Cycling SI-Ep immigrants are the precursors of Granzyme Bhigh cells. (A) Flow cytometric analysis of the expression levels of Granzyme B in normal IELs and MLNs (15 mice in 15 independent experiments). (B) Structural analysis of Granzyme B content with ImageStream system (Amnis) in the indicated subsets of CD3+ IELs, as defined in the accompanying dot plot (one experiment [preliminary]). (C) Dot plots correlating CD69 expression and levels of Granzyme B in the indicated CFSE generations of donor γδ or CD8αβ SI-Ep immigrants. Data are representative of seven recipients individually analyzed at days 4–8 after transfer, in seven independent experiments.
