Instituto de Bioquímica Médica. Centro de Ciências da Saúde. Rio de Janeiro, RJ, BrasilThe presence of Leishmania amazonensis ecto-nucleoside triphosphate triphosphohydrolase activities was demonstrated using antibodies against different NTPDase members by Western blotting, flow cytometry, and immunoelectron microscopy analysis. Living promastigote cells sequentially hydrolyzed the ATP molecule generating ADP, AMP, and adenosine, indicating that this surface enzyme may play a role in the salvage of purines from the extracellular medium. The L. amazonensis ecto-NTPDase activities were insensitive to Triton X-100, but they were enhanced by divalent cations, such as Mg(2+). In addition, the ecto-NTPDase activities decreased with time for 96 h when promastigotes were grown in vitro. On the other hand, these activities increased considerably when measured in living amastigote forms. Furthermore, the treatment with adenosine, a mediator of several relevant biological phenomena, induced a decrease in the reactivity with anti-CD39 antibody, raised against mammalian E-NTPDase, probably because of down regulation in the L. amazonensis ecto-NTPDase expression. Also, adenosine and anti-NTPDase antibodies induced a significant diminishing in the interaction between promastigotes of L. amazonensis and mouse peritoneal macrophages.Leishmania amazonensisEcto-ATPaseAdenosineE-NTPDaseAdenosina Trifosfatases/metabolismoLeishmania mexicana/enzimologiaDifosfato de Adenosina/metabolismoMonofosfato de Adenosina/metabolismoTrifosfato de Adenosina/metabolismoAnimaisAntígenos CD/metabolismoApirase/metabolismoWestern BlottingFemininoCitometria de FluxoHumanosLeishmaniose Cutânea/parasitologiaMacrófagos Peritoneais/parasitologiaCamundongosMicroscopia ImunoeletrônicaPirofosfatases/metabolismoinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZPinheiro, Carla MonicaDuarte, Erica dos Santos MartinsFerraro, Rodrigo BarbosaSouza, André Luíz Fonseca deGomes, Marta T.Lopes, Angela H.c.sSantos, Marcos André Vannier dosSantos, André L.sFernandes, José Roberto MeyerORIGINALPinheiro CL Leishmania....pdfPinheiro CL Leishmania....pdfapplication/pdf699593https://arca.fiocruz.br/bitstreams/a13f2306-6af3-4eea-a130-321010c464f1/download0388d5cd0021553b77b5437f2f674237MD52trueAnonymousREADLICENSElicense.txtlicense.txttext/plain;
