Release and purification of trypanosoma brucei variant surface glycoprotein

Journal of Cellular Biochemistry, 1984
AbstractConditions affecting the solubilization of variant surface glycoprotein (VSG) from Trypanosoma brucei have been investigated. The results obtained form the basis for a convenient and efficient method for VSG purification. VSG release from the cell surface was temperature‐dependent, following osmotic lysis at 0 °C, and was inhibited by low ...

Topological analysis of antigenic determinants on a variant surface glycoprotein of Trypanosoma brucei

Molecular and Biochemical Parasitology, 1984
Nine monoclonal antibodies specific for the variant surface glycoprotein (VSG) of Trypanosoma brucei MITat 1.6 have been produced and characterised as part of a coordinated project to define the three dimensional structure and immunological profile of this and other VSG molecules. Competition radioimmunoassays using all combinations of these antibodies

The membrane form of variant surface glycoproteins of Trypanosoma brucei

Nature, 1983
African trypanosomes are parasitic protozoa which are enveloped by a surface coat consisting of a matrix of identical glycoprotein molecules. Variations in the composition of these variant surface glycoproteins (VSGs) allow the parasite to escape the host's immune system and render effective immunoprophylaxis improbable. However, underlying the surface

The variant surface glycoprotein as a tool for adaptation in African trypanosomes [PDF]

Microbes and Infection, 2006
African trypanosomes (prototype: Trypanosoma brucei) are flagellated protozoan parasites that infect a wide variety of mammals, causing nagana in cattle and sleeping sickness in humans. These organisms can cause prolonged chronic infections due to their ability to successively expose different antigenic variants of the variant surface glycoprotein (VSG)

Solution properties of the variant surface glycoprotein of Trypanosoma brucei

Molecular and Biochemical Parasitology, 1986
The solution properties of the membrane form and soluble form of variant surface glycoproteins from Trypanosoma brucei have been compared. Solution cross-linking studies established that both forms are dimers, although dissociation of membrane-form variant surface glycoprotein can be promoted by certain ionic and zwitterionic detergents.

A structural motif in the variant surface glycoproteins of Trypanosoma brucei

Nature, 1993
The variable domain of the trypanosome variant surface glycoprotein (VSG) ILTat 1.24 has been shown by X-ray crystallography to resemble closely the structures of VSG MITat 1.2, despite their low sequence similarity. Specific structural features of these VSGs, including substitution of carbohydrate for an alpha-helix, can be found in other VSG ...
