Fig. 4. The effect of BSE on the proliferation of T cells and B cells.Cell proliferation was measured by WST-1 assay. The statistical analysis of the data was carried out by use of a t-test. *p < 0.05, **p < 0.01 and ***p < 0.001 compared to control. (A) Molt-4 cells were pretreated with BSE and Con A (5 μg/mL) for 24 h. (B) Raji cells were pretreated with BSE and LPS (1 μg/mL) for 24 h. N.S.; not significant (each experiment, n = 3).
