The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens.

Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p304)Macular Degeneration: Degenerative changes in the RETINA usually of older adults which results in a loss of vision in the center of the visual field (the MACULA LUTEA) because of damage to the retina.

Molecular uncoupling of fractalkine-mediated cell adhesion and signal transduction. Rapid flow arrest of CX3CR1-expressing cells is independent of G-protein activation. (1/353)

Fractalkine is a novel multidomain protein expressed on the surface of activated endothelial cells. Cells expressing the chemokine receptor CX3CR1 adhere to fractalkine with high affinity, but it is not known if adherence requires G-protein activation and signal transduction. To investigate the cell adhesion properties of fractalkine, we created mutated forms of CX3CR1 that have little or no ability to transduce intracellular signals. Cells expressing signaling-incompetent forms of CX3CR1 bound rapidly and with high affinity to immobilized fractalkine in both static and flow assays. Video microscopy revealed that CX3CR1-expressing cells bound more rapidly to fractalkine than to VCAM-1 (60 versus 190 ms). Unlike VCAM-1, fractalkine did not mediate cell rolling, and after capture on fractalkine, cells did not dislodge. Finally, soluble fractalkine induced intracellular calcium fluxes and chemotaxis, but it did not activate integrins. Taken together these data provide strong evidence that CX3CR1, a seven-transmembrane domain receptor, mediates robust cell adhesion to fractalkine in the absence of G-protein activation and suggest a novel role for this receptor as an adhesion molecule.  (+info)

Characterization of fractalkine in rat brain cells: migratory and activation signals for CX3CR-1-expressing microglia. (2/353)

Molecular analyses of the chemokine fractalkine and its receptor CX3C-R1 in the rat brain have revealed a striking polarization: fractalkine is expressed constitutively in neurons and is up-regulated by TNF-alpha and IL-1beta in astrocytes. Expression of its specific receptor, CX3C-R1, is restricted to astrocytes and microglia. We have analyzed the functional correlates of this expression and demonstrate that fractalkine induces microglial cell migration and activation. However, the activity of this chemokine on astrocytes may also be highly relevant in inducing astrocyte-microglia cell interactions through cytokine/mediator release leading to microglial activation.  (+info)

Inflammatory agents regulate in vivo expression of fractalkine in endothelial cells of the rat heart. (3/353)

Fractalkine is distinguished structurally from other chemokines in that it contains a mucin-like stalk that tethers a CX3C chemokine module to a transmembrane-spanning region; its expression in cultured endothelial cells has been shown to be up-regulated by tumor necrosis factor alpha (TNF-alpha) and interleukin-1 (IL-1). The purpose of this study was to determine whether fractalkine is expressed, in a proinflammatory agent-regulated manner, by cardiac endothelial cells in vivo. Steady state levels of fractalkine mRNA were increased in rat cardiac tissues after in vivo treatment with lipopolysaccharide (LPS), IL-1, or TNF-alpha. In situ hybridization and immunohistochemical analysis revealed that endothelial cells of the coronary vasculature and endocardium were the principal source of proinflammatory agent-inducible fractalkine, although some fractalkine immunoreactivity was also found on the myocytes. These data are the first demonstration of in vivo cardiac endothelial cell fractalkine expression and regulation by proinflammatory agents such as LPS, IL-1, or TNF-alpha. Cardiac endothelial cell-expressed fractalkine may contribute to the influx of leukocytes into the heart during inflammation.  (+info)

Neuronal fractalkine expression in HIV-1 encephalitis: roles for macrophage recruitment and neuroprotection in the central nervous system. (4/353)

HIV-1 infection of the brain results in chronic inflammation, contributing to the neuropathogenesis of HIV-1 associated neurologic disease. HIV-1-infected mononuclear phagocytes (MP) present in inflammatory infiltrates produce neurotoxins that mediate inflammation, dysfunction, and neuronal apoptosis. Neurologic disease is correlated with the relative number of MP in and around inflammatory infiltrates and not viral burden. It is unclear whether these cells also play a neuroprotective role. We show that the chemokine, fractalkine (FKN), is markedly up-regulated in neurons and neuropil in brain tissue from pediatric patients with HIV-1 encephalitis (HIVE) compared with those without HIVE, or that were HIV-1 seronegative. FKN receptors are expressed on both neurons and microglia in patients with HIVE. These receptors are localized to cytoplasmic structures which are characterized by a vesicular appearance in neurons which may be in cell-to-cell contact with MPs. FKN colocalizes with glutamate in these neurons. Similar findings are observed in brain tissue from an adult patient with HIVE. FKN is able to potently induce the migration of primary human monocytes across an endothelial cell/primary human fetal astrocyte trans-well bilayer, and is neuroprotective to cultured neurons when coadministered with either the HIV-1 neurotoxin platelet activating factor (PAF) or the regulatory HIV-1 gene product Tat. Thus focal inflammation in brain tissue with HIVE may up-regulate neuronal FKN levels, which in turn may be a neuroimmune modulator recruiting peripheral macrophages into the brain, and in a paracrine fashion protecting glutamatergic neurons.  (+info)

