ABSTRACT
Objective To observe the general status and the immunity of DBA/2 mice injected with leukemia vaccine during the immune reconstitution, and to observe the survival rate of these injected mice that were then challenged by L1210 cells. Methods Normal mice and reconstituted lymphopenic mice (RLM; DBA/2 mice rendered lymphopenic with sublethal irradiation and reconstituted with naive splenocytes) were used in the vaccination and challenge experiments with L1210 cells. Results Following vaccination, a significant increase of the IFN-? was detected in the blood of vaccinated RLM compared with that of vaccinated normal mice, as assessed by ELISA. Significantly, greater protection was induced in vaccinated RLM, which led to a stronger protection from death. Conclusion The vaccination of reconstituted lymphopenic hosts could elicit superior anti-tumor immunity compared with normal hosts, highlighting the potential clinical benefit of performing tumor vaccination during immune reconstitution.
