Rabbits sensitized with whole nervous tissue or myelin basic protein (MBP) plus adjuvant and developing experimental allergic encephalomyelitis (EAE) were studied for the presence of oligoclonal immunoglobulin (Ig) bands in spinal fluid and serum. Samples obtained prior to sensitization and at the time of sacrifice were concentrated and subjected to agar(More)
Abrupt increases in blood-brain barrier (BBB) permeability were detected by the dual-isotope technique, coinciding with evidence of activation of coagulation cascade, occurred 1 day prior to appearance of clinical neurological signs of experimental allergic encephalomyelitis (EAE) and in conjunction with initial detectable cell infiltration. Maximal(More)
Oligoclonal IgG bands have recently been reported to occur in cerebrospinal fluid (CSF) and serum of rabbits with experimental allergic encephalomyelitis (EAE). To examine the specificity of these bands, a) individual bands eluted from rabbit CSF and sera were tested by radioimmunoassay (RIA) for anti-MBP activity and b) rabbit sera were absorbed with the(More)
Highly purified synthetic peptides representing portions of the 68-86 sequence of guinea pig (GP) myelin basic protein (GPMBP) were used to define the N- and C-termini of encephalitogenic determinants that cause experimental autoimmune encephalomyelitis (EAE) in Lewis rats. Each peptide was tested for: (a) induction of EAE, (b)in vitro potentiation of EAE(More)
The measurement of myelin basic protein serum factors (MBP-SFs) and anti-MBP antibodies in specimens from a patient with post-herpes simplex acute disseminated encephalomyelitis (ADE) is described. Transitory appearance of high affinity anti-MBP antibodies in the absence of detectable MBP-SFs was observed. This pattern was similar to that found previously(More)
Cyclophosphamide (CY) has been shown to reverse the signs of experimental allergic encephalomyelitis (EAE) even after the onset of neurological deficits. Because of the analogy of EAE to exacerbations of multiple sclerosis (MS) a clinical trial of CY in acute MS exacerbations was undertaken. A 'sequential criterion' method was used to minimize the size of(More)
The fine specificity of myelin basic protein (MBP) epitopes capable of eliciting in vivo delayed-type hypersensitivity responses in Lewis rats with experimental autoimmune encephalomyelitis (EAE) was compared to those eliciting in vitro antigen-specific T cell proliferation and augmentation of disease transfer. Utilizing a panel of synthetic peptides with(More)
This study utilized Lewis rats and the cell-transfer form of experimental allergic encephalomyelitis (EAE) to focus on two central nervous system microvascular alterations known to be intimately associated with early clinical neurological signs of the disease, namely increased vascular permeability and deposition of fibrin. The main objective of the work(More)
The efficacy of antigen-specific immunoregulation as a treatment for the efferent limb of an autoimmune disease was tested in a rat model of adoptive experimental autoimmune encephalomyelitis (EAE). Lewis rats receiving 4-5 x 10(7) guinea pig (GP) myelin basic protein (MBP)-activated lymph node T cell blasts from GPMBP/CFA sensitized donors routinely show(More)
Fibrinolytic activity in the form of plasminogen activator (PA) was assessed using a histochemical fibrin slide technique in spinal cords of normal Lewis rats and rats with the cell-transferred form of experimental allergic encephalomyelitis (EAE). PA was localized exclusively to blood vessels. Vessels in the leptomeninges had maximum activity. A(More)
