The objectives of this study were to observe the effects of immunization with mouse mature adipocytes for the prevention of obesity in rats and to investigate their mechanism of action. Mouse mature adipocytes (3T3-L1) were injected as a vaccine into the abdominal cavity of rats. Control rats were injected with fibroblast cell lines (MRC-5 or NIH/3T3) or with 0.9% saline. Rats were fed a high calorie diet and body weight changes were used to evaluate obesity prevention. Immuno histochemical and immunofluorescence assays were used to investigate the mechanism of action. Results showed that obesity in rats can be prevented by immunization with xenogeneic mature mouse adipocytes. Body weight gain was inhibited in rats in the treatment group but not in the control groups and was statistically significant between the groups over the 19-week observation period. The assays demonstrated the presence of auto antibodies in rat adipocytes. It was concluded that vaccines of xenogeneic adipocytes can effectively prevent obesity in rats.
