HIV Vpr induces a cell-cycle arrest at the G2-to-M transition through a poorly understood mechanism. In a recent issue of Cell, Laguette et al. (2014) demonstrate that untimely activation of the structure-specific endonuclease regulator SLX4 complex by Vpr promotes G2/M arrest and escape from innate immune sensing.
HIV Vpr 通过一种尚未完全阐明的机制诱导细胞周期在 G2 到 M 期过渡时停滞。在最近一期的《Cell》杂志上,Laguette 等人(2014)证明,Vpr 会过早激活结构特异性内切酶调控因子 SLX4 复合物,从而促进 G2/M 期停滞并逃避先天免疫感应。
