NK cells are the first line of defense against infected and transformed cells. Defective NK cell activity was shown to increase susceptibility for viral infections and reduce tumor immune-surveillance.

We found an increased frequency of NK cells with high expression of the inhibitory killer cell lectin-like receptor G1 (KLRG1) in individuals |70 y. The role of KLRG1 in ageing is not known, and the mechanism of KLRG1-induced inhibition of NK cell function is not fully understood. We report that NK cells with high KLRG1 expression spontaneously activate the metabolic sensor AMP-activated protein kinase (AMPK) and that activation of AMPK negatively regulates NK cell function. Pre-existing AMPK activity is further amplified by ligation of KLRG1 in these cells, which leads to internalization of the receptor and allows interaction with

Leukocyte immunoglobulin-like receptor subfamily B member 3 is a protein that in humans is encoded by the LILRB3 gene. This gene is a member of the leukocyte immunoglobulin-like receptor (LIR) family, which is found in a gene cluster at chromosomal region 19q13.4. The encoded protein belongs to the subfamily B class of LIR receptors which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and two to four cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). The receptor is expressed on immune cells where it binds to MHC class I molecules on antigen-presenting cells and transduces a negative signal that inhibits stimulation of an immune response. It is thought to control inflammatory responses and cytotoxicity to help focus the immune response and limit autoreactivity. Multiple transcript variants encoding different isoforms have been found for this gene. Cluster of differentiation ENSG00000274587, ENSG00000277816, ENSG00000204577 GRCh38: Ensembl ...

Clone REA1016 recognizes the mouse killer cell lectin-like receptor G1 (KLRG1) antigen. KLRG1 is a homodimeric type II transmembrane glycoprotein of 30-38 kDa subunits. The protein is the mouse homolog of the rat mast cell function-associated antigen (MAFA) and is expressed on a subset of NK cells and T cells. Several members of the cadherin family can interact with KLRG1 leading to inhibition of NK cell and T cell effector functions. Additional information: Clone REA1016 displays negligible binding to Fc receptors. - Belgique

As shown by RNA in situ hybridization in rat (supplemental Figs. 1A-C, 3A, available at www.jneurosci.org as supplemental material) as well as in mouse (data not shown) embryos, Slit2 and Slit3 are highly expressed around the eye in E13 rat and E11.5 mouse embryos (which represent developmentally equivalent stages in the two species). Because Slit1 is not detected there, we first examined Slit2;Slit3 mutant embryos (n = 4). We found that the bottom structure was unaffected in the mutant, but the top structure was dramatically reduced in size when compared with stage-matched littermates (Fig. 1 B). The ratio of the top and the bottom branching areas was reduced by twofold to 0.69 ± 0.30 in the double mutants (Fig. 1 C), and this reduction reflects a change in both branching and neurite growth, because the ratio of the number of branching points or the ratio of branch lengths is also reduced to 0.61 ± 0.36 or 0.56 ± 0.23, respectively, in the mutant from 1.16 ± 0.34 or 1.27 ± 0.22 in the wild ...

Results. The serum sRAGE (pg/ml) level was significantly lower in patients compared to healthy controls [515 (64-1887) vs 1542 (627-3159); p , 0.0001]. In paired samples, SF had lower levels compared to corresponding plasma level [102 (51-799) vs 481 (134-1006); p , 0.0001]. The level of S100A12 (ng/ml) was higher in SF (1042; 573-1415) than serum (638; 208-779). Serum sRAGE correlated negatively with S100A12 levels (r = −0.474; p , 0.01.), ESR (r = −0.306; p , 0.01), and SJC (r = −0.237; p , 0.05), but not with TJC (r = −0.134; p = NS). The levels of sRAGE remained stable over time in patients with stable disease. ...
Eric, madwifi-lists, I have been able to avoid the AP crashing by using another version of madwifi (I tried using voyage-0.6.5 which contains madwifi in version madwifi-trunk 0.9.4+r4099 as mentioned in the link posted by Eric). It really seemed to be a problem which overloaded the CPU. I come up with this idea, because I have a small display attached via serial line to the ALIX-AP-board and the display was really dull once the error occurred, but sometimes it still reacted - S-L-O-W-L-Y. So now, the error is gone, no more crashing - at least during the last 5 hours, but since the problem usually occurred within 20 minutes, I am very confident. Using a newer version of madwifi solved it. BUT now, I see something else. I am still loading the link heavily with the scp I mentioned before. Roundabout 6 minutes after booting the two ALIX-boards, the connection becomes very laggy. I am pinging the machine, that I am doing the scp to with the very same machine, that does the scp and the ping-times go ...

