An Overview of Trypanosoma brucei Infections: An Intense Host–Parasite Interaction [PDF]

open access: yes, 2016
Trypanosoma brucei rhodesiense and T. brucei gambiense, the causative agents of Human African Trypanosomiasis, are transmitted by tsetse flies. Within the vector, the parasite undergoes through transformations that prepares it to infect the human host ...

Structural analysis of the variable major proteins of Borrelia hermsii. [PDF]

open access: yes, 1983
Borrelia hermsii undergoes spontaneous antigenic variation in vivo and in vitro. Serotype specificity is associated with expression of one of a family of molecular weight-variable proteins, the pI proteins.

Expression site attenuation mechanistically links antigenic variation and development in Trypanosoma brucei [PDF]

open access: yes, 2014
We have discovered a new mechanism of monoallelic gene expression that links antigenic variation, cell cycle, and development in the model parasite Trypanosoma brucei. African trypanosomes possess hundreds of variant surface glycoprotein (VSG) genes, but

Characterization of an African trypanosome mutant refractory to lectin-induced death [PDF]

open access: yes, 2015
Incubation of African trypanosomes with the lectin concanavalin A (conA) leads to alteration in cellular DNA content, DNA degradation, and surface membrane blebbing.

The interaction of Trypanosoma congolense with endothelial cells [PDF]

open access: yes, 2017
Factors which affect adhesion of cultured Trypanosoma congolense bloodstream forms to mammalian feeder cells have been examined. Using an in vitro binding assay, the initial events following interaction of trypanosomes with bovine aorta endothelial (BAE)

Trypanosoma brucei: Release of variant surface glycoprotein during the parasite life cycle

open access: yesExperimental Parasitology, 1986
African trypanosome variant surface antigen, which was released from the Trypanosoma brucei parasite at two stages in its life cycle, has been characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis in the presence of 4 M urea. Variant surface antigen released as exoantigen into the bloodstream of infected rats resembled the soluble ...

The genetics and genomics of Trypanosoma cruzi [PDF]

open access: yes, 2007
Trypanosoma cruzi is a kinetoplastid parasite that causes Chagas disease. Trypanosomes are unusual organisms in many aspects of its genetics and molecular and cellular biology and considered a paradigm of the exception of the rule in the eukaryotic ...

Bidirectional silencing of RNA polymerase I transcription by a strand switch region in Trypanosoma brucei [PDF]

open access: yes, 2017
The procyclin genes in Trypanosoma brucei are transcribed by RNA polymerase I as part of 5-10 kb long polycistronic transcription units on chromosomes VI and X.

Variant surface glycoprotein synthesis and cell cycle progression in Trypanosoma brucei

open access: yes, 2011
The unicellular eukaryote Trypanosoma brucei causes African Sleeping sickness and multiplies extracellularly in the bloodstream of the infected host. The parasite evades antibody-mediated lysis by switching its Variant Surface Glycoprotein (VSG) coat. Blocking VSG synthesis results in an abrupt growth inhibition and a precise pre-cytokinesis cell cycle
