Mouse monoclonal and rabbit polyclonal antibodies prepared to human myelin-associated glycoprotein also react with glycosphingolipids of peripheral nerve. 1986

A A Ilyas, and M J Dobersen, and H J Willison, and R H Quarles

A panel of mouse monoclonal antibodies and rabbit polyclonal antisera that were raised to myelin-associated glycoprotein (MAG) were screened for reactivity with acidic glycolipids from brain and peripheral nerve by enzyme-linked immunosorbent assay (ELISA) and/or a thin-layer chromatogram overlay technique. Seven out of 7 mouse monoclonal antibodies that recognize carbohydrate epitopes in human MAG also reacted with acidic glycolipids from human and cat peripheral nerve, while monoclonal antibodies that react with polypeptide epitopes on MAG did not react with these glycolipids. Rabbit anti-human MAG antisera also strongly reacted with the glycolipids from peripheral nerve, while rabbit antisera raised to rat MAG did not. None of the antibodies reacted with similar glycolipid fractions prepared from adult human brain. Overlay of thin-layer chromatograms revealed that all the mouse and rabbit antibodies showing reactivity with peripheral nerve glycolipids were binding to the same two sphingoglycolipids that react with human anti-MAG IgM paraproteins in neuropathy and with HNK-1 (anti-Leu-7), a mouse IgM monoclonal antibody that identifies a subset of human lymphocytes with natural killer function. Thus, the carbohydrate epitope(s) in MAG which is shared with nerve acidic glycolipids appears to be highly immunogenic in mice and rabbits. Further, it is clear that the antibodies that react with the carbohydrate moieties of human MAG cannot be used as specific probes for this glycoprotein.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007694	Killer Cells, Natural	Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D009185	Myelin Proteins	MYELIN-specific proteins that play a structural or regulatory role in the genesis and maintenance of the lamellar MYELIN SHEATH structure.	Myelin Protein,Protein, Myelin,Proteins, Myelin
D010266	Paraproteins	Abnormal immunoglobulins synthesized by atypical cells of the MONONUCLEAR PHAGOCYTE SYSTEM. Paraproteins containing only light chains lead to Bence Jones paraproteinemia, while the presence of only atypical heavy chains leads to heavy chain disease. Most of the paraproteins show themselves as an M-component (monoclonal gammopathy) in electrophoresis. Diclonal and polyclonal paraproteins are much less frequently encountered.	Paraprotein
D010525	Peripheral Nerves	The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D006028	Glycosphingolipids	Lipids containing at least one monosaccharide residue and either a sphingoid or a ceramide (CERAMIDES). They are subdivided into NEUTRAL GLYCOSPHINGOLIPIDS comprising monoglycosyl- and oligoglycosylsphingoids and monoglycosyl- and oligoglycosylceramides; and ACIDIC GLYCOSPHINGOLIPIDS which comprises sialosylglycosylsphingolipids (GANGLIOSIDES); SULFOGLYCOSPHINGOLIPIDS (formerly known as sulfatides), glycuronoglycosphingolipids, and phospho- and phosphonoglycosphingolipids.
