(I-J) Fold change in mRNA expression for the indicated cytokines in ILC3s sort-purified from spleen (I) or SI-LP (J) 6 h after intravenous (I) or oral (J) αGalcer administration. Gene expression was measured by qPCR and normalized to GAPDH and to the expression levels in ILC3s sort-purified from PBS-injected mice (n=3). *p<0.05, **p<0.01 two-tailed unpaired t-test.
