Item Wnt and RUNX2 mediate cartilage breakdown by osteoarthritis synovial fibroblast‐derived ADAMTS‐7 and ‐12(Journal of Cellular and Molecular Medicine, 2019) Pérez García, Selene; Carrión Caballo, Mar; Villanueva Romero, Raúl; Hermida Gómez, Tamara; Fernández Moreno, Mercedes; Mellado, Mario; Blanco, Francisco J.; Juarranz Moratilla, Yasmina; Gomáriz, Rosa P.Failure of therapeutic approaches for the treatment of osteoarthritis (OA) based on the inhibition of metalloproteinases, might be because of their constitutive expres‐ sion in homeostasis, together with their network complexity. The knowledge of this network would contribute to selective target pathological conditions. In this sense, blockade of mediators produced by neighbouring joint cells, such as synovial fibro‐ blasts (SF), would prevent cartilage damage. Thus, we studied the contribution of ADAMTS‐7 and ‐12 from SF to cartilage oligomeric matrix protein (COMP) degrada‐ tion, and the signalling pathways involved in their expression. We report for the first time in SF, the involvement of ERK‐Runx2 axis and Wnt/β‐catenin signalling in ADAMTS‐12 and ADAMTS‐7 expressions, respectively, with the subsequent conse‐ quences in COMP degradation from cartilage extracellular matrix. After stimulation with IL‐1β or fibronectin fragments, we showed that ERK inhibition decreased Runx2 activation and ADAMTS‐12 expression in OA‐SF, also reducing Fn‐fs‐induced COMP degradation. Blockage of Wnt signalling by DKK1 reduced ADAMTS‐7 and COMP degradation in OA‐SF as well. In addition, Wnt7B expression was induced by IL‐1β and by itself, also increasing ADAMTS‐7. Our results could contribute to the develop‐ ment of disease‐modifying OA drugs targeting ADAMTS‐7 and ‐12 for the prevention of extracellular matrix components degradation like COMP.Item Activation of Th lymphocytes alters pattern expression and cellular location of VIP receptors in healthy donors and early arthritis patients(Scientific Reports, 2019) Villanueva Romero, Raúl; Gutiérrez Cañas, Irene; Carrión Caballo, Mar; González Álvaro, Isidoro; Rodríguez Frade, José Miguel; Mellado, Mario; Martínez, Carmen; Gomáriz, Rosa P.; Juarranz Moratilla, YasminaVasoactive Intestinal Peptide (VIP) is an important immunomodulator of CD4+ cells in normal and pathological conditions, which exerts its anti-infammatory and immunomodulatory actions through VPAC receptors, VPAC1 and VPAC2. Only a decrease in the expression of VPAC1 mRNA on Th cells upon activation has been reported. Thus, the deepening in the knowledge of the behavior of these receptors may contribute to the design of new therapies based on their activation and/or blockade. In this study, we describe the expression pattern, cellular location and functional role of VIP receptors during the activation of human Th cells in healthy conditions and in early arthritis (EA). The protein expression pattern of VPAC1 did not change with the activation of Th lymphocytes, whereas VPAC2 was up-regulated. In resting cells, VPAC1 was located on the plasma membrane and nucleus, whereas it only appeared in the nucleus in activated cells. VPAC2 was always found in plasma membrane location. VIP receptors signaled through a PKA-dependent pathway in both conditions, and also by a PKAindependent pathway in activated cells. Both receptors exhibit a potent immunomodulatory capacity by controlling the pathogenic profle and the activation markers of Th cells. These results highlight a novel translational view in infammatory/autoimmune diseases.Item An Overview of VPAC Receptors in Rheumatoid Arthritis: Biological Role and Clinical Significance(Frontiers in Endocrinology, 2019) Gomáriz, Rosa P.; Juarranz Moratilla, Yasmina; Carrión Caballo, Mar; Pérez García, Selene; Villanueva Romero, Raúl; González Álvaro, Isidoro; Gutiérrez Cañas, Irene; Lamana, Amalia; Martínez, CarmenThe axis comprised by the Vasoactive Intestinal Peptide (VIP) and its G protein-coupled receptors (GPCRs), VPAC1, and VPAC2, belong to the B1 family and signal through Gs or Gq proteins. VPAC receptors seem to preferentially interact with Gs in inflammatory cells, rather than Gq, thereby stimulating adenylate cyclase activity. cAMP is able to trigger various downstream pathways, mainly the canonical PKA pathway and the non-canonical cAMP-activated guanine nucleotide exchange factor (EPAC) pathway. Classically, the presence of VPACs has been confined to the plasma membrane; however, VPAC1 location has been described in the nuclear membrane in several cell types such as activated Th cells, where they are also functional. VPAC receptor signaling modulates a number of biological processes by tipping the balance of inflammatory mediators in