BACKGROUND
Until now, cytokine-induced killer (CIK) cells were assumed to be part of the type I natural killer T (NKT) cell population, but it was not yet investigated if this is correct.
METHODS
For analysis, CIK cells were generated by various culture conditions. Human type I NKT cells express a T cell receptor (TCR) composed of an invariant V alpha 24-J alpha Q chain combined with one of several V beta chains. The V alpha 24 is a reliable marker for the presence of these TCRs.
RESULTS
While comparing cultures stimulated with different substances, we observed the lack of any V alpha 24 on the surface of CIK culture cells.
CONCLUSION
We conclude that CIK cells do not belong to the type I NKT cells.
背景
到目前为止，细胞因子诱导的杀伤（CIK）细胞被认为是I型自然杀伤T（NKT）细胞群体的一部分，但这一观点是否正确尚未得到研究。
方法
为了进行分析，通过各种培养条件生成CIK细胞。人类I型NKT细胞表达一种由不变的Vα24-JαQ链与几种Vβ链之一组合而成的T细胞受体（TCR）。Vα24是这些TCR存在的可靠标志物。
结果
在比较用不同物质刺激的培养物时，我们观察到CIK培养细胞表面缺乏任何Vα24。
结论
我们得出结论，CIK细胞不属于I型NKT细胞。
