在分子成像领域,对靶细胞的选择性是成像对比度程度的关键决定因素。之前,我们开发了一种预靶向方法,通过该方法,可以使用标记的n-聚糖选择性地对靶细胞进行成像,该n-聚糖与细胞表面的整合素靶向环RGD肽原位连接。在这里,我们证明了我们的方法在区分各种癌细胞和非癌细胞方面的能力,这些细胞不能用传统的RGD配体来区分。利用四种不同连接长度的RGDyK环肽与五种n -聚糖,我们确定了在96孔板上区分六种表达αvβ3整合素的细胞的最佳组合。将靶细胞的RGD和n -聚糖配体的最佳组合指纹印在板上,然后用于异种移植小鼠模型的肿瘤选择性成像。利用这种方法,各种n -聚糖分子,甚至是那些与其同源凝集素具有毫摩尔亲和力的n -聚糖分子,都可以用于选择性癌细胞分化。肿瘤细胞表达高水平的整合素,可以使用环肽标记,但选择性标记靶细胞可能是一个挑战。在这里,强结合环肽与弱结合聚糖的原位连接可以区分癌细胞和非癌细胞,它们都在表面表达整合素。
In the field of molecular imaging, selectivity for target cells is a key determinant of the degree of imaging contrast. Previously, we developed a pre-targeted method by which target cells could be selectively imaged using a labeled N-glycan that was ligated in situ with an integrin-targeted cyclic RGD peptide on the cell surface. Here we demonstrate the power of our method in discriminating various cancerous and non-cancerous cells that cannot be distinguished using conventional RGD ligands. Using four cyclic RGDyK peptides with various linker lengths with five N-glycans, we identify optimal combinations to discriminate six types of αvβ3 integrin–expressing cells on 96-well plates. The optimal combinations of RGD and N-glycan ligands for the target cells are fingerprinted on the plates, and then used to selectively image tumors in xenografted mouse models. Using this method, various N-glycan molecules, even those with millimolar affinities for their cognate lectins, could be used for selective cancer cell differentiation. Tumor cells express high levels of integrins, which can be labeled using cyclic peptides, but selective labeling of target cells can be a challenge. Here in situ ligation of strongly binding cyclic peptides with weakly binding glycans allows discrimination of cancerous and non-cancerous cells which both express integrins on the surface.