Ultrastructure and function of the fractalkine mucin domain in CX(3)C chemokine domain presentation. (5/353)

Fractalkine (FKN), a CX(3)C chemokine/mucin hybrid molecule on endothelium, functions as an adhesion molecule to capture and induce firm adhesion of a subset of leukocytes in a selectin- and integrin-independent manner. We hypothesized that the FKN mucin domain may be important for its function in adhesion, and tested the ability of secreted alkaline phosphatase (SEAP) fusion proteins containing the entire extracellular region (FKN-SEAP), the chemokine domain (CX3C-SEAP), or the mucin domain (mucin-SEAP) to support firm adhesion under flow. CX3C-SEAP induced suboptimal firm adhesion of resting peripheral blood mononuclear cells, compared with FKN-SEAP, and mucin-SEAP induced no firm adhesion. CX3C-SEAP and FKN-SEAP bound to CX(3)CR1 with similar affinities. By electron microscopy, fractalkine was 29 nm in length with a long stalk (mucin domain), and a globular head (CX(3)C). To test the function of the mucin domain, a chimeric protein replacing the mucin domain with a rod-like segment of E-selectin was constructed. This chimeric protein gave the same adhesion of peripheral blood mononuclear cells as intact FKN, both when immobilized on glass and when expressed on the cell surface. This implies that the function of the mucin domain is to provide a stalk, extending the chemokine domain away from the endothelial cell surface to present it to flowing leukocytes.  (+info)

Fractalkine is an epithelial and endothelial cell-derived chemoattractant for intraepithelial lymphocytes in the small intestinal mucosa. (6/353)

Fractalkine is a unique chemokine that combines properties of both chemoattractants and adhesion molecules. Fractalkine mRNA expression has been observed in the intestine. However, the role of fractalkine in the healthy intestine and during inflammatory mucosal responses is not known. Studies were undertaken to determine the expression and function of fractalkine and the fractalkine receptor CX3CR1 in the human small intestinal mucosa. We identified intestinal epithelial cells as a novel source of fractalkine. The basal expression of fractalkine mRNA and protein in the intestinal epithelial cell line T-84 was under the control of the inflammatory mediator IL-1beta. Fractalkine was shed from intestinal epithelial cell surface upon stimulation with IL-1beta. Fractalkine localized with caveolin-1 in detergent-insoluble glycolipid-enriched membrane microdomains in T-84 cells. Cellular distribution of fractalkine was regulated during polarization of T-84 cells. A subpopulation of isolated human intestinal intraepithelial lymphocytes expressed the fractalkine receptor CX3CR1 and migrated specifically along fractalkine gradients after activation with IL-2. Immunohistochemistry demonstrated fractalkine expression in intestinal epithelial cells and endothelial cells in normal small intestine and in active Crohn's disease mucosa. Furthermore, fractalkine mRNA expression was significantly up-regulated in the intestine during active Crohn's disease. This study demonstrates that fractalkine-CX3CR1-mediated mechanism may direct lymphocyte chemoattraction and adhesion within the healthy and diseased human small intestinal mucosa.  (+info)

Rapid progression to AIDS in HIV+ individuals with a structural variant of the chemokine receptor CX3CR1. (7/353)

Human immunodeficiency virus (HIV) enters cells in vitro via CD4 and a coreceptor. Which of 15 known coreceptors are important in vivo is poorly defined but may be inferred from disease-modifying mutations, as for CCR5. Here two single nucleotide polymorphisms are described in Caucasians in CX3CR1, an HIV coreceptor and leukocyte chemotactic/adhesion receptor for the chemokine fractalkine. HIV-infected patients homozygous for CX3CR1-I249 M280, a variant haplotype affecting two amino acids (isoleucine-249 and methionine-280), progressed to AIDS more rapidly than those with other haplotypes. Functional CX3CR1 analysis showed that fractalkine binding is reduced among patients homozygous for this particular haplotype. Thus, CX3CR1-I249 M280 is a recessive genetic risk factor in HIV/AIDS.  (+info)

