Figure 3 Flow cytometry (FCM) analysis of lamina propria (LP) cells in the large intestine from dextran sulphate sodium (DSS) treated interleukin (IL)‐15 knockout (KO) mice. LP cells in the large intestine of DSS treated IL‐15 KO mice, DSS treated wild‐type (WT) mice, and IL‐15 KO mice and WT mice not treated with DSS were stained with various monoclonal antibodies (CD3, NK1.1, CD4, or CD8). The results of FCM are presented as typical profiles after an analysis gate had been set on lymphocytes using forward and side scatter.
