Abstract

Etiological agents of autoimmune processes that have been made nonvirulentby several treatments, i.e., mitomycin C (Mit 0), can be used as a vaccineto protect against disease. In this work we studied the effects of splenocytes from diabetic mice on animals that had been Injected with modified splenocytes (Mit C-treated splenocytes from multiple low-dose streptozotocin [mld-sz] mice) 15 days before. Splenocytes, from mid-sz diabetic donors altered l.p. glucose, tolerance and the first peak of Insulin secretion patternwhen injected Into normal singenelc recipients. These effects can be prevented partially (one, Injection. In a vaccine, form) or completely (two, infections with a 15-day Interval) by a previous, Injection of Mit C-treated mononuclear splenocytes (MS), from mid-sz mice. The fact that control splenocytes previously treated with Mit C were not able to achieve similar results Indicates, that donor, splenocytes have to be diabetic to prevent the disease. On the other hand, Mit C-treated diabetic MS were not effective In preventing the alterations In glucose tolerance and in the pattern of Insulin, secretion: when Injected Into, athymic, mice. This suggests that the preventive effect of Mit C-treated diabetic MS Injection also implies an active, rote of the T cells from the, recipient mice., Mit C-treated diabetic splenocytes are, preferentially trapped by the pancreas and the lymph nodes from recipient mice. Our results show that the Impairment In glucose tolerance and in the Insulin secretion pattern produced by diabetic splenocyte transfer can be prevented by one or two previous injections of Mit C-modified diabetic splenocytes.
