A newly established murine immature dendritic cell line can be differentiated into a mature state, but exerts tolerogenic function upon maturation in…
2007
AbstractThe phenotype and function of murine dendritic cells (DCs) are primarily studied using bone-marrow–derived DCs (BM-DCs), but may be hampered by the heterogenous phenotype of BM-DCs due to their differential state of maturation. Here we characterize a newly established murine DC line (SP37A3) of myeloid origin. During maintainance in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) and M-CSF, SP37A3 cells resemble immature DCs characterized by low expression of major histocompatibility complex (MHC) II and costimulatory molecules and low T-cell stimulatory capacity. Upon stimulation, SP37A3 cells acquire a mature phenotype and activate naive T cells as potent…
Anti-Inflammatory Triterpenes from Pistacia terebinthus Galls
2002
From the galls of Pistacia terebinthus we obtained an extract that proved to be effective against chronic and acute inflammation. Now we report on the isolation and identification of three triterpenes: two tirucallane-type lanostanoids and one oleanane, which we have identified as masticadienonic acid (1), masticadienolic acid (2), and morolic acid (3), respectively. All of them showed effectiveness on the mouse ear inflammation induced by repeated applications of 12-O-tetradecanoylphorbol 13-acetate and on the phospholipase A2-induced foot paw edema. The pharmacological activity of the compounds was ratified by a histological study of the ear samples. In addition, they inhibited leukotrien…
A new p65 isoform that bind the glucocorticoid hormone and is expressed in inflammation liver diseases and COVID-19
2021
AbstractInflammation is a physiological process whose deregulation causes some diseases including cancer. Nuclear Factor kB (NF-kB) is a family of ubiquitous and inducible transcription factors, in which the p65/p50 heterodimer is the most abundant complex, that play critical roles mainly in inflammation. Glucocorticoid Receptor (GR) is a ligand-activated transcription factor and acts as an anti-inflammatory agent and immunosuppressant. Thus, NF-kB and GR are physiological antagonists in the inflammation process. Here we show that in mice and humans there is a spliced variant of p65, named p65 iso5, which binds the corticosteroid hormone dexamethasone amplifying the effect of the glucocorti…

Pomalidomide plus low-dose dexamethasone in patients with relapsed/refractory multiple myeloma and renal impairment: Results from a phase ii trial
2018
Purpose Renal impairment (RI) limits treatment options in patients with relapsed/refractory multiple myeloma (RRMM). Here, we prospectively studied pomalidomide plus low-dose dexamethasone (LoDEX) in patients with RRMM and moderate or severe RI, including those receiving hemodialysis. Patients and Methods MM-013, a noncomparative, European phase II trial, enrolled three patient cohorts: moderate RI (cohort A; estimated glomerular filtration rate, 30 to < 45 mL/min/1.73 m2); severe RI (cohort B; estimated glomerular filtration rate, < 30 mL/min/1.73 m2); and severe RI that requires hemodialysis (cohort C). Patients received pomalidomide 4 mg/d on days 1 to 21 and LoDEX 20 or 40 mg once…
Chemoimmunotherapy with methotrexate, cytarabine, thiotepa, and rituximab (MATRix regimen) in patients with primary CNS lymphoma: results of the firs…
2016
BACKGROUND: Standard treatment for patients with primary CNS lymphoma remains to be defined. Active therapies are often associated with increased risk of haematological or neurological toxicity. In this trial, we addressed the tolerability and efficacy of adding rituximab with or without thiotepa to methotrexate-cytarabine combination therapy (the MATRix regimen), followed by a second randomisation comparing consolidation with whole-brain radiotherapy or autologous stem cell transplantation in patients with primary CNS lymphoma. We report the results of the first randomisation in this Article.METHODS: For the international randomised phase 2 International Extranodal Lymphoma Study Group-32 …
Suppressed Levels of Serum Cortisol Following High-Dose Oral Dexamethasone Administration Differ between Healthy Postmenopausal Females and Patients …
2001
Hypercortisolism and glucocorticoid treatment, even in a low dose or administered topically, may influence bone metabolism. It was the aim of this study to investigate whether there might be differences in the regulation of endogenous cortisol secretion between patients with established primary vertebral osteoporosis and healthy controls. Suppressed morning serum cortisol concentrations in a 3 mg dexamethasone overnight suppression test were compared in well-defined healthy postmenopausal women (n = 149) and osteoporotic patients classified as having established primary vertebral osteoporosis with no clinical features of hypercortisolism (n = 78). Suppressed cortisol in the healthy controls…
Efficacy and safety of preoperative IOP reduction using a preservative-free fixed combination of dorzolamide/timolol eye drops versus oral acetazolam…
2017
Introduction To demonstrate that preoperative treatment for 28 days with topical dorzolamide/timolol is non-inferior (Δ = 4 mm Hg) to oral acetazolamide and topical dexamethasone (standard therapy) in terms of intraocular pressure (IOP) reduction 3 and 6 months after trabeculectomy in glaucoma patients. Materials and methods Sixty-two eyes undergoing trabeculectomy with mitomycin C were included in this monocentric prospective randomized controlled study. IOP change between baseline and 3 months post-op was defined as the primary efficacy variable. Secondary efficacy variables included the number of 5-fluorouracil (5-FU) injections, needlings, suture lyses, preoperative IOP change, hyperten…
Controlled transdermal iontophoresis for poly-pharmacotherapy: Simultaneous delivery of granisetron, metoclopramide and dexamethasone sodium phosphat…
2015
Iontophoresis has been used to deliver small molecules, peptides and proteins into and across the skin. In principle, it provides a controlled, non-invasive method for poly-pharmacotherapy since it is possible to formulate and to deliver multiple therapeutic agents simultaneously from the anodal and cathodal compartments. The objective of this proof-of-principle study was to investigate the simultaneous anodal iontophoretic delivery of granisetron (GST) and metoclopramide (MCL) and cathodal iontophoresis of dexamethasone sodium phosphate (DEX-P). In addition to validating the hypothesis, these are medications that are routinely used in combination to treat chemotherapy-induced emesis. Two p…
Efficacy of posaconazole and amphotericin B in experimental invasive pulmonary aspergillosis in dexamethasone immunosuppressed rats
2007
Objectives: Invasive pulmonary aspergillosis is associated with high mortality. To assess new antifungal therapy options, animal models have to be developed to assess, in an appropriate setting, the activity of new drugs. Methods: Male albino CD rats (125–150 g) were fed with a protein-free diet and received dexamethasone thrice weekly subcutaneously during the whole experiment. After 2 weeks, an inoculum of 10 6 conidia of Aspergillus fumigatus (H11-20) was injected intratracheally. Antifungal treatment was initiated and continued for a total of 7 days. Animals were grouped in numbers of 10. One group of animals served as untreated control, whereas the others were treated with amphotericin…