Advanced glycation end products (AGEs) are critically involved in atherogenesis in diabetes by binding to receptors for AGE (RAGEs) in vascular cells, thus inducing the expression of proinflammatory mediators. In animal models, interruption of the AGE-RAGE interaction reduces lesion size and plaque development. Therefore, limiting RAGE expression might be an intriguing concept to modulate vascular disease in diabetic patients. The present study investigated whether thiazolidinediones (TZDs), antidiabetic agents clinically used to treat patients with type 2 diabetes, might modulate endothelial RAGE expression. Stimulation of human endothelial cells with rosiglitazone or pioglitazone decreased basal as well as tumor necrosis factor-α-induced RAGE cell surface and total protein expression. In addition, TZDs reduced RAGE mRNA expression in endothelial cells. These effects on RAGE expression were caused by an inhibition of nuclear factor-κB (NF-κB) activation at the proximal NF-κB site of the ...

This is the second in a series of articles designed to provide important information about key metabolic processes that are really important to understand for optimizing our quality of life - and yet almost no one in the general public has any awareness of them at all.. The first article addressed methylation: an important biochemical process in our bodies that is important for many health issues. Here is a link to the article.. This article addresses another very important metabolic process:. Advanced Glycation End Products (AGEs).. What exactly are Advanced Glycation End Products (AGEs)? Here is a great description of what AGEs are:. Advanced Glycation End Products (AGEs) are basically the nasty by-products of glucose metabolism. The typical Western Diet, coupled with a sedentary lifestyle, too much fat, and insulin resistance, leaves our bodies churning out excess glucose and unable to burn it. It stays in our blood stream too long and there it does incredible damage.. One of the most ...
Clearance of apoptotic cells by macrophages and other phagocytic cells, called efferocytosis, is a central process in the resolution of inflammation. Although the receptor for advanced glycation end products (RAGE) has been shown to participate in a variety of acute and chronic inflammatory processes in the lungs and other organs, a role for RAGE in efferocytosis has not been reported. In the present studies, we examined the potential involvement of RAGE in efferocytosis. Macrophages from transgenic RAGE-/- mice showed a decreased ability to engulf apoptotic neutrophils and thymocytes. Pretreatment of RAGE+/+ macrophages with advanced glycation end products, which competitively bind to RAGE, or Abs against RAGE diminished phagocytosis of apoptotic cells. Overexpression of RAGE in human embryonic kidney 293 cells resulted in an increased ability to engulf apoptotic cells. Furthermore, we found that incubation with soluble RAGE enhances phagocytosis of apoptotic cells by both RAGE+/+ and RAGE-/- ...

This study was conducted to clarify the role of RAGE in nondiabetic atherosclerosis. We used the aortic and coronary atherosclerotic lesions of Watanabe heritable hyperlipidemic (WHHL) rabbits prone to myocardial infarction (WHHLMI) at 1 to 14 months. Immunohistochemistry demonstrated the significant expression of RAGE as early as at 1 month with the stronger expression at 3 and 7 ...

