[The effect of IL-2 and IL-3 gene therapy in mice on immunological recovery receiving high dose chemotherapy].
OBJECTIVE
To investigate the effect of Ad-IL-2 and Ad-IL-3 on immunological recovery.


METHODS
The Ad-IL-2 and/or Ad-IL-3 were i.p. injected into C57BL/6 mice having received high dose cyclophosphamide (200 mg/kg) 24 hours before. The number and cytotoxicity, Ia antigen expression of peritoneal macrophages, the proliferation and NK cell activity of splenic cells were observed.


RESULTS
After i.p. injection with Ad-IL-3, the number, cytotoxicity and Ia antigen expression of peritoneal macrophagee were increased. After i.p. injection with Ad-IL-2, the proliferation and NK cell activity of splenic cells were significantly augmented. As i.p. injection with Ad-IL-2 and Ad-IL-3 simultaneously, both the peritoneal macrophages and splenic cells were activated.


CONCLUSIONS
Intraperitoneal injection of Ad-IL-2 and Ad-IL-3 can promote immune recovery after high dose chemotherapy.
