Abstract
Recent evidence supporting that adipose tissue (AT)-derived extracellular vesicles (EVs) carry an important part of the AT secretome led us to characterize the EV-adipokine profile. In addition to evidencing a high AT-derived EV secretion ability that is further increased by obesity, we identify enrichment of oligomeric forms of adiponectin in small EVs (sEVs). This adipokine is mainly distributed at the EV external surface as a result of nonspecific adsorption of soluble adiponectin. EVs also constitute stable conveyors of adiponectin in the blood circulation. Adiponectin-enriched sEVs display in vitro insulin-sensitizing effects by binding to regular adiponectin receptors. Adoptive transfer of adiponectin-enriched sEVs in high-fat-diet-fed mice prevents animals from gaining weight and ameliorated insulin resistance and tissue inflammation, with major effects observed in the AT and liver. Our results therefore provide information regarding adiponectin-related metabolic responses by highlighting EVs as delivery platforms of metabolically active forms of adiponectin molecules.

Abstract
Adipose extracellular vesicles (AdEVs) transport lipids that could participate in the development of obesity-related metabolic dysfunctions. This study aims to define mouse AdEV lipid signature by a targeted LC-MS/MS approach in either healthy or obesity context. Distinct clustering of AdEV and visceral adipose tissue (VAT) lipidomes by principal component analysis reveals specific AdEV lipid sorting when compared with secreting VAT. Comprehensive analysis identifies enrichment of ceramides, sphingomyelins, and phosphatidylglycerols species in AdEVs compared with source VAT whose lipid content closely relates to the obesity status and is influenced by the diet. Obesity moreover impacts AdEV lipidome, mirroring lipid alterations retrieved in plasma and VAT. Overall, our study identifies specific lipid fingerprints for plasma, VAT, and AdEVs that are informative of the metabolic status. Lipid species enriched in AdEVs in the obesity context may constitute biomarker candidates or mediators of the obesity-associated metabolic dysfunctions.

Abstract
Pathological gait assessment and assistive control based on functional electrical stimulation (FES) in post-stroke individuals, brings out a common need to robustly quantify kinematics facing multiple constraints. This study proposes a novel approach using inertial sensors to compute dorsiflexion angles and spatio-temporal parameters, in order to be later used as inputs for online close-loop control of FES. 26 post-stroke subjects were asked to walk on a pressure mat equipped with inertial measurement units (IMU) and passive reflective markers. A total of 930 strides were individually analyzed and results between IMU-based algorithms and reference systems compared. Mean absolute (MA) errors of dorsiflexion angles were found to be less than 4°, while stride lengths were robustly segmented and estimated with a MA error less than 10 cm. These results open new doors to rehabilitation using adaptive FES closed-loop control strategies in "foot drop" syndrome correction.

Abstract
Background After a stroke, during seated reaching with their paretic upper limb, many patients spontaneously replace the use of their arm by trunk compensation movements, even though they are able to use their arm when forced to do so. We previously quantified this proximal arm non-use (PANU) with a motion capture system (Zebris, CMS20s). The aim of this study was to validate a low-cost Microsoft Kinect-based system against the CMS20s reference system to diagnose PANU. Methods In 19 hemiparetic stroke individuals, the PANU score, reach length, trunk length, and proximal arm use (PAU) were measured during seated reaching simultaneously by the Kinect (v2) and the CMS20s over two testing sessions separated by two hours. Results Intraclass correlation coefficients (ICC) and linear regression analysis showed that the PANU score (ICC = 0.96, r2 = 0.92), reach length (ICC = 0.81, r2 = 0.68), trunk length (ICC = 0.97, r2 = 0.94) and PAU (ICC = 0.97, r2 = 0.94) measured using the Kinect were strongly related to those measured using the CMS20s. The PANU scores showed good test-retest reliability for both the Kinect (ICC = 0.76) and CMS20s (ICC = 0.72). Bland and Altman plots showed slightly reduced PANU scores in the re-test session for both systems (Kinect: − 4.25 ± 6.76; CMS20s: − 4.71 ± 7.88), which suggests a practice effect. Conclusion We showed that the Kinect could accurately and reliably assess PANU, reach length, trunk length and PAU during seated reaching in post stroke individuals. We conclude that the Kinect can offer a low-cost and widely available solution to clinically assess PANU for individualised rehabilitation and to monitor the progress of paretic arm recovery. Trial registration The study was approved by The Ethics Committee of Montpellier, France (N°ID-RCB: 2014-A00395–42) and registered in Clinical Trial (N° NCT02326688, Registered on 15 December 2014, https://clinicaltrials.gov/ct2/show/results/NCT02326688).

