一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
CCG 2046是TNF-α的抑制剂,HTRF测定和ELISA测定中,IC50值分别为2.32 μM 和0.66 μM [1]。CCG 2046也是RGS4的抑制剂。
肿瘤坏死因子(TNF)家族有三个成员:TNF-α、TNF-β和LT-β,TNF-β也称为淋巴细胞毒素α,LT-α。肿瘤坏死因子α(TNF-α)是一种细胞分泌因子。它在免疫疾病和炎性疾病中起重要作用。TNF-α也参与抑制病毒复制以及程序性细胞死亡。在细胞水平上,TNF-α可以调节多个信号通路,如NF-κB的活化和细胞凋亡[1]。
LPS和TNF-α均可以下调RGS4 [2]。CCG 2046降低RGS4-Gα0相互作用信号,IC50值为4.3 ± 0.2 μM[3]。Infliximab也是TNF-α的抑制剂[4]。使用兔抗人TNF-α多克隆抗体刺激mTNF 6小时后,IL-10的 mRNA含量增加2.6倍。使用WT mTNF转染Jurkat细胞,经过10 μg/mL的infliximab培养24小时,IL-10的生成增加2.7倍,具有统计学意义。这些结果通过cDNA阵列分析表示[5]。
Infliximab输注1小时后,在一些病人血清中TNF-α蛋白的浓度显著降低。Infliximab首次剂量24小时和48小时之后,患者CCL2浓度显著下降[4]。TNF-α促进肿瘤细胞CCL2的表达[6]。
