In the central nervous system glial-derived S100B protein has been associated with inflammation via nitric oxide (NO) production. As the role of enteroglial cells in inflammatory bowel disease has been poorly investigated in humans, we evaluated the association of S100B and NO production in ulcerative colitis (UC). S100B mRNA and protein expression,(More)
Increased activity of plasma membrane K+ channels, leading to decreased cytoplasmic K+ concentrations, occurs during neuronal cell death. In the present study, we showed that the neurotoxic beta-amyloid peptide Abeta(25-35) caused a dose-dependent (0.1-10 microm) and time-dependent (> 12 h) enhancement of both inactivating and non-inactivating components of(More)
AIMS FK506-binding protein (FKBP) 12 is an inhibitor of transforming growth factor (TGF)-beta type I receptors. Several lines of evidence support the view that TGF-beta stimulates vascular smooth muscle cell (VSMC) proliferation and matrix accumulation. We investigated the effect of FK506, also known as tacrolimus, on cellular proliferation and on matrix(More)
Although several glioma models exist, systematic morphometrical studies on such experimental tumors are lacking. The purpose of this study was the quantitative assessment of how rat strains, cell lines, injection techniques and location affect tumors reproducibility and histopathological features. Glioma cells were implanted in 3 brain locations, with(More)
B-cell lymphoma is associated with incomplete response to treatment, and the development of effective strategies targeting this disease remains challenging. A new personalized B-cell lymphoma therapy, based on a site-specific receptor-mediated drug delivery system, was developed in this study. Specifically, natural silica-based nanoparticles (diatomite)(More)
Alzheimer's disease (AD) is characterized by chronic deposition of β-amyloid (Aβ) in the brain, progressive neurodegeneration and consequent cognitive and behavioral deficits that typify the disease. Astrocytes are pivotal in this process because they are activated in the attempt to digest Aβ which starts a neuroinflammatory response that further(More)