Abstract
Innovative technologies for sensorimotor rehabilitation after stroke have dramatically increased these past 20 years. Based on a review of the literature on "Medline" and "Web of Science" between 1990 and 2013, we offer an overview of available tools and their current level of validation. Neuromuscular electric stimulation and/or functional electric stimulation are widely used and highly suspected of being effective in upper or lower limb stroke rehabilitation. Robotic rehabilitation has yielded various results in the literature. It seems to have some effect on functional capacities when used for the upper limb. Its effectiveness in gait training is more controversial. Virtual reality is widely used in the rehabilitation of cognitive and motor impairments, as well as posture, with admitted benefits. Non-invasive brain stimulation (rTMS and TDCS) are promising in this indication but clinical evidence of their effectiveness is still lacking. In the same manner, these past five years, neurofeedback techniques based on brain signal recordings have emerged with a special focus on their therapeutic relevance in rehabilitation. Technological devices applied to rehabilitation are revolutionizing our clinical practices. Most of them are based on advances in neurosciences allowing us to better understand the phenomenon of brain plasticity, which underlies the effectiveness of rehabilitation. The acceptation and "real use" of those devices is still an issue since most of them are not easily available in current practice.

Abstract
Interleukin-31 (IL-31) is a recently described T cell-derived cytokine, mainly produced by T helper type 2 cells and related to the IL-6 cytokine family according to its structure and receptor. IL-31 is the ligand for a heterodimeric receptor composed of a gp130-like receptor (GPL) associated with the oncostatin M receptor (OSMR). A link between IL-31 and atopic dermatitis was shown by studying the phenotype of IL-31 transgenic mice and IL-31 gene haplotypes in patients suffering from dermatitis. In this study, we generated a potent IL-31 antagonist formed by external portions of OSMR and GPL fused with a linker. This fusion protein, OSMR-L-GPL, consisting of 720 amino acids, counteracted the binding of IL-31 to its membrane receptor complex and the subsequent signaling events involving the STATs and MAPK pathways. Neutralizing effects were found in IL-31-sensitive cell lines, including brain-derived cells and primary cultures of keratinocytes.

Abstract
Interleukin (IL)-31 is a recently described cytokine, preferentially produced by T helper 2 lymphocytes and associated with skin diseases, such as atopic dermatitis. IL-31 is a member of the four alpha-helix bundle cytokine family and is related to the IL-6 subgroup. Its heterodimeric membrane receptor is composed of the gp130-like receptor (GPL) subunit associated to the oncostatin M receptor subunit. We identified critical amino acids implicated in the ligand receptor interaction by computational analysis combined with site-directed mutagenesis. Six IL-31 residues selected for their putative involvement in cytokine receptor contact sites were alanine-substituted, and the corresponding proteins were expressed in mammalian and bacterial systems. Biochemical, membrane binding, cell signaling, and cell proliferation analyses showed that mutation E44A, E106A, or H110A abolished IL-31 binding to GPL and the subsequent signaling events. A second ligand receptor-binding site involved Lys(134), with alanine substitution leading to a protein that still binds GPL, but is unable to recruit the second receptor subunit and the subsequent signaling pathways. The results indicate that IL-31 recognizes its receptor complex through two different binding sites, and we propose a three-dimensional model for IL-31.

