In this study, we demonstrate for the first time the immunohistochemical expression of citrullinated proteins in the central nervous system (CNS) of mice with myelin oligodendrocyte glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE). By using an established monoclonal antibody (F95) against natural and synthetic citrullinated(More)
In this study, we demonstrate that grossly unaffected white matter from secondary progressive multiple sclerosis (SP-MS) patients is heavily citrullinated, as compared to normal white matter from control patients. Citrullination was most pronounced at plaque interfaces and was shown to colocalize with glial fibrillary acidic protein (GFAP)-immunoreactivity(More)
By using hybridoma technology, an IgM monoclonal antibody (F95) against multiple citrullinated synthetic and natural peptides was recently developed and used to stain immunohistochemically subsets of astrocytes and myelin basic protein (MBP) from selected regions of human brain (Nicholas and Whitaker [2002] Glia 37:328-336). With this antibody, the present(More)
There is ample documentation of the binding of chondroitin sulfate/dermatan sulfate proteoglycans to low density lipoprotein (LDL) both in vivo and in vitro. The interaction of these two species may be an early and important step in atherogenesis. Therefore, there is interest in defining the features of both molecules that are critical for their(More)
Peptidylarginine deiminase type II (PAD 2) is the primary enzyme responsible for conversion of protein bound arginine to citrulline in the central nervous system. Evidence suggests that glial fibrillary acidic protein (GFAP), the main intermediate filament in astrocytes, is deiminated, but not much is known regarding factors that control this enzymatic(More)
An enzyme capable of cleaving catechin was present in the mycelium ofCheatomium cupreum. Maximum synthesis of the enzyme occurred after 15 days growth. Sucrose and maltose increased enzyme synthesis among the carbon sources tested. Catechol, protocatechuic acid and phloroglucinol carboxylic acid were the intermediates of catechin degradation.Cheatomium(More)
Surface adherent immunoglobulins are potent stimuli for inducing neutrophil release of myeloperoxidase and production of hypochlorous acid (HOCl), an oxidant that promotes activity of neutrophil proteases. Opsonization of surface adherent IgG (SAIgG) by complement results in attenuation of these responses, despite augmenting neutrophil production of(More)
