Dogs are the primary reservoir for Leishmania parasites. The immune response induced by Leishmania infantum infection in these animals has not been completely elucidated, and few studies have investigated the relationship between the expression levels of chemokines and chemokine receptors and the clinical status of dogs with canine visceral leishmaniasis(More)
Chemokines and chemokine receptors interaction have presented important role in leukocyte migration to specific immune reaction sites. Recently, it has been reported that chemokine receptors CXC (CXCR3) and CC (CCR5) were preferentially expressed on Th1 cells while CCR3 and CCR4 were preferentially expressed on Th2 cells. This study evaluated the mRNA(More)
Chronic chagasic cardiomyopathy affects 20% of Chagas' disease patients. At present, Chagas' disease chemotherapy uses nitrofurans, benznidazole (Rochagan®, Rodanil®, Roche) or nifurtimox (Lampit®, Bayer). Treatment during acute and recent chronic phases in childhood effects 71.5% and 57.6%, respectively, of parasitological cure. However, in clinical trials(More)
Ischemic strokes have been implicated as a cause of death in Chagas disease patients. Inflammation has been recognized as a key component in all ischemic processes, including the intravascular events triggered by vessel interruption, brain damage and repair. In this study, we evaluated the association between inflammatory markers and the death risk (DR) and(More)
Dogs are the primary urban reservoir of Leishmania infantum and play a crucial role in the transmission of this parasite to man via sandflies. The spleen and liver are the main target organs of L. infantum infection, but few studies have evaluated the immune response to this infection in the canine liver. To identify the immunological mediators involved in(More)
