1 7027249 Insulin-containing erythrocyte (ICE) number was reduced in patients with an evident form of diabetes mellitus and in 50% of patients of the 2nd group (less than 60%).
2 7439544 The 24-h integrated plasma concentration of glucose (IC-glucose), norepinephrine (IC-NE), epinephrine (IC-E), cortisol (IC-F), growth hormone (IC-GH), aldosterone (IC-ALDO), and plasma renin activity (IC-PRA) were measured in 11 nonobese juvenile-onset nonketotic diabetic patients exhibiting hyperglycemia and glycosuria and 34 matched control subjects using a portable pump, drawing blood at a constant rate through a nonthrombogenic i.v. catheter.
3 8613527 Chronic exposure of betaTC-6 cells to supraphysiologic concentrations of glucose decreases binding of the RIPE3b1 insulin gene transcription activator.
4 8613527 We have shown previously that chronic exposure of HIT-T15 cells to supraphysiologic glucose concentrations causes decreased insulin gene transcription and decreased binding activities of two beta-cell specific transcription factors, STF-1 and the RIPE3b1 activator, and have suggested that these events may provide a mechanism for glucose toxicity on beta-cell function.
5 8613527 Electromobility shift assays demonstrated that binding of a specific nuclear protein that recognizes the RIPE3b1 binding site of the insulin gene was markedly diminished in late passage cells chronically exposed to 11.1 mM glucose, whereas binding activities of STF-1 and ICE activators were unchanged.
6 8613527 Mutation of the RIPE3b1 binding site almost completely abolished insulin gene transcription as well as binding activity.
7 8613527 We conclude that chronic exposure of betaTC-6 cells to high glucose concentrations paradoxically decreases insulin gene transcription, in part, by decreasing activity of the trans-activating factor which binds to the RIPE3b1 sequence.
8 8613527 This study uniquely demonstrates that altered binding to the RIPE3b1 sequence mediates glucose toxicity in betaTC-6 cells, thus reinforcing the importance of this cis-acting element in the regulation of insulin gene transcription.
9 9218757 Protection of NIT-1 pancreatic beta-cells from immune attack by inhibition of NF-kappaB.
10 9218757 We have recently observed that inhibition of NF-kappaB in NIT-1 insulinoma cells protects them from tumour necrosis factor (TNF)-induced cell death in vitro, possibly because expression of interleukin-1 (IL-1)beta-converting enzyme (ICE), a member of the cysteine protease pathway of cell death, is decreased.
11 9218757 In the current study we have examined the effect of the same inhibitor of NF-kappaB on class I major histocompatibility complex (MHC) protein expression in NIT-1 cells and shown that inhibition of NF-kappaB activation decreased basal and TNF-induced class I MHC levels.
12 9218757 Although inducible nitric oxide synthase (iNOS) may also be inhibited by inhibition of NF-kappaB, this could not be demonstrated in NIT-1/delta sp cells because wild-type NIT-1 cells express very little iNOS.
13 9218757 When NIT-1/delta sp12 cells, expressing high levels of the NF-kappaB inhibitor, are transplanted into immunodeficient NOD/scid mice, tumorigenesis and death by hypoglycemia proceed similarly to untransfected NIT-1 cells.
14 9218757 In conclusion, inhibition of NF-kappaB is likely to suppress several different pathways of immune-mediated cell death in beta-cells and protects NIT-1 cells from immune attack by diabetogenic T cells in vivo.

135 11377701 IFNgamma increased lipopolysaccharide (LPS)-induced IL-18 production and caspase-1 expression, while PGE(2) inhibited LPS-induced IL-18 production.
136 11377701 A similar pattern of IL-18 regulation by IFNgamma and PGE(2) was observed at the mRNA level.
137 11377701 The regulation of microglial activation by IFNgamma and PGE(2) was accompanied by differential modulation of LPS-induced NF-kB activation.
138 11377701 While IFNgamma enhanced LPS-induced NF-kB activation, PGE(2) suppressed its activation.
139 14555214 Although distinct receptors, all members share a common cell signaling pathway that mediates the activation of nuclear factor-kappaB (NF-kappaB) and mitogen-activated protein kinases (e.g. c-jun N-terminal kinase).
