生物活性

MEDI-3622 is a human monoclonal antibody against ADAM17. MEDI-3622 blocks the ADAM17-mediated shedding of CD16A and CD62L on NK cells, and binds with high specificity to a surface loop unique to the metalloprotease catalytic domain of ADAM17. MEDI-3622 enhances IFNγ production by NK cells when they bind to antibody-coated tumor cells. MEDI-3622 can be used in the research of ovarian cancer, Burkitt lymphoma, head and neck cancer, and colorectal cancer[1].

体外研究
(In Vitro)

MEDI-3622 可特异性识别人外周血白细胞上的 ADAM17,包括 CD56bright CD3 和 CD56dim CD3 两种人 NK 细胞亚群[1]
MEDI-3622 (1 µg/mL; 2 h) 可阻断由 Trastuzumab (HY-P9907) 结合的 SKOV-3 卵巢癌细胞激活的富集人外周血 NK 细胞中 ADAM17 介导的 CD16A 和 CD62L 的脱落,且不会抑制 NK 细胞的激活 (CD107a 上调)[1]
MEDI-3622 (1 µg/mL; 4 h) 可显著增强经 Trastuzumab 结合的 SKOV-3 或 MA-148 卵巢癌细胞、Rituximab (HY-P9913) 结合的 Raji 伯基特淋巴瘤细胞刺激后的富集人外周血 NK 细胞的 IFNγ 分泌,且在所有测试的效应细胞:靶细胞比例 (10:1 至 1:10) 下均有此作用,但对颗粒酶 A 或颗粒酶 B 的分泌无影响[1]
MEDI-3622 (1 µg/mL; 4 h) 对经 Trastuzumab 结合的 SKOV-3 卵巢癌细胞刺激的富集人外周血 NK 细胞分泌 IFNγ 的增强作用依赖于 CD16A 活性[1]
MEDI-3622 (1 µg/mL; 4 h) 可增强经 Trastuzumab 结合的 SKOV-3 卵巢癌细胞刺激的、表达野生型 CD16A (而非不可切割型 CD16A) 的人 NK 细胞系 NK92 的 IFNγ 分泌,表明该效应是通过阻断 CD16A 的脱落介导的[1]

ELISA Assay[1]

Cell Line: recombinant CD16A-expressing NK92 human NK cell line (wildtype CD16A and non-cleavable CD16A variants)
Concentration: 1 µg/mL
Incubation Time: 4 h
Result: Significantly enhanced IFNγ secretion by NK92 cells expressing wildtype CD16A exposed to trastuzumab-bound SKOV-3 cells.
Had no effect on IFNγ secretion by NK92 cells expressing non-cleavable CD16A (ncCD16A) exposed to trastuzumab-bound SKOV-3 cells.
NK92 cells expressing ncCD16A secreted significantly higher levels of IFNγ than NK92 cells expressing wildtype CD16A when exposed to trastuzumab-bound SKOV-3 cells, even without MEDI-3622 treatment.

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.
