| I. Background | |
| 活化 B 細(xì)胞的核因子 κ 輕鏈增強(qiáng)子( NF-κB ) 是一個(gè)轉(zhuǎn)錄因子蛋白復(fù)合物家族，可控制 DNA 轉(zhuǎn)錄、細(xì)胞因子產(chǎn)生和細(xì)胞存活。NF-κB 存在于幾乎所有動(dòng)物細(xì)胞類型中，并參與細(xì) 胞對(duì)壓力、細(xì)胞因子、自由基、重金屬、紫外線照射、氧化 LDL 以及細(xì)菌或病毒抗原等刺 激的反應(yīng)。 NF-κB 的激活涉及兩條主要信號(hào)通路，即經(jīng)典通路和非經(jīng)典（或替代）通路，盡管它 們的信號(hào)機(jī)制不同，但都對(duì)調(diào)節(jié)免疫和炎癥反應(yīng)十分重要。經(jīng)典 NF-κB 激活的主要機(jī)制是 通過多亞基 IκB 激酶 (IKK) 復(fù)合物對(duì) IκBα 的位點(diǎn)特異性磷酸化引發(fā)的誘導(dǎo)性降解。與經(jīng)典 NF-κB 通路相反，非經(jīng)典 NF-κB 通路選擇性地對(duì)一組特定的刺激作出反應(yīng)，包括 TNFR 超 家族成員子集的配體，例如 LTβR、BAFFR、CD40 和 RANK。 | |

NFκB-Luc Jurkat 報(bào)告基因細(xì)胞是由 NFκB 調(diào)控并表達(dá) Luc 熒光素酶報(bào) 告基因的 Jurkat細(xì)胞。PMA 是 DAG（二酯酰甘油）的類似物，可自由的通過細(xì)胞膜，直接 作用于細(xì)胞活化信號(hào)轉(zhuǎn)導(dǎo)通路上的 PKC，原理見下圖所示。 Figure 1：NFκB-Luc Jurkat 細(xì)胞模型原理圖 | |
