柯萨奇病毒和腺病毒受体(CAR)是一种膜糖蛋白,具有胞质结构域、跨膜结构域和胞外区域,由两个免疫球蛋白样结构域组成,一个是氨基末端免疫球蛋白变量(IgV)相关结构域(D1),位于细胞表面的远端,另一个是近端IgC2结构域(D2)。柯萨奇病毒和腺病毒受体已被证明在人类膀胱和前列腺癌细胞中表现出肿瘤抑制活性。在当前的论文中,我们证明了CAR在胶质瘤细胞中是一种肿瘤抑制因子,并且这种抑制作用不需要细胞外D2结构域。这一发现为CAR在恶性胶质瘤细胞中的表达下调提供了生物学基础。这表明,为了实现腺病毒载体在癌症基因治疗中的全部潜力,将有必要重新定向腺病毒以实现car非依赖性感染。
The coxsackievirus and adenovirus receptor (CAR) is a membrane glycoprotein with a cytoplasmic domain, a transmembrane domain and an extracellular region consisting of two immunoglobulin-like domains, an amino-terminal immunoglobulin variable (IgV)-related domain (D1), which is distal to the cell surface, and a proximal IgC2 domain (D2). The coxsackievirus and adenovirus receptor has been shown to exhibit tumour suppression activity in human bladder and prostate cancer cells. In the current paper, we demonstrate that CAR is a tumour suppressor in glioma cells and that the extracellular D2 domain is not required for this inhibitory effect. This finding provides a biological basis for the observation that expression of CAR is downregulated in malignant glioma cells. This suggests that strategies to redirect adenoviruses to achieve CAR-independent infection will be necessary to realise the full potential of adenoviral vectors for cancer gene therapy.
