Hyperinsulinemia induced by canine distemper virus infection of mice and its correlation with the appearance of obesity.
1. Weanling Swiss mice surviving an acute infection with canine distemper virus were persistently infected. Among these mice, up to 30% had hyperinsulinemia and this was followed by an obesity syndrome. 2. Analysis of the lipid composition of various organs revealed that compared to control animals, the obese had an accumulation of triglycerides in both liver and adipose tissue. 3. Studies on the lipid metabolism using a number of radioactive lipid precursors showed a specific accumulation of the triglycerides of the obese animals. 4. A decrease of lipogenesis was observed in white adipose tissue of obese mice. Glycogenesis and serum glucose levels were unaffected during obesity. 5. The model of canine distemper virus-induced obesity is compared with other experimental models.
