Multiple low doses of streptozotocin (5 x 40 mg/kg) given to susceptible male C57BL6 mice induced delayed and sustained hyperglycemia accompanied by body weight loss, mononuclear cell infiltration in the islet, and apoptosis of beta cells. Shorter regimes (4 x 40 mg/kg) did not have such effect. Administration of IL-23 at a dose of 400 ng/mL for 10 consecutive days concomitantly with this subdiabetogenic regimen of STZ, however, induced significant hyperglycemia, weight loss, and mononuclear cellular infiltration. The same regimen of IL-27 induced milder effect on glycemia and no weight loss inspite of a massive peri-islet and intra-islet infiltration of mononuclear cells. The molecular mechanisms underlying the actions of these cytokines on diabetogenesis is under study.