Blood-based immunoglobulins (IgGs) may mark the presence of amyloid plaques characterizing the progression of Alzheimers disease (AD). Previous studies suggest that anti-RAGE and anti-Aβ IgGs increase proportionately with accumulation of amyloid-beta (Aβ) peptides at receptor sites for advanced glycation end products (RAGE), within cortical areas of brain tissue. We assessed the relationship between these potential markers and an AD-type cognitive profile. We hypothesized that these specific IgG levels would be positively correlated with Clinical Dementia Rating (CDR) scores as well as index scores on the Repeatable Battery for the ...
Determine if an acute glucose load (50g) is associated with an in-vivo and in-vitro increase in the concentration of Advanced Glycation End Products (AGEPs) that, in turn, can impact vascular endothelial reactivity and induce an acute increase in blood pressure. Previous studies generated in the investigators laboratory showed that circulating soluble Receptor for Advanced Glycation End Products (sRAGE) and Tumor Necrosis Factor (TNF)-a (mediator of acute inflammation) are considered markers of the extent of maternal RAGE activation and/or systemic inflammation, respectively ...
To the best of our knowledge, our study is the first to demonstrate an association between plasma sRAGE levels and CAD in nondiabetic males. The multivariate-adjusted ORs for CAD revealed that male subjects with sRAGE levels below 776 pg/dL had a 6.719-fold increase in CAD prevalence, independent of established vascular risk factors and lipid parameters. Notably, the independent association between sRAGE levels and CAD was confirmed when analyzing a subgroup of patients with normal levels of LDL cholesterol. This finding appears of interest, because it is estimated that up to half of all CAD cases occur in subjects with moderate to low risk as determined by evaluation of LDL and total cholesterol.3. sRAGE is a soluble receptor produced by alternative splicing of RAGE mRNA21 and is abundantly present in the circulation.22 The mechanism by which plasma sRAGE levels were decreased in CAD patients, however, remains to be clarified. Because sRAGE has been shown to successfully bind to AGEs,30 it has ...
The receptor for advanced glycation end products (RAGE) is a member of the immunoglobulin superfamily of cell surface molecules. As a pattern-recognition receptor capable of binding a diverse range of ligands, it is typically expressed at low levels under normal physiological conditions in the majority of tissues. In contrast, the lung exhibits high basal level expression of RAGE localised primarily in alveolar type I (ATI) cells, suggesting a potentially important role for the receptor in maintaining lung homeostasis. Indeed, disruption of RAGE levels has been implicated in the pathogenesis of a variety of pulmonary disorders including cancer and fibrosis. Furthermore, its soluble isoforms, sRAGE, which act as decoy receptors, have been shown to be a useful marker of ATI cell injury. Whilst RAGE undoubtedly plays an important role in the biology of the lung, it remains unclear as to the exact nature of this contribution under both physiological and pathological conditions.
To assess regulation of cell surface expression of ICAM-1 by the interaction of AGEs with RAGE, HSVEC were incubated with AGE albumin. A dose-dependent increase in cell surface expression of ICAM-1 was noted compared with native albumin (Figure 4b, lanes 2, 3, 4, and 1, respectively). This effect was mediated at least in part by RAGE, as demonstrated by decreased AGE-mediated expression of ICAM-1 in the presence of anti-RAGE IgG but not by nonimmune IgG (Figure 4b, lanes 7 and 8, respectively). In vivo-derived uremic AGEs had similar effects; compared with native albumin, incubation of HSVECs with uremic AGEs resulted in an ≈1.7-fold increase in cell surface expression of ICAM-1 (Figure 4b, lanes 9 and 10, respectively). These effects were mediated in part by RAGE, as demonstrated by reduced expression of ICAM-1 in the presence of anti-RAGE IgG but not by nonimmune IgG (Figure 4b, lanes 11 and 12, respectively).. Because E-selectin mediates targeting of inflammatory cells, particularly ...
We have recently shown that the co-expression and interaction of the receptor for advanced glycation end products (RAGE) and its ligand S100B post myocardial infarction play a role in myocyte apoptosis. In other cell types, the S100B/RAGE interaction triggers signaling pathways including NF-kB activation and translocation, MAP kinases, and p53. To determine the signaling pathways modulated by the S100B/RAGE interaction contributing to myocyte apoptosis, rat neonatal cardiac myocyte cultures transfected with a full-length cDNA of the RAGE gene, a dominant-negative cytoplasmic deletion mutant of RAGE, or vector control were treated with nanomolar (1-1000) concentrations of recombinant bovine brain S100B for 48 hrs. 1 μM S100B induced vector alone-transfected myocyte apoptosis, as evidenced by increased terminal deoxynucleotidyltransferase-mediated UTP end labeling (TUNEL) [12.4±0.7% vs. 5.6±0.3% (untreated) of total cells p,0.05], DNA fragmentation, cytochrome C release from the mytochondria to ...
BACKGROUND/AIMS:Our previous report showed that IgG levels are strongly correlated with the indocyanine green (ICG) retention rate in patients with liver cirrhosis (LC). This correlation suggests that hyperglobulinemia in LC could be explained by impairment of hepatic removal function. To estimate IgG turnover in LC, in the present paper was determined the advanced glycation end-products (AGE) on IgG as a marker of half-life.METHODOLOGY:Serum samples were obtained from patients with LC, rheumatoid arthritis (RA), and Sjögren syndrome (SjS), and from age-matched control patients. IgG was purified from serum by the protein G-based affinity method, concentrated by filtration, and used for assay of Nepsilon-(carboxymethyl) lysine (CML), a predominant AGE, by ELISA.RESULTS:CML on IgG was significantly lower in patients with LC than in control patients, whereas there was no significant difference in total serum CML levels among patients with LC, RA, and SjS, and control patients. CML levels on IgG ...
I have recently read an interesting article in Diabetes Care (1) that showed that the low serum level of the endogenous secretory receptor for advanced glycation end products (esRAGE) was independently associated with the prevalence of vertebral fractures in patients with type 2 diabetes. I totally agreed with the authors opinions that bone quality may be more important than bone density in defining the increased risk for fracture in type 2 diabetic patients and that the advanced glycation end product (AGE)-receptor for AGEs (RAGE) system could play a role in impaired bone quality in these patients. However, it seemed unlikely to me that an insufficient amount of esRAGE to counteract AGEs could intensify the binding of AGEs to RAGE and exert harmful effects on bones, thus being involved in the increased risk of vertebral fractures in their patients.. The endogenous soluble form of RAGE (sRAGE) can generate from the cleavage of cell surface full-length RAGE by sheddase or novel splice variants ...
Advanced glycation end products (AGEs) have been introduced to be involved in the pathogenesis of osteoarthritis (OA). The influence of AGEs on osteoarthritic fibroblast-like synovial cells (FLS) has been incompletely understood as yet. The present study investigates a potential influence of AGE-modified bovine serum albumin (AGE-BSA) on cell growth, and on the expression of proinflammatory and osteoclastogenic markers in cultured FLS. FLS were established from OA joints and stimulated with AGE-BSA. The mRNA expression of p27Kip1, RAGE (receptor for AGEs), nuclear factor kappa B subunit p65 (NFκB p65), tumor necrosis factor alpha (TNF-α, interleukin-6 (IL-6), receptor activator of NFκB ligand (RANKL) and osteoprotegerin was measured by real-time PCR. The respective protein expression was evaluated by western blot analysis or ELISA. NFκB activation was investigated by luciferase assay and electrophoretic mobility shift assay (EMSA). Cell cycle analysis, cell proliferation and markers of necrosis and

