encephalomyelitis/protease

The in vitro activity of gelatinase B, an enzyme whose appearance in the cerebrospinal fluid is associated with inflammatory diseases of the central nervous system, was dose-dependently inhibited by the antirheumatic D-penicillamine. Inhibition of gelatinase B in electrophoretically pure

Defined DNA fragments of cloned Theiler's murine encephalomyelitis virus genome were used to construct procaryotic recombinant plasmids expressing viral genes 3C and 3D. In these plasmids (pEX-EMBL vectors), viral sequences are fused in-phase behind the Escherichia coli lac Z' gene which is under

Experimental allergic encephalomyelitis (EAE) is an experimentally induced autoallergic demyelinating disease which is caused by immunization with a particular neuroantigen, such as myelin basic protein (MBP). Results have suggested that protease inhibitors might be useful therapeutically. Leupeptin

The genetic predisposition to multiple sclerosis (MS) is most strongly conveyed by MHC class II haplotypes, possibly by shaping the autoimmune CD4 T cell repertoire. Whether Ag-processing enzymes contribute to MS susceptibility by editing the peptide repertoire presented by these MHC haplotypes is

Multiple sclerosis (MS) is characterized by axonal demyelination and neurodegeneration, the latter having been inadequately explored in the MS animal model experimental autoimmune encephalomyelitis (EAE). The purpose of this study was to examine the time-dependent correlation between increased

Multiple sclerosis is a neurodegenerative disease affecting predominantly female patients between 20 and 45 years of age. We previously reported the significant contribution of mouse mast cell protease 4 (mMCP-4) in the synthesis of endothelin-1 (ET-1) in healthy mice and in a murine model of

Two kinds of neutral protease activities in lymph nodes from Lewis rats with acute experimental allergic encephalomyelits (EAE) have been separated and partially purified and characterized. A soluble enzyme preparation enriched by gel filtration and ion-exchange chromatography hydrolyzes myelin

Experimental autoimmune encephalomyelitis (EAE) is a mouse model that reproduces cardinal signs of clinical, histopathological, and immunological features found in Multiple Sclerosis (MS). Mast cells are suggested to be involved in the main inflammatory phases occurring during EAE development,

Mast cell populations were identified within brain parenchyma by their specific proteases, using antibodies for immunohistochemistry and ELISAs, and riboprobes were developed for in situ hybridisation. Connective tissue mast cells expressing rat mast cell protease I (RMCPI) mRNA and immunoreactivity

Members of the papain family of cysteine proteases (cathepsins) mediate late stage processing of MHC class II-bound invariant chain (Ii), enabling dissociation of Ii, and binding of antigenic peptide to class II molecules. Recognition of cell surface class II/Ag complexes by CD4(+) T cells then

Inhibitors of proteolytic enzymes were tested for their ability to suppress the clinical signs and CNS lesions produced by injection of purified myelin in complete Freund's adjuvant into Lewis rats. Pepstatin or a series of neutral protease inhibitors including aprotinin, soybean trypsin inhibitor,

Available treatments for multiple sclerosis (MS) require frequent injections and have significant side effects. Proteases generated during inflammation are involved in the induction of tissue damage during inflammatory demyelination in the central nervous system (CNS). The Bowman-Birk Inhibitor

To evaluate the question of whether protease activated receptor-1 (PAR-1) antagonist is a potential therapeutic target in multiple sclerosis, we treated experimental autoimmune encephalomyelitis (EAE) mice with two PAR-1 antagonists, KC-A0590 and SCH-530348. Treatment with both antagonists resulted

Lymphocytes from popliteal and inguinal lymph nodes of Lewis rats with acute EAE as a result of injection of lyophilized guinea pig myelin in Freund's complete adjuvant exerted strong proteolytic activity at neutral pH toward myelin basic protein. After injection of myelin the level of proteolytic
