Fas和Fas相关死亡结构域(FADD)在不同细胞类型的动态平衡中起着关键作用。Fas和FADD介导的细胞死亡的调控是许多生理功能的关键。刀豆蛋白A(ConA)激活T淋巴细胞可抑制Fas介导的细胞死亡。我们发现,在ConA刺激下游的几个激活信号中,丝裂原活化蛋白(MAP)激酶(MKK)是拮抗Fas诱导的细胞死亡的主要信号通路。MKK1抑制FADD诱导的细胞凋亡,但不抑制caspase-3诱导的细胞凋亡,表明这种拮抗作用发生在Fas启动的凋亡级联反应的早期。我们进一步证明了MKK1的激活导致了FADD的特异性抑制因子FliP的表达。如果阻止FLIP的诱导,MKK1对FADD诱导的细胞死亡的抑制作用被取消,表明FLIP介导了MKK1对FADD介导的细胞凋亡的抑制。我们的结果说明了一个普遍的机制,通过激活MAPK来减弱正常细胞和转化细胞中由死亡受体启动的凋亡信号。
Fas and Fas-associated death domain (FADD) play a critical role in the homeostasis of different cell types. The regulation of Fas and FADD-mediated cell death is pivotal to many physiological functions. The activation of T lymphocytes by concanavalin A (Con A) inhibited Fas-mediated cell death. We identified that among the several activation signals downstream of Con A stimulation, mitogen-activated protein (MAP) kinase kinase (MKK) was the major kinase pathway that antagonized Fas-triggered cell death. MKK1 suppressed FADD- but not caspase-3– induced apoptosis, indicating that antagonism occurred early along the Fas-initiated apoptotic cascade. We further demonstrated that activation of MKK1 led to expression of FLIP, a specific inhibitor of FADD. MKK1 inhibition of FADD-induced cell death was abrogated if induction of FLIP was prevented, indicating that FLIP mediates MKK1 suppression of FADD-mediated apoptosis. Our results illustrate a general mechanism by which activation of MAP kinase attenuates apoptotic signals initiated by death receptors in normal and transformed cells.
