What does myelin basic protein stain?
Note that the MBP antibody stains an oligodendrocyte and some membrane shed from this cell. Other cells in the field include neurons, astrocytes, microglia and fibroblasts, all of which are completely negative for MBP, though the neuronal processes can be seen with the NF-L antibody.
How is myelin basic protein detected?
A sensitive enzyme-linked immunosorbent assay for myelin basic protein has been recently developed, which can make a clinical evaluation of myelin basic protein in cerebrospinal fluid of patients with multiple sclerosis and other neurological diseases.
What is myelin basic protein multiple sclerosis?
Myelin basic protein (MBP) is an abundant protein in central nervous system (CNS) myelin. MBP has long been studied as a factor in the pathogenesis of the autoimmune neurodegenerative disease multiple sclerosis (MS). MS is characterized by CNS inflammation, demyelination, and axonal loss.
Where is myelin basic protein expressed?
The myelin basic protein gene is expressed in differentiated blood cell lineages and in hemopoietic progenitors | PNAS.
What does Oligoclonal bands in CSF mean?
CSF is the clear fluid that flows in the space around the spinal cord and brain. Oligoclonal bands are proteins called immunoglobulins. The presence of these proteins indicates inflammation of the central nervous system. The presence of oligoclonal bands may point to a diagnosis of multiple sclerosis.
How do you test for myelin?
When the marker, known as MeDAS, is given to the patient through an IV injection, it can easily reach the brain and spinal cord and bind to the patient’s myelin sheaths. The PET scanner then visualizes where the marker has accumulated in the patient’s body.
Is MBP a membrane protein?
Among these, MBP is probably the most frequently used fusion protein for membrane proteins.
Where is myelin basic protein made?
Myelin basic proteins are a group of seven proteins produced from a single gene mapped to chromosome 18q22–q23 by alternate splicing, and found in the central and peripheral nervous system myelin.
Do Schwann cells express MBP?
We find that P0+ Schwann cells in serum-free medium express a mixture of myelinating and nonmyelinating phenotypic markers—in that they express abundant MBP, LNGFR, and the O4 antigen, as well as low levels of GC.
What do positive oligoclonal bands mean?
Oligoclonal bands are proteins called immunoglobulins. The presence of these proteins indicates inflammation of the central nervous system. The presence of oligoclonal bands may point to a diagnosis of multiple sclerosis.
How multiple sclerosis is diagnosed?
No one test can provide a definitive MS diagnosis. To understand what’s causing symptoms, your healthcare provider will do a physical exam. You may also have blood tests and imaging tests, such as MRI. An MRI looks for evidence of lesions (areas of damage) in the brain or spinal cord that indicate multiple sclerosis.
What is the difference between MS and demyelination?
Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system. In this disorder, your immune system attacks the myelin sheath or the cells that produce and maintain it. This attack causes inflammation and injury to the nerve sheath and ultimately to the nerve fibers that it surrounds.
What can MBP be used for?
Maltose-binding protein (MBP) is one of the most popular fusion partners being used for producing recombinant proteins in bacterial cells. MBP allows one to use a simple capture affinity step on amylose-agarose columns, resulting in a protein that is often 70-90% pure.
How many amino acids are in myelin basic protein?
169 amino acid
The major basic protein is a 169 amino acid peptide, which comprises 30% of the myelin content.
Which cells express myelin basic protein?
The myelin basic protein gene is expressed in differentiated blood cell lineages and in hemopoietic progenitors. Proc Natl Acad Sci U S A. 2002 Jun 25;99(13):8856-61.
