Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is one of the several members of the necrosis factor (TNF) gene superfamily that induce apoptosis through engagement of death receptors (DRs).

• 肿瘤坏死因子相关的凋亡诱导配体(TNF-related apoptosis inducing ligand, TRAIL)是肿瘤坏死因子(tumor necrosis factor, TNF)基因超家族众多成员之一,能通过死亡受体的参与而诱导细胞凋亡。
