C-Terminal Mutants of Apolipoprotein L-I Efficiently Kill Both Trypanosoma brucei brucei and Trypanosoma brucei rhodesiense
Apolipoprotein L-I (apoL1) is a human-specific serum protein that kills Trypanosoma brucei through ionic pore formation in endosomal membranes of the parasite. The T. brucei subspecies rhodesiense and gambiense resist this lytic activity and can infect humans, causing sleeping sickness. In the case of T. b. rhodesiense, resistance to lysis involves interaction of the Serum Resistance-Associated...
متن کاملTrypanosoma brucei brucei
Protein synthesis in Trypanosoma brucei brucei was rapidly inhibited during polyamine depletion by DL-adifluoromethylornithine (DFMO) in vitro and in vivo. [3H]Leucine incorporation was depressed 30-40 % by 24 h and 80-90 % by 48 h of DFMO treatment. Concomitantly there was an apparent decrease in the synthesis of the variant-specific glycoprotein (VSG) in DFMO-treated trypanosomes, as measured...
متن کاملActivity of bisphosphonates against Trypanosoma brucei rhodesiense.
We report the results of a comparative molecular field analysis (CoMFA) investigation of the growth inhibition of the bloodstream form of Trypanosoma brucei rhodesiense trypomastigotes by bisphosphonates. A quantitative three-dimensional structure-activity relationship CoMFA model for a set of 26 bisphosphonates having a range of activity spanning approximately 3 orders of magnitude (minimum IC...
متن کاملGlutathione derivatives active against Trypanosoma brucei rhodesiense and T. brucei brucei in vitro.
Diesters based on N-benzyloxycarbonyl-S-(2,4-dinitrophenyl) GSH (CBzGSDNP) containing linear alcohols 3 to 9, branched alcohols 10 to 20, or heteroatom linear alcohols 21 to 25, were investigated as in vitro inhibitors of pathogenic parasites. Diesters 3 to 25 were better inhibitors of Trypanosoma brucei rhodesiense than of T. brucei brucei and had low cytotoxicities. The most active compound h...
متن کاملProtein isoprenylation in Trypanosoma brucei brucei.
Trypanosoma brucei is a digenetic protozoan parasite presenting a public health hazard in certain areas of Africa; it is transmitted between mammals (bloodstream form (BSF)) by tsetse flies (procyclic form (PCF)). We have an ongoing interest in small GTP proteins in T. brucei, and these are commonly isoprenylated. Many isoprenylated proteins belong to the rab family and include ras; the isopren...
