Tumor immune escape is a critical trait of cancer but the mechanisms involved have yet to fully emerge. One recent study has shown that tumor cells can escape T-cell immunity by overexpressing the endothelial cell adhesion molecule vascular cell adhesion molecule-1 (VCAM-1), which normally mediates leukocyte extravasion to sites of tissue inflammation. Renal cell carcinoma (RCC) was identified as one tumor type where VCAM-1 is commonly highly overexpressed. Together, our findings suggest that RCCs might exploit VCAM-1 overexpression for immune escape.
肿瘤免疫逃逸是癌症的一个关键特征,但其涉及的机制尚未完全明确。最近的一项研究表明,肿瘤细胞可通过过度表达内皮细胞粘附分子血管细胞粘附分子-1(VCAM-1)来逃避T细胞免疫,该分子通常介导白细胞外渗至组织炎症部位。肾细胞癌(RCC)被确定为一种VCAM-1通常高度过度表达的肿瘤类型。综合来看,我们的研究结果表明,肾细胞癌可能利用VCAM-1的过度表达来实现免疫逃逸。