140 14555214 Regulation of cell growth and activation of NF-kappaB and of c-jun N-terminal kinase by the TNF super family is mediated through sequential activation/association of a set of cell signaling proteins named TNF receptor-associated factors, Fas-associated death domain and FADD-like ICE, caspases, receptor-interacting protein, NF-kappaB-inducing kinases, and IkappaBalpha kinases.
141 14561487 The JNK binding domain of islet-brain 1 inhibits IL-1 induced JNK activity and apoptosis but not the transcription of key proapoptotic or protective genes in insulin-secreting cell lines.
142 14561487 The stress-activated protein kinase c-Jun NH2-terminal kinase (JNK) is a central signal for interleukin-1beta (IL-1beta)-induced apoptosis in insulin-producing beta-cells.
143 14561487 The cell-permeable peptide inhibitor of JNK (JNKI1), that introduces the JNK binding domain (JBD) of the scaffold protein islet-brain 1 (IB1) inside cells, effectively prevents beta-cell death caused by this cytokine.
144 14561487 To define the molecular targets of JNK involved in cytokine-induced beta-cell apoptosis we investigated whether JNKI1 or stable expression of JBD affected the expression of selected pro- and anti-apoptotic genes induced in rat (RIN-5AH-T2B) and mouse (betaTC3) insulinoma cells exposed to IL-1beta.
145 14561487 Inhibition of JNK significantly reduced phosphorylation of the specific JNK substrate c-Jun (p<0.05), IL-1beta-induced apoptosis (p<0.001), and IL-1beta-mediated c-fos gene expression.
146 14561487 However, neither JNKI1 nor JBD did influence IL-1beta-induced NO synthesis or iNOS expression or the transcription of the genes encoding mitochondrial manganese superoxide dismutase (MnSOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase rho (GSTrho), heat shock protein (HSP) 70, IL-1beta-converting enzyme (ICE), caspase-3, apoptosis-inducing factor (AIF), Bcl-2 or Bcl-xL.
147 14592444 Tumor necrosis factor-alpha (TNF-alpha) is a cytokine considered to play a key role in beta-cell destruction in insulin-dependent diabetes mellitus (IDDM).
148 14592444 Expression of TNF receptor I, inducible form of nitric oxide synthase (iNOS), interleukin-1 beta-converting enzyme (ICE), Bcl-2, and nuclear factor kappa B (NF-kappa B) was analyzed by reverse transcriptase-polymerase chain reaction to investigate the suppressor mechanism of FTS on TNF-alpha-induced apoptosis.
149 14592444 FTS treatment suppressed the expression of iNOS and Bcl-2 mRNA in TNF-alpha-treated cells.
150 14592444 The expression of NF-kappa B mRNA in TNF-alpha-treated cells was enhanced after FTS treatment, while that of ICE mRNA did not change in TNF-alpha-treated cells with or without FTS treatment.
151 14592444 These results suggest that the inhibition of MIN6 cell death by FTS on TNF-alpha-induced apoptosis is caused by a negative feedback mechanism involving the inhibition of iNOS induction.

154 14592444 FTS treatment suppressed the expression of iNOS and Bcl-2 mRNA in TNF-alpha-treated cells.
155 14592444 The expression of NF-kappa B mRNA in TNF-alpha-treated cells was enhanced after FTS treatment, while that of ICE mRNA did not change in TNF-alpha-treated cells with or without FTS treatment.
156 14592444 These results suggest that the inhibition of MIN6 cell death by FTS on TNF-alpha-induced apoptosis is caused by a negative feedback mechanism involving the inhibition of iNOS induction.
157 14693703 Interleukin (IL)-1 beta and IL-18 are two cytokines associated with the immunopathogenesis of diabetes in NOD mice.
158 14693703 IL-1 is a proinflammatory cytokine linked to beta-cell damage, and IL-18 stimulates production of interferon (IFN)gamma in synergy with IL-12.
159 14693703 Casp1(-/-) bone marrow-derived macrophages stimulated with lipopolysaccharide produced no detectable IL-18, fourfold lower IL-1 beta, and 20-30% less IL-1 alpha than macrophages from wild-type Casp1(+/+) or Casp1(+/-) controls.
