O objetivo deste estudo é fornecer informações para essas lacunas. Nós investigamos a cinética do antimoniato de meglumina (AM) em macacos Rhesus; avaliamos a transferência para o leite materno e lactentes quando ratas lactantes foram tratadas com AM; e estudamos a expressão e atividade de citocromos P450 (CYP) hepáticos em ratos machos tratados com AM. Macacos Rhesus foram tratados com injeções diárias intramusculares durante 21 diasconsecutivos e os níveis de antimônio no sangue, durante e após o tratamento, foram determinados. Níveis de antimônio residual (24 ou 48 horas) após a última injeção foram maiores em hemácias que no plasma. Tireóide, fígado, baço, vesícula, pulmões, pele e rins apresentaram níveis detectáveis de antimônio 60 dias após o fim dotratamento. Níveis detectáveis de antimônio foram encontrados no leite materno de ratas Wistar tratadas por via subcutânea com AM. As ninhadas das mães tratadas também apresentaram níveis detectáveis de Sb, sugerindo que o antimônio é transferido para o leite e absorvido pelos filhotes. Ratos machos adultos foram tratados com AM (300 mgSbV/ kg peso corpóreo/dia por via subcutânea) ou apenas com o veículo, durante 20 dias. As atividades de etoxiresorufina-O-desetilase (EROD), benziloxiresorufina-Odesbenzilase(BROD) erithromicina N-desmetilase (END) (marcadores de CYP1A1/2,CYP2B1/2 e CYP3A, respectivamente) estavam diminuídas nos microssomos hepáticos de ratos tratados com AM. Uma vez que as atividades de N-nitrosodimeilamina desmetilase (NDMA) e anilina 4-hidroxilase (A4H), marcadores de CYP2E1, estavamdiminuídas e a de p-nitrofenol-hidroxilase (PNPH) estava aumentada, sugerimos que a PNPH no fígado de ratos seja catalisada não somente CYP2E1, mas outras isoformas deCYP. As alterações encontradas e os resultados de immunoblotting e PCR real-time sugerem que o tratamento com AM altera as atividades de CYP através de mecanismos pós-traducionais.

Individual dispersal decisions affect fitness via maternal rank effects in male rhesus macaques

Weiß, Brigitte M., Kulik, Lars, Ruiz-Lambides, Angelina V., Widdig, Anja 07 September 2016 (has links) (PDF)
Natal dispersal may have considerable social, ecological and evolutionary consequences. While speciesspecific dispersal strategies have received much attention, individual variation in dispersal decisions and its fitness consequences remain poorly understood. We investigated causes and consequences of natal dispersal age in rhesus macaques (Macaca mulatta), a species with male dispersal. Using long-term demographic and genetic data from a semi-free ranging population on Cayo Santiago, Puerto Rico, we analysed how the social environment such as maternal family, group and population characteristics affected the age at which males leave their natal group. While natal dispersal age was unrelated to most measures of group or population structure, our study confirmed earlier findings that sons of high-ranking mothers dispersed later than sons of low-ranking ones. Natal dispersal age did not affect males\\\' subsequent survival, but males dispersing later were more likely to reproduce. Late dispersers were likely to start reproducing while still residing in their natal group, frequently produced extra-group offspring before natal dispersal and subsequently dispersed to the group in which they had fathered offspring more likely than expected. Hence, the timing of natal dispersal was affected by maternal rank and influenced male reproduction, which, in turn affected which group males dispersed to.