Abstract
Ciliary neurotrophic factor, cardiotrophin-like cytokine, and neuropoietin are members of the four-helix bundle cytokine family. These proteins signal through a common tripartite receptor composed of leukemia inhibitory factor receptor, gp130, and ciliary neurotrophic factor receptor alpha. Binding to ciliary neurotrophic factor receptor alpha occurs through an interaction site located at the C terminus of the cytokine AB loop and alphaD helix, known as site 1. In the present study, we have generated a model of neuropoietin and identified a conserved binding site for the three cytokines interacting with ciliary neurotrophic factor receptor alpha. To identify the counterpart of this site on ciliary neurotrophic factor receptor alpha, its cytokine binding domain was modeled, and the physicochemical properties of its surface were analyzed. This analysis revealed an area displaying properties complementary to the site 1 of ciliary neurotrophic factor, cardiotrophin-like cytokine, and neuropoietin. Based on our computational predictions, residues were selected for their potential involvement in the ciliary neurotrophic factor receptor alpha binding epitope, and site-directed mutagenesis was carried out. Biochemical, cell proliferation, and cell signaling analyses showed that Phe(172) and Glu(286) of ciliary neurotrophic factor receptor alpha are key interaction residues. Our results demonstrated that ciliary neurotrophic factor, cardiotrophin-like cytokine, and neuropoietin share a conserved binding site on ciliary neurotrophic factor receptor alpha.

Abstract
Cutaneous inflammatory diseases such as psoriasis vulgaris and atopic dermatitis are associated with altered keratinocyte function, as well as with a particular cytokine production profile of skin-infiltrating T lymphocytes. In this study we show that normal human epidermal keratinocytes express a functional type II oncostatin-M (OSM) receptor (OSMR) consisting of the gp130 and OSMRbeta components, but not the type I OSMR. The type II OSMR is expressed in skin lesions from both psoriatic patients and those with atopic dermatitis. Its ligand, OSM, induces via the recruitment of the STAT3 and MAP kinase pathways a gene expression profile in primary keratinocytes and in a reconstituted epidermis that is characteristic of proinflammatory and innate immune responses. Moreover, OSM is a potent stimulator of keratinocyte migration in vitro and increases the thickness of a reconstituted epidermis. OSM transcripts are enhanced in both psoriatic and atopic dermatitic skin as compared with healthy skin and mirror the enhanced production of OSM by T cells isolated from diseased lesions. Results from a microarray analysis comparing the gene-modulating effects of OSM with those of 33 different cytokines indicate that OSM is a potent keratinocyte activator similar to TNF-alpha, IL-1, IL-17, and IL-22 and that it acts in synergy with the latter cytokines in the induction of S100A7 and beta-defensin 2 expression, characteristic of psoriatic skin. Taken together, these results demonstrate that OSM and its receptor play an important role in cutaneous inflammatory responses in general and that the specific effects of OSM are associated with distinct inflammatory diseases depending on the cytokine environment.

Abstract
INTRODUCTION Bickerstaff brainstem encephalitis is characterized by the occurrence of ataxia, ophthalmoplegia, motor weakness with areflexia and central nervous system symptoms, with drowsiness, pyramidal syndrome and sensorial symptoms. Diagnosis is based on MR findings and GQ1b antibodies. Treatment is not well known. OBSERVATION We report a patient aged 39 years native of Laos who presented weakness, loss of reflexes, and drowsiness. Brain MR showed hyperintense signals in the brain stem. GQ1b antibodies were positive. The course was characterized by decrease of the weakness, normalization of MR and negativity of GQ1b antibodies. DISCUSSION This observation underlines common features of Bickerstaff brainstem encephalitis, Miller Fisher syndrome and Guillain Barre syndrome. A favorable course and GQ1b antibodies are shared by these syndromes.

