Figure 4.
Effect of mast cell mediators on Jurkat cell activation. Jurkat cells were also incubated with (a) supernatant fluid collected from mast cells treated with MBP (10 μM) and IL-2 release was measured in the supernatant fluid by ELISA (n=3); (b) with TNF-neutralizing antibody (n=3) for 1 h before activation with anti-CD3/anti-CD28 and the addition of mast cells with or without MBP. After 48 h, the supernatant fluid was collected and assayed for IL-2 level by ELISA. (a) *P<0.05 compared with condition 3; (b) @,*P<0.05, @=compared with condition 1, *=compared with condition 3.
