Most African trypanosomes, including the veterinary species Trypanosoma brucei brucei and T. congolense are susceptible to lysis by human serum. A recent study by Alsford et al. [PLoS Pathogens (2014) 10, e1004130] has identified a T. b. brucei lysosomal cathepsin with an inhibitory effect on human serum's trypanolytic action.

brucei is imported into mitochondria.

N-Ribohydrolases, including the inosine-adenosine-guanosine-preferring (IAG) nucleoside hydrolase, have been proposed to be involved in the nucleoside salvage pathway of protozoan parasites and may constitute rational therapeutic targets for the treatment of these diseases. Reported is the complete sequence of the Trypanosoma brucei brucei iagnh gene, which encodes IAG-nucleoside hydrolase. The...

Trypanosoma brucei rhodesiense was named after Rhodesia which, in turn, the British imperialist and white supremacist Cecil Rhodes. In light of Black Lives Matter movement contemporary consciousness postcolonial legacy, it seems opportune to reconsider subspecies name. Pros cons renaming T. b. are discussed.

African trypanosomes contain a membrane-bound enzyme capable of removing dimyristylglycerol from the membrane-attached form of the variable surface glycoprotein (mfVSG; Ferguson, M. A. J., K. Halder, and G. A. M. Cross, 1985, J. Biol Chem., 260:4963-4968). Although mfVSG phospholipase-C has been implicated in the removal of the VSG from the trypanosome surface (Cardoso de Almeida, M. L., and M....

Glycogen synthase kinase 3 (GSK3) is a genetically validated drug target for human African trypanosomiasis (HAT), also called African sleeping sickness. We report the synthesis and biological evaluation of aminopyrazole derivatives as Trypanosoma brucei GSK3 short inhibitors. Low nanomolar inhibitors, which had high selectivity over the off-target human CDK2 and good selectivity over human GSK3...

BACKGROUND Trypanosoma brucei (T b) gambiense is targeted to reach elimination as a public health problem by 2020 and full elimination by 2030. To achieve these goals, stakeholders need to consider strategies to accelerate elimination. Hence, we aimed to model several options related to current and emerging methods for case detection, treatment, and vector control across settings to assess cost...

phytochemical investigation of a dichloromethane-methanol (1:1) extract of the fruit pericarp of omphalocarpum procerum which exhibited antiplasmodial activity during preliminary screening led to the isolation of the new fatty ester triterpenoid 3β-hexadecanoyloxy-28-hydroxyolean-12-en-11-one (1), together with five known compounds 2-6. the structure of the new compound as well as those of the ...

The transferrin receptor of Trypanosoma brucei (TbTfR) is a heterodimer glycosylphosphatidylinositol (GPI)-anchored ESAG6 subunit and an ESAG7 subunit. To investigate whether the GPI-anchor essential for function TbTfR, with transmembrane domain instead (ESAG6tmd) was inducibly expressed in bloodstream form trypanosomes. It shown that ESAG6tmd able to dimerise TbTfR can bind transferrin. Fracti...