Fractalkine-mediated endothelial cell injury by NK cells. (8/353)

Endothelial cells (ECs) are primary targets of immunological attack, and their injury can lead to vasculopathy and organ dysfunction in vascular leak syndrome and in rejection of allografts or xenografts. A newly identified CX3C-chemokine, fractalkine, expressed on activated ECs plays an important role in leukocyte adhesion and migration. In this study we examined the functional roles of fractalkine on NK cell activity and NK cell-mediated endothelial cell injury. Freshly separated NK cells expressed the fractalkine receptor (CX3CR1) determined by FACS analysis and efficiently adhered to immobilized full-length fractalkine, but not to the truncated forms of the chemokine domain or mucin domain, suggesting that fractalkine functions as an adhesion molecule on the interaction between NK cells and ECs. Soluble fractalkine enhanced NK cell cytolytic activity against K562 target cells in a dose- and time-dependent manner. This enhancement correlated well with increased granular exocytosis from NK cells, which was completely inhibited by the G protein inhibitor, pertussis toxin. Transfection of fractalkine cDNA into ECV304 cells or HUVECs resulted in increased adhesion of NK cells and susceptibility to NK cell-mediated cytolysis compared with control transfection. Moreover, both enhanced adhesion and susceptibility of fractalkine-transfected cells were markedly suppressed by soluble fractalkine or anti-CX3CR1 Ab. Our results suggest that fractalkine plays an important role not only in the binding of NK cells to endothelial cells, but also in NK cell-mediated endothelium damage, which may result in vascular injury.  (+info)

We aimed to investigate fractalkine (CX3CL1) protein expression in wild type (wt) retina and its alterations during retinal degeneration in mouse model (rd10) of retinitis pigmentosa. Forms of retinal protein CX3CL1, total protein and mRNA levels of CX3CL1 were analyzed at postnatal days (P) 5, 10, 14, 22, 30, 45, and 60 by Western blotting and real-time PCR. Cellular sources of CX3CL1 were investigated by in situ hybridization histochemistry (ISH) and using transgenic (CX3CL1cherry) mice. The immunoblots revealed that in both, wt and rd10 retinas, a membrane integrated approximately 100 kDa CX3CL1 form and a cleaved approximately 85 kDa CX3CL1 form were present at P5. At P10, accumulation of another presumably intra-neuronal approximately 95 kDa form and a decrease in the approximately 85-kDa form were observed. From P14, a approximately 95 kDa form became principal in wt retina, while in rd10 retinas a soluble approximately 85 kDa form increased at P45 and P60. In comparison, retinas of rd10 mice had
N-Methyl-d-aspartate receptors (NMDARs) play fundamental roles in basic brain functions such as excitatory neurotransmission and learning and memory processes. Their function is largely regulated by factors released by glial cells, including the coagonist d-serine. We investigated whether the activation of microglial CX3CR1 induces the release of factors that modulate NMDAR functions. We recorded the NMDAR component of the field excitatory postsynaptic potentials (NMDA-fEPSPs) elicited in the CA1 stratum radiatum of mouse hippocampal slices by Shaffer collateral stimulation and evaluated d-serine content in the extracellular medium of glial primary cultures by mass spectrometry analysis. We demonstrated that CX3CL1 increases NMDA-fEPSPs by a mechanism involving the activity of the adenosine receptor type A2 (A2AR) and the release of the NMDAR coagonist d-serine. Specifically (1) the selective A2AR blocker 7-(2-phenylethyl)-5-amino-2-(2-furyl)-pyrazolo-[4,3-e]-1,2,4-triazolo[1

