抗小鼠CTLA-4抗体(9D9)在EMT6乳腺癌模型中怎么给药?

Fig 1 CD4+ T cells play a crucial role in immune checkpoint inhibitor treatment against tumor growth. Tumor growth of (A) MB49 (n = 7), EMT-6 (n = 5), CT26WT (n = 7) and Hepa1-6 (n = 5) tumors with or without anti-CTLA-4 Ab treatment (n = 7). The average tumor volume is shown as the mean ± standard error of the mean (SEM). * P < 0.05, ** P < 0.01, *** P < 0.001 by Mann-Whitney test at the endpoint. (B, C) Tumor growth of Hepa1-6 or Hepa1-6#12 tumors with or without anti-CTLA-4 Ab co-administered with a depleting Ab against CD4+ or CD8+ T cells. These depletion Abs were injected via intraperitoneal administration starting 2 days prior to tumor cell injection and continued weekly. The average tumor volume is shown as the mean ± SEM (n = 7–8). * P < 0.05, ** P < 0.01, *** P < 0.001 by one-way ANOVA followed by Dunnett’s test at the endpoint.

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EMT6乳腺癌模型 (EMT6 mammary 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 EMT6乳腺癌模型
实验动物 BALB/c雌性小鼠(6-8周龄)
给药途径 腹腔注射 (i.p.)
单只剂量 200 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。
