Acromegaly is characterized by growth hormone (GH) and insulin-like growth factor 1 (IGF1) excess and is accompanied by an increased cardiovascular diseases (CVD) risk.
|

28611056
|
The underlying signalling pathways were investigated by the inhibition of downstream targets of the IGF1 receptor.
|

|
GH did not affect TLR-induced cytokine production, but co-stimulation with IGF1 dose dependently increased the TLR ligand-induced production of IL6 (P < 0.01), TNF alpha (P = 0.02) and IFNg (P < 0.01), as well as the production of the anti-inflammatory cytokine IL10 (P = 0.01).

|
IGF1 had no effect on IL1B, IL17 and IL22 production.
|
5 |
28611056
|
Inhibition of the MAPK pathway, but not mTOR, completely abrogated the synergistic effect of IGF1 on the LPS-induced IL6 and TNF alpha production.

Resistin Gene Expression is Downregulated in CD4(+) T Helper Lymphocytes and CD14(+) Monocytes in Rheumatoid Arthritis Responding to TNF-α Inhibition.

|
Resistin [resistance to insulin; (RETN)] is an inflammatory cytokine, first discovered in murine adipocytes.
|

27434862
|
Accordingly, we measured RETN, IFN-γ, TNF-β, IL-1β, TNF-α, TGF-β and IL-10 gene expressions in CD14(+) monocytes, CD4(+) T helper (Th) lymphocytes (ly), CD8(+) T cytotoxic (Tc) ly and CD19(+) B ly in active RA before and 3 months after start of TNF-αI.
|
9 |
27434862
|
We found that TNF-αI caused a significant downregulation of RETN gene expression in CD14(+) monocytes and CD4(+) Th ly and was unchanged in CD8(+) Tc ly and CD19(+) B ly.
|
10 |
27434862
|
Both in active RA and during TNF-αI, RETN mRNA levels were significantly higher in CD14(+) monocytes than in all other examined cell types.

NKG2D, junctional adhesion molecule-like protein and 2B4 are demonstrated to participate in DETCs activation, except for ligands of T lymphocytes receptor.
|

Effective DETCs secrete cytokines such as interferon-γ, insulin-like growth factor-2, keratinocyte growth factor and gain cytotoxicity to directly kill tumor cells.

Pluripotency genes including Oct-4, Sox-2, and Nanog as well as proliferation-associated immunomodulatory cytokines such as insulin-like growth factor 1 (IGF-1) and transforming growth factor-β (TGF-β) expression were evaluated using real-time PCR.

Although we observed a strong induction of LCN2 expression and secretion from white adipose tissue (WAT) depots, the induction of LCN2 varied among different insulin-sensitive tissues.
|

|
Knockdown experiments also demonstrated that STAT1 is required for IFNγ-induced lipocalin-2 expression in murine adipocytes.
|
16 |
24391115
|
ERK activation-induced serine phosphorylation of both STAT1 and p65 mediated the additive effects of IFNγ and TNFα on LCN2 expression.
|
17 |
24391115
|
Our results suggest that these same mechanisms occur in humans as we observed STAT1 and NF-κB binding to the human LCN2 promoter in chromatin immunoprecipitation assays performed in human fat cells.

Protection against diabetes was accompanied by histone hyperacetylation in pancreas and spleen, enhanced frequency of CD4(+) CD62L(+) cells in the spleen, reduction in cellular infiltration of islets, restoration of normoglycemia and glucose-induced insulin release by beta cells.

Activation of splenic T lymphocytes derived from protected mice in vitro with pharmacological agents that bypass the antigen receptor or immobilized anti-CD3 antibody resulted in enhanced expression of Ifng mRNA and protein without altering the expression of Il4, Il17, Il18, Inos and Tnfa genes nor the secretion of IL-2, IL-4, IL-17 and TNF-α proteins.
|

21321581
|
Consistently, expression of the transcription factor involved in Ifng transcription, Tbet/Tbx21 but not Gata3 and Rorgt, respectively, required for the transcription of Il4 and Il17, was upregulated in activated splenocytes of protected mice.

IFNG-inducible KYN/pteridines inflammation cascade is characterized by up-regulation of nitric oxide synthase (NOS) activity (induced by KYN) and decreased formation of NOS cofactor, BH4, that results in uncoupling of NOS that shifting arginine from NO to superoxide anion production.

IFNG-induced up-regulation of indoleamine 2,3-dioxygenase (IDO), rate-limiting enzyme of TRY-KYN pathway, decreases TRY conversion into serotonin (substrate of antidepressant effect) and increases production of KYN associated with diabetes [xanthurenic acid (XA)], anxiety (KYN), psychoses and cognitive impairment (kynurenic acid).

|
In addition to literature data on KYN/TRY ratio (IDO activity index), we observe neopterin levels (index of activity of rate-limiting enzyme of guanine-BH4 pathway) to be higher in carriers of high (T) than of low (A) producers alleles; and to correlate with AAMPD markers (e.g., insulin resistance, body mass index, mortality risk), and with IFN-alpha-induced depression in hepatitis C patients.

The present study was conducted to explore the source of acetylcholine (ACH) in the corpus luteum (CL) and to test our hypothesis of an antiapoptotic role of ACH in the bovine CL and, further, to investigate whether nerve growth factor (NGF), insulin-like growth factor 1 (IGF1), and transforming growth factor beta1 (TGFB1) influence the expression of choline acetyltransferase (CHAT), the biosynthetic enzyme of ACH, in cultured bovine luteal cells.

|
Cell viability and TUNEL assays were performed on cultured midluteal cells treated with or without tumor necrosis factor alpha (TNF)/interferon gamma (IFNG) in the presence of ACH and its muscarinic (atropine) and nicotinic (mecamylamine) receptor antagonists.

ACH increased cell viability and prevented cell death induced by TNF/IFNG.
|

TNF/IFNG treatment downregulated CHAT expression, whereas NGF, IGF1, and TGFB1 upregulated CHAT expression, in cultured luteal cells.

We show that IGF1 delays neutrophil apoptosis triggered by the agonistic anti-Fas antibody CH11 and that the effect of IGF1 is comparable in magnitude to that of the acknowledged anti-apoptotic cytokines interferon-gamma (IFNG) and granulocyte-macrophage colony-stimulating factor (GM-CSF; now known as CSF2).

PDX-1 and Msx-2 expression in the regenerating and developing pancreas.
|
76 |
10588826
|
Importantly, we have found that PDX-1, a transcription factor required for insulin gene transcription as well as for pancreatic development during embryogenesis, is expressed in the duct cells of IFNg mice.
|
77 |
10588826
|
This striking observation suggests an important role for PDX-1 in the marked regeneration observed in IFNg mice, paralleling its critical function during ontogeny.
|
78 |
10588826
|
Also demonstrated was elevated expression of the homeobox-containing protein Msx-2 in the pancreata of fetal mice as well as in adult IFNg mice, identifying this molecule as a novel marker associated with pancreatic development and regeneration as well.
|
79 |
10588826
|
The identification of PDX-1 and Msx in the ducts of the IFNg transgenic pancreas but not in the ducts of the non-transgenic pancreas suggests that these molecules are associated with endocrine precursor cells in the ducts of the IFNg transgenic mouse.
