生物活性

Avelumab (Anti-Human PD-L1) a fully human IgG1 anti-PD-L1 monoclonal antibody (mAb) with potential antibody-dependent cell-mediated cytotoxicity (ADCC). Avelumab enhances ADCC on several cancer cell lines expressing PD-L1. Avelumab can be used for the study of chordoma[1].

体外研究
(In Vitro)

Avelumab 是一种完全人源 IgG1PD-L1 单克隆抗体,具有潜在的抗体依赖性细胞介导的细胞毒作用。与同种型对照相比,Avelumab 使 JHC7 细胞中的 NK 细胞裂解增加 3.1 倍。当用 IFN-γ 处理细胞时,与同种型对照相比,Avelumab 显著增强了以下细胞系中的 NK 细胞裂解:JHC7 (7.56 倍)、UM-Chor1 (7.34 倍)、U-CH2 (2.6 倍)、MUG-Chor1 (8.38 倍)。 Avelumab 可有效提高非癌症干细胞 (CSC) 和 CSC 亚群的抗体依赖性细胞介导细胞毒性 (ADCC),且提高程度相同[1]
结果还表明,与 CEFT 刺激的外周血单核细胞 (PBMC) 中的同种型对照相比,添加 Avelumab 可使抗原特异性多功能 CD8+ T 细胞的频率增加五倍以上[2]

体内研究
(In Vivo)

对单个肿瘤的测量表明,在 Avelumab 给药的小鼠中,肿瘤生长减缓。到肿瘤植入后第 36 天,Avelumab 给药的小鼠的平均肿瘤体积显著减小。Avelumab 给药的小鼠的 MB49 肿瘤生长减少是持久的,并导致存活率显著提高。Avelumab 给药的 10 只患有膀胱肿瘤的小鼠,结果显示 8 只小鼠的肿瘤完全消退,这已通过组织病理学证实。然而,在 CD4 或 CD8 细胞耗尽的小鼠中,Avelumab 在控制膀胱肿瘤负荷方面效果要差得多,在 CD4 T 细胞耗尽的小鼠中,肿瘤突破发生的频率更高[3]

Cell Assay
[1]

To examine the relationship between a cancer stem cell (CSC) subpopulation and antibody-dependent cell-mediated cytotoxicity (ADCC) activity, UM-Chor1 cells are left untreated or treated with 50 ng/mL of IFN-γ for 24 h. Cells are then plated as targets at 50,000 cells/well in 6-well round-bottom culture plates and incubated with 2 μg/mL of Avelumab at room temperature for 30 min. NK cells are added at 2500,000 cells/well at an effector-to-target (E:T) ratio of 50:1. After 4 h, tumor cells are harvested and stained with antibodies for flow cytometry[1].

Animal Administration
[3]

Female C57BL/6 mice are used in this study. Subcutaneous tumor injections are carried out by inoculating C57BL/6 mice with 1×105 MB49 parental cells on the right shaved flank. Tumor growth is measured with calipers and 8 days post-inoculation mice are assigned to treatment groups. Tumor-bearing mice are treated with Avelumab (400 µg per 100 µL) and injected i.p. three times, 3 days apart. Since Avelumab is a human IgG1, three injections have to be compressed within a 7 to 9 day window (i.e., days 9, 12, and 15 post-tumor inoculation) to avoid the onset of neutralizing mouse anti-human Ig[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
