Morphology of spermatozoa of Dissomphalus connubialis (Ashmead, 1893) (Hymenopt...
Oliveira, Claudia Miranda de; Fraga, Felipe Bertholdi; Brito, Pedro; Gomes, Luiz Fernando; Dolder, Heidi; Lino-Neto, JoséIn this study, the morphology of spermatozoa of Bethylidae Dissomphalus connubialis (Pristocerinae) was analyzed using light and transmission electron microscopy. Spermatozoa of this species are thin, measure approximately 130 μm in length and comprise a head region and flagellum region. The head is formed by the acrosome and nucleus. The acrosome consists of the acrosome vesicle and the perforatorium, the post...
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...

Vasconcellos, Raphael De Souza; Mariotini-Moura, Christiane; Gomes, Rodrigo Saar; Serafim, Tiago Donatelli; Firmino, Rafaela de CássiaVisceral leishmaniasis is an important tropical disease, and Leishmania infantum chagasi (synonym of Leishmania infantum) is the main pathogenic agent of visceral leishmaniasis in the New World. Recently, ecto-nucleoside triphosphate diphosphohydrolases (E-NTPDases) were identified as enablers of infection and virulence factors in many pathogens. Two putative E-NTPDases (∼70 kDa and ∼45 kDa) have been found in ...
