    • Toll-like receptor (TLR) agonists can induce chemokine production. We find that TLR2 and TLR6 are widely expressed on human melanoma cells, and that TLR2/6 agonists (MALP-2 or FSL-1) synergize with interferon-gamma (IFN to induce production of CXCL10 from melanoma cells. Furthermore, melanoma cells and immune cells freshly isolated from surgical specimens also respond to TLR2/6 agonists +IFN by upregulating CXCL10 production, compared to treatment with either agent alone. It is also disclosed herein that these compounds are useful in inducing CLXL10 in other types of cancer. Collectively, these data identify a novel synergy of TLR2/6 agonists +IFN for inducing CXCL10 production directly from melanoma cells, raising the possibility that intratumoral administration of these agents may improve immune signatures in melanoma and have value in combination with other immune therapies, by supporting T-cell migration into melanoma metastases.
    • Toll样受体(TLR)激动剂可诱导趋化因子产生。 我们发现TLR2和TLR6在人黑素瘤细胞中广泛表达,TLR2 / 6激动剂(MALP-2或FSL-1)与干扰素-γ(IFNγ)协同作用诱导黑素瘤细胞产生CXCL10。 此外,与单独使用任一试剂的治疗相比,从外科手术标本新鲜分离的黑素瘤细胞和免疫细胞也通过上调CXCL10产生来响应TLR2 / 6激动剂+IFNγ。 本文还公开了这些化合物可用于诱导其他类型的癌症中的CLXL10。 总的来说,这些数据鉴定了TLR2 / 6激动剂+IFNγ的新协同作用,用于直接从黑素瘤细胞诱导CXCL10的产生,提高这些药物的肿瘤内给药可以改善黑素瘤中的免疫特征并且与其他免疫疗法组合具有价值的可能性,通过 支持T细胞迁移到黑素瘤转移。
