ILC2s navigate tissue redistribution during infection using stage-specific S1P receptors

iILC2s were sort-purified from the gut, mesenteric lymph node, and the lung of C57BL/6 mice (iILC2: Lin- CD45+ KLRG1+ ST2-) on day 4 after IL-25 injection. ILC2 were sort-purified from the gut of C57BL/6 mice ((ILC2: Lin- CD45+ KLRG1+ ST2+).(Gut ILC2: n= 2 and Gut iILC2 n= 2, and mesLN iILC2 n= 2, and Iung iILC2 n= 2).
