We conclude that IA-2beta is involved in insulin secretion, but despite its importance as a major autoantigen in human type 1 diabetes, it is not required for the development of diabetes in NOD mice.
We found that the CD19+IgM+ cell is the primary subpopulation of B cells that delayed transfer of diabetes mediated by diabetogenic T cells from NOD mice (P = 0.002).
In the resulting 3A9 TCR:iHEL NOD.H2(k)-Chr12 mice, we observed a significant decrease in diabetes incidence as well as a decrease in both the quantity and affinity of HEL-specific IgG autoantibodies relative to 3A9 TCR:iHEL NOD.H2(k) mice.
Despite the well known role of nucleotide oligomerization domain (NOD) receptor proteins in innate immunity, their association with diabetes is less explored.
This was demonstrated by greater ability to cause recurrent diabetes in NOD-RIP-CD86 diabetic mice transplanted with 6-wk-old NOD islets and adoptively transferred diabetes from diabetic NOD-RIP-CD86 mice to NOD.scid mice.
Because exogenous IL-4 and IL-10 exert antidiabetogenic effect in NOD mice and early blockade of endogenous tumor necrosis factor-alpha prevents NOD mouse diabetes, these phenomena may be causally related to the antidiabetogenic effect of HGG-pulsed DC treatment.
We conclude that treatment of NOD mice with an antibody against CSF-1 receptor reduced diabetes incidence and led to the development of a regulatory pathway that controlled autoimmune progression.
By using the recombinant PLAD.Fc protein to block TNFR1 assembly, we demonstrated that PLAD.Fc treatment significantly reduced the TNFR1-driving proinflammatory cytokines and protected NOD mice from diabetes.
A single administration of rAd-GLP-1 via the tail vein into streptozotocin (STZ)-induced diabetic non-obese diabetic/severe combined immunodeficient (NOD/SCID) mice resulted in remission of diabetes within 10 days; normoglycemia remained until the experiment was terminated.
Here, we used direct non-invasive confocal imaging of islets transplanted in the anterior chamber of the eye (ACE) to investigate the anti-islet autoimmunity in NOD mice before, during and after diabetes onset.
Here we show that proinsulin B24-C36 peptide binds to I-A(g7), the MHC class II molecule of the NOD mouse, and, after intranasal administration, induces regulatory CD4(+) T cells that, in the absence of CD8(+) T cells, block the adoptive transfer of diabetes.
Thioredoxin-interacting protein (TXNIP), a regulator of cellular oxidative stress, has been associated with activation of NOD-like receptor 3 (NLRP3) inflammasome, inflammation and lipid metabolism, suggesting it has a role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) in diabetes.
To test the role of gut microbiota on diabetes development in this model system, we treated the <i>A22Cα<sup>-/-</sup>PI2<sup>-/-</sup></i> NOD mice with enrofloxacin, a broad-spectrum antibiotic.
