Figure 1 Type I IFN Signaling Protects Activated T Cells from NK-Cell-Mediated Death Type I IFN signals to antigen-activated T cells reduce the expression of NK cell activatory ligands and elevates the levels of inhibitory ligands, rendering the responding T cell resistant to NK cell attack. Without type I IFN signals, activated T cells can be targeted by perforin-dependent NK cell killing. Immunity 2014 40, 861-862DOI: (10.1016/j.immuni.2014.05.009) Copyright © 2014 Elsevier Inc.
