|
Since the Fas antibody showed no cross-reactive activity of tumour necrosis factor (TNF), the cytotoxic effect was not mediated by TNF receptors.
|

|
The Fas-mediated killing of islet cells was not L-arginine-dependent, or blocked by N(G)-monomethyl-L-arginine. beta-TC1 cells also expressed Fas mRNA when exposed to IL-1 alpha or IL-1 alpha plus interferon-gamma.

Like pancreatic beta cells, betaTC-3 cells do not constitutively express Fas, but Fas expression can be induced with IL-1 and IFN-gamma.
|
6 |
10811232
|
After IL-1/IFN-gamma treatment, betaTC-3 cells transfected with the anti-Fas ribozyme expressed 80% less Fas compared with mock-transfected cells.

|
Activation of T cells through the T-cell receptor (TCR) induces the expression of Fas Ligand (CD95L).
|
9 |
11165713
|
In turn, CD95L binds to the Fas receptor (CD95) and rapidly induces apoptosis in cycling cells.

|
The defect was apparent in vivo as well as in vitro, was independent of IAbetag7 expression and affected both Fas-dependent and Fas-independent pathways of apoptosis; for Fas-dependent apoptosis, the defective tolerance of NOD thymocytes correlated with the strong T cell receptor-mediated up-regulation of caspase 8-homologous FLICE (Fas-associated death-domain-like interleukin 1beta-converting enzyme)-inhibitory protein.

|
The delivery of transgenes capable of interfering with antigenic recognition and/or cell death [e.g., Fas ligand (FasL), Bcl-2, Bcl-XL] as well as imparting tolerance/immunoregulation [e.g., interleukin(IL)-4, IL-10, transforming growth factor (TGF)-beta], or cytoprotection [e.g., heme oxygenase-1 (HO-1), catalase, manganese superoxide dismutase (MnSOD)] may prevent recurrent type 1 diabetes in islet transplantation and offer a promising form of immunotherapy.

This induction of Fas was not dependent upon p53, because p53 is not expressed in an active form in either HL-60 or MOLT-4 cells.

15 |
12579793
|
Angiotensin converting enzyme inhibitor benazepril showed some renal protective effect on diabetic nephropathy, partly through inhibiting apoptosis by down-regulating Fas and Fas-L expression.
|
16 |
12588112
|
Here we investigate whether Fas ligand (Fas-L) expression by testicular Sertoli cells is responsible for this additional protective effect.
|
17 |
12658358
|
The immunohistochemistry and RT-PCR assay showed a higher level of Fas expression and Fas mRNA in the cataracts with DR than in the senile cataracts, although there was no difference in the expression level of the Fas ligand, Bcl-2, and their mRNAs between both groups.

|
In normal islets, insulin + cells accounted for (59.37 +/- 1.21)%, and some islet cells were observed expressing Fas.

|
Following the onset of streptozotocin-induced diabetes, FasL expression was increased in rat neutrophils (P<0.005) and was accompanied by a simultaneous increase in Fas expression in the retinal vasculature.

|
The cell line NIT-1 responded to the interleukin (IL)-1beta+interferon (IFN)-gamma stimulus with translocation of Fas to the cell surface.

Fas expression is thought to be induced by proinflammatory cytokines, such as IL-1beta, interferon-gamma (IFNgamma), and TNFalpha, released by islet-infiltrating mononuclear cells.
|
22 |
15033908
|
To determine whether beta-cells can modulate their sensitivity to apoptosis at the level of Fas, we investigated the effect of Fas ligand (FasL) on surface expression of Fas in NIT-1 insulinoma cells from nonobese diabetic (NOD) mice prone to autoimmune diabetes and islet cells from NOD and nonautoimmune BALB/c mice.
|
23 |
15033908
|
In NIT-1 insulinoma cells, Fas expression induced by the cytokine combination IL-1beta and IFNgamma was reduced in the presence of FasL, whereas in islet cells Fas expression was unaffected by FasL.
|
24 |
15033908
|
The effect of FasL on NIT-1 cells was evident during and after the induction of Fas expression by IL-1beta and IFNgamma.
|
25 |
15033908
|
Thus, FasL down-regulates cytokine-induced Fas expression in NOD mouse-derived NIT-1 cells, but not in NOD or BALB/c mouse islets.
|
26 |

|
32 |

Lymphocytic infiltration to the exocrine pancreatic tissue was observed only in fulminant T1D, whereas immunologically abnormal findings, such as increased expression of MHC class I molecule and Fas antigen in islet cells and Fas-ligand expression in infiltrating lymphocytes, were detected only in autoimmune T1D.
|
40 |
19203089
|
The inflammatory infiltrate consists primarily of T lymphocytes; CD8 cells outnumber CD4 cells, there are fewer B lymphocytes and macrophages are relatively scarce. beta cell death may involve the Fas apoptotic pathway since they have been shown to express Fas, infiltrating T lymphocytes express Fas-L and apoptotic beta cells have been described.

45 |
20541824

From these data, we concluded that 1) NO is required for cytokine-induced hsp 70 mRNA expression but not for Fas and MnSOD expression, 2) cytokines induce both apoptosis and necrosis in mouse beta-cells, and 3) cytokine-induced apoptosis is mostly NO-independent, whereas necrosis requires NO formation.

IL-1beta inhibits beta cell function and promotes Fas-triggered apoptosis in part by activating the transcription factor NF-kappaB.
|
70 |
12235117