160 14693703 Unexpectedly, despite reduced IL-1 and IL-18, there was no change in the rate of diabetes or in total incidence as compared with that in wild-type NOD mice.

184 17267571 Importantly, recovery from the behavioral consequences of hypoxia-induced NSA was nearly ablated in MyD88 (myeloid differentiation factor 88) knock-out mice and in mice intracerebroventricularly administered the caspase-1 inhibitor ac-YVAD-CMK (ac-Tyr-Val-Asp-2,6-dimethylbenzoyloxymethylketone).
185 17267571 Diabetic mice had prolonged recovery from NSA that could be halved by administration of subcutaneous interleukin-1 (IL-1) receptor antagonist (RA).
186 17267571 These results show that acute hypoxia activates the IL-1beta arm of the neuroimmune system, which diabetes exacerbates and treatment with IL-1RA ameliorates.
187 18263705 Glucose and leptin induce apoptosis in human beta-cells and impair glucose-stimulated insulin secretion through activation of c-Jun N-terminal kinases.
188 18263705 c-Jun N-terminal kinases (SAPK/JNKs) are activated by inflammatory cytokines, and JNK signaling is involved in insulin resistance and beta-cell secretory function and survival.
189 18263705 Chronic high glucose concentrations and leptin induce interleukin-1beta (IL-1beta) secretion from pancreatic islets, an event that is possibly causal in promoting beta-cell dysfunction and death.
190 18263705 The present study provides evidence that chronically elevated concentrations of leptin and glucose induce beta-cell apoptosis through activation of the JNK pathway in human islets and in insulinoma (INS 832/13) cells.
191 18263705 JNK inhibition by the dominant inhibitor JNK-binding domain of IB1/JIP-1 (JNKi) reduced JNK activity and apoptosis induced by leptin and glucose.
192 18263705 Exposure of human islets to leptin and high glucose concentrations leads to a decrease of glucose-induced insulin secretion, which was partly restored by JNKi.
193 18263705 We detected an interplay between the JNK cascade and the caspase 1/IL-1beta-converting enzyme in human islets.
194 18263705 Similarly, cultured human islets exposed to high glucose- and leptin-induced caspase 1 and JNK inhibition prevented this up-regulation.
195 18263705 Therefore, JNK inhibition may protect beta-cells from the deleterious effects of high glucose and leptin in diabetes.
196 18263705 Glucose and leptin induce apoptosis in human beta-cells and impair glucose-stimulated insulin secretion through activation of c-Jun N-terminal kinases.
197 18263705 c-Jun N-terminal kinases (SAPK/JNKs) are activated by inflammatory cytokines, and JNK signaling is involved in insulin resistance and beta-cell secretory function and survival.

203 18263705 Similarly, cultured human islets exposed to high glucose- and leptin-induced caspase 1 and JNK inhibition prevented this up-regulation.
204 18263705 Therefore, JNK inhibition may protect beta-cells from the deleterious effects of high glucose and leptin in diabetes.
205 18274606 These changes include upregulation of iNOS, COX-2, ICAM-1, caspase 1, VEGF, and NF-kappaB, increased production of nitric oxide, prostaglandin E2, IL-1beta, and cytokines, as well as increased permeability and leukostasis.
206 19494813 T cells dampen innate immune responses through inhibition of NLRP1 and NLRP3 inflammasomes.
207 19494813 Here we show that mouse effector and memory CD4(+) T cells abolish macrophage inflammasome-mediated caspase-1 activation and subsequent interleukin 1beta release in a cognate manner.
208 19494813 Inflammasome inhibition is observed for all tested NLRP1 (commonly called NALP1) and NLRP3 (NALP3 or cryopyrin) activators, whereas NLRC4 (IPAF) inflammasome function and release of other inflammatory mediators such as CXCL2, interleukin 6 and tumour necrosis factor are not affected.
209 19494813 Suppression of the NLRP3 inflammasome requires cell-to-cell contact and can be mimicked by macrophage stimulation with selected ligands of the tumour necrosis factor family, such as CD40L (also known as CD40LG).