macrophages and other innate immune cells, modifying the expression of TLRs, and inhibiting MMPs and the expression of adhesion molecules. Receptor signaling also downregulates coagulation factors and acute-phase proteins, promotes Th2 over Th1, stimulates Treg abundance, and finally inhibits a pathogenic Th17 profile. Thus, the VIP axis signaling regulates both the innate and adaptive immune responses in several inflammatory/autoimmune diseases. Rheumatoid arthritis (RA) is a complex autoimmune disease that develops on a substrate of genetically susceptible individuals and under the influence of environmental factors, as well as epigenetic mechanisms. It is a heterogeneous disease with different pathogenic mechanisms and variable clinical forms between patients with the same diagnosis. The knowledge of VIP signaling generated in both animal models and human ex vivo studies can potentially be translated to clinical reality. Most recently, the beneficial effects of nanoparticles of VIP self-associated with sterically stabilized micelles have been reported in a murine model of RA. Another novel research area is beginning to define the receptors as biomarkers in RA, with their expression levels shown to be associated with the activity of the disease and patients-reported impairment. Therefore, VPAC expression together VIP genetic variants could allow patients to be stratified at the beginning of the disease with the purpose of guiding personalized treatment decisions.Item The anti-inflammatory mediator, vasoactive intestinal peptide, modulates the differentiation and function of Th Subsets in rheumatoid arthritis(Journal of Immunology Research, 2018) Villanueva Romero, Raúl; Gutiérrez Cañas, Irene; Carrión Caballo, Mar; Pérez García, Selene; Seoane Valiño, Iria V.; Martínez, Carmen; Gomáriz, Rosa P.; Juarranz Moratilla, YasminaGenetic background, epigenetic modifications, and environmental factors trigger autoimmune response in rheumatoid arthritis (RA). Several pathogenic infections have been related to the onset of RA and may cause an inadequate immunological tolerance towards critical self-antigens leading to chronic joint inflammation and an imbalance between different T helper (Th) subsets. Vasoactive intestinal peptide (VIP) is a mediator that modulates all the stages comprised between the arrival of pathogens and Th cell differentiation in RA through its known anti-inflammatory and immunomodulatory actions. This “neuroimmunopeptide” modulates the pathogenic activity of diverse cell subpopulations involved in RA as lymphocytes, fibroblast-like synoviocytes (FLS), or macrophages. In addition, VIP decreases the expression of pattern recognition receptor (PRR) such as toll-like receptors (TLRs) in FLS from RA patients. These receptors act as sensors of pathogen-associated molecular pattern (PAMP) and damage-associated molecular pattern (DAMP) connecting the innate and adaptive immune system. Moreover, VIP modulates the imbalance between Th subsets in RA, decreasing pathogenic Th1 and Th17 subsets and favoring Th2 or Treg profile during the differentiation/polarization of naïve or memory Th cells. Finally, VIP regulates the plasticity between theses subsets. In this review, we provide an overview of VIP effects on the aforementioned features of RA pathology.Item Inflammatory mediators alter interleukin-17 receptor, interleukin-12 and -23 expression in human osteoarthritic and rheumatoid arthritis synovial fibroblasts: Immunomodulation by vasoactive intestinal peptide(Neuroimmunomodulation, 2013) Carrión Caballo, Mar; Pérez García, Selene; Jimeno, Rebeca; Juarranz Moratilla, Yasmina; González Álvaro, Isidoro; Pablos Álvarez, José Luis; Gutiérrez Cañas, Irene; Pérez Gomáriz, Rosa MaríaAims: To assess the contribution of fibroblast-like synoviocytes (FLS) to the inflammatory joint microenvironment under different pathogenic stimuli and their potential to respond to interleukin (IL)-17 and to determine whether the neuroimmunomodulatory vasoactive intestinal peptide (VIP) is able to modulate IL-17 receptor (IL-17R) and related cytokines. Methods: The effect of proinflammatory cytokines [tumor necrosis factor (TNF) and IL-17] and Toll-like receptor (TLR) ligands [poly(I:C) and lipopolysaccharide (LPS)] on IL-17R expression and IL-12 and IL-23 production was studied in osteoarthritis (OA)- and rheumatoid arthritis (RA)-FLS, involved in Th1Th17 differentiation. The effect of VIP was also determined. IL-17RA, IL-17RC, IL-12p35 and IL-23p19 expression was measured by real-time polymerase chain reaction. IL-12 and IL-23 protein levels were measured by ELISA in supernatant cultures. Results: TNF, LPS and poly(I:C) induced an increase in IL-17RA in