The mechanisms underlying peritoneal dissemination of ovarian carcinoma are poorly understood. Ovarian carcinoma is a malignancy with an exceptionally high mortality rate (1), largely due to the lack of effective antimetastatic treatment approaches. A more detailed understanding of the mechanisms underlying the formation and development of EOC metastases could offer insights into how late stages of this disease might be effectively targeted. Proteins that are presented on the cell surface have consistently been considered attractive molecular targets for disease treatment. Our data suggest that a member of GPCR family, the chemokine fractalkine receptor, functions to support the prometastatic properties of EOC cells, which include migration, peritoneal adhesion, and proliferation. In addition, the fractalkine chemokine can support cell proliferation through another receptor, EGFR. Our data support the hypothesis that multiple types of ovarian carcinoma rely on fractalkine signaling for disease ...
Maintenance and restoration of endothelial integrity are critical for blood vessel function. Endothelial cells (EC) form a monolayer in the inner surfaces of blood vessels that controls exchange of metabolites and regulates coagulation and cell trafficking. Cardiovascular diseases, such as atherosclerosis, vascular interventions, or bypass surgery, cause EC damage or overt defects in the endothelial monolayer, which triggers vascular inflammation, neointima formation, and ultimately vessel obstruction if endothelial integrity is not restored (Gimbrone & Garcia‐Cardena, 2016).. Under physiological conditions, EC replication is inhibited by cell contact and laminar flow (Akimoto et al, 2000; Chen et al, 2000). The loss of few cells is repaired rapidly by extension and spreading of adjacent EC without the need for proliferation (Reidy & Schwartz, 1981). However, larger EC lesions require proliferation to regenerate the endothelial monolayer and prevent neointima formation (Haudenschild & ...
Although anti-VEGF therapies are commonly used to treat macular degeneration, these angiogenesis inhibitors have also been approved to target tumor growth and metastasis in several cancers. Because tumors depend on access to circulating blood to grow and metastasize, preventing angiogenesis may limit cancer progression. The success of anti-VEGF therapies in cancer has been limited, however, due to the ability of tumors to rapidly develop treatment resistance.. This week in the JCI, a study led by Dai Fukumura at Harvard Medical School and Massachusetts General Hospital has determined that immunosuppressive effects of non-classical Ly6Clo monocytes contribute to resistance against anti-VEGF therapies in mouse models of colorectal cancer. Researchers observed that treating colorectal tumors with VEGF inhibitors led to elevated expression of the chemokine CX3CL1. Elevations in CX3CL1 levels enhanced the recruitment of Ly6Clo monocytes into tumors, which in turn increased neutrophil migration and ...
Fractalkine is a proinflammatory chemokine that participates in atherosclerotic process mediating the interactions of vascular cells and leukocytes and selective recruitment of Th1 lymphocytes, through interaction with CX3CR1 receptor. The polymorphism of the fractalkine receptor 280M-containing haplotype, which codifies for a receptor with minor expression and with a reduced binding capability, represents a novel protective factor of atherosclerotic disease. We investigated the association among CX3CR1 genotype, the inflammatory infiltrate subpopulations recruited in the plaque, and the in situ expression of fractalkine and its receptor, in patients who died of myocardial infarction (AMI) compared with subjects who died of noncardiac causes. Patients with nonlethal AMI (AMI survivors) were also investigated to correlate the CX3CR1 polymorphisms and the incidence of lethal AMI. A strong T cells
The findings presented here offer novel insights into the relative contribution of membrane-anchored versus soluble CX3CL1 signaling in the development of Aβ and MAPT pathologies in APPPS1 mice. Consistent with results from previous studies characterizing receptor knock-outs (Lee et al., 2010), APPPS1;Cx3cl1−/− mice exhibited reduced Aβ deposition at 4 months of age. However, despite this reduction in amyloid burden, CX3CL1 deficiency enhanced intraneuronal phospho-MAPT accumulation. Importantly, expression of obligate soluble CX3CL1 did not additionally alter the Aβ and MAPT phenotypes observed in APPPS1;Cx3cl1−/− animals, suggesting that membrane-anchored CX3CL1 selectively alters AD-related phenotypes in APPPS1 mice. Notably, microglia from APPPS1 mice lacking membrane-anchored CX3CL1 had increased levels of IL1α, IL6, and MSR1, which was consistent with increased activation of p38 MAPK and Aβ phagocytosis observed in these animals.. In addition to enhancing Aβ phagocytosis, ...

