I wanted to start this thread to share studies by Dr. Denise Faustman (http://www.faustmanlab.com), as well as studies that are relevant to her method. For those who don't know, Dr. Faustman cured end-stage non-obese diabetic (NOD) mice by injecting them with a compound that stopped the autoimmune attack, leading to the restoration of insulin production (articles below).
I'd like this to be a running thread where people can post other studies.
Possible topics/search terms:
BCG vaccination and type 1 diabetes
CD8+ T-cells and autoimmunity
NOD mice
TNF-alpha
It would be great if anyone who has access to scientific journals could post the full articles.
I'll start.
I have this article in PDF

Abstract: Nonobese diabetic (NOD) mice are a model for type 1 diabetes in humans. Treatment of NOD mice with end-stage disease by injection of donor splenocytes and complete Freund's adjuvant eliminates autoimmunity and permanently restores normoglycemia. The return of endogenous insulin secretion is accompanied by the reappearance of pancreatic ß cells. We now show that live donor male or labeled splenocytes administered to diabetic NOD females contain cells that rapidly differentiate into islet and ductal epithelial cells within the pancreas. Treatment with irradiated splenocytes is also followed by islet regeneration, but at a slower rate. The islets generated in both instances are persistent, functional, and apparent in all NOD hosts with permanent disease reversal.

Abstract: In the last decades of the 20th century, the incidence rate of type 1 diabetes increased in affluent countries. The pattern of occurrence of this autoimmune disease over time could provide helpful information to discriminate between alternative aetiologic hypotheses. In addition to genetic disposition, the incidence of type 1 diabetes seems to be conditioned by environmental factors and lifestyle. One theory proposes that the increase in the prevalence of autoimmune diseases is a result of the decrease in the incidence of childhood infections. To investigate the relationship between the incidence of type 1 diabetes and the decline of infectious diseases, we calculated the correlation between the occurrence of type 1 diabetes and tuberculosis in several European and non-European countries. The results of our analysis demonstrate an inverse correlation between the occurrences of type 1 diabetes and tuberculosis. A possible interpretation of this negative association is that a high socio-economic status and a westernised way of life imply a reduced or delayed exposure to infectious agents and so a reduced or delayed “pressure” on the immune system, which is free to mount inappropriate responses against self-antigens, as happens in type 1 diabetes.

Abstract: We have previously shown that immunotherapy with complete Freund's adjuvant (CFA) or BCG is highly effective in the prevention of spontaneous insulin-dependent diabetes mellitus (IDDM) and in circumventing the rejection of syngeneic islet grafts in diabetic NOD mice. This protection is reversed by treatment with cyclophosphamide (Cy). The present study was undertaken to determine the effect of BCG vaccination on the progression of Cy-accelerated diabetes in NOD mice and to understand the mechanism of BCG immunotherapy. The time course of Cy and BCG administration showed that the progression of Cy-induced diabetes can only be blocked when BCG vaccination is given within 3 days of Cy administration. Mice given BCG 3 days before (−3 days) or 7 days after Cy treatment were not protected. BCG immunization 1 day after Cy treatment almost completely prevented insulitis in the islets of Cy-treated mice. Cy treatment reduced the endogenous production of anti-GAD67 antibody, whereas BCG vaccination 1 day after Cy treatment restored the production of anti-GAD67 antibody of IgG1 isotype. The comprehensive effect of BCG vaccination on cytokine production in Cy-treated mice was to increase IL-4 production and change the IL-4/IFN-γ ratio in both serum and supernatant of spleen cell cultures. We found that BCG-induced protection was associated with increased splenic CD4+CD45 RBhighT cells. Taken together, our results indicate that BCG treatment counteracts the effect of Cy on autoimmune process in IDDM. However, BCG immunotherapy has a narrow window of up to 3 days after Cy treatment to block the progression of Cy-induced diabetes and to allow for the induction of regulatory cells which may effectively downregulate the diabetogenic cells. In summary, our results suggest that BCG vaccination prevents IDDM if given in the prediabetic state. After the induction of diabetes, disease progression can only be prevented within a narrow window of opportunity by this treatment.