Abstract
INTRODUCTION Rate of relapse occurring during the first 5 years of MS-RR is a prognosis factor of occurrence of disability or secondary progressive (SP) phase. Progressive phase, related to chronic axonal loss, is mainly considered as the principal factor of disability progression. Influence of acute relapses during the relapsing-remitting phase on disability development is not known as a prognosis factor. OBJECTIVES To determine the influence of the exacerbations among patients with RR-MS after the second clinical event on the disability occurrence. METHODS Diagnosis of multiple sclerosis was established according to Poser's classification. Disability measurement was made with the use of the Expanded Disability Status Scale (EDSS). The patients included in the study were classified as clinically definite RR-MS, with an EDSS score<or=3.5. The progressive phase was defined as the steady worsening of symptoms and signs for at least 6 months (Schumacher et al., 1965; Lublin and Reingold, 1996). The exacerbations were quoted and evaluated by a neurologist and the residual disability lasting at least 6 months after an acute event was measured with the EDSS. A score of 4.0 corresponds to limited walking ability, but without aid or rest for>500 m. The study began at the time of the second clinical event and ended when an EDSS score of 4.0 was reached or when a SP phase was beginning or at the last follow-up visit date if these two stages were not reached. The primary outcome measure was the comparison of the risk and the average time to reach an EDSS>or=4.0 or a SP form according to the annual exacerbation rate (AER) using Kaplan-Meier survival curve. RESULTS Among the 238 ms patients of the database, 136 patients were classified as having a definite RR-MS. Among these 136 patients, 99 patients could be included in the study according to the inclusion criteria. The median follow up of the patients since the first clinical event was 9.8 years (range 4 to 44). The average EDSS score was 0.7 at the beginning of the study and 2.3 at the end. 20.2p.cent of patients (n=20) reached an EDSS score of 4.0 or a SP-MS. The median AER was 0.4 and the average 0.62 (range 0 to 6.1). The time to reach the primary end point for 25p.cent of the population was 17.8 years in group with an AER<0.4 (group A) and 6.9 years in group with an AER>0.4 (group B) (logrank; p<0.0001). The relative risk for patients of the group B compared to group A to reach an EDSS of 4.0 or a SP form was 8.01 (IC-95p.cent: 2.74-23.46; p=0.0001). CONCLUSIONS In spite of a limited number of patients, this study gives evidence that a high rate of acute exacerbations in RR-MS patients after the second clinical event may be an independent predictive factor of long-term residual disability progression. High relapse rate leads to a more frequent and faster SP or EDSS>4.0 occurrence.

Abstract
Activation of the signaling transduction pathways mediated by oncostatin M (OSM) requires the binding of the cytokine to either type I OSM receptor (leukemia inhibitory factor receptor/gp130) or to type II OSM receptor (OSMR/gp130). In the present work we have developed an enzyme-linked immunosorbent assay detecting a soluble form of OSMR (sOSMR) secreted by glioblastoma, hepatoma, and melanoma tumor cell lines. sOSMR was also present in sera of healthy individuals, with increased levels in multiple myeloma. Molecular cloning of a corresponding cDNA was carried out, and it encoded for a 70-kDa protein consisting of a half cytokine binding domain containing the canonical WSXWS motif, an immunoglobulin-like domain, and the first half of a second cytokine binding domain with cysteines in fixed positions. Analysis of the soluble receptor distribution revealed a preferential expression in lung, liver, pancreas, and placenta. sOSMR was able to bind OSM and interleukin-31 when associated to soluble gp130 or soluble interleukin-31R, respectively, and to neutralize both cytokine properties. We have also shown that OSM could positively regulate the synthesis of its own soluble receptor in tumor cells.