210 19494813 In a NLRP3-dependent peritonitis model, effector CD4(+) T cells are responsible for decreasing neutrophil recruitment in an antigen-dependent manner.
211 19805629 Inflammasomes activate caspase-1 for processing and secretion of the cytokines interleukin-1beta (IL-1beta) and IL-18.
212 19805629 Glyburide's cyclohexylurea group, which binds to adenosine triphosphatase (ATP)-sensitive K(+) (K(ATP)) channels for insulin secretion, is dispensable for inflammasome inhibition.
213 19805629 Glyburide analogues inhibit ATP- but not hypothermia-induced IL-1beta secretion from human monocytes expressing familial cold-associated autoinflammatory syndrome-associated Cryopyrin mutations, thus suggesting that inhibition occurs upstream of Cryopyrin.
214 19805629 Therefore, glyburide is the first identified compound to prevent Cryopyrin activation and microbial ligand-, DAMP-, and crystal-induced IL-1beta secretion.
215 20331890 IL-18 is found in the unstable atherosclerotic plaque, in adipose tissue and in muscle tissue, and is subject to several regulatory steps including cleavage by caspase-1, inactivation by IL-18 binding protein and the influence of other cytokines in modulating its interaction with the IL-18 receptor.
216 20370652 The ability of SIRT1 to avert apoptosis employs the activation of protein kinase B (Akt1), the post-translational phosphorylation of the forkhead member FoxO3a, the blocked trafficking of FoxO3a to the nucleus, and the inhibition of FoxO3a to initiate a "pro-apoptotic" program as shown by complimentary gene knockdown studies of FoxO3a.
217 20370652 Vascular apoptotic oversight by SIRT1 extends to the direct modulation of mitochondrial membrane permeability, cytochrome c release, Bad activation, and caspase 1 and 3 activation, since inhibition of SIRT1 activity and gene knockdown of SIRT1 significantly accentuate cascade progression while SIRT1 activation abrogates these apoptotic elements.
218 20370652 Our work identifies vascular SIRT1 and its control over early apoptotic membrane signaling, Akt1 activation, post-translational modification and trafficking of FoxO3a, mitochondrial permeability, Bad activation, and rapid caspase induction as new avenues for the treatment of vascular complications during DM.
219 21217695 The NLRP3 inflammasome instigates obesity-induced inflammation and insulin resistance.
220 21217695 The Nod-like receptor (NLR) family of innate immune cell sensors, such as the nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (Nlrp3, but also known as Nalp3 or cryopyrin) inflammasome are implicated in recognizing certain nonmicrobial originated 'danger signals' leading to caspase-1 activation and subsequent interleukin-1β (IL-1β) and IL-18 secretion.
221 21217695 We show that calorie restriction and exercise-mediated weight loss in obese individuals with type 2 diabetes is associated with a reduction in adipose tissue expression of Nlrp3 as well as with decreased inflammation and improved insulin sensitivity.
222 21217695 We further found that the Nlrp3 inflammasome senses lipotoxicity-associated increases in intracellular ceramide to induce caspase-1 cleavage in macrophages and adipose tissue.
223 21217695 Ablation of Nlrp3 in mice prevents obesity-induced inflammasome activation in fat depots and liver as well as enhances insulin signaling.
224 21217695 Furthermore, elimination of Nlrp3 in obese mice reduces IL-18 and adipose tissue interferon-γ (IFN-γ) expression, increases naive T cell numbers and reduces effector T cell numbers in adipose tissue.
225 21217695 Collectively, these data establish that the Nlrp3 inflammasome senses obesity-associated danger signals and contributes to obesity-induced inflammation and insulin resistance.

233 21270263 Hyperglycemia activates caspase-1 and TXNIP-mediated IL-1beta transcription in human adipose tissue.
234 21478880 Interleukin (IL)-1β plays a role in insulin resistance, yet how IL-1β is induced by the fatty acids in an HFD, and how this alters insulin signaling, is unclear.
235 21478880 We show that the saturated fatty acid palmitate, but not unsaturated oleate, induces the activation of the NLRP3-ASC inflammasome, causing caspase-1, IL-1β and IL-18 production.
236 21478880 This pathway involves mitochondrial reactive oxygen species and the AMP-activated protein kinase and unc-51-like kinase-1 (ULK1) autophagy signaling cascade.
237 21478880 Furthermore, IL-1β affects insulin sensitivity through tumor necrosis factor-independent and dependent pathways.
238 21523780 Limited proteolysis can take place extracellularly by serine proteases, released in particular by infiltrating neutrophils or intracellularly by the cysteine protease caspase-1.
239 21566058 As a new entry, the inflammasome-forming NLR genes integrate various danger signals into caspase-1-activating platforms that regulate the processing and secretion of pro-IL-1β and pro-IL-18 into the mature and active cytokines.
240 21566058 Accumulating data now document a role for the NLRP3 inflammasome and IL-1β/IL-18 in many diseases, including atherosclerosis, diabetes, amyloidosis, malaria, crystal-related diseases, and other autoinflammatory disorders, identifying this innate immune pathway as an attractive therapeutic target.
241 21566058 Here we review the current knowledge regarding inflammasome signaling and outline existing evidence on the expression and functional role of the inflammasome-caspase-1-IL-1β/IL-18 axis in kidney disease.
242 21566058 As a new entry, the inflammasome-forming NLR genes integrate various danger signals into caspase-1-activating platforms that regulate the processing and secretion of pro-IL-1β and pro-IL-18 into the mature and active cytokines.

244 21566058 Here we review the current knowledge regarding inflammasome signaling and outline existing evidence on the expression and functional role of the inflammasome-caspase-1-IL-1β/IL-18 axis in kidney disease.
245 22235789 We analyzed 14 single nucleotide polymorphisms (SNPs) within 7 inflammasome genes (NLRP1, NLRP3, NLRC4, AIM2, CARD8, CASP1, IL1B) in 144 patients affected by systemic lupus erythematosus and in 158 healthy controls from Southern Brazilian (state of São Paulo) with the aim of disclosing the possible role of inflammasome genes in the susceptibility of SLE.
246 22411934 NLRP3 activates inflammatory caspases, mostly caspase-1, which cleave the inactive precursors of IL-1β and IL-18 and stimulate their secretion.
247 22500248 Activation of these specific sets of receptors leads to the assembly of a multiprotein complex, the inflammasome, leading to the activation of caspase-1 and maturation of the cytokines interleukin (IL)-1β, IL-18, and IL-33.
248 22701621 In this study, we used streptozotocin (STZ)-induced diabetic nephropathy model with hyperuricemia and dyslipidemia in rats, and found over-expression of renal inflammasome components NLRP3, apoptosis-associated speck-like protein and Caspase-1, resulting in elevation of IL-1β and IL-18, with subsequently deteriorated renal injury.
249 23040364 It was subsequently observed that several of these conditions were caused by mutations in proteins involved in the innate immune response, including, among others, components of the NLRP3 inflammasome, cytokine receptors (tumour necrosis factor receptor 1 (TNFR1)) and receptor antagonists (interleukin 1 receptor antagonist (IL-1RA)).
250 23040364 NLRP3 inflammasome activation is induced by islet amyloid polypeptides (IAPPs) in T2D and this condition may, in future, be more commonly treated with targeted anti-cytokine therapies.
251 23040364 Caspase 1 activation and release of IL-1β/IL-1 family members is central to the pathogenesis of many autoinflammatory syndromes, as evidenced by the effectiveness of anti-IL-1 biologics in treating these disorders.
252 23066025 Multiple binding sites on the pyrin domain of ASC protein allow self-association and interaction with NLRP3 protein.
253 23066025 A key process underlying an innate immune response to pathogens or cellular stress is activation of members of the NOD-like receptor family, such as NLRP3, to assemble caspase-1-activating inflammasome complexes.
254 23066025 ASC interacts with NLRP3 via a homotypic PYD interaction and recruits procaspase-1 via a homotypic caspase recruitment domain interaction.
255 23066025 Here we demonstrate that ASC PYD contains two distinct binding sites important for self-association and interaction with NLRP3 and the modulatory protein POP1.
256 23066025 Furthermore, a type I binding mode is likely conserved in interactions with NLRP3 and POP1, because residues critical for interaction of ASC PYD are conserved in these PYDs.
257 23066025 We also demonstrate that ASC PYD can simultaneously self-associate and interact with NLRP3, rationalizing the model whereby ASC self-association upon recruitment to NLRP3 promotes clustering and activation of procaspase-1.
258 23086037 In this study, we investigated patterns of NLRP3 inflammasome activation in monocyte-derived macrophages (MDMs) from drug-naïve patients with newly diagnosed type 2 diabetes.
259 23086037 Type 2 diabetic subjects had significantly increased mRNA and protein expression of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), and proinflammatory cytokines in MDMs cultured with autologous sera compared with healthy controls.
260 23086037 Upregulated interleukin (IL)-1β maturation, IL-18 secretion, and caspase-1 cleavage were observed in MDMs from type 2 diabetic patients after stimulation with various danger molecules (ATP, high-mobility group protein B1, free fatty acids, islet amyloid polypeptide, and monosodium uric acid crystals).
261 23086037 Mitochondrial reactive oxygen species and NLRP3 were required for IL-1β synthesis in MDMs.
262 23086037 Finally, 2 months of therapy with the antidiabetic drug metformin significantly inhibited the maturation of IL-1β in MDMs from patients with type 2 diabetes through AMP-activated protein kinase (AMPK) activation.
263 23103566 In the kidney, HFCS-55 enhanced the expression of the NLRP3 (nucleotide-binding domain and leucine-rich-repeat-protein 3) inflammasome complex, resulting in caspase-1 activation and interleukin-1β production.
264 23349493 We show that ablation of galectin-3 (Gal-3), a galactoside-binding lectin, accelerates high-fat diet-induced obesity and diabetes.
265 23349493 Obese LGALS3(-/-) mice have increased body weight, amount of total visceral adipose tissue (VAT), fasting blood glucose and insulin levels, homeostasis model assessment of insulin resistance, and markers of systemic inflammation compared with diet-matched wild-type (WT) animals.
266 23349493 VAT of obese LGALS3(-/-) mice exhibited increased incidence of type 1 T and NKT lymphocytes and proinflammatory CD11c(+)CD11b(+) macrophages and decreased CD4(+)CD25(+)FoxP3(+) regulatory T cells and M2 macrophages.
267 23349493 Pronounced mononuclear cell infiltrate, increased expression of NLRP3 inflammasome and interleukin-1β (IL-1β) in macrophages, and increased accumulation of advanced glycation end products (AGEs) and receptor for AGE (RAGE) expression were present in pancreatic islets of obese LGALS3(-/-) animals accompanied with elevated phosphorylated nuclear factor-κB (NF-κB) p65 and mature caspase-1 protein expression in pancreatic tissue and VAT.
268 23349493 In vitro stimulation of LGALS3(-/-) peritoneal macrophages with lipopolysaccharide (LPS) and saturated fatty acid palmitate caused increased caspase-1-dependent IL-1β production and increased phosphorylation of NF-κB p65 compared with WT cells.
269 23349493 Transfection of LGALS3(-/-) macrophages with NLRP3 small interfering RNA attenuated IL-1β production in response to palmitate and LPS plus palmitate.
270 23349493 We show that ablation of galectin-3 (Gal-3), a galactoside-binding lectin, accelerates high-fat diet-induced obesity and diabetes.

276 23382179 Nuclear localization leucine-rich-repeat protein 1 (NLRP1) is a key regulator of the innate immune system, particularly in the skin where, in response to molecular triggers such as pathogen-associated or damage-associated molecular patterns, the NLRP1 inflammasome promotes caspase-1-dependent processing of bioactive interleukin-1β (IL-1β), resulting in IL-1β secretion and downstream inflammatory responses.
277 23382179 Functionally, we found that peripheral blood monocytes from healthy subjects homozygous for the predominant high-risk haplotype 2A processed significantly greater (P < 0.0001) amounts of the IL-1β precursor to mature bioactive IL-1β under basal (resting) conditions and in response to Toll-like receptor (TLR) agonists (TLR2 and TLR4) compared with monocytes from subjects homozygous for the reference haplotype 1.
