Abstract

Epidermal growth factor receptor (EGFR) is known to be critically involved in tissue development and homeostasis as well as in the pathogenesis of cancer. Here we showed that Foxp3(+) regulatory T (Treg) cells express EGFR under inflammatory conditions. Stimulation with the EGF-like growth factor Amphiregulin (AREG) markedly enhanced Treg cell function in vitro, and in a colitis and tumor vaccination model we showed that AREG was critical for efficient Treg cell function in vivo. In addition, mast cell-derived AREG fully restored optimal Treg cell function. These findings reveal EGFR as a component in the regulation of local immune responses and establish a link between mast cells and Treg cells. Targeting of this immune regulatory mechanism may contribute to the therapeutic successes of EGFR-targeting treatments in cancer patients.

摘要

表皮生长因子受体 (EGFR) 已知在组织发育和稳态以及癌症的发病机制中起着关键作用。在这里,我们表明 Foxp3(+)调节性 T (Treg) 细胞在炎症条件下表达 EGFR。用 EGF 样生长因子 Amphiregulin (AREG) 刺激显着增强了 Treg 细胞在体外的功能,并且在结肠炎和肿瘤疫苗模型中,我们表明 AREG 对于 Treg 细胞在体内的有效功能至关重要。此外,肥大细胞衍生的 AREG 完全恢复了最佳的 Treg 细胞功能。这些发现揭示了 EGFR 是局部免疫反应调节的一个组成部分,并建立了肥大细胞和 Treg 细胞之间的联系。针对这种免疫调节机制可能有助于 EGFR 靶向治疗在癌症患者中的治疗成功。