Abstract
Ciliary neurotrophic factor (CNTF) receptor controls a pathway supporting the differentiation and survival of a wide range of neural cell types during development and in adulthood. Cardiotrophin-like cytokine (CLC)-cytokine-like factor 1 (CLF) composite cytokine is a second ligand for the CNTF alpha-component receptor (CNTFRalpha). This composite cytokine is built on the structural model of IL-12, with a complex formed by a four-helix bundle type I cytokine, CLC (also referred to as CLCF1), bound to a soluble receptor subunit, CLF (also known as CRLF1). We have reported mutations in the chaperone soluble receptor CLF, causing cold-induced sweating syndrome (CISS). In this study, we studied the CLC-mutated alleles in a patient suffering from a similar disease. This patient was compound heterozygous for two different CLC mutations. The first allele was inactivated by a stop codon at position 107 (Y107X). In the second allele, a R197L mutation in the CLC-predicted binding site to the CNTFRalpha was detected. Functional analysis of the mutated protein revealed an incapacity for R197L CLC to bind to CNTFRalpha and activate the subsequent signaling events. Structural and docking interaction studies showed that the R197L substitution destabilized the contact site between CLC and CNTFRalpha.

Abstract
IL-27 is a novel heterodimeric cytokine of the IL-12 family that plays an important role in the regulation of T cell responses. Its role on human B cells has not been previously studied. In this study, we show that both chains of the IL-27 receptor complex, IL-27R and gp130, are constitutively expressed at the surface of naive and memory human tonsillar B cells, and are induced on germinal center B cells following CD40 stimulation. In naive B cells, IL-27 induced strong STAT1 and STAT3 phosphorylation, whereas it induced moderate STAT1 and low STAT3 activation in memory B cells. IL-27 induced T-bet expression in naive and memory B cells stimulated by CD40 or surface Ig engagement, but induced significant IL-12Rbeta2 surface expression in anti-Ig-stimulated naive B cells only. In anti-Ig-stimulated naive or memory B cells, IL-27 also induced CD54, CD86, and CD95 surface expression. In addition, IL-27 increased proliferation of anti-Ig-activated naive B cells and of anti-CD40-activated naive and germinal center B cells, but not of CD40-activated memory B cells. These data indicate that the B cell response to IL-27 is modulated during B cell differentiation and varies depending on the mode of B cell activation.

Abstract
The assessment of autonomy in elderly people relies on various instruments that aim to evaluate and follow up patients, to measure the burden of care for the medical staff, or to properly distribute health budgets. In this article, we describe 3 clinical scales traditionally employed by gerontologists and specialists in geriatric rehabilitation. We intentionally left out generic scales such as the Barthel index and the Functional Independence Measure, which are well known by physiatrists. The Katz index is a scale of Activities of Daily Living, and the Lawton test is a scale of Instrumental Activities of Daily Living. We paid special attention to the AGGIR classification, which is the actual legal instrument for evaluating dependency in elderly in France, and whose first application is health resources management.

Abstract
The cytokines of the interleukin-6 family are multifunctional proteins that regulate cell growth, differentiation, and other cell functions in a variety of biological systems including the immune, inflammatory, hematopoietic, and nervous systems. One member of this family, ciliary neurotrophic factor (CNTF), displays biological functions more restricted to the neuromuscular axis. We have recently identified two additional ligands for the CNTF receptor complex. Both are composite cytokines formed by cardiotrophin-like cytokine (CLC) associated to either the soluble type I cytokine receptor CLF or the soluble form of CNTF receptor alpha (CNTFRalpha). The present study was aimed at analyzing the interactions between the cytokine CLC and its different receptor chains. For this purpose, we modeled CLC/receptor interactions to define the residues potentially involved in the contact sites. We then performed site-directed mutagenesis on these residues and analyzed the biological interactions between mutants and receptor chains. Importantly, we found that CLC interacts with the soluble forms of CNTFRalpha and CLF via sites 1 and 3, respectively. For site 1, the most crucial residues involved in the interaction are Trp67, Arg170, and Asp174, which interact with CNTFRalpha. Surprisingly, the residues that are important for the interaction of CLC with CLF are part of the conserved FXXK motif of site 3 known to be the interaction site of LIFRbeta. Obtained results show that the Phe151 and Lys154 residues are effectively involved in the interaction of CLC with LIFRbeta. This study establishes the molecular details of the interaction of CLC with CLF, CNTFRalpha, and LIFRbeta and helps to define the precise role of each protein in this functional receptor complex.

