Human cytomegalovirus induces an atypical activation of Akt to stimulate the survival of short-lived monocytes.

0 views | Apr 24 2017

Cojohari O et al indicated that HCMV hijacks the upstream Akt signaling network to induce a nontraditional activation of Akt and subsequently a prosurvival decision at the 48-h cell fate checkpoint, a vital step for HCMV's dissemination and persistence strategy. [Read the Full Post]
