Objective:

To systematically investigate the dynamic tissue distribution and tumor-targeting characteristics of memory T cells in non-tumor-bearing and tumor-bearing NCG mouse models using validated qPCR and in vivo imaging techniques.

Methods:

A total of 144 NCG mice were randomly divided into non-tumor-bearing control, tumor-bearing control, non-tumor-bearing treatment, and tumor-bearing treatment groups. The treatment groups received a single intravenous injection of 1×107 memory T cells per mouse, while the control groups received vehicle only. In vivo imaging was performed on days 1, 3, 7, 14, 21, and 28 post-administration. Tissues and body fluids were collected at the same time points, and the genomic distribution of memory T cells was quantified by qPCR.

Results:

In non-tumor-bearing mice, memory T cells were initially (day 1~3) distributed mainly in highly perfused organs such as the lung, spleen, and liver, followed by a rapid decline and near clearance by day 14. In tumor-bearing mice, the early distribution pattern resembled that in non-tumor-bearing animals; however, starting from day 14 onward, significant tumor enrichment was observed and persisted until day 28, accompanied by a concurrent decrease in cell concentrations in non-target tissues.

Conclusion:

Memory T cells demonstrate a trend of rapid clearance in the absence of antigenic stimulation, whereas in the presence of tumor, they exhibit antigen-driven tumor homing and long-term persistence capabilities.

目的:

利用经方法学验证的qPCR技术及活体成像技术,系统研究记忆T细胞在非移植瘤与移植瘤NCG小鼠模型中的动态组织分布及其肿瘤靶向特性。

方法:

取144只NCG小鼠,随机分为移植瘤与非移植瘤阴性对照组及记忆T细胞注射液组,给药组给予记忆T细胞1×107 cells·只-1,阴性对照组不给药。于给药后1、3、7、14、21及28 d进行活体成像,并于各时间点采集各组织或体液,通过qPCR定量分析记忆T细胞基因组分布。

结果:

非移植瘤小鼠中,记忆T细胞早期(1~3 d)主要分布于肺脏、脾脏、肝脏等高血流灌注器官,随后逐渐减少,d 14基本清除。移植瘤组早期分布与非移植瘤组相似,d 14后出现的显著肿瘤富集持续至d 28,非靶组织细胞浓度同步下降。

结论:

记忆T细胞在无抗原刺激下呈快速清除趋势,而在肿瘤存在时则表现出抗原驱动性肿瘤归巢与长期驻留能力。

目的:

利用经方法学验证的qPCR技术及活体成像技术,系统研究记忆T细胞在非移植瘤与移植瘤NCG小鼠模型中的动态组织分布及其肿瘤靶向特性。

方法:

取144只NCG小鼠,随机分为移植瘤与非移植瘤阴性对照组及记忆T细胞注射液组,给药组给予记忆T细胞1×107 cells·只-1,阴性对照组不给药。于给药后1、3、7、14、21及28 d进行活体成像,并于各时间点采集各组织或体液,通过qPCR定量分析记忆T细胞基因组分布。

结果:

非移植瘤小鼠中,记忆T细胞早期(1~3 d)主要分布于肺脏、脾脏、肝脏等高血流灌注器官,随后逐渐减少,d 14基本清除。移植瘤组早期分布与非移植瘤组相似,d 14后出现的显著肿瘤富集持续至d 28,非靶组织细胞浓度同步下降。

结论:

记忆T细胞在无抗原刺激下呈快速清除趋势,而在肿瘤存在时则表现出抗原驱动性肿瘤归巢与长期驻留能力。

Objective:

To systematically investigate the dynamic tissue distribution and tumor-targeting characteristics of memory T cells in non-tumor-bearing and tumor-bearing NCG mouse models using validated qPCR and in vivo imaging techniques.

Methods:

A total of 144 NCG mice were randomly divided into non-tumor-bearing control, tumor-bearing control, non-tumor-bearing treatment, and tumor-bearing treatment groups. The treatment groups received a single intravenous injection of 1×107 memory T cells per mouse, while the control groups received vehicle only. In vivo imaging was performed on days 1, 3, 7, 14, 21, and 28 post-administration. Tissues and body fluids were collected at the same time points, and the genomic distribution of memory T cells was quantified by qPCR.

Results:

In non-tumor-bearing mice, memory T cells were initially (day 1~3) distributed mainly in highly perfused organs such as the lung, spleen, and liver, followed by a rapid decline and near clearance by day 14. In tumor-bearing mice, the early distribution pattern resembled that in non-tumor-bearing animals; however, starting from day 14 onward, significant tumor enrichment was observed and persisted until day 28, accompanied by a concurrent decrease in cell concentrations in non-target tissues.

Conclusion:

Memory T cells demonstrate a trend of rapid clearance in the absence of antigenic stimulation, whereas in the presence of tumor, they exhibit antigen-driven tumor homing and long-term persistence capabilities.
