Potent and selective stimulation of memory-phenotype CD8+ T cells in vivo by IL-15.

abstract：:The peptidoglycan sensor Nod2 and the autophagy protein ATG16L1 have been linked to Crohn's disease (CD). Although Nod2 and the related sensor, Nod1, direct ATG16L1 to initiate anti-bacterial autophagy, whether ATG16L1 affects Nod-driven inflammation has not been examined. Here, we uncover an unanticipated autophagy-i...
