An acute form of transferred experimental allergic encephalomyelitis was induced by injection of activated, myelin basic protein-specific T cell line lymphocytes. The course of the disease as a function of the dose of cytotoxic cells was investigated, and the effect of i.p. and i.v. application of methotrexate on mortality and morbidity was determined.(More)
OBJECTIVES The most frequent sporadic adult motor neuron disease, amyotrophic lateral sclerosis, affects more men, follows no epidemiologic pattern, and was long considered a pure spinal cord disorder. It now becomes evident that the disease is characterized by spinal, cerebral and extra-neuromuscular changes including B-cellular responses and(More)
Antisera were raised in rabbits against five synthetic peptides. These peptides have been identified as potentially antigenic epitopes from the sequence of porcine choline acetyltransferase (ChAT) using primary and secondary structure analysis. All five antisera recognized immunoaffinity-purified antigen from porcine brain in an ELISA and on western blots.(More)
Systemic therapy of encephalitis with human interferon-beta regularly causes fever up to more than 41 degrees C. Patients often developed hematological changes, nausea and tachycardia. Analyzing the temperature curves of 13 patients with repeated intrathecal, lumbar instillations of 1.0 x 10(6) IU natural IFN-beta, we found markedly less drug-associated(More)
Sporadic amyotrophic lateral sclerosis may be an aetiologically heterogenous disease. We confirmed elevated circulating IgG immune complexes, and altered IgG seroreactivities against human retroviral antigens (HIV-2 and HTLV immunoblots) in overlapping subgroups of patients. Together with preliminary findings of a positive polymerase chain reactivity for(More)
Motor neuron disease (MND) represents one ofthe major unsolved problems in neurology. The literature is characterized by numerous speculative theories, mostly derived by analogy with other recognized causes of motor neuron death such as poliomyelitis, or from toxic exposures such as lead poisoning. However, analogous reasoning of this type has not, so far,(More)
In an attempt to verify the possible role of retrovirus in idiopathic amyotrophic lateral sclerosis (ALS), the sera of 21 ALS patients admitted to the Neurological Unit of the Don Gnocchi Foundation in Milan, Italy, and of 9 ALS patients from Ulm University in Germany have been evaluated for the presence of antibodies to the human T-lymphotropic viruses(More)
Successfully inducing differentiation in ectodermal diseases, retinoids harbour considerable therapeutic potential in the treatment of neuroectodermal-neuroepithelial malignancies. The principal tissue retinoid, retinoic acid, can be potently upregulated in vivo by a relatively specific catabolic inhibitor, R75251 (liarozole). Both substances have been(More)
Eight years after diagnosis, 40% of MS patients develop a chronically progressive form. Annually we treat approximately 200 patients with progressive MS. Treatment consists of medication, i.e. agents that help to prevent future impairment, or interferon-beta injections, and intervals of mitoxantrone infusions (Novantrone(R)), and in some cases cyclic(More)
Out of 50 patients with sporadic amyotrophic lateral sclerosis (sALS), excluding 8 patients with recent immunosuppressive medication or low total IgG, we examined all available 92 sera of 11 women and 31 men nephelometrically for serum immunoglobulin concentrations including IgG isotypes IgG1-4. Mean serum levels of IgA and IgM remained within references in(More)
