C57BL/KsJ (BKs) male mice were more sensitive to diabetes induction by administration of multiple low-doses of streptozotocin (Sz) than were C57BL/6J (B6) male mice. Analysis of islet size and insulin content of the two parental strains did not indicate that differences in drug sensitivity could be attributed to an effect of genetic background on islet size or insulin content. 50 BKs islets implanted into the spleens of BKs male mice made diabetic by Sz were eliminated within 12 days posttransplantation, whereas an equal number of B6 islets implanted into the spleens of diabetic B6 recipients were retained, even though the numbers of islets implanted were insufficient to effect remission from hyperglycemia. In contrast to the rapid loss of islets implanted into spleens of hyperglycemic BKs recipients, BKs islets implanted into spleens of normoglycemic recipients were not eliminated, thus suggesting that the basis for the differential survival between the B6 and BKs strains reflected their ability to survive hyperglycemic stress rather than a differential ability to replicate. Since BKs beta cells have been shown to respond to hyperglycemia by expression of an endogenous retroviral gene that cannot be expressed by B6 beta cells, the possibility that this differential survival represents a strain difference in autoreactivity against islet cells is raised.
