实验室在做细胞因子检测时,一般会用Cell activation cocktail(with Brefeldin A)对细胞进行处理,但是我比较困惑其中的PMA/ion会对细胞状态有影响,不能真实反映体内情况。文献中说:PMA/iono is usually a stronger inducer of cytokine expression compared to CD3/CD28 stimulation. While it might be argued that this trigger is not hysiological, it is very well suited to reveal the maximal cytokine expression potential of the T cells rather than their actual cytokine expression e.g. in vivo at the time point of analysis.
