T cell-related immune responses elicited in JOL1454-immunized mice. Representative flow cytometry scatter dot plots for CD3+ and CD3 + CD4+ splenic T cell populations of non-immunized mice (a) and the immunized mice (b). The subpopulations are presented as a percentage of gated cells. CD3+ and CD3 + CD4+ T lymphocyte populations in immunized and non-immunized mice (c) and stimulation index (SI) values of splenic T cells of the purified Stx2eB protein-immunized group, determined by MTT assay (d). The values are expressed as the mean ± s.d. of five individual values. *, P < 0.05
