新品简介

免疫检查点分子逐渐被认为是肿瘤免疫治疗的新靶标,它通常被肿瘤细胞“劫持”,以束缚免疫系统发挥有效的抗肿瘤反应的能力。免疫检查点阻断(Immune Checkpoint Blockade)是激活抗肿瘤免疫的有希望的方法。细胞毒性T淋巴细胞相关抗原4(CTLA-4)和程序性细胞死亡受体1(PD-1)是目前研究的最透彻的免疫检查点分子,anti-CTLA4和anti-PD1单克隆药物已经在多种恶性肿瘤的临床试验中展现出不错的疗效。

案例展示

OX40 / CD134是肿瘤坏死因子(TNF)受体家族的成员。它是一种有效的共刺激途径的一部分,当被触发时可以在几种临床前癌症模型以及人类中增强T细胞记忆,增殖和抗肿瘤活性,从而克服癌症的一些免疫抑制性质。

OX40 / CD134 is a member of the tumor necrosis factor (TNF) receptor family. It is part of a potent co-stimulatory pathway that when triggered can enhance T-cell memory, proliferation and antitumor activity in several preclinical cancer models as well as in humans thus overcoming some of the immunosuppressive properties of cancer.

OX40-HEK293 cells were stained with FITC-labeled anti-OX40 antibody and analyzed by FACS.

Y-axis shows the cell count. X-axis shows the intensity of FITC fluorescence.