Epithelial ovarian carcinoma (EOC) is the deadliest gynecologic malignancy largely due to the metastatic disease. EOC metastases spread by shedding the malignant cells off of the ovarian surface and seeding tissues and organs of the peritoneal cavity. Currently used therapies, a combination of chemotherapy and surgery, fail to keep most patients in the remission. Mechanistic understanding of the biology of EOC metastasis will facilitate development of new therapeutic approaches. Our previous data demonstrated that fractalkine receptor (CX3CR1) is expressed by EOC cells and can support cell migration and proliferation. Moreover, our previous data suggested that CX3CR1-positive EOC cells can adhere to the CX3CL1-postive peritoneal mesothelial cells in in vitro assay. Thus, we hypothesized that CX3CL1/CX3CR1 axis could be important for peritoneal dissemination of metastatic EOC. To test this hypothesis, we performed short-term ex vivo and in vivo adhesion assay, as well as long-term metastasis ...
This study provides the first direct evidence that ATP can pass through Cx43 hemichannels. Three alternative approaches were used to evaluate the permeability of ATP through Cx43 hemichannels. First, we used inside-out patches with a pipette solution containing 130 mm Na2ATP, whereas the intracellular side of the patch was exposed to a pure sucrose solution. Under these conditions, frequent 26 pS channel openings were detected as outward currents in patches obtained from C6-Cx43+ cells (Fig. 6A). The outward current is generated by efflux of ATP anions, because passage of Na+ will result in an inward current. The VRev were −15 mV in these experiments, suggesting that the permeability of ATP2− is higher than Na+ (PNa/PATP = 1:2.5), because Na+ concentration was double of ATP2− concentration and sucrose has no charge.

N2 - The CX3C chemokine fractalkine (CX3CL1) exists as a membrane-expressed protein promoting cell-cell adhesion and as a soluble molecule inducing chemotaxis. Transmembrane CX3CL1 is converted into its soluble form by defined proteolytic cleavage (shedding), which can be enhanced by stimulation withphorbol-12-myristate-13-acetate (PMA). PMA-induced CX3CL1 shedding has been shown to involve the tumor necrosis factor-alpha-converting enzyme (TACE), whereas the constitutive cleavage in unstimulated cells remains elusive. Here we demonstrate a role of ...
Mycobacterium tuberculosis-induced cellular aggregation is essential for granuloma formation and may assist establishment and early spread of M. tuberculosis infection. The M. tuberculosis ESX1 mutant, which has a non-functional type VII secretion system, induced significantly less production of the host macrophage-derived chemokine fractalkine (CX3CL1). Upon infection of human macrophages ESX1-dependent fractalkine production mediated selective recruitment of CD11b+ monocytic cells and increased infection of neighbouring cells consistent with early local spread of infection. Fractalkine levels were raised in vivo at tuberculous disease sites in humans and were significantly associated with increased CD11b+ monocytic cellular recruitment and extent of granulomatous disease. These findings suggest a novel fractalkine-dependent ESX1-mediated mechanism in early tuberculous disease pathogenesis in humans. Modulation of M. tuberculosis-mediated fractalkine induction may represent a potential ...
Human cytomegalovirus (HCMV)-encoded G protein-coupled-receptor US28 is believed to participate in virus dissemination through modulation of cell migration and immune evasion. US28 binds different CC chemokines and the CX3C chemokine CX3CL1. Membrane-anchored CX3CL1 is expressed by immune-activated endothelial cells, causing redirection of CX3CR1-expressing leukocytes in the blood to sites of infection. Here, we used stable transfected cell lines to examine how US28 expression affects cell migration on immobilized full-length CX3CL1, to model how HCMV-infected leukocytes interact with inflamed endothelium. We observed that US28-expressing cells migrated more than CX3CR1-expressing cells when adhering to immobilized CX3CL1. US28-induced migration was G protein-signalling dependent and was blocked by the phospholipase Cβ inhibitor U73122 and the intracellular calcium chelator BAPTA-AM. In addition, migration was inhibited in a dose-dependent manner by competition from CCL2 and CCL5, whereas CCL3 ...
As a consequence of aging, the brain is subject to chronic neuroinflammatory conditions. The resident immune cells of the brain, microglia, act similarly to peripheral macrophages to protect the brain from insults, infection, and physical trauma. However, without proper regulation of their respective host defense mechanisms, these actions can become neurotoxic. In the healthy brain neurons have several signaling systems that directly interact with microglia in order to maintain a calming influence upon their actions, one of particular interest is the chemokine CX3CL1. This chemokine is found predominantly on neurons, while its cognate receptor CX3CR1 is found exclusively on microglia. There has been a recent surge in literature as to the exact role CX3CL1 signaling plays various physiological and neuropathological animal models, with still no well-defined role. In an attempt to address the current discordance regarding the role of CX3CL1 signaling we have used three different models. The first examines
Surveillant parenchymal microglial cells are extremely plastic and provide the first line of defense within the CNS. Resident microglial cells are morphologically and functionally distinct from other mononuclear CNS populations, such as perivascular macrophages, supraependymal macrophages, epiplexus cells of the choroids plexus, and meningeal macrophages (24, 25). In the naive brain, microglia display small cell bodies with thin, long, and branched processes (1). Although microglial functions are intended to be protective, it is documented that dysregulated microglial responses lead to neurotoxicity in vitro and in vivo (12). Recent data have clearly shown that activation of microglia might be beneficial in some pathological settings. More specifically, absence of CX3CR1 in two different models of Alzheimers disease correlated to reduced β-amyloid deposition because of enhanced phagocytosis by activated microglia (26, 27). Upon activation, because of inflammation of neuronal damage, microglial ...
Induction and maintenance of tumor-protective immunity are the major goals of neuroblastoma immunotherapy. Enhancing the amount of tumor infiltrating leukocytes might be a way to achieve these goals since they may be associated with residual evidence of the ineffective immune response. Fractalkine is a unique TH1 CX3C chemokine known to induce both adhesion and migration of leukocytes mediated by a membrane-bound and a soluble form, respectively. Targeted IL-2 (ch14.18-IL-2) was constructed by anti-GD2 antibody fused with IL-2 so that IL-2 can be directed into the microenvironment of neuroblastoma tumor. Here, I tested the hypothesis that chemokine gene therapy with fractalkine (FKN) induces an effective anti-neuroblastoma immune response amplified by targeted IL-2. NXS2 cells were engineered to stably produce murine FKN (NXS2-FKN). Transcrip- tion and expression of the mFKN gene in NXS2-FKN cells and tumor tissue were demonstrated. The chemotactic activity of FKN expressed by NXS2 cells was ...
|p|CX3CL1 is the unique member of the CX3C chemokine subfamily. The membrane-anchored protein, which is primarily expressed on the inflamed endothelium, serves as an adhesion protein promoting the retention of monocytes and T cells in inflamed tissue. The soluble form resembles more a conventional chemokine and strongly induces chemotaxis. Both chemotaxis and adhesion are mediated by the G protein-coupled receptor CX3CR1. CX3CL1 has been thought to play an important role in inflammation, and indeed, accumulating evidence indicates that CX3CL1/CX3CR1 are involved in the pathogenesis of various inflammatory disorders such as glomerulonephritis, rheumatoid arthritis and systemic lupus erythematosus (SLE).|/p|

