Objective:
To investigate the effect of T-cell vaccination in murine experimental autoimmune hepatitis (EAH).
Methods:
To induce the EAH model, the syngeneic S-100 antigen emulsified in complete Freud's adjuvant was injected intraperitoneally to C57Bl/6 at day 1 and day 7. For T-cell vaccination, splenocytes were removed from animal 2 weeks after induction of EAH and from control animals, and activated in vitro by mitogen stimulation with Concanavalin A (Con A), then inactivated by mitomycin and injected at 5 10(7) cells per animal as T-cell vaccination at 14 and 7 days before first induction of EAH.
Results:
The histological grade and serum ALT level of the mice who received T-cell vaccination were decrease significantly, compared with that of model group (1.44+/-0.88 vs. 2.33+/-0.87, t=2.24, P<0.05; 63.0U/L+/-23.4U/L vs. 115.0U/L1+/-39.6U/L, t=2.37, P<0.01, respectively); there was no significant change in mice who received irrelevant T-cell vaccination.
Conclusion:
T-cell vaccination with T cells from EAH animals, but not with irrelevant T cells, was able to protect animals from EAH.
