description

In a recent issue of Nature, Sanmarco et al. reveal a novel mechanism by which astrocytes maintain an anti-inflammatory state in the central nervous system (CNS). IFNγ released by gut-licensed meningeal NK cells was found to induce TRAIL expression on astrocytes, causing effector T cell apoptosis.
