Heparin-binding growth factors have been implicated in central nervous system development, regeneration and pathology. To assess the expression pattern and possible function in multiple sclerosis, the heparin-binding growth factors pleiotrophin (PTN), midkine (MK), basic fibroblast growth factor (FGF-2) and one of its receptors (FGFR1/flg) mRNA and protein(More)
PURPOSE The purpose of this study was to determine the ability of three-dimensional in vivo MR microscopy to depict the treatment effects of insulin-like growth factor-I (IGF-I) in SJL mice with chronic relapsing experimental autoimmune encephalomyelitis (crEAE). METHODS The experiments were performed at 4.7-T on 10 crEAE mice and on one set of control(More)
The unlabeled peroxidase-antiperoxidase method has been used with antiserum against "myelin-associated glycoprotein" to establish the presence of the glycoprotein in myelin and myelin-forming cells of the developing rat nervous system. Myelin-associated glycoprotein is found in oligodendroglial cytoplasm before the beginning of myelination. Staining(More)
To compare effects of insulin-like growth factor I (IGF-I) and placebo treatment on lesions that resemble those seen during active demyelination in multiple sclerosis, we induced experimental autoimmune encephalomyelitis in Lewis rats with an emulsion containing guinea pig spinal cord and Freund's adjuvant. On day 12-13, pairs of rats with the same degree(More)
To localize basic protein (BP) in the lamellar structure of central and peripheral myelin, we perfused newborn and 7-11-day rat pups with a phosphate-buffered fixative that contained 4% paraformaldehyde and 0.05 or 0.2% glutaraldehyde. Teased, longitudinally split or "brush" preparations of optic and trigeminal nerves were made by gently teasing apart(More)
To investigate insulin-like growth factor I (IGF-I) and IGF-I receptor gene expression during experimental demyelination and myelin regeneration, young mice were fed cuprizone (( bis(cyclohexanone) oxaldihydrazone )). This copper-chelating agent produces demyelination in the corpus callosum and superior cerebellar peduncles, and when treatment is stopped,(More)
Our goal was to test the effects of insulin-like growth factor I (IGF-I) treatment on clinical deficits, lesion number and lesion size in acute demyelinating experimental autoimmune encephalomyelitis (EAE) induced in Lewis rats with an emulsion containing guinea pig spinal cord. In this EAE model, there is severe immune-mediated demyelination, which(More)
To assess the distribution of insulin-like growth-factor-related proteins during autoimmune CNS demyelination and remyelination, experimental autoimmune encephalomyelitis was produced by injecting Lewis rats with an emulsion containing guinea pig spinal cord and complete Freund's adjuvant. Tail weakness appeared at 10-12 days and was followed by hind and(More)