Rio de Janeiro, RJ, Brasil. / Para desvendar a fisiopatologia da leishmaniose humana, é necessário um melhor entendimento de como a Leishmania é capaz de sobreviver por anos em granulomas imunologicamente ativos. Neste estudo, utilizamos o modelo de infecção macaco Rhesus-Leishmania braziliensis (Macaca mulatta) de leishmaniose cutânea (LC), como um meio de avaliar a utilidade do sistema primata no estudo da resposta inflamatória crônica granulomatosa desenvolvida pelo hospedeiro tanto na forma auto-resolutiva quanto na forma persistente da doença. Nossos achados reforçam a noção de que existe uma interação entre o sistema imune do hospedeiro e a capacidade patogênica do parasita no resultado clínico da infecção por Leishmania. De acordo com os casos documentados de LC em humanos induzida por L.braziliensis, as infecções experimentais neste modelo induzem a célula “T-helper” tipo 1 (Th1) mediando-a inflamação e levando a formação de granulomas bem organizados, consistindo de todos os tipos celulares específicos encontrados nos granulomas humanos. Nós mostramos que os leucócitos polimorfonucleares são decisivos para controle do parasita nos eventos iniciais da inflamação in vivo. Ademais, fagócitos mononucleares que fagocitam granulócitos apoptóticos parasitados parecem ser a chave principal no estabelecimento da infecção nos macacos. A formação do granuloma verificada nos animais é direcionada por diversos mediadores inflamatórios que são importantes para o desenvolvimento das células Th1 e da função de macrófagos efetores. A análise cinética da resposta inflamatória revelou variados marcadores fenotípicos de células positivas para CD3, CD4, CD8, CD20, CD68, Foxp3 e HLA-DR. Digno de nota, agregados de células B CD20+ foram encontrados na lesão crônica, o qual serve como um substrato morfológico para orquestrarem ou modularem o desenvolvimento da resposta duradoura na infecção persistente. Nossos achados indicam que ambos os subgrupos de células regulatórias CD4 Foxp3+ e Foxp3- expressando interleucina-10 previne a erradicação da L. braziliensis da pele inflamada, desse modo, suprimindo uma eventual resposta curativa em macacos com LC persistente. Esses resultados apontam a viabilidade do uso desse modelo para elucidar, totalmente, os mecanismos moleculares das células t regulatórias mediadoras da supressão na resposta imune efetora, resultando assim o crescimento descontrolado do granuloma durante a leishmaniose, o que é necessário ser considerado em qualquer estratégia proposta para o controle terapêutico dessa importante doença inflamatória. / In order to unravel the physiopathology of leishmaniasis in humans, it is necessary to better understand how Leismania are able to survive for years within immunologicallyactive granulomas. In the present study, we used a Leishmania braziliensis-macaque (Macaca mulatta) infection model of cutaneous leishmaniasis (CL) as a means of assessing the usefulness of this primate system to study the host inflammatory granulomatous response involved in both healing and non-healing forms of the disease. Our findings reinforce the notion that an interplay exists between the host immune system and the pathogenic capability of the parasite in the clinical outcome of leishmanial infection. Consistent with documented cases of human L. braziliensis CL, experimental infections induced a T-helper cell type 1 (Th1)-mediated inflammation leading to the formation of well organized granulomas, consisting of all the specific cell types found within human granulomas. We provide evidence that polymorphonuclear neutrophil leukocytes are decisive for parasite containment by early inflammatory events in vivo. Furthermore, scavenger mononuclear phagocytes engulfing most of the parasite-laden apoptotic granulocytes are likely to be key players in establishing the infection in macaques. We show that granuloma formation in macaques is orchestrated by diverse inflammatory mediators that are important for Th1-cell development and macrophage effector functions. A kinetic analysis of the inflammatory response revealed marked variation in the number of positive cells for CD3, CD4, CD8, CD20, CD68, Foxp3, and HLA-DR phenotypes. Of note, CD20+ dense B-cell aggregates were found in chronic lesions, which might serve as a morphological substrate for the orchestration of the enduring host response to persistent infection. Our findings indicate that both Foxp3+ and Foxp3- CD4+ regulatory T-cell (Treg) subsets expressing interleukin-10 might prevent clearance of L. braziliensis from the inflamed skin, thereby eventually suppressing the healing response in macaques with long-standing CL. These results point to the feasibility of using this model to fully elucidate the molecular mechanisms of Treg-mediated suppression leading to the uncontrolled growth of granulomas occurring in leishmaniasis, which will need to be considered in any strategy designed for therapeutic control of this important inflammatory disease.