Results There were no significant differences were observed in the mean age, gender ratio, dosages of predonisolone and methotraxate between ADA and TCZ groups. In ADA group, baseline DAS28 for the 15 patients was 4.8±0.3 (2.5-7.2). On the other hands, baseline DAS28 for the 20 patients was 4.8±0.3 (2.5-6.8) in TCZ group. There were no differences between ADA and TCZ groups. RA patients with an insufficient response to ADA or TCZ showed highly significant improvement of DAS28 after 12 weeks (2.9±0.3 and 2.2±0.4, respectively), and 24 weeks (2.5±0.4 to 2.2±0.2, respectively). ADAM-10 highly correlates with CDAI, and fractalkine/CX3CL1. Serum ADAM-10 levels were no remarkable change after treatment with ADA despite decrease of disease activity of RA. On the other hand, serum ADAM-10 levels in patients who were treated with TCZ were significantly diminished following successful treatment and clinical improvement (baseline 408±88 pg/ml and 54 weeks 138±51 pg/ml, p,0.05).

Purpose: Inflammation plays a substantial role in the development of diabetic retinopathy (DR). Fenofibrate, a lipid reducing drug is known to decrease inflammation and improve insulin sensitivity, and reduce the risk of DR. We aim to determine the effectiveness of fenofibrate in the treatment of diabetes by detecting the levels of downstream inflammatory mediators (IM) in hyperglycemic mice retina.. Methods: Wild type mice were fed with high fat diet (HFD), HFD with fenofibrate (30mg/kg) and normal diet for 10 weeks. Akita (Ins2Akita) mice received a dose of 50mg/kg fenofibrate and saline weekly via oral medication for 10 weeks (n=20 mice per group). Pre and post-treatment blood glucose level (BGL) measurements and retinal assessments were conducted weekly. To determine the effectiveness of fenofibrate, 11 IM levels, namely atrial natriuretic peptide (ANP), Fractalkine (CX3CR1), ICAM-1, interleukin-1 beta (IL-1β), interleukin-6 (IL-6), MCP-1, NADPH oxidase 2 (NOX2), NADPH oxidase 4 (NOX4), ...

