重链抗体（HcAbs）可以解决scFv所存在的问题，重链抗体只包含２个常规的CH2与CH3区和１个重链可变区（ＶＨＨ），重链可变区具有与原重链抗体相当的结构稳定性以及与抗原的结合活性，是已知的可结合目标抗原的最小单位，其分子质量只有单克隆抗体的1/10，是迄今为止获得的结构稳定且具有抗原结合活性的最小抗体单位，因此也被称作纳米抗体（nanobody,Nb）［４］。

内基小体的名词解释

内基小体的名词解释内基小体（Nanobodies）是一种新兴的单链抗体分子，由于其小尺寸、稳定性和多样性等特点，在科研领域引起了广泛的关注和应用。

本文将对内基小体进行详细的名词解释，探讨其独特的结构和功能，以及在医学、生物技术和药物研发中的应用前景。

一、内基小体的定义和来源内基小体，又称VHH抗体，是一类由于小鼠等齐蹄动物体内特殊的抗体分子产生机制产生的特异性结合相应抗原的单链抗体。

内基小体的结构特征是其抗原结合衍生物为单单链抗体。

内基小体作为一种天然存在的抗体碎片，它来源于鼠科动物的免疫系统，尤其是杜波伊斯黄白鼠（Camelidae），其内毒素（IgG）的VH抗体链存在类似抗体特异性表达的低亲和度抗体。

通过在免疫响应中选择性繁殖抗体相关的基因刺激，研究人员可以通过长时间进化实验获得特异性的内基小体。

二、内基小体的结构和功能与传统的抗体相比，内基小体具有独特的结构和功能。

内基小体由单一的可变区域域组成，这意味着它们体积相对较小，通常只有15千达尔顿（kDa）左右。

相比之下，典型的抗体可重组片段（Fab）大小约为50 kDa。

内基小体也被称为天然的“单一域”抗体，因为它们的可变区域仅包含一个可变区域域，而不像传统抗体那样包含VH和VL两个可变区域。

这使得内基小体的结构更简单，更容易表达和扩增。

尽管内基小体的大小比传统抗体小，但它们的亲和力和特异性仍然非常高。

这使得内基小体成为一种理想的工具来探索和专注于特定的抗原。

三、内基小体在医学领域的应用内基小体在医学研究领域有着广泛的应用前景。

首先，内基小体具有很好的渗透能力，能够穿透组织和器官，与潜在的抗原结合，从而成为药物运输的理想选择。

其次，内基小体在抗肿瘤治疗中具有重要的作用。

通过突变内基小体的结构，研究人员可以使其特异性结合癌细胞表面的抗原，从而实现精准的治疗。

此外，结合放射性元素或药物的内基小体也可以用于纳米医学和肿瘤成像。

除了抗肿瘤治疗外，内基小体还可以用于治疗其他疾病，如自身免疫性疾病、炎症性疾病和感染性疾病等。

【高中生物】Nature Methods新年展望：新蛋白标记

【高中生物】Nature Methods新年展望：新蛋白标记今年第一期《NatureMethods》评出了2021的年度技术??单颗粒冷冻电镜（cryo-EM）。

除此之外，该杂志还对一些热门技术进行了一番展望，包括细胞内蛋白标记、精准光遗传学、高度多重成像、亚细胞图谱分析等等。

荧光化学染料相对较小，具有很好的光物理性质和光谱跨度。

这些特性使荧光染料特别有吸引力，有望替代荧光蛋白进行蛋白标记。

研究者们正在积极开发相应的工具，在活细胞中用染料标记目的蛋白。

对于绝大多数应用来说，荧光染料需要能够实现特异性的标记。

现在已经有一些工具能做到这一点，比如SNAP和Halo标签、FlAsH和ReAsH、和hexahistidine标签。

这些工具主要使用能特异性结合相应染料的小蛋白或多肽，对靶蛋白进行标记。

还有一种方法是在蛋白翻译过程中掺入非天然氨基酸，这些非天然氨基酸本身就发荧光，或者可以通过点击化学（clickchemistry）发出荧光。

（延伸阅读：NatureMethods发表新荧光标记技术）虽然这些方法越来越受欢迎，但它们也遇到了一些问题。

举例来说，荧光染料在多重成像中用处有限，能跨越活细胞膜的染料标记效率低、数量少、质量差。

这类染料的开发目前是一个相当活跃的研究领域。

毫无疑问，未来人们将大大增强荧光染料的标记效率，这会进一步提高定量成像的能力。

可用染料将得到显著改进，这会增加多重化，减少成像所需的光。

全新的蛋白标记方法也将出现在人们眼前。

特异性蛋白标记有助于在固定细胞和活细胞中进行超高分辨率成像。

当分辨率接近几十纳米的时候，标记造成的问题就会凸现出来。

举例来说，用抗体进行标记会使目标结构增加约10nm，而二抗会进一步增大检测目标。

为了解决这一问题，不少研究者正在开发纳米抗体（nanobodies）。

纳米抗体是来自骆驼的小抗体片段，是人们用基因工程方法克隆骆驼重链抗体可变区得到的单域抗体。

与传统IgG抗体相比，纳米抗体具有分子质量小、容易生产、稳定性好、抗原结合力高等特点。
