肿瘤微环境中骨髓来源的细胞将肿瘤抗原呈递给免疫T细胞的性质和位点仍然没有解决。我们生成了自发性免疫逃避性乳腺癌的荧光小鼠模型,并鉴定了与树突状细胞和巨噬细胞具有显著相似性的髓样细胞亚群,其组成性摄取肿瘤衍生蛋白并将加工的肿瘤抗原呈递给反应性T细胞。使用活体活体成像,我们确定浸润的肿瘤特异性T细胞与这些细胞在肿瘤附近进行长期相互作用。在体外,这些细胞捕获细胞毒性T细胞的信号转导能力的共轭物,但不支持完全激活或维持细胞溶解。时空动力学揭示了肿瘤边缘T细胞和抗原呈递细胞之间的非生产性相互作用。
The nature and site of tumor-antigen presentation to immune T cells by bone-marrow-derived cells within the tumor microenvironment remains unresolved. We generated a fluorescent mouse model of spontaneous immuno-evasive breast cancer and identified a subset of myeloid cells with significant similarity to dendritic cells and macrophages that constitutively ingest tumor-derived proteins and present processed tumor antigens to reactive T cells. Using intravital live-imaging, we determined that infiltrating tumor-specific T cells engage in long-lived interactions with these cells, proximal to the tumor. In vitro, these cells capture cytotoxic T cells in signaling-competent conjugates, but do not support full-activation or sustain cytolysis. The spatiotemporal dynamics revealed here implicate non-productive interactions between T cells and antigen presenting cells on the tumor margin.
