Interaction forces and adhesion of supported myelin lipid bilayers modulated by myelin basic protein.
Force-distance measurements between supported lipid bilayers mimicking the cytoplasmic surface of myelin at various surface coverages of myelin basic protein (MBP) indicate that maximum adhesion and minimum cytoplasmic spacing occur when each negative lipid in the membrane can bind to a positive arginine or lysine group on MBP. At the optimal lipid/protein ratio, additional attractive forces ar...
متن کاملLipid domains control myelin basic protein adsorption and membrane interactions between model myelin lipid bilayers.
The surface forces apparatus and atomic force microscope were used to study the effects of lipid composition and concentrations of myelin basic protein (MBP) on the structure of model lipid bilayers, as well as the interaction forces and adhesion between them. The lipid bilayers had a lipid composition characteristic of the cytoplasmic leaflets of myelin from "normal" (healthy) and "disease-lik...
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 کاملISOLATION 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 کاملAdsorption mechanism of myelin basic protein on model substrates and its bridging interaction between the two surfaces.
Myelin basic protein (MBP) is an intrinsically disordered (unstructured) protein known to play an important role in the stability of myelin's multilamellar membrane structure in the central nervous system. The adsorption of MBP and its capacity to interact with and bridge solid substrates has been studied using a surface forces apparatus (SFA) and a quartz crystal microbalance with dissipation ...
