Abstract

Studies of animals with spontaneous autoimmune diabetes have revealed that autoreactive T cells that mediate islet beta-cell destruction belong to the Th1 subset (producing IL-2 and IFN-gamma), whereas regulatory T cells are Th2 type (producing IL-4 and IL-10). Here, we evaluate the effect of combined delivery of plasmid DNA encoding IL-4 and IL-10 using a degradable, cationic polymeric carrier, poly[gamma-(4-aminobutyl)-L-glycolic acid] (PAGA), in nonobese diabetic (NOD) mice. In the liver of NOD mice, we detected mouse Il4 and Il10 mRNA 5 days after intravenous injection of both PAGA-Il4 and PAGA-Il10 plasmid complexes. We found that 6 weeks after injection, 75% of observed islets were intact compared with less than 3% in the control group. Furthermore, in the treatment group, only 5% of the islets were severely infiltrated by the lymphocytes compared with over 30% in the control group. We measured glucose levels weekly up to the age of 32 weeks, revealing that co-injection of PAGA-Il4 and PAGA-Il10 plasmids prevented the development of diabetes in 75% of the treated animals. Thus, combined administration of mouse Il4 and Il10 plasmids prevents the development of autoimmune diabetes in NOD mice.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • DNA encoding IL-10 and IL-4 encapsulated in polymeric nanoparticles delivered into white blood cells inhibits T cell response against residual native islet cells in prediabetic animal model, inhibiting diabetes development in 75% of animals.

    “DNA encoding interleukin (IL)-10 and IL-4 encapsulated in polymeric nanoparticles has been delivered into white blood cells to inhibit the T cell response against residual native islet cells in a prediabetic animal model. It was found to be very helpful in diabetic management because it inhibited diabetes development in 75% of the animals.94”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
