Figure 3. Glycopeptide specific RFT CD4 T cells proliferate to endogenous stimulation in the periphery of MUC1-Tg mice.
3-5×106 CFSE-labeled T cells were transferred (i.v.) to recipient mice (WT, n=6; MUC1-Tg, n=5). 5-7 days following adoptive transfer, recipient mice splenocytes were analyzed by flow cytometry for the presence of RFT CD4 T cells (CD3+CD4+CD45.1+). T cell proliferation is shown as A) percent of RFT CD4 T cells with decreased CFSE fluorescence and B) CFSE mean fluorescent intensity (MFI) of proliferating cells, calculated using the gating strategy in panel A. C) Percent of RFT CD4 T cells with respect to the recipient mouse CD4 T cell population. Mean values are shown (—). Data is representative of two independent experiments. The p values were calculated using an unpaired t test.