Abstract
Gp130-like receptor (GPL) is a newly identified cytokine receptor. A recent study reported the involvement of GPL, together with OSMR, in the formation of the receptor complex for IL-31, a novel immune cytokine with a skin tropism. In the present work, we analyzed the signaling properties of IL-31 in glioblastoma and melanoma tumor cells. We demonstrate that in response to IL-31, its receptor complex recruits Jak1, Jak2, STAT1, -3, -5 signaling pathways, as well as the Pi3 kinase / AKT cascade. SHP-2 and Shc adapter molecules are also recruited and contribute to an increased activation of the MAP kinase pathway in response to IL-31. Different responses were observed depending on the expression of short or long GPL receptor isoform within the studied cell lines. We show that the short form of GPL receptor exerts a profound inhibitory effect on the signaling of IL-31 and behaves as a dominant negative receptor.

Abstract
A structural profile-based computational screen was used to identify neuropoietin (NP), a new cytokine. The np gene is localized in tandem with the cardiotrophin-1 gene on mouse chromosome 7. NP shares structural and functional features with ciliary neurotrophic factor (CNTF), cardiotrophin-1, and cardiotrophin-like cytokine. It acts through a membrane receptor complex comprising CNTF receptor-alpha component (CNTFRalpha), gp130, and leukemia inhibitory factor receptor to activate signal transducer and activator of transcription 3 signaling pathway. NP is highly expressed in embryonic neuroepithelia. Strikingly, CNTFRalpha, but not its alternate ligands, CNTF and cardiotrophin-like cytokine, is expressed at the same developmental stages. NP is also observed in retina and to a lesser extent in skeletal muscle. Moreover, NP could sustain the in vitro survival of embryonic motor neurons and could increase the proliferation of neural precursors when associated to epidermal growth factor and fibroblast growth factor 2. Thus, NP is a new ligand for CNTFRalpha, with important implications for murine nervous system development.

Abstract
We describe a novel cytokine receptor named GP130 Like receptor, or GPL, that displays similarities with the interleukin-6 and interleukin-12 family of signaling receptors. Four different isoforms diverging in their carboxyl terminus were isolated, corresponding to proteins encompassing 560, 610, 626, and 745 amino acids. Sequences included a signal peptide of 32 amino acids, followed by a cytokine binding domain containing four conserved cysteines, a WSDWS motif, and a region consisting of three fibronectin type III domain repeats. No immunoglobulin-like module was identified in the GPL sequences. The intracellular part of longer isoforms contained a proline-rich region defining a box1 motif for interaction with the Janus kinases. The Gpl gene is organized in 15 exons and is located on 5q11.2 in tandem with the gp130 gene. Both genes were only separated by 24 kilobases, with opposite transcriptional orientations. The GPL receptor displayed a 28% identity with gp130. Specific GPL transcripts were observed in tissues involved in reproduction. Transcripts were also found in blood cells and in bone marrow, revealing expression of GPL in all of the myelomonocytic lineage, from hematopoietic stem cells to activated dendritic cells. In monocytes and dendritic cells, expression of GPL was strongly up-regulated by interferon-gamma, indicating a possible involvement of GPL in Th1-type immune responses. The molecular basis of cell signaling mediated by GPL was studied using chimeric receptors where external portions of alpha or beta interleukin-5 receptor subunits were fused to the internal portion of GPL or of related receptors. Results indicated that association of GPL to the intracellular portions of gp130, or LIF receptor, allowed the signaling cascade.

