Trypanosoma cruzi nucleoside triphosphate diphosphohydrolase 1 (TcNTPDase-1) bi...
Mariotini-Moura, Christiane; Bastos, Matheus Silva e; Castro, Felipe Freitas de; Trindade, Mellina Lanna; Vasconcellos, Raphael de SouzaPrevious work has suggested that Trypanosoma cruzi diphosphohydrolase 1 (TcNTPDase-1) may be involved in the infection of mammalian cells and serve as a potential target for rational drug design. In this work, we produced recombinant TcNTPDase-1 and evaluated its nucleotidase activity, cellular localization and role in parasite adhesion to mammalian host cells. TcNTPDase-1 was able to utilize a broad range of t...
Padrões de poliadenilação em moléculas de RNAs de Leishmania obtidas da análise...
Santos, Ramon de FreitasCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The high throughput next generation sequencing (NGS) has revealed new aspects on genomes and transcriptomes that was not observed or poor described using small scale sequencing. Using two species of Leishmania as a model in a typical transcriptome analysis and the NGS 454 pirosequencing we found non canonical polyadenilations at rRNAs and mRNAs. Leish...
Caracterização e avaliação da atividade ectonucleotidásica do Trypanosoma cruzi...
Santos, Ramon de FreitasPrograma de Pós-Graduação em Ciências Biológicas. Núcleo de Pesquisas em Ciências Biológicas, Pró-Reitoria de Pesquisa e Pós Graduação, Universidade Federal de Ouro Preto.; Neste trabalho foi avaliada a participação de ecto-nucleotidases, especialmente da família ENTPDase, na infecção in vitro pelo Trypanosoma cruzi. Foi demonstrado que diferentes cepas/clone apresentam atividade ecto-nucleotídásica diversa, po...

Influence of ecto-nucleoside triphosphate diphosphohydrolase activity on Trypan...
Santos, Ramon de Freitas; Pôssa, Marcela Auxiliadora Souza; Bastos, Matheus Silva e; Guedes, Paulo Marcos da Matta; Almeida, Márcia Rogéria deBackground: The protozoan Trypanosoma cruzi is the causative agent of Chagas disease. There are no vaccines or effective treatment, especially in the chronic phase when most patients are diagnosed. There is a clear necessity to develop new drugs and strategies for the control and treatment of Chagas disease. Recent papers have suggested the ecto-nucleotidases (from CD39 family) from pathogenic agents as importa...
