T cell response in DA rats 28 days after MOG immunization. The DA rats were immunized with 20 μg MOG and 28 days later, the spleen and deep cervical lymph nodes were excised and the cells stimulated with a medium, rrNF, and MOG. T cell proliferation was measured by H3 thymidine incorporation and displayed as scintillation (CPM counts per minute). The statistical significance in the T cell response between the medium and rrNF was calculated by using non-parametric Mann-Whitney test in GraphPad Prism 5.0. *p < 0.05. Error bars represent standard error of the mean (SEM)
