1 3040496 We have recently shown that interferon-gamma (IFN-gamma) markedly upregulates the expression of the class I major histocompatibility proteins on pancreatic beta cells and have therefore postulated that interferon-gamma may enhance cytotoxic lymphocyte-mediated beta cell damage in insulin-dependent diabetes mellitus.

6 2518361 These findings suggest that cytokine products of T lymphocytes (IFN-gamma) and macrophage/monocytic cells (IL-1, TNF) infiltrating pancreatic islets in "autoimmune" diabetes may interact synergistically to produce functional inhibition or lethal cytocidal effects on islet beta-cells, possibly accounting for reversible and irreversible stages of insulin-dependent diabetes.

10 8383325 Higher concentrations (IL-1 beta at 75 units/ml, 3.5 nM TNF-alpha, and IFN-gamma at 750 units/ml) inhibit insulin secretion from human islets, and the inhibitory effect is prevented by NG-monomethyl-L-arginine.
11 7514190 An exposure of 144 h to IL-1 beta plus IFN-gamma plus TNF-alpha increased NO production and decreased both glucose-induced insulin release and insulin content.
12 7756973 Glucose-induced insulin secretion is inhibited by the cytokines interleukin-1 beta (IL-1 beta), interleukin-6 and tumour necrosis factor alpha (TNF) when combined with IL-1 beta in cultured rat islets, by IL-1 beta, TNF and interferon gamma in mouse islets, and by combined treatment of IL-1 beta, TNF and interferon gamma in human islets.
13 8781713 Since glutamic acid decarboxylase-65 (GAD-65) is a target autoantigen in IDDM, we investigated whether the cytokines IL-1 beta, TNF alpha IFN gamma altered islet cell expression of GAD-65 and whether the effect of cytokines on GAD-65 expression was similar to their effect on insulin secretion.
14 8781713 We found that: 1) IL-1 beta at low dose (1 U/ml) which stimulated insulin secretion, had no effect on GAD-65 expression, whereas higher doses of IL-1 beta (10, 100, 1000 U/ml) which inhibited insulin secretion, decreased GAD-65 expression. 2) TNF alpha at doses of 10, 100, 1000 U/ml which stimulated insulin secretion had no effect on GAD-65 expression. 3) IFN gamma at doses of 10, 100, 1000 U/ml had no effect on insulin secretion or on GAD-65 expression. 4) In combination, IL-1 beta plus TNF alpha and IFN gamma showed a similar inhibitory effect on GAD-65 expression as IL-1 beta alone.
15 8784069 The cytokine combination of interleukin-1 beta (50 U/mL), tumor necrosis factor-alpha (10(3) U/mL), and interferon-gamma (10(3) U/mL) induced significant increases in MDA and nitrite and significant decreases in insulin and DNA in islets after 60-h incubation.
16 9237797 When those cells were cultured and restimulated in vitro with the B-chain of insulin, we also observed a decrease in IFN-gamma expression and an increase in IL-4, TGF-beta and IL-10 expression.
17 10212230 Treatment of rat islets with poly(IC) + interferon-gamma (IFN-gamma) stimulates the time- and concentration-dependent expression of iNOS and production of nitrite by rat islets. iNOS expression and nitrite production by rat islets in response to poly(IC) + IFN-gamma correlate with an inhibition of insulin secretion and islet degeneration, effects that are prevented by the iNOS inhibitor aminoguanidine (AG).
18 10212230 Treatment of macrophage-depleted rat islets for 40 h with poly(IC) + IFN-gamma results in the expression of iNOS, production of nitrite, and inhibition of insulin secretion.
19 10212230 Poly IC + IFN-gamma stimulates iNOS expression and inhibits insulin secretion by primary beta-cells purified by fluorescence-activated cell sorting.
20 10212230 These results indicate that dsRNA + IFN-gamma interacts directly with beta-cells stimulating iNOS expression and inhibiting insulin secretion in a nitric oxide-dependent manner.
21 10967106 This was because these dysfunctions were induced by IFN-gamma alone, which decreased cellular insulin content and stimulated insulin exocytosis.

23 11108714 In combination, synthetic dsRNA (polyinosinic-polycytidylic acid, poly(I-C)) and interferon (IFN)-gamma stimulate inducible nitric-oxide synthase (iNOS) expression, inhibit insulin secretion, and induce islet degeneration.
24 11108714 Interleukin-1 (IL-1) appears to mediate dsRNA + IFN-gamma-induced islet damage in a nitric oxide-dependent manner, as the interleukin-1 receptor antagonist protein prevents dsRNA + IFN-gamma-induced iNOS expression, inhibition of insulin secretion, and islet degeneration.
25 11418698 Exacerbation of IDDM correlated with an increased frequency of IFN-gamma-secreting CD4(+) and CD8(+) T cells in response to insulin B chain-specific peptides compared with untreated mice.

27 11812737 RIP-Delta(gamma)R islets are resistant to IL-1 + IFN-gamma-induced inhibition of insulin secretion and DNA damage, indicating that beta-cell IFN-gamma responsiveness is required for IL-1 + IFN-gamma-mediated beta-cell damage.

29 12947309 Interferon (IFN)-gamma acts synergistically with interleukin (IL)-1beta and tumor necrosis factor (TNF)-alpha to activate isoform of nitric oxide synthetase (iNOS) gene expression, induce apoptosis, and impair glucose-stimulated insulin release (GSIR) in pancreatic islets.

32 9691088 Inhibition of iNOS activity by aminoguanidine also attenuates TNF + LPS + IFN-gamma-induced inhibition of insulin secretion by human islets.
33 11211190 We compared insulin secretion, islet cell death and survival, inducible nitric oxide synthase (iNOS) mRNA expression, nitrite production, and Bcl-2 and Bax mRNA expression in isolated human and large mammal (bovine) islets exposed to 50 U/ml recombinant human interleukin-1, 1,000 U/ml recombinant human tumor necrosis factor-alpha and 1,000 U/ml recombinant human interferon-gamma.

36 12031968 The presence of cFLIP prevented the weak TNF-alpha-induced reduction in cellular insulin content and secretion; however, it did not prevent the decrease in glucose-stimulated insulin secretion induced by the combined cytokines, in agreement with our previous data demonstrating that interferon-gamma alone could induce these beta-cell dysfunctions.
