Regulation and induction of anergy in natural killer T (NKT) cells of the liver can inhibit autoimmune and anti-tumor responses by mechanisms that are poorly understood. We investigated the effects of prostaglandin E2 (PGE2), delivered by intestinal, mucus-derived, exosome-like nanoparticles (IDENs), on NKT cells in mice. Here, we demonstrate that IDENs migrate to the liver where they induce NKT cell anergy. These effects were mediated by an IDENs PGE2. Blocking PGE2 synthesis attenuated IDENs inhibition of induction of IFN-γ and IL-4 by α-GalCer stimulated liver NKT cells in a PGE2 EP2/EP4 receptor mediated manner. Pro-inflammatory conditions enhanced the migration of IDENs to the liver where α-GalCer and PGE2 induced NKT anergy in response to subsequent α-GalCer stimulation. These findings demonstrate that IDENs carrying PGE2 can be transferred from the intestine to the liver, where they act as immune modulators, inducing an anergic-like state of NKT cells. These reagents might be developed as therapeutics for autoimmune liver diseases.
