In solid organ transplantation, mesenchymal stem cell (MSC) therapy is strongly emerging among other cell therapies due to the positive results obtained in vitro and in vivo as an immunomodulatory agent and their potential regenerative role. We aimed at testing whether a single dose of MSCs, injected at 11 weeks after kidney transplantation for the(More)
Vitamin E (tocopherol) enhances the growth inhibitory effects of adriamycin (ADR) on a variety of cancer cells in vitro. The role of vitamin E (d-alpha-tocopheryl) acid succinate in adjuvant chemotherapy with ADR was assessed in DU-145 human prostatic carcinoma cells in culture. Adriamycin produced a dose-dependent growth inhibition of DU-145 cells. The(More)
The humoral branch of the immune response has an important role in acute and chronic allograft dysfunction. The CD40/CD40L costimulatory pathway is crucial in B- and T- alloresponse. Our group has developed a new small interfering RNA (siRNA) molecule against CD40 that effectively inhibits its expression. The aim of the present study was to prevent(More)
Ischemia-reperfusion occurs in a great many clinical settings and contributes to organ failure or dysfunction. CD154-CD40 signaling in leukocyte-endothelial cell interactions or T-cell activation facilitates tissue inflammation and injury. Here we tested a siRNA anti-CD40 in rodent warm and cold ischemia models to check the therapeutic efficacy and(More)
Lupus nephritis (LN) is an autoimmune disorder in which co-stimulatory signals have been involved. Here we tested a cholesterol-conjugated-anti-CD40-siRNA in dendritic cells (DC) in vitro and in a model of LPS to check its potency and tissue distribution. Then, we report the effects of Chol-siRNA in an experimental model of mice with established lupus(More)
BACKGROUND/AIMS Mutations in the PRSS1 and the SPINK1 genes have variably been associated with alcohol-related, idiopathic and hereditary chronic pancreatitis (CP). The aim of this study was to determine for the first time the significance of PRSS1, SPINK1 mutations and genetic variants of AAT in a group of Spanish patients with CP. METHODS 104(More)
INTRODUCTION Standard therapy with corticosteroids (CS) and cyclophosphamide (CYC) followed by azathioprine has been shown to improve renal and patient survival in ANCA-associated renal vasculitis (rAAV). Mycophenolate mofetil (MF) has been progressively introduced for the treatment of rAAV in the last years because of its immunosuppressive efficacy(More)
Capillary density (CD), capillary to fiber ratio (C/F), fiber cross sectional area (FCSA) and fiber composition were measured in the soleus and the gastrocnemius (medial head) muscles of rats weighing between 99 and 666 g. Muscle samples obtained from the anesthetized animal were rapidly frozen (-130 degrees C) sliced transversely at 16--18 micrometers, and(More)
The research field on extracellular vesicles (EV) has rapidly expanded in recent years due to the therapeutic potential of EV. Adipose tissue human mesenchymal stem cells (ASC) may be a suitable source for therapeutic EV. A major limitation in the field is the lack of standardization of the challenging techniques to isolate and characterize EV. The aim of(More)