Abstract
Leukemia inhibitory factor (LIF), cardiotrophin-1 (CT-1), and oncostatin M (OSM) are four helix bundle cytokines acting through a common heterodimeric receptor composed of gp130 and LIF receptor (LIFR). Binding to LIFR occurs through a binding site characterized by an FXXK motif located at the N terminus of helix D (site III). The immunoglobulin (Ig)-like domain of LIFR was modeled, and the physico-chemical properties of its Connolly surface were analyzed. This analysis revealed an area displaying properties complementary to those of the LIF site III. Two residues of the Ig-like domain of LIFR, Asp214 and Phe284, formed a mirror image of the FXXK motif. Engineered LIFR mutants in which either or both of these two residues were mutated to alanine were transfected in Ba/F3 cells already containing gp130. The F284A mutation impaired the biological response induced by LIF and CT-1, whereas the response to OSM remained unchanged. The Asp214 mutation did not alter the functional responses. The D214A/F284A double mutation, however, totally impaired cellular proliferation to LIF and CT-1 and partially impaired OSM-induced proliferation with a 20-fold increase in EC50. These results were corroborated by the analysis of STAT3 phosphorylation and Scatchard analysis of cytokine binding to Ba/F3 cells. Molecular modeling of the complex of LIF with the Ig-like domain of LIFR provides a clue for the superadditivity of the D214A/F284A double mutation. Our results indicate that LIF, CT-1, and OSM share an overlapping binding site located in the Ig-like domain of LIFR. The different behaviors of LIF and CT-1, on one side, and of OSM, on the other side, can be related to the different affinity of their site III for LIFR.

Abstract
Interleukin (IL)-6-type cytokines are multifunctional proteins involved in cardiac hypertrophy and myocardial protection. Recent studies, performed on animal models, report the production of these cytokines by heart. The aim of this study was to analyse the capacity of myocytes and fibroblasts isolated from human atrium to secrete IL-6, leukaemia inhibitory factor (LIF), cardiotrophin-1 (CT-1), IL-11, oncostatin M (OSM), ciliary neurotrophic factor (CNTF) and the soluble receptor subunits sIL-6R and sgp130 during primary culture. We detected LIF, IL-11, sgp130 and a large amount of IL-6, but not OSM, CT-1, CNTF nor IL-6R in these culture supernatants. Both cardiomyocytes and fibroblasts are able to spontaneously produce IL-6. The increase of IL-6 production all along the culture period appears to be the consequence of fibroblast proliferation and gp130 stimulation. This is the first demonstration that human cardiac cells are able to secrete IL-6, but also LIF and IL-11 in vitro. These cytokines could be involved in an autocrine and/or a paracrine networks regulating myocardial cyto-protection, hypertrophy and fibrosis.

Abstract
The heterodimeric cytokine composed of the soluble ciliary neurotrophic factor receptor (sCNTFR) and the IL-6 family member cardiotrophin-like cytokine (CLC) was recently identified as a new ligand for gp130-leukemia inhibitory factor receptor (LIFR) complex [Plun-Favreau, H., Elson, G., Chabbert, M., Froger, J., deLapeyriere, O., Lelievre, E., Guillet, C., Hermann, J., Gauchat, J. F., Gascan, H. & Chevalier, S. (2001) EMBO J. 20, 1692-1703]. This heterodimer shows overlapping biological properties with LIF. Although CLC contains a putative signal peptide and therefore should enter into the classical secretory pathway, the protein has been shown to be retained within transfected mammalian cells, unless coexpressed with either sCNTFR or cytokine like factor (CLF) [Elson, G.

In the present study, we demonstrate that a fusion protein comprising CLC covalently coupled through a glycine/serine linker to sCNTFR (CC-FP) is efficiently secreted from transfected mammalian cells. CC-FP shows enhanced activities in respect to the CLC/sCNTFR native complex, on a number of cells expressing gp130 and LIFR on their surface. In addition, CC-FP is able to compete with CNTF for cell binding, indicating that both cytokines share binding epitope(s) expressed by their receptor complex. Analysis of the downstream signaling events revealed the recruitment by CC-FP of the signal transducer and activator of transcription (STAT)-3, Akt and mitogen-activated protein (MAP) kinase pathways. The monomeric bioactive CLC/sCNTFR fusion protein is therefore a powerful tool to study the biological role of the recently described cytokine CLC.
