We constructed a transgenic mouse model that mimics the human autoimmune disease multiple sclerosis in its spontaneous induction and pathology. Transgenic mice were constructed expressing genes encoding a rearranged T cell receptor specific for myelin basic protein (MBP). T cell tolerance was not induced in the periphery, and functional, autoreactive T(More)
When 251 relapsing-remitting patients with multiple sclerosis were randomized to receive daily subcutaneous injections of glatiramer acetate, previously called copolymer 1 (Copaxone; n = 125) or placebo (n = 126) for 24 months, there were no laboratory abnormalities associated with glatiramer acetate treatment and it was well tolerated with few side(More)
To analyze the pathogenesis of the neurotropic murine coronavirus JHMV, we used monoclonal antibodies to the E2 viral glycoprotein to select antigenic variant viruses. Monoclonal antibodies J.7.2 and J.2.2 were shown to bind to topographically distinct regions of the E2 molecule, and the variants selected with the two antibodies demonstrated very different(More)
The transferrin receptor (TfR) binds two proteins critical for iron metabolism: transferrin (Tf) and HFE, the protein mutated in hereditary hemochromatosis. Previous results demonstrated that Tf and HFE compete for binding to TfR, suggesting that Tf and HFE bind to the same or an overlapping site on TfR. TfR is a homodimer that binds one Tf per polypeptide(More)
Monoclonal antibodies were produced to JHMV-DL, a neurotropic member of the mouse hepatitis virus (MHV) or murine coronavirus group. Of 23 antibodies isolated, 10 were specific for the major envelope glycoprotein, gp180/90, 10 for the nucleocapsid protein, pp60, and 3 for the minor envelope glycoprotein, gp25. Eleven different MHV isolates were used in(More)
The pathogenesis of murine hepatitis virus, strain JHM, was studied in 6- and 12-week-old C57/BL mice. There was 100% mortality in the 6-week-old mice after intracerebral inoculation. The lesions were characterized by necrotizing encephalomyelitis, without demyelination. Intracerebral inoculation of 12-week-old animals, however, resulted in no morbidity or(More)
This report describes advances in techniques for analyzing cellular and humoral immune components in the cerebrospinal fluid (CSF) of the mouse that are applicable to other laboratory animals. CSF studies undertaken during experimental infection of mice with JHM strain virus (JHMV) of mouse hepatitis virus are presented. A critical pitfall which can lead to(More)
The present clinical trial was undertaken to assess the clinical safety and possible efficacy of administering tamoxifen to patients with recurrent malignant glial tumors at dosages calculated to achieve levels sufficient to inhibit protein kinase C within the tumor cells. Chronic p.o. tamoxifen was administered in very high dosages to 32 patients (20 males(More)
