Growth-associated alterations in the oligosaccharide structures of transferrin secreted by HepG2 cells were examined by concanavalin A-crossed affinoimmuno-electrophoresis. Slowly dividing, confluent cultures produced transferrin with a approximately 4.5-fold greater proportion of biantennary complex-type oligosaccharides than rapidly dividing, subconfluent cultures. The activity of N-acetylglu...
The clinical, neuropathological genetic and biochemical features of variant Creutzfeldt-Jakob disease (vCJD) are compared to the 926 other cases of suspected CJD referred to the National CJD Surveillance Unit laboratory from 1990-2001. Histological studies of the central nervous system, lymphoid tissues and other organs were accompanied by immunocytochemistry for prion protein (PrP); Western bl...
Osteopontin (OPN) is a T helper type 1 immunoregulatory cytokine that plays a critical role in various inflammatory disorders. OPN exerts proinflammatory reactions through interaction with integrin receptors. OPN function can be modulated by protease digestion. However, the molecular mechanisms that regulate OPN function in vivo have not been elucidated. There are two putative heparin-binding d...
Using digitally analyzed fluorescence videomicroscopy, we have examined the behavior of acetylcholine receptors and concanavalin A binding sites in response to externally applied electric fields. The distributions of these molecules on cultured Xenopus myoballs were used to test a simple model which assumes that electrophoresis and diffusion are the only important processes involved. The model ...
Embryonic tissue cells dissociated with ethylenediaminetetraacetate are readily agglutinated by the carbohydrate-binding protein concanavalin A. In this property, they resemble transformed, neoplastic cells; and they differ from untransformed adult cells, which are agglutinated by concanavalin A only after their receptors are unmasked by proteolytic treatment. Receptor sites for wheat germ aggl...
Normal human monocytes and macrophages generate potent procoagulant activity (PCA) resembling tissue factor (TF) in response to various stimuli. In this study we show that tuftsin, a natural stimulator of many functions of monocytes and macrophages, also stimulates a potent PCA in mixed mononuclear cells and monocytes, and a mild PCA in lymphocytes and cell lines of monocytic origin (U937 and T...
Objective. 15-Deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) reduces inflammation and has been identified as an anti-inflammatory prostaglandin in numerous animal models. In this study, we investigated both effects of 15d-PGJ2 and its protection mechanism in concanavalin A- (ConA-) induced autoimmune hepatitis in mice. Materials and Methods. In vivo, Balb/C mice were injected with ConA (25 mg/kg) to ...
Maternal immune activation (MIA) is a potential risk factor for autism spectrum disorder (ASD) and schizophrenia (SZ). In rodents, MIA results in changes in cytokine profiles and abnormal behaviors in the offspring that model these neuropsychiatric conditions. Given the central role that mitochondria have in immunity and other metabolic pathways, we hypothesized that MIA will result in a fetal ...
Binding of a transition metal ion to specific sites in concanavalin A induces the formation of specific Ca(2+) ion-binding sites. Sites for binding alpha-methyl d-glucopyranoside exist only when a transition metal ion and Ca(2+) ion are bound.