Microglia are phagocytic cells that infiltrate the brain during development and have a role in the elimination of synapses during brain maturation. Changes in microglial morphology and gene expression have been associated with neurodevelopmental disorders. However, it remains unknown whether these changes are a primary cause or a secondary consequence of neuronal deficits. Here we tested whether a primary deficit in microglia was sufficient to induce some autism-related behavioral and functional connectivity deficits. Mice lacking the chemokine receptor Cx3cr1 exhibit a transient reduction of microglia during the early postnatal period and a consequent deficit in synaptic pruning. We show that deficient synaptic pruning is associated with weak synaptic transmission, decreased functional brain connectivity, deficits in social interaction and increased repetitive-behavior phenotypes that have been previously associated with autism and other neurodevelopmental and neuropsychiatric disorders. These ...

Figure: Induction of proinflammatory cytokines is attenuated in CX3CL1−/− mice expressing sFKN. TNFα and IL-1β concentrations were measured using standard ELISA techniques for VM lysates. a, TNFα concentrations were upregulated following MPTP administration (three-way ANOVA; F(1, 23) = 18.36, ★★★p , 0.001). Comparatively, CX3CL1−/− mice expressing sFKN in the SNpc had significantly lower concentrations of TNFα relative to mFKN (Tukeys HSD; ***p , 0.001) and GFP (Tukeys HSD; ###p , 0.001) expressing mice. There were no significant differences between sFKN and WT-MPTP (Tukeys HSD; p = 0.384) or mFKN and GFP (Tukeys HSD; p = 0.773). b, The IL-1β concentrations in the VM were significantly upregulated for mice exposed to MPTP (three-way ANOVA; F(1, 23) = 11.97, ★★★p = 0.002).

Results] Tau binding to CX3CR1 triggers the internalization of the former by microglia, whereas S396 Tau phosphorylation decreases the binding affinity of this protein to CX3CR1. Of note, the progressive increase in the levels of phosho-Tau occurred in parallel with an increase in CX3CR1. In addition, our studies suggest that the phagocytic capacity of microglia in brain tissue samples from AD patients is decreased. Furthermore, the CX3CR1/CX3CL1 axis may be impaired in late stages of the disease ...

abstract = "Connexin 43 (Cx43), a gap junction protein seemingly fit to support cardiac impulse propagation and synchronic contraction, is phosphorylated in normoxia by casein kinase 1 (CK1). However, during cardiac ischemia or pressure overload hypertrophy, this phosphorylation fades, Cx43 abundance decreases at intercalated disks and increases at myocytes lateral borders, and the risk of arrhythmia rises. Studies in wild-type and transgenic mice indicate that enhanced CK1-phosphorylation of Cx43 protects from arrhythmia, while dephosphorylation precedes arrhythmia vulnerability. The mechanistic bases of these Cx43 (de)phosphoform-linked cardiac phenotypes are unknown. We used patch-clamp and dye injection techniques to study the channel function (gating, permeability) of Cx43 mutants wherein CK1-targeted serines were replaced by aspartate (Cx43-CK1-D) or alanine (Cx43-CK1-A) to emulate phosphorylation and dephosphorylation, respectively. Cx43-CK1-D, but not Cx43-CK1-A, displayed high ...

Author(s): Koji Ohnishi Subject(s): CX.18, CX.14, CX.13, CX.67, CX.66, CX.30, CX.07 Category: Article Abstract:. Well-made biomachines such as animal body, bee society (= bee super-organism), and genetic apparatus seem to have emerged by hierarchical sociogenesis of lower-level individuals (Hamilton, 1964 ; Ohnishi et al., 1999). Bee eusociety and animal body are altruistic society consisting of fertile queens ( queen bee, germ line unicell organisms ) and workers (worker bee, somatic line unicell organisms). In the emergence of protein-synthesizing/genetic machine, early RNA replicator ribo-organisms (ROs) would have had a life cycle consisting of tRNA-phase and tDNA-phase. Such early tRNA ROs would have associated together to make a society in which some tRNAs would co-operatively behave to other tRNAs, and have begun to generate woker-like (wl-) tRNAs which are earliest mRNA/mDNAs and rRNA/rDNAs (poly-tRNA theory, Ohnishi et al., 1993, 1999). The original-type tRNA remained as queen-like ...

