巨噬细胞可占肿瘤质量的50%,并分泌许多血管生成因子。此外,肿瘤缺氧被认为在巨噬细胞的激活和血管生成的调节中起主要作用。在这篇文章中,我们证明了在8个实验肿瘤中,低氧与免疫细胞与免疫球蛋白结合的募集有很强的相关性。我们提供的证据表明,在3个肿瘤细胞系中,免疫细胞主要由巨噬细胞组成。氧合减少可能刺激免疫细胞向肿瘤组织募集,检测免疫球蛋白阳性宿主细胞或巨噬细胞可能为监测肿瘤缺氧提供一种替代方法。©2001癌症研究活动http://www.bjcancer.com
Macrophages can account for up to 50% of tumour mass and secrete many angiogenic factors. Furthermore, tumour hypoxia is thought to play a major role in the activation of macrophages and the regulation of angiogenesis. In this paper, we demonstrate a strong correlation between hypoxia and the recruitment of immune cells binding to IgG in 8 experimental tumours. We provide evidence that IgG binding immune cells in 3 tumour lines are predominately composed of macrophages. Reduced oxygenation may act as a stimulus for recruitment of immune cells to the tumour mass, and the detection of either IgG-positive host cells or macrophages may offer an alternative method for monitoring tumour hypoxia. © 2001 Cancer Research Campaign http://www.bjcancer.com
