Microcalorimetric studies of the heats of solution of bovine myelin basic protein.

چکیده
Heats of solution for myelin basic protein have been determined using microcalorimetry. All aqueous systems studied yielded negative heats of solution; in contrast, trifluoroethanol produced a small positive heat of solution, while reaction with dimethyl sulfoxide was strikingly exothermic. The heat of interaction for native myelin basic protein with 8 M urea at pH 4.0, 29 degrees C, was found to be -79 +/- 16 kcal/mol. The significance of these results in terms of the protein's structural organization is discussed.

ISOLATION OF MYELIN BASIC PROTEIN AND DETECTION OF I TS IMMUNOL\'OGICAL PROPERTIES
Multiple sclerosis (MS) is an inflammatory disease of the central nervous system of presumed autoimmune etiology. One of the best animal models of demyelinating diseases is experimental autoimmune encephalomyelitis (EAE), which can be induced in a variety of animals by injection of a target antigen such as myelin basic protein (MBP). The immune responses against the target amino acids caus...
متن کاملDesigning, Optimization and Construction of Myelin Basic Protein Coding Sequence Binding to the Immunogenic Subunit of Cholera Toxin
Abstract Background and Objectives: Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease. Mucosal feeding of myelin basic protein binding to the cholera toxin B subunit can reduce the intensity of the immune response in MS patients. Expression system, the domain composition of the fusion protein, accessibility of two domains, codon adaptation index (CAI) and GC contents are v...
متن کاملSerum and Saliva Myelin Basic Protein as Multiple Sclerosis Biomarker
Objective: Multiple sclerosis (MS) is presented with motor and sensory function loss. It is caused by demyelination and following axonal lesion. As myelin basic protein (MBP) is one of the key elements of the myelin cover, we examined the level of MBP in serum, stimulated, and unstimulated saliva as a suitable biomarker for detecting MS. Methods: A case-control study was performed in 29 health...
متن کاملCombination of Myelin Basic Protein Gene Polymorphisms with HLA-DRB1*1501 in Iranian Patients with Multiple Sclerosis
Background: Multiple sclerosis (MS), as a multifactorial autoimmune disease with complex genetic basis, causes demyelination in the central nervous system via cytokine responses to myelin antigens. Myelin basic protein (MBP) is the main protein component of the myelin sheath. HLA-DRB (human leukocyte antigen-DR beta) alleles, particularly HLA-DRB1*1501, may be of significance in the pathogenesi...

Hematite (α-Fe2O3) nanorods were synthesized by hydrothermal method using Cetyltrimethylammonium bromide (CTAB) as a surfactant agent. To study optical, nanostructural properties, and to control the morphology and shape of nanorods, 0.025 mol L-1, 0.05 mol L-1 and 0.1 mol L-1 concentration of CTAB were used. Moreover, the effect of interaction between bovine serum albumin (BSA) A9418-5G protein...
