Chemokines are important components of cancer-related inflammation. In this issue of Cancer Cell, Chen et al. report that the chemokine CCL18, produced by tumor-associated macrophages, promotes malignant behavior and correlates with metastasis in human breast cancer. Unexpectedly, PITPNM3/Nir1, a molecule unrelated to chemokine receptors, was identified as its elusive receptor.
趋化因子是癌症相关炎症的重要组成部分。在本期《癌细胞》中,Chen 等人报告称,趋化因子 CCL18 由肿瘤相关巨噬细胞产生,可促进恶性行为,并与人类乳腺癌的转移相关。出人意料的是,一种与趋化因子受体无关的分子 PITPNM3/Nir1 被鉴定为其难以捉摸的受体。
