Immunological changes in canine peripheral blood leukocytes triggered by immuni...
Araújo, Márcio Sobreira Silva; Andrade, Renata Aline de; Avelar, Renato Sathler; Magalhães, Camila Paula; Carvalho, Andréa Teixeira deIn this study, we summarized the major phenotypic/functional aspects of circulating leuko-cytes following canine immunization with Leishvaccine and Leishmune ®. Our findings showed that Leishvaccine triggered early changes in the innate immunity (neutrophils and eosinophils) with late alterations on monocytes. Conversely, Leishmune ® induced early phenotypic changes in both, neutrophils and monocytes. Moreover,...
Despite Leishvaccine and Leishmune ® trigger distinct immune profiles, their ab...
Araújo, Márcio Sobreira Silva; Andrade, Renata Aline de; Vianna, Leonardo Rocha; Mayrink, Wilson; Reis, Alexandre Barbosa; Avelar, Renato SathlerPhenotypic features of peripheral blood leukocytes have been investigated as a prerequisite to characterize the protective immunity attributed to both Leishvaccine and Leishmune ® . Our results showed that either those vaccine were accompanied by distinct profiles on innate immune compartment. While Leishvaccine promoted early changes in phenotypic fea-tures of neutrophils and eosinophils with late involvement ...
T-cell-derived cytokines, nitric oxide production by peripheral blood monocytes...
Araújo, Márcio Sobreira Silva; Andrade, Renata Aline de; Avelar, Renato Sathler; Carvalho, Andréa Teixeira de; Andrade, Mariléia ChavesIt is generally accepted that distinct cytokine expression by the cellular immune response plays a critica role during the outcome of experimental as well as natural canine visceral Leishmaniasis (CVL). Despite the fact that immunoprophylaxis of CVL has become an important control strategy and protective immunity has been reported upon immunization with whole as well as purifiedLeishmaniaantigens, the cytokine ...
Clinical value of anti-Leishmania (Leishmania) chagasi IgG titers detected by f...
Andrade, Renata Aline de; Reis, Alexandre Barbosa; Gontijo, Célia Maria Ferreira; Braga, Lidiane Bento; Rocha, Roberta Dias RodriguesLeishmune® vaccination covers a broader number of endemic areas of canine visceral leishmaniasis (CVL) and therefore the development of new serological devices able to discriminate CVL from Leishmune® vaccinees becomes an urgent need considering the post-vaccine seroconversion detected throughout conventional methodologies. Herein, we have described the establishment of a flow cytometry based methodology to det...
