Twenty male C57B16/J mice were injected with 50 μl complete Freund's adjuvant (CFA) 1 wk before and 1 wk after induction of diabetes with 45 mg streptozocin (STZ)/kg body weight i.p. over 5 d. CFA administration prevented islet infiltration. Inflammatory cells were not seen within any of the islets observed However, islet B cell destruction still occurred.

Abstract
Twenty male C57B16/J mice were injected with 50 μl complete Freund's adjuvant (CFA) 1 wk before and 1 wk after induction of diabetes with 45 mg streptozocin (STZ)/kg body weight i.p. over 5 d. CFA administration prevented islet infiltration. Inflammatory cells were not seen within any of the islets observed However, islet B cell destruction still occurred. These cells showed evidence of considerable damage, containing swollen mitochondria, contracted nuclei and areas of vacuolation and degranulation. Inflammation is therefore not obligatory for the development of low dose STZ induced diabetes.File in questo prodotto:
