Moreover, in both NOD and B6 mice, CD4+ T cells were more resistant to PCD induced by IL-2 deprivation than CD8+ cells.
|
17 |

CD40 ligand (CD154) triggers a short-term CD4(+) T cell activation response that results in secretion of immunomodulatory cytokines and apoptosis.
|
20 |
10684857
|
Signals generated through CD28-B7 and CD40 ligand (CD40L)-CD40 interactions have been shown to be crucial for the induction of long-term allograft survivability.
|
21 |
10684857
|
To investigate potential mechanisms of CD40L-induced allograft acceptance, we coimmobilized hu5C8 with suboptimal amounts of anti-CD3 to stimulate CD4(+) T cells.
|
22 |
10684857
|
We now report that anti-CD3/CD40L costimulation results in CD28-independent activation and subsequent deletion of resting T cells.
|
23 |
10684857
|
Coligation of CD3 and CD40L increased expression of CD69, CD25, and CD54 on CD4(+) T cells.
|
24 |
10684857
|
We also found that costimulation with anti-CD3/CD40L resulted in enhanced production of interleukin (IL)-10, interferon gamma, and tumor necrosis factor alpha but not IL-2 or IL-6.
|
25 |
10684857
|
Consistent with that observation, anti-CD3/CD40L did not enhance the antiapoptotic proteins Bcl-2 and Bcl-xL.
|
26 |
10684857
|
Further, the addition of CD28 at 24 h failed to rescue those cells induced to die after costimulation with anti-CD3/CD40L.

We observed that transduction of the anti-apoptotic proteins Bcl-X(L) and PEA-15 fused to TAT/PTD prevented apoptosis induced by tumor necrosis factor-alpha in a pancreatic beta-cell line, indicating that TAT/PTD anti-apoptotic proteins retained their biological activity.
|
64 |

Stimulation of HAECs with gly-ox-HDL elicited a marked increase in caspase 3 activity and the expressions of active caspase 3 and caspase 9, whereas concomitant treatment with a caspase 3 inhibitor significantly blocked gly-ox-HDL-induced apoptosis of HAECs.
|
66 |
11563854
|
The increased expressions of Bax and Bad were detected in HAECs incubated for 24 h with gly-ox-HDL, but gly-ox-HDL failed to interfere with the expression of Bcl-2 and Bcl-x.

FcR-binding "classical" anti-CD3 mAb is a potent immunosuppressive drug that alters CD4(+) and CD8(+) T cell function in vivo via anergy induction and programmed cell death (PCD).
|
87 |
12538715

Polymerase chain reaction (PCR)-based transcriptional patterning confirmed the increased expression of Nix during human erythropoiesis with a pattern similar to that of Bcl-xL and glycophorin A and opposite that of Bcl-2.
|
110 |

L-PGDS (50 microg/ml) was able to significantly inhibit VSMC proliferation and DNA synthesis and induce the apoptotic genes bax, bcl-x, and ei24 in SHR but had no effect on WKY cells.
|
120 |
12684506
|
Furthermore, we examined the effect of L-PGDS incubation on insulin-stimulated Akt, glycogen synthase kinase-3beta (GSK-3beta), and ERK phosphorylation.
|
121 |
12684506
|
Unexpectedly, we found that when WKY cells were pretreated with L-PGDS, insulin could actually induce apoptosis and failed to stimulate Akt/GSK-3beta phosphorylation.
|
122 |
12684506
|
Insulin-stimulated ERK phosphorylation was unaffected by L-PGDS pretreatment in both cell lines.

Mice with 50% Pdx1, a homeobox gene critical for pancreatic development, had worsening glucose tolerance with age and reduced insulin release in response to glucose, KCl, and arginine from the perfused pancreas.
|
124 |
12697734
|
Surprisingly, insulin secretion in perifusion or static incubation experiments in response to glucose and other secretagogues was similar in islets isolated from Pdx1(+/-) mice compared with Pdx1(+/+) littermate controls.
|
125 |
12697734
|
Bcl(XL) and Bcl-2 expression were reduced in Pdx1(+/-) islets.
|
126 |
12697734
|
These results suggest that an increase in apoptosis, with abnormal regulation of islet number and beta cell mass, represents a key mechanism whereby partial PDX1 deficiency leads to an organ-level defect in insulin secretion and diabetes.

With the knowledge that hepatocyte growth factor (HGF) is a potent survival factor for a wide variety of cells, we hypothesized that supplementation of HGF may provide a novel strategy for protecting pancreatic beta cells from destructive death and for preserving insulin production.
|
128 |
12746445
|
In this study, we demonstrate that expression of the exogenous HGF gene preserved insulin excretion and mitigated hyperglycemia of diabetic mice induced by streptozotocin.
|
129 |
12746445
|
Consistently, HGF concomitantly increased serum insulin levels in diabetic mice.
|
130 |
12746445
|
Immunohistochemical staining revealed a marked preservation of insulin-producing beta cells by HGF in the pancreatic islets of the diabetic mice.
|

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.

135 |
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.
|
136 |
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.
|
137 |
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.

Insulin-like growth factor (IGF)-I/IGF-binding protein-3 complex: therapeutic efficacy and mechanism of protection against type 1 diabetes.
|
139 |
14617576
|
Administration of IGF-I either alone or as an IGF-I/IGFBP-3 complex reduced the severity of insulitis and delayed the onset of T1D in nonobese diabetic mice, but IGF-I/IGFBP-3 was significantly more effective.
|
140 |
14617576
|
Protection from T1D elicited by IGF-I/IGFBP-3 was mediated by up-regulated CCL4 and down-regulated CCL3 gene expression in pancreatic draining lymph nodes, activation of the phosphatidylinositol 3-kinase and Akt/protein kinase B signaling pathway of beta-cells, reduced beta-cell apoptosis, and stimulation of beta-cell replication.
|
141 |
14617576
|
Reduced beta-cell apoptosis resulted from elevated Bcl-2 and Bcl-X(L) activity and diminished caspase-9 activity, indicating a novel role for a mitochondrial-dependent pathway of beta-cell death.
|
142 |
14617576
|
Thus, IGF-I/IGFBP-3 affords more efficient protection from insulitis, beta-cell destruction, and T1D than IGF-I, and this complex may represent an efficacious therapeutic treatment for the prevention of T1D.

LCPUFAs suppress the production of tumor necrosis factor-alpha (TNF-alpha) (and so also of OX40, since it belongs to the family of TNFR) and the expression of Bcl-2, suggesting that these fatty acids have the ability to prevent/suppress autoimmune diseases.
|
144 |
15114276
|
This indicates that LCPUFAs present in human breast milk suppress the levels of OX40 and decrease the expression of Bcl-xL and Bcl-2 on exposure to self-antigens and thus, protects against the development of autoimmune diseases in later life.

At 5-8 wk of age, even in the absence of TCRbeta expression, CD4+ and CD4+CD8+ blasts appear spontaneously.

155 |

They mimic normal beta selection by up-regulating germline TCR-Calpha transcripts, CD2, and Bcl-xL and down-regulating Bcl-2.

However, they fail to down-regulate transcription factors HEB-alt and Hes1 and initially express aberrantly high levels of Spi-B, c-kit (CD117), and IL-7Ralpha.

Rat islets treated with a cytokine combination (interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma) displayed a significant increase in islet cell apoptosis when the islets were incubated in 24.4 mM glucose compared with untreated islets at the same glucose concentration (13.07 +/- 1.78% vs 6.09 +/- 0.78%; P < 0.01) or islets incubated in 5.5 mM glucose concentration and cytokines (13.07 +/- 1.78% vs 8.04 +/- 1.56%; P < 0.05).

However, the expression of anti-apoptotic mediators such as bcl-2 and bcl-xL did not show any significant change.
|
159 |
15525583
|
These results suggest that cytokine- and STZ-mediated apoptotic effects on islet cells might be mediated by a glucose-induced hyperfunctional status and associated with an increase in Fas (Apo-1, CD-95) expression and no changes in the expression of the anti-apoptotic proteins bcl-xL and bcl-2.

Expression of the axotomy-responsive genes coding for growth-associated protein 43 (GAP-43), galanin, neuropeptide Y (NPY), pre-pro-vasoactive intestinal polypeptide (pre-pro-VIP), neuronal nitric oxide synthase (nNOS), protease nexin 1, heat-shock protein 27 (HSP 27) and myosin light chain kinase II (MLCK II) was unaffected in ganglia from diabetic rats compared to controls; thus, no axotomised phenotype was established.

Wortmannin suppressed betacellulin-induced Pax4 expression, implicating the phosphatidylinositol 3-kinase signaling pathway.
|
167 |
15596543
|
Adenoviral overexpression of Pax4 caused a 3.5-fold increase in beta-cell proliferation with a concomitant 1.9-, 4-, and 5-fold increase in Bcl-xL (antiapoptotic), c-myc, and Id2 mRNA levels, respectively.
|
168 |
15596543

Accordingly, Pax4 transactivated the Bcl-xL and c-myc promoters, whereas its diabetes-linked mutant was less efficient.

Bcl-xL activity resulted in altered mitochondrial calcium levels and ATP production, explaining impaired glucose-induced insulin secretion in transduced islets.

Adenovirus-mediated XIAP gene transfer reverses the negative effects of immunosuppressive drugs on insulin secretion and cell viability of isolated human islets.
|
187 |
15677500
|
All three agents induce a decrease of intracellular levels of Bcl-2 and Bcl-xL, with an increased level of Smac, indicating that they are capable of promoting a downregulation of anti-apoptotic factors and an accumulation of pro-apoptotic mediators.
|
188 |

In conclusion, the present study demonstrates that genetically modified human islets expressing XIAP are resistant to the negative effects of immunosuppressive drugs on insulin secretion and cell viability.

STAT5 activation by human GH protects insulin-producing cells against interleukin-1beta, interferon-gamma and tumour necrosis factor-alpha-induced apoptosis independent of nitric oxide production.

16214938
|
The proinflammatory cytokines interleukin-1beta (IL-1beta), interferon-gamma (IFN-gamma) and tumour necrosis factor-alpha (TNF-alpha) are toxic to pancreatic beta-cells and are implicated in the pathogenesis of type 1 diabetes.
|
201 |
16214938
|
We have previously found that GH and prolactin (PRL) stimulate both proliferation and insulin production in pancreatic beta-cells and rat insulin-producing INS-1 cells.
|
202 |
16214938
|
Here we report that human (h) GH can prevent the apoptotic effects of IL-1beta, IFN-gamma and TNF-alpha in INS-1 and INS-1E cells.
|
203 |
16214938
|
In order to identify possible targets for the STAT5-mediated protection of INS-1E cells, we studied the effect of hGH on activation of the transcription factors STAT1 and nuclear factor-kappaB (NF-kappaB) by IFN-gamma and IL-1beta+TNF-alpha respectively.
|
204 |
16214938
|
Gel retardation experiments showed that hGH affects neither IFN-gamma+TNF-alpha-induced STAT1 DNA binding nor IL-1beta and IFN-gamma+TNF-alpha-induced NFkappaB DNA binding.
|
205 |
16214938
|
The lack of influence of hGH on cytokine-mediated activation of STAT1 and NFkappaB is in accordance with the finding that hGH had only a minor effect on cytokine-induced inducible nitric oxide synthase (iNOS) gene expression and in fact augmented the IL-1beta-stimulated nitric oxide production.
|
206 |
16214938

As the anti-apoptotic Bcl-xL gene has been shown to harbour a STAT5-binding element we measured the expression of Bcl-xL as well as the pro-apoptotic Bax.

|
We found that hGH increased the Bcl-xL/Bax ratio both in the absence and in the presence of cytotoxic cytokines.
|

In conclusion, these results suggested that GH and PRL protect beta-cells against cytotoxic cytokines via STAT5-dependent mechanisms distal to iNOS activation possibly at the level of Bcl-xL.

The purpose of the present study was to determine the effect of HO-1 overexpression on mitochondrial transporters, cytochrome c oxidase, and anti-apoptotic proteins in diabetic rats (streptozotocin, (STZ)-induced type 1 diabetes).
|
234 |
16595661
|
The increase in HO-1 by CoPP administration was associated with a significant increase in the phosphorylation of AKT and levels of BcL-XL proteins.
|
235 |
16595661
|
These observations in experimental diabetes suggest that the cytoprotective mechanism of HO-1 against oxidative stress involves an increase in the levels of MCs and anti-apoptotic proteins as well as in cytochrome c oxidase activity.

Moreover, peptide treatment had distinct effects on expression of the anti-apoptotic protein Bcl-X(L) in TCR-transgenic CD8(+) T cells under lymphopenic versus lymphoreplete conditions.
|
237 |
16959961
|
Increased HO activity was also associated with a significant increase in the antiapoptotic signaling molecules Bcl-xl and phosphorylation of p38-mitogen-activated protein kinase but no significant increases in Bcl-2 or BAD proteins.

Syk is constitutively activated in primary tumors and B lymphoma cell lines and curcumin down-modulates Syk activity accompanied by down-regulation of Akt activation.

241 |
17508911
|
These novel findings provide a link between the increase in HO-1 activity, with its concurrent enhanced production of carbon monoxide (CO) and bilirubin, a decrease in infiltrated CD11c(+) dendritic cells and an increase in anti-apoptotic proteins, including RSK and BcL-xL, in the interdiction of the diabetic state.

The islets from cKO mice demonstrated hyperactivation of STAT3 and higher induction of Bcl-xL than did islets from WT mice, and SOCS3-deficient beta-cells were more resistant to apoptosis induced by STZ in vitro than were WT beta-cells.
|
245 |
17562326

These results suggest that enhanced STAT3 signaling protects beta-cells from destruction induced by a genotoxic stress and that STAT3/SOCS3 can be a potential therapeutic target for the treatment of type 1 diabetes.

|
We have previously shown that transgenic mice expressing mouse placental lactogen-1 (mPL1) in beta cells under the rat insulin II promoter (RIP) are resistant to the diabetogenic and cytotoxic effects of streptozotocin (STZ) in vivo.
|
251 |
17728251
|
The signaling pathway mediating this protective effect is the janus-activated-kinase-2/signal transducer and activator of transcription-5 (JAK2/STAT5) pathway.
|
252 |
17728251
|
This is demonstrated in INS-1 cells and primary mouse beta cells using three separate approaches, pharmacological inhibitors, JAK2-specific siRNAs and a dominant-negative STAT5 mutant.
|
253 |
17728251
|
We believe this is the first direct demonstration of lactogens mediating their protective effect through the JAK2/STAT5 pathway in the beta cell and through Bcl-XL in any cell type.

|
261 |

This study examined the effects of interleukin-1beta (IL-1beta), interferon-gamma (IFNgamma) and tumour necrosis factor alpha (TNFalpha) on a rat insulinoma cell line (RIN-r) in order to identify the core mechanism of cytokine-induced beta-cell death.

|
Treatment of cells with a combination of IL-1beta and IFNgamma (IL-1beta/IFNgamma)induced apoptotic cell death.
|
284 |
18081694
|
TNFalpha neither induced beta-cell death nor did it potentiate the effects of IL-1beta, IFNgamma or IL-1beta/IFNgamma .
|
285 |
18081694
|
The cytotoxic effect of IL-1beta/IFNgamma was associated with the expression of inducible nitric oxide synthase (iNOS) and production of nitric oxide.
|
286 |
18081694
|
The broad range caspase inhibitor, Boc-D-fmk, blocked IL-1beta/IFNgamma -induced caspase activity, but not nitric oxide production nor cell death.
|
287 |
18081694
|
IL-1beta/IFNgamma -induced apoptosis was accompanied by loss of mitochondrial membrane potential, release of cytochrome c and cleavage of pro-caspase-9, -7 and -3.
|
288 |
18081694
|
Transduction of cells with Ad-Bcl-X(L) blocked both iNOS and cytokine-mediated mitochondrial changes and subsequent apoptosis, downstream of nitric oxide.

Resveratrol has also been shown to activate various transcription factor (e.g; NFkappaB, STAT3, HIF-1alpha, beta-catenin and PPAR-gamma), suppress the expression of antiapoptotic gene products (e.g; Bcl-2, Bcl-X(L), XIAP and survivin), inhibit protein kinases (e.g; src, PI3K, JNK, and AKT), induce antioxidant enzymes (e,g; catalase, superoxide dismutase and hemoxygenase-1), suppress the expression of inflammatory biomarkers (e.g., TNF, COX-2, iNOS, and CRP), inhibit the expression of angiogenic and metastatic gene products (e.g., MMPs, VEGF, cathepsin D, and ICAM-1), and modulate cell cycle regulatory genes (e.g., p53, Rb, PTEN, cyclins and CDKs).

We assessed the expression of Bcl-2 family members at both mRNA and protein levels as well as the Caspase-3 activity, in order to investigate the occurrence of apoptosis in hippocampus of STZ-induced diabetic rats.
|
296 |
18923682
|
The expressions of Bcl-2, Bcl-x(L), and Bax mRNA and proteins were measured using RT-PCR and western blotting, respectively.
|
297 |
18923682
|
The result showed that mRNA and protein levels of Bcl-2 and Bcl-x(L) were lower in hippocampus of diabetic group than that of the control group, whereas expressions of Bax in hippocampus of diabetic rats were higher than that of controls at both mRNA and protein levels (P < .01).
|
298 |
18923682
|
Therefore, the induction of diabetes is associated with increased ratios of Bax/Bcl-2, Bax/Bcl-x(L), and increased caspase-3 activity in hippocampus which shows that apoptosis is favored in hippocampal region.

We studied the expression of a set of selected genes involved in apoptosis (Bcl2, Bclx(L), Bax, Bad, Bid, and CHOP), cytokine defense, (SOCS-1 and SOCS-3), or free radical protection (Hmox1, Cu/Zn-SOD, Mn-SOD, and Hsp70).
|
310 |
19177839
|
The expression of proapoptotic genes Bid and CHOP, as well as protective genes Bclx(L), Socs1, Socs3, Hmox1, and MnSod, was maximally increased 1 day after transplantation, and in most cases it remained increased 7 days later, indicating the presence of a protective response against cell damage.
|
311 |

Previous gain-of-function studies in the RIP1-Tag2 model of pancreatic islet carcinogenesis, involving uniform or focal/temporal over-expression of Bcl-x(L), demonstrated accelerated tumor formation and growth.
|
316 |
19209227
|
Other anti-apoptotic Bcl-2 family members were expressed but not substantively altered at the mRNA level in the Bcl-x-null tumors, suggestive of redundancy without compensatory transcriptional up-regulation.

Absence of caspase-3 protects pancreatic {beta}-cells from c-Myc-induced apoptosis without leading to tumor formation.
|
320 |
19213729
|
When suppression of apoptosis is achieved by overexpression of Bcl-x(L) in an inducible model of c-Myc activation, a full spectrum of tumor development, including distant metastasis, occurs.
|
321 |
19213729
|
To test whether caspase-3 is an essential mediator of apoptosis in this model of tumorigenesis, we generated caspase-3 knock-out mice containing the inducible c-myc transgene (c-Myc(+)Casp3(-/-)).
|
322 |
19213729
|
In contrast to Bcl-x(L)-overexpressing c-Myc(+) mice, c-Myc(+)Casp3(-/-) mice remained euglycemic for up to 30 days of c-Myc activation, and there was no evidence of tumor formation.
|
323 |
19213729
|
Interestingly, caspase-3 deletion also led to the suppression of proliferation, perhaps through regulation of the cell cycle inhibitory protein p27, suggesting a possible mechanism for maintaining a balance between suppression of apoptosis and excessive proliferation in the context of c-Myc activation.
|
324 |
19213729
|
Additionally, c-Myc-activated Casp3(-/-) mice were protected from streptozotocin-induced diabetes.
|

Our studies demonstrate that caspase-3 deletion confers protection from c-Myc-induced apoptosis and diabetes development without unwanted tumorigenic effects.

The p38 mitogen-activated protein kinase (MAPK) is activated during heart diseases that might be associated with myocardial damage and cardiac remodeling process.
|
334 |
19617408
|
The purpose of this study was to investigate the role of p38alpha MAPK after experimental diabetes by using transgenic (TG) mice with cardiac-specific expression of a dominant-negative mutant form of p38alpha MAPK.
|
335 |
19617408
|
In addition, diabetic TG mice had reduced cardiac myocyte diameter, content of cardiac fibrosis, LV tissue expressions of atrial natriuretic peptide, transforming growth factor beta1, and collagen III compared with diabetic NTG mice.
|
336 |
19617408
|
Moreover, LV expression of NADPH oxidase subunits, p22(phox), p67(phox), gp91(phox), and Nox4, reactive oxygen species and lipid peroxidation levels were significantly increased in diabetic NTG mice, but not in diabetic TG mice.
|
337 |
19617408
|
Furthermore, myocardial apoptosis, the number of caspase-3-positive cells, and the downregulation of antiapoptotic protein Bcl-X(L) were less in diabetic TG mice compared with diabetic NTG mice.
|
338 |
19617408
|
In conclusion, our data establish that p38alpha MAPK activity is required for cardiac remodeling after diabetes induction and suggest that p38alpha MAPK may promote cardiomyocyte apoptosis by downregulation of Bcl-X(L).

We detected expression of p65, Rel-B, p50, p105, p52, and the ribosomal protein S3 (rpS3) in human islet cells.
|
346 |
19706790
|
Among these, only p65 and rpS3 were translocated from the cytosolic to the nuclear fraction in response to cytokines.
|
347 |
19706790
|
This resulted in increased expression of c-Rel and inhibitory factor κB, increased κB-binding activity, and augmented protein levels of Bcl-X(L,) c-IAP2, and heat shock protein 72. c-Rel expression in human islet cells protected against cytokine-induced caspase 3 activation and cell death. c-Rel protected also against streptozotocin- and H(2)O(2)-induced cell death, in both intact rat islets and human islet cells.
|
348 |
19706790
|
We conclude that rpS3 participates in NF-κB signaling and that a genetic increase in the activity of the NF-κB subunit c-Rel results in protection against cell death in human islets.

PPAR-gamma, by increasing superoxide dismutase/catalase and decreasing nicotinamide adenine dinucleotide phosphate oxidase levels, attenuated ischemia-induced reactive oxygen species and subsequently alleviated the postischemic degradation of Bcl-2, Bcl-xl, and Akt.

We presently evaluated the role of the myeloid cell leukemia sequence 1 (Mcl-1), an antiapoptotic protein of the Bcl-2 family, in β-cells following exposure to well-defined β-cell death effectors, for example, pro-inflammatory cytokines, palmitate and chemical endoplasmic reticulum (ER) stressors.
|
351 |
20798690
|
All cytotoxic stresses rapidly and preferentially decreased Mcl-1 protein expression as compared with the late effect observed on the other antiapoptotic proteins, Bcl-2 and Bcl-xL.
|
352 |
20798690
|
This was due to ER stress-mediated inhibition of translation through eIF2α phosphorylation for palmitate and ER stressors and through the combined action of translation inhibition and JNK activation for cytokines.
|
353 |
20798690
|
Knocking down Mcl-1 using small interference RNAs increased apoptosis and caspase-3 cleavage induced by cytokines, palmitate or thapsigargin, whereas Mcl-1 overexpression partly prevented Bax translocation to the mitochondria, cytochrome c release, caspase-3 cleavage and apoptosis induced by the β-cell death effectors.

A kinase-independent role for unoccupied insulin and IGF-1 receptors in the control of apoptosis.
|
355 |
21139139
|
Insulin and insulin-like growth factor 1 (IGF-1) act as antiapoptotic hormones.
|
356 |
21139139
|
We found that, unexpectedly, double-knockout (DKO) cells that lacked both insulin and IGF-1 receptors (IR and IGF1R, respectively) were resistant to apoptosis induced through either the intrinsic or the extrinsic pathway.
|
357 |
21139139
|
This resistance to apoptosis was associated with decreased abundance of the proapoptotic protein Bax and increases in abundance of the antiapoptotic proteins Bcl-2, Bcl-xL, XIAP, and Flip.
|
358 |
21139139
|
Insulin and IGF-1 binding stimulates receptor tyrosine kinase activity and blocks apoptosis, whereas unliganded IR and IGF1R, acting through a mechanism independent of their catalytic activity, exert a permissive effect on cell death.

|
The total cell numbers of CD4(+) T cells and especially CD8(+) T cells in the spleen and pancreatic lymph node were increased in the Stat5b transgenic NOD mice.
|

|
Consistent with these findings, CD4(+) and CD8(+) T cells from the Stat5b transgenic NOD mice showed a higher proliferation capacity and up-regulation of multiple cytokines including IL-2, IFN-γ, TNF-α and IL-10 as well as anti-apoptotic gene Bcl-xl.
|

|
Furthermore, the number and proportion of CD4(+)CD25(+) regulatory T cells were significantly increased in transgenic mice although in vitro suppression ability of the regulatory T-cells was not affected by the transgene.
|

|
Our results suggest that Stat5b confers protection against diabetes in the NOD mice by regulating the numbers and function of multiple immune cell types, especially by up-regulating CD4(+)CD25(+) regulatory T cells.