RA-FLS, whereas TNF, TNF plus IL-17 and poly(I:C) enhanced IL-17RC transcripts in FLS. VIP diminished the upregulated expression of IL-17RA in RA-FLS following TNF and poly(I:C). TNF, LPS and poly(I:C) increased IL-12 and IL-23 levels in cells derived from patients presenting both pathologies. However, IL-17A decreased IL-12 and augmented IL-23. VIP decreased IL-12p35 mRNA upregulation by poly(I:C) and IL-23p19 transcripts in LPS-treated FLS. Conclusions: Inflammatory cytokines and TLR ligands modulate IL-17R, IL-12 and IL-23 possibly favoring the cross talk between FLS and Th1Th17 cells. The ability of VIP to counteract the enhancing effect of proinflammatory molecules on IL-17R and the IL-12 family of cytokines corroborates and amplifies the beneficial effect of this endogenous neuroimmunopeptide in rheumatic diseases.Item Vasoactive intestinal peptide gene polymorphisms, associated with its serum levels, predict treatment requirements in early rheumatoid arthritis(Scientific Reports, 2018) Seoane Valiño, Iria V.; Martínez, Carmen; Garcia-Vicuña, Rosario; Ortiz, Ana M.; Juarranz Moratilla, Yasmina; Talayero, Vanessa C.; González-Álvaro, Isidoro; Gomáriz, Rosa P.; Lamana, AmaliaWe previously reported that early arthritis (EA) patients with low vasoactive intestinal peptide (VIP) serum levels demonstrate a worse clinical disease course. In this study, we analysed whether variants in the VIP gene correlated with its serum levels and clinical EA parameters. The VIP gene was sequenced in patients with extremely high/low VIP levels, measured by enzyme immunoassay. Sixteen single nucleotide polymorphisms (SNPs) were diferentially distributed between both groups, which were subsequently genotyped in two patients’ sets. We observed that patients with rs688136 CC genotype showed higher VIP levels in both discovery (n=91; p=0.033) and validation populations (n=131; p=0.007). This efect was attenuated by the presence of minor alleles rs35643203 and rs12201140, which showed a clear trend towards low VIP level association (p=0.118 and p=0.049, respectively). Functional studies with miR-205-5p, which has a target site in the 3′ UTR close to rs688136, revealed a miRNA-mediated regulatory mechanism explaining the higher VIP gene expression in homozygous patients. Moreover, patients with an rs688136 CC genotype and no minor alleles of the other polymorphisms required less treatment (p=0.009). We concluded that the identifcation of polymorphisms associated with VIP serum levels would complement the clinical assessment of the disease severity in rheumatoid arthritis patients.Item Comparative study of senescent Th biomarkers in healthy donors and early arthritis patients. Analysis of VPAC receptors and their influence(Cells, 2020) Villanueva Romero, Raúl; Lamana Domínguez, Amalia; Flores Santamaría, Marissa; Carrión Caballo, Mar; Pérez García, Selene; Triguero-Martínez, Ana; Tomero, Eva; Criado, Gabriel; Pablos Álvarez, José Luis; González-Álvaro, Isidoro; Martínez Mora, María Del Carmen; Juarranz Moratilla, Yasmina; Pérez Gomáriz, Rosa María; Gutiérrez Cañas, IrenePro-inflammatory CD4+CD28− T cells are characteristic of immunosenescence, but also of several autoimmune/inflammatory diseases. Vasoactive intestinal peptide (VIP) acts as an anti-inflammatory and immunomodulatory mediator on these cells. Our objective was to study the mutual influence between senescent Th cells and VIP axis in early arthritis (EA), comparing with non-EA donors. We characterized the correlation between senescent Th cells and clinic parameters of EA as well as the behavior of senescent Th biomarkers by real-time PCR. Clinical data were systematically recorded at baseline and after 6 months of follow-up. The number of CD4+CD28− T cells measured by sorting is higher in patients who initially meet ACR classification criteria for rheumatoid arthritis (RA) compared to those who were classified as undifferentiated arthritis (UA). A slight positive correlation between EA CD4+CD28− T cells and CRP or ESR and a negative correlation with bone mineral density were found. Th senescent biomarkers in EA CD4+CD28− T cells were similar to donors, however some of them increased after 6 months of follow-up. VPAC receptors were analyzed by real-time PCR and immunofluorescence, and CD4+CD28− T cells showed higher expression of VPAC2 and lower of VPAC1, VPAC2 showing a significant increased expression in EA cells. Sorted CD4+CD28− T cells were in vitro expanded in presence of VIP, wherein VIP increased senescent biomarker CD27, while it diminished CD57 or NKG2 senescent biomarkers. Our study demonstrates for the first time the existence of a link between senescent Th cells and the VIP axis.
