In this study, we used deletions at 22q13, which represent a substantial source of human pathology (Phelan/McDermid syndrome), as a model for investigating the molecular mechanisms of terminal deletions that are currently poorly understood. We characterized at the molecular level the genomic rearrangement in 44 unrelated patients with 22q13 monosomy(More)
Interleukin-1alpha (IL-1alpha) and IL-1beta are two pro-inflammatory cytokines involved in the pathogenesis of Alzheimer's disease (AD). The genes coding for IL-1alpha (IL-1A) and for IL-1beta (IL-1B) are clustered in chromosome 2q14-2q14.2. In a previous work, we investigated the role of IL-1A promoter polymorphism (-889 position) in AD pathogenesis: IL-1A(More)
Plasma levels of alpha1-antichymotrypsin (ACT) and interleukin-1beta (IL-1beta) were increased in patients with probable Alzheimer's disease (AD). A common polymorphism within ACT and IL-1beta genes affected plasma levels of ACT or IL-1beta, and AD patients with the ACT T,T or IL-1beta T,T genotype showed the highest levels of plasma ACT or IL-1beta,(More)
Chemotherapy in glioma is poorly effective: the blood-brain barrier and intrinsic and/or acquired drug resistance of tumor cells could partly explain this lack of major effect. We investigated expression of P-glycoprotein (Pgp), multidrug resistance protein (MRP) 1, MRP3, MRP5 and glutathione-S-transferase pi (GST-pi) in malignant glioma patients.(More)
The mesothelium is a flat epithelial lining of serous cavities that could gate the traffic of molecules and cells between the circulation and these body compartments. The present study was designed to elucidate the capacity of mesothelial cells to express adhesion molecules and chemoattractant cytokines, two fundamental mechanisms of regulation of leukocyte(More)
In this study, we analysed the polymorphic variants of IL-1alpha (C-T transition at position -889), IL-1beta (C-T transition at position -511) and IL-1 receptor antagonist (Ra) (86-bp repeated sequence in intron 2) in 1131 subjects (453 females and 678 males) from Northern and Central Italy, including 134 centenarians, to evaluate whether IL-1 cluster(More)
The A1/A1 genotype of the anti-inflammatory cytokine interleukin 1 receptor antagonist (IL-1Ra) polymorphism was more frequent in 339 Italian MS patients than in healthy controls (HCs) (odds ratio = 1.83). A more aggressive disease course was also associated with A1+ genotypes and might reflect the reduced ability of mononuclear cell cultures of A1+ HCs to(More)
Recent studies have shown an anti-tumour activity of cannabinoid receptors CB1 and CB2 in gliomas. This effect was mediated by neurotrophins in breast and prostate carcinoma, while in gliomas this relationship has not yet been considered. The aim of this study was to investigate the expression of cannabinoid receptors CB1 and CB2, neurotrophin NGF and NT-3(More)
IFNbeta has been the first drug approved for the treatment of multiple sclerosis patients, but we still lack a full understanding of the mechanisms underlying its clinical effects and the great variability of its therapeutic efficacy among different patients. Serum levels of the anti-inflammatory cytokine IL-1 receptor antagonist increase after IFNbeta(More)
