抗小鼠CTLA-4单抗(9D9)在TC1肺癌模型中怎么给药?

Figure 1.Eradication of established tumors by mAb combinations. When s.c. tumors had approximately 25 mm2 surface area, they were injected with indicated single mAbs or mAb combinations for 6 times as shown by arrows. A, survival curves for mice with s.c. SW1 melanoma (left), B16 melanoma (middle), or TC1 lung carcinoma (right). B, tumor growth curves for individual mice with s.c. SW1 melanoma (top), B16 melanoma (middle), or TC1 lung carcinoma (bottom). n = 5 for each group; *, P < 0.05; **, P < 0.01; ***, P < 0.001. Similar results were obtained in at least three independent experiments, summarized in Table 1.

1、用量参考

抗小鼠CTLA-4单克隆抗体(克隆号:9D9)在小鼠肿瘤模型和其他小鼠模型中通常用于体内CTLA-4中和、肿瘤内调节性T细胞耗竭等研究。9D9抗体在设计使用进行体内研究时,确定其给药的最优剂量和方案是非常重要。根据现有文献报道,我们简要总结了抗小鼠CTLA-4单抗(9D9)在TC1肺癌模型 (TC1 lung carcinoma model) 中的给药方案,仅供参考。详情如下表(注意:手机左右滑动查看完整表格):

参数 描述
动物模型 TC1肺癌模型
实验动物 C57BL/6小鼠
给药途径 腹腔注射 (i.p.)
单只剂量 100 μg/次
给药间隔 每3天一次
总给药次数 3次
动物数 5-10 只/组
起始时间 肿瘤接种后第7天
对照建议 相同亚型的同型对照IgG(如小鼠IgG2b)

* 以上为常见方案范围,最佳剂量与频次需结合动物状态与实验目的优化。