Human Cytomegalovirus (HCMV) is a ubiquitous human pathogen that is associated with the development of numerous inflammatory diseases including vascular disease in solid allografts and certain forms of cancer. HCMV establishes life-long persistent/latent infections via nuanced manipulation of the host immune response. As such. HCMV encodes both chemokines and chemokine receptor homologs and is able to subvert the host chemokine-signaling network in infected cells and tissues. The pathological consequences of CMV chemokine mimicry are only beginning to be understood. In this dissertation, we investigate signaling from the HCMV-encoded chemokine receptor US28 in multiple HCMV susceptible cell types and identify a novel CMV-encoded chemokine. In Chapter 2, we demonstrate that US28 is a functionally selective chemokine receptor. Binding of CC-chemokines is pro-migratory when US28 is expressed in SMC and Fractalkine is an anti-migratory stimulus to SMC. Conversely, Fractaline stimulus is chemotactic to US28

... s are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte.[1] They are protein mediators typically produced by T cells to direct the immune system response by signaling between its cells. Lymphokines have many roles, including the attraction of other immune cells, including macrophages and other lymphocytes, to an infected site and their subsequent activation to prepare them to mount an immune response. Circulating lymphocytes can detect a very small concentration of lymphokine and then move up the concentration gradient towards where the immune response is required. Lymphokines aid B cells to produce antibodies. Important lymphokines secreted by the T helper cell include:[2] ...
... binds to the death receptors DR4 (TRAIL-RI) and DR5 (TRAIL-RII). The process of apoptosis is caspase-8-dependent. Caspase-8 activates downstream effector caspases including procaspase-3, -6, and -7, leading to activation of specific kinases.[11] TRAIL also binds the receptors DcR1 and DcR2, which do not contain a cytoplasmic domain (DcR1) or contain a truncated death domain (DcR2). DcR1 functions as a TRAIL-neutralizing decoy-receptor. The cytoplasmic domain of DcR2 is functional and activates NFkappaB. In cells expressing DcR2, TRAIL binding therefore activates NFkappaB, leading to transcription of genes known to antagonize the death signaling pathway and/or to promote inflammation. Application of engineered ligands that have variable affinity for different death (DR4 and DR5) and decoy receptors (DCR1 and DCR2) may allow selective targeting of cancer cells by controlling activation of Type 1/Type 2 pathways of cell death and single cell fluctuations. Luminescent iridium complex-peptide ...
... (IL-24) is a protein that in humans is encoded by the IL24 gene. IL-24 is a cytokine belonging to the IL-10 family of cytokines that signals through two heterodimeric receptors: IL-20R1/IL-20R2 and IL-22R1/IL-20R2. This interleukin is also known as melanoma differentiation-associated 7 (mda-7) due to its discovery as a tumour suppressing protein. IL-24 appears to control in cell survival and proliferation by inducing rapid activation of particular transcription factors called STAT1 and STAT3. This cytokine is predominantly released by activated monocytes, macrophages and T helper 2 (Th2) cells[5] and acts on non-haematopoietic tissues such as skin, lung and reproductive tissues. IL-24 performs important roles in wound healing, arthritis, psoriasis and cancer.[6][7][8] Several studies have shown that cell death occurs in cancer cells/cell lines following exposure to IL-24.[9][10] The gene for IL-24 is located on chromosome 1 in humans.[11] ...

... is sometimes used interchangeably among scientists with the term cytokine.[3] Historically, cytokines were associated with hematopoietic (blood and lymph forming) cells and immune system cells (e.g., lymphocytes and tissue cells from spleen, thymus, and lymph nodes). For the circulatory system and bone marrow in which cells can occur in a liquid suspension and not bound up in solid tissue, it makes sense for them to communicate by soluble, circulating protein molecules. However, as different lines of research converged, it became clear that some of the same signaling proteins which the hematopoietic and immune systems use were also being used by all sorts of other cells and tissues, during development and in the mature organism. While growth factor implies a positive effect on cell division, cytokine is a neutral term with respect to whether a molecule affects proliferation. While some cytokines can be growth factors, such as G-CSF and GM-CSF, others have an inhibitory effect on ...

The protein encoded by this gene is a member of the interleukin 1 cytokine family. Protein structure modeling indicated that this cytokine may contain a 12-stranded beta-trefoil structure that is conserved between IL1A (IL-A alpha) and IL1B (IL-1 beta). This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. Two alternatively spliced transcript variants encoding distinct isoforms have been reported.[8]. ...
