项目摘要
In this study, we tried to reveal the molecular and cellular mechanisms of activation of anti-tumor immunity by CD169-positive macrophages located in lymph node sinus. We generated CD169-Cre-YFP mice, in which CD169-positive macrophages were specifically labeled with YFP, and examined the character of these cells using the mice. We also identified CD169 macrophages-producing molecules that may be able to activate anti-tumor immunity. We established an experimental model to induce cell death of tumor cells in tumor-bearing mice, found the drastic changes in tumor-associated macrophages after tumor cell death. We also reveal the roles of CD169 macrophages in the immune regulation in non-immune tissues.
在本研究中,我们试图揭示位于淋巴结窦的CD169阳性巨噬细胞激活抗肿瘤免疫的分子和细胞机制。我们生成了 CD169-Cre-YFP 小鼠,其中 CD169 阳性巨噬细胞被 YFP 特异性标记,并使用小鼠检查了这些细胞的特征。我们还鉴定了产生 CD169 巨噬细胞的分子,这些分子可能能够激活抗肿瘤免疫。我们建立了诱导荷瘤小鼠肿瘤细胞死亡的实验模型,发现肿瘤细胞死亡后肿瘤相关巨噬细胞发生了剧烈变化。我们还揭示了 CD169 巨噬细胞在非免疫组织的免疫调节中的作用。