This gene is a member of the Roundabout (ROBO) gene family that controls neurite outgrowth, growth cone guidance, and axon fasciculation. ROBO proteins are a subfamily of the immunoglobulin transmembrane receptor superfamily. SLIT proteins 1-3, a family of secreted chemorepellants, are ligands for ROBO proteins and SLIT/ROBO interactions regulate myogenesis, leukocyte migration, kidney morphogenesis, angiogenesis, and vasculogenesis in addition to neurogenesis. This gene, ROBO3, has a putative extracellular domain with five immunoglobulin (Ig)-like loops and three fibronectin (Fn) type III motifs, a transmembrane segment, and a cytoplasmic tail with three conserved signaling motifs: CC0, CC2, and CC3 (CC for conserved cytoplasmic). Unlike other ROBO family members, ROBO3 lacks motif CC1. The ROBO3 gene regulates axonal navigation at the ventral midline of the neural tube. In mouse, loss of Robo3 results in a complete failure of commissural axons to cross the midline throughout the spinal cord ...
Mouse gp49 was formerly identified on mast and NK cells. However, in previous studies, only cells cultured in cytokines were examined. In this study, we provide the first comprehensive analysis of the distribution of gp49 on naive, hemopoietic cells. Unexpectedly, we find that resting NK cells lack expression of gp49. Instead, myeloid cells from bone marrow, spleen, and liver, expressing Mac-1 and Gr-1, constitutively express gp49A and B. By contrast, T cells as well as B cells do not express gp49.. Despite that gp49 is not found on naive NK cells, it is induced on NK cells following in vitro and in vivo stimulation. This induced expression is found in NK cell responses to MCMV infection, a notable observation because of the critical role of NK cells in controlling lethality and replication by MCMV (19, 20, 23). Although the mechanism for induction of gp49 expression was not revealed in our studies, NK cells from MCMV-infected IL-12 or IFN-γ-deficient mice were fully capable of gp49 expression. ...

