我们在这里提出一个标准免疫技术 (CFSE 染色的应用), 旨在快速监测佐剂介导的细胞毒性 T 淋巴细胞 (CTL) 生成在体内.这种对 CTL 容量的快速估计有助于开发预防性疫苗, 防止细胞内病原体和治疗性癌症疫苗的发展。
本实验的总体目标是通过监测免疫受体动物引流淋巴结和脾脏中过继转移的 CFSE 染色的 OT1 CD8 阳性 T 细胞增殖,确定感兴趣的佐剂产生细胞毒性 T 淋巴细胞的能力。这种方法可以帮助回答疫苗学领域的关键问题,例如佐剂产生细胞毒性反应的效力。这种技术的主要优点是,您不仅可以确定佐剂的 CTL 容量,还可以确定这是局部的还是全身的,并且您只能在四天内完成。
演示该程序的将是我们实验室的技术人员 Elena Reinhard。要从 OT1 小鼠中分离大腿 1.1 阳性 CD8 阳性 T 细胞,首先根据标准方案收获脾脏和腹股沟、腋窝和颈部淋巴结,将所有器官放入 60 毫米培养皿中的 100 微米孔网过滤器中,每只小鼠含有 3 至 5 毫升冰上完全培养基,当收集它们时。不要在大的 OT1 脾脏或淋巴结中收获,因为来自这些淋巴组织的 T 细胞可能是白血病的,即使没有刺激也会增殖,从而混淆检测结果。
