---|---|---|
WT | nul | |
DNP-KLH (day 14) | 5.14 ± 1.45 | 0.34 ± 0.08** |
DNP-KLH (day 28) | 9.13 ± 1.94 | 0.61 ± 0.08*** |
TNP-LPS (day 14) | 6.72 ± 0.70 | 0.60 ± 0.08*** |
DNP-Ficoll (day 14) | 8.18 ± 0.27 | 0.74 ± 0.07*** |
mPGES-1 WT and null mice were injected i.p. with T-cell dependent (TD) antigen DNP-KLH in CFA, T-cell independent type1 (TI-1) antigen TNP-LPS or T-cell independent type2 (TI-2) antigen DNP-Ficoll on day 0. Spleen was isolated at the indicated time point and the levels of PGE2 were determined by ELISA. Data are expressed as the mean + SEM (n=4–11).
indicate statistical significance at P<0.01 and P<0.001, versus WT mice.