The triggering receptor expressed on myeloid cells-1 (TREM-1) is a member of the immunoglobulin superfamily, and its expression is upregulated on phagocytic cells in the presence of bacteria or fungi (1). Several experiments by Bouchon and colleagues showed that TREM-1 mediates the acute inflammatory response to microbial products. Human tissues infected with bacteria are infiltrated with neutrophils and macrophages that express high levels of TREM-1. Conversely, TREM-1 is only weakly expressed in samples from patients with noninfectious inflammatory disorders. In addition, TREM-1 is shed from the membrane of activated phagocytes and can be found in a soluble form in body fluids. The presence of a soluble form of TREM-1 in samples of bronchoalveolar lavage fluid from mechanically ventilated patients has been shown to be a good indicator of infectious pneumonia. During sepsis, a progressive decline of plasma sTREM-1 concentration indicates a favorable clinical evolution during the recovery phase ...
We evaluated the heart using pre- and after-load-independent indices of LV function and found that the blockage of RAGE in diabetic mice from the age of 7 to 12 weeks prevented the development of cardiac dysfunction. dp/dt, which is a complex function influenced by pre- and after-load, was unaffected.[27] Consequently, blockage of RAGE must improve cardiac function by a direct action in the heart.. The function of the heart is dependent on the biophysical properties of the myocardium. As a result, AGE cross-linking has specific consequences for cardiac function. In accordance with this, accumulation of collagen and alterations in myocardial collagen AGEs in the diabetic heart have been demonstrated to decrease myocardial compliance.[15],[28] We found that RAGE blockage normalized LV diastolic chamber stiffness. In addition, the mRNA expression of Col1a1 was normalized in RAGE-blocked diabetic mice. These data indicate that RAGE activation mediates increased collagen AGE formation, which leads to ...

Interaction of RAGE with its ligands can promote tumor progression, invasion and angiogenesis. Although blocking RAGE signaling has been proposed as a potential anti-cancer strategy, functional contributions of RAGE expression in the tumor microenvironment (TME) has not been investigated in detail. Here, we evaluated the effect of genetic depletion of RAGE in TME on the growth of gliomas. In both invasive and non-invasive glioma models, animal survival was prolonged in RAGE knockout (Ager-/-) mice. However, the improvement in survival in Ager-/- mice was not due to changes in tumor growth rate but rather to a reduction in tumor-associated inflammation. Furthermore, RAGE ablation in the TME abrogated angiogenesis by downregulating the expression of pro-angiogenic factors which prevented normal vessel formation, thereby generating a leaky vasculature. These alterations were most prominent in non-invasive gliomas, where the expression of VEGF and pro-inflammatory cytokines were also lower in ...

In the current study, we report a crucial role for TLT-1 in regulating leukocyte activation and modulating sepsis-induced acute inflammatory response. A 17-aa residue of its extracellular domain mediates this effect. Whereas treml-1−/− mice are particularly susceptible to infection with the development of an intense inflammatory state that translated into organ damage and rapid mortality, LR17 administration confers a strong protection.. Until recently, the role of TLT-1 has remained unclear. TLT-1 is exclusively expressed in platelets, colocalized with CD62P in α-granules of resting platelets. Upon activation, TLT-1 is quickly exposed on the membrane (24) and subsequently cleaved, leading to the release of a soluble fragment. Structural analysis of the extracellular domain of TLT-1 suggests the existence of several distinct potential ligand binding sites (27). The first TLT-1 ligand was recently identified to be fibrinogen, positioning TLT-1 as a regulator of hemostasis by facilitating ...
Receptor-Mediated Regulation of the Innate Immune System. Our laboratory studies the molecular regulation and function of multiple receptor systems involved the generation and propagation of the innate immune response with the goal of understanding how the innate immune system can be harnessed for the prevention of and/or treatment of cancer. More specifically, we have been studying the signal transduction of regulatory receptors of innate immune cells including monocytes/macrophages, natural killer (NK) cells, and most recently, platelets. Receptor systems recently or currently under study include the KIR and the TREM and TREM-Like Receptors. Recent findings have driven us to become interested in the regulation of innate cell metabolic pathways by these receptor systems and the pathways with which they interact..

OBJECTIVE Advanced glycation end products (AGEs) and their specific receptor, the receptor for AGEs (RAGE), play an important role in atherosclerosis. Recently, a soluble form of RAGE (sRAGE) has been identified in human serum. However, the role of sRAGE in cardiovascular disease is still controversial. There is no information on the association between simultaneous measurements of AGEs and sRAGE and vascular function. In this study, we evaluated the associations between serum levels of AGEs and sRAGE, ratio of AGEs to sRAGE, and vascular function. ...
