Polyadenylylated mRNA was purified from poly(I).poly(C)- and cycloheximide-superinduced human fibroblast (FS-4) cultures. The mRNA was subjected to electrophoresis through an agarose/CH3HgOH gel, and human fibroblast beta 1 and beta 2 interferon mRNAs were isolated. Each mRNA preparation was phosphorolyzed at 0 degrees C for 20 min by using a molar excess of polynucleotide phosphorylase to prod...
Chemokines play an important role in pathogenesis of multiple sclerosis (MS), mediating migration of leukocytes into the central nervous system. CCL2 (MCP-1) chemokine is expressed in astrocytes in MS lesions. The aim of the study was to evaluate the effect of a two-year treatment with IFN-beta 1a on serum CCL2 level in MS patients. CCL2 concentration in sera of 18 relapsing-remitting MS (RR-MS...
We report a man with type 1 diabetes mellitus, autoimmune hypothyroidism and a tentative diagnosis of multiple sclerosis. Following treatment with beta interferon, he developed systemic lupus erythematosus with pericarditis, pleural effusions, cerebral infarction associated with anti-phospholipid antibody and acute renal failure due to thrombotic microangiopathy. He responded well to immunosupp...
BACKGROUND In the Betaseron/Betaferon in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) study, interferon beta-1b delayed conversion to multiple sclerosis in patients with a first clinical event and at least 2 clinically silent brain magnetic resonance imaging (MRI) lesions. OBJECTIVE To examine detailed MRI findings from the first 2 years of this trial. DESIGN Double-bli...
multiple sclerosis (ms) is one of the most important autoimmune diseases recognized by demyelination and axonal lesion. it is the most common cause of disability in the young population. various immunomodulatory and immunosuppressive therapies, including different formulations of interferon beta (ifnβ), glatiramer acetate (ga), mitoxantrone, and natalizumab are available for this disease. howev...
conclusions these findings indicated the association of the hbsag titer and serum ifnar2 in hbsag clearance in hepatitis b virus- infected patients. in consequence, immune mechanisms related to ifn-α/β signaling might be responsible in chb outcome. background loss of hepatitis b surface antigen (hbsag) in chronic hepatitis b (chb) infection is a favorable outcome. type i interferon (ifni) has a...
Hantaviruses cause two diseases with prominent vascular permeability defects, hemorrhagic fever with renal syndrome and hantavirus pulmonary syndrome. All hantaviruses infect human endothelial cells, although it is unclear what differentiates pathogenic from nonpathogenic hantaviruses. We observed dramatic differences in interferon-specific transcriptional responses between pathogenic and nonpa...
The interferon-beta promoter binding protein, IRF-2, is proteolytically processed during induction by double-stranded RNA to leave an N-terminal fragment that can still bind to DNA. An N-terminal fragment that corresponds to the induction-specific product has a higher affinity for the promoter and is a more potent repressor of interferon-beta transcription than the full-length precursor. The ki...
