Metbods: The 293 cell was trans fectedwith antisense IRAK-2 oligonucleotide (IRAK-2 ODN) followed by stimulating the cell with IL-1 or tumor necrosis factor (TNF), and then the levels of NF-kappa B activation was analyzed by sandwich enzyme-linked immunosorbent assay (ELISA ). Result: Pre-transfecting with antisense IRAK-2 ODN could remarkably decreasethe levels of NF-kappa B activation stimulated by IL-1 in time- and concentration-dependent manner, it can not attenuate the one stimulated by TNF. Conclusion: The responses of IL-1 and TNF-stimulated NF-kappa B activation to antisense IRAK-2 oligonucleotids were different. IRAK-2 plays a key role in the IL-1 signaling events leading to NF kappa B activation.展开更多
目的探讨嵌合抗原受体(CAR)-T细胞对弥漫大B细胞淋巴瘤(DLBCL)患者Toll样受体4(TLR4)、核因子κB(NF-κB)的影响。方法选择焦作市人民医院收治的14例DLBCL患者作为观察组,给予CAR-T治疗;选择同期行常规化疗的14例DLBCL患者作为对照组,...目的探讨嵌合抗原受体(CAR)-T细胞对弥漫大B细胞淋巴瘤(DLBCL)患者Toll样受体4(TLR4)、核因子κB(NF-κB)的影响。方法选择焦作市人民医院收治的14例DLBCL患者作为观察组,给予CAR-T治疗;选择同期行常规化疗的14例DLBCL患者作为对照组,比较两组临床效果。结果三代细胞各培养时间点细胞体外增殖能力均明显高于二代细胞(P<0.05)。观察组患者治疗后完全缓解(CR)+部分缓解(PR)有效率明显高于对照组(P<0.05)。对照组治疗后3 d及7 d CD19+细胞比例均较治疗前提升(P<0.05);观察组治疗后3 d及7 d CD19+细胞比例均较治疗前显著降低(P<0.05),且显著小于对照组(P<0.05)。观察组治疗后3 d及7 d TLR4与NF-κB水平均较治疗前显著下降(P<0.05),且显著小于对照组治疗后(P<0.05)。结论CAR-T治疗DLBCL短期疗效显著,可有效降低TLR4与NF-κB水平。展开更多
