Eight relapsing-remitting multiple sclerosis (MS) patients were tested for the level of transforming growth factor beta1 (TGFbeta1) mRNA in peripheral blood mononuclear cells every 15 days for 6 months. Disease activity was evaluated every 4 weeks by magnetic resonance imaging (MRI) and neurological examination. An inverse correlation was found between the(More)
Subsets of neurons ensheathed by perineuronal nets containing chondroitin unsulfated proteoglycan have been immunohistochemically mapped throughout the rat central nervous system from the olfactory bulb to the spinal cord. A variable proportion of neurons were outlined by immunoreactivity for the monoclonal antibody (Mab 1B5), but only after chondroitinase(More)
Quantification of tumor necrosis factor-alpha (TNF-alpha) mRNA in peripheral blood mononuclear cells (PBMC) could provide information about disease activity in multiple sclerosis (MS); however, specific competitive methods must be utilized. A competitor cDNA, having the same sequence of the target TNF-alpha cDNA, a part from an internal 49-bp deletion, was(More)
Recently we reported that the keratan sulphate epitope recognised by the monoclonal antibody 5D4 is expressed by a population of ramified microglia in adult rats. As ramified microglia is believed to differentiate from ameboid microglia during postnatal development, we studied the rat brain from birth to 90 postnatal days of life with the monoclonal(More)
Microglia expressing keratan sulfate (KS) was studied in normal central nervous system (CNS) and in rat neonatal brain cultures. The majority of KS+ cells are ramified microglia located in the brain parenchyma; positive cells were only exceptionally found in extraparenchymal structures. KS+ cells are ubiquitous, but their density is heterogeneous throughout(More)
Anti-chondroitin unsulfated proteoglycan (COS-PG) 1B5 monoclonal antibody (MAb) and Vicia villosa agglutinin (VVA) recognize the same neuronal subset. Moreover, when in double immunofluorescence study the sections were digested with chondroitinase ABC (ChABC), a procedure necessary to create the epitope of 1B5 MAb, and incubated with VVA, no VVA positive(More)
Pig endocardiosis is a pathological process affecting cardiac valves that is characterised by the accumulation of glycosaminoglycans (GAG) in the extracellular matrix. To investigate the involvement of GAG in the condition, the morphology of the mitral valves from 23 affected pigs and seven normal controls was studied and qualitative and quantitative(More)
BACKGROUND Routine rapid testing for Bovine Spongiform Encephalopathy (BSE) has highlighted some problems with BSE rapid test performance, the most significant being the number of initially reactive samples and the false positive results on autolyzed tissue. This point is important for BSE active surveillance in risk populations, because tissue autolysis is(More)
The localization of calcitonin gene-related peptide (CGRP)-like immunoreactivity in the adrenal gland of the frog, Rana ridibunda, was examined by the indirect immunofluorescence technique. Using an antiserum directed against rat alpha-CGRP, the presence of a network of positive fibers was observed in the adrenal parenchyma. The immunoreactive material has(More)
