When the infected mammalian host of Trypanosoma brucei brucei is injected with a solution of the iron chelator salicyl hydroxamic acid and glycerol, the aerobic and anaerobic glucose catabolism of the parasite is blocked and the parasite is rapidly destroyed.
Current treatments available for African sleeping sickness or human African trypanosomiasis (HAT) are limited, with poor efficacy and unacceptable safety profiles. Here, we report a new approach to address treatment of this disease based on the use of compounds that bind to parasite surface glycans
The neglected tropical diseases Human African Trypanosomiasis and leishmaniasis are caused by infection with trypanosomatid parasites Trypanosoma brucei and Leishmania spp, respectively. The genomes of these organisms contain multiple putative G-quadruplex (G4) forming sequences which have recently
Human African trypanosomiasis is a major health problem in large regions of Africa. Current chemotherapeutic options are limited and far from ideal. A diverse range of drug targets has been identified and validated in trypanosomes. These include several organelles (glycosomes, acidocalcisomes,
In mice, experimental infection with Trypanosoma brucei causes decreased bone marrow B-cell development, abolished splenic B-cell maturation and loss of antibody mediated protection including vaccine induced memory responses. Nothing is known about this phenomenon in human African trypanosomiasis
The members of the subfamily Triatominae (Hemiptera: Reduviidae) comprise a great number of species of medical importance in the transmission of the T. cruzi (American trypanosomiasis). The aim of this study was to contribute to the knowledge about the chemical composition in proteins, lipids,
Infections by parasitic protozoans and helminths are a major world-wide health concern, but no vaccines exist to the major human parasitic diseases, such as malaria, African trypanosomiasis, amebiasis, leishmaniasis, schistosomiasis, and lymphatic filariasis. Recent studies on a number of parasites
Human African trypanosomiasis, or sleeping sickness, is a lethal disease caused by the protozoan parasite Trypanosoma brucei. However, although many efforts have been made to understand the biochemistry of this parasite, drug development has led to treatments that are of limited efficiency and of
Variable surface antigens of cloned populations of African trypanosomes were studied using 2-dimensional gel electrophoresis and monoclonal antibodies. Two-dimensional gel maps showed that the only major differences in protein profiles of the non-nuclear materials from different clones of
The onset of a pneumonia by P. carinii in AIDS patients have force scientist to look for others therapies against this parasite. It is more necessary when the first line treatment which is cotrimoxazol produced secondary effects or not therapeutic effects. Pentamidine which is an agent usually used
Galectin-3 is the best characterized member of galectins, an evolutionary conserved family of galactosides-binding proteins that play central roles in infection and immunity, regulating inflammation, cell migration, and cell apoptosis. Differentially expressed by cells and tissues with immune
African trypanosomiasis is a deadly disease for which few chemotherapeutic options are available. The causative agents, Trypanosoma brucei rhodesiense and T. b. gambiense, utilize a non-cytochrome, alternative oxidase (AOX) for their cellular respiration. The absence of this enzyme in mammalian